35 Essential Thought Leaders Globally on Microfinance

Introduction

The most radical idea in modern finance is deceptively simple: poor people are creditworthy. It took a Bangladeshi economist in the 1970s to prove it at scale, a Nobel Peace Prize to broadcast it to the world, and several decades of sometimes painful evidence-gathering to understand when it works and when it falls short. The global microfinance industry now serves more than 150 million borrowers across more than 100 countries, with a market valued at approximately USD 326 billion in 2026 and forecast to exceed USD 813 billion by 2034. Those numbers tell part of the story. The rest is written in the faces of women in Pakistan, Kenya, India, and Bolivia who used small loans to build businesses, educate their children, and move beyond the reach of poverty.

But microfinance is not a simple story of triumph. The field has also been shaped by debt crises in Andhra Pradesh and Nicaragua, by honest researchers who found that RCT evidence on poverty impact was weaker than advocates claimed, and by the uncomfortable question of what happens when for-profit motives crowd out client welfare. The thought leaders who have shaped this field have not all agreed with each other. Several of the most important voices on this list built their reputations precisely by questioning what everyone else was saying.

The World Bank's Global Findex 2025 found that 77 percent of women globally now hold a financial account, yet a persistent gender gap remains in low- and middle-income countries, with women in some of the most affected economies still substantially less likely to own one than men. That gap is where much of the most urgent microfinance work is concentrated. Understanding who is driving the thinking and the practice in this space, and following their work, is one of the most direct ways that leaders in finance, development, and social enterprise can stay oriented to what actually works.

This list brings together 35 thought leaders whose work has genuinely shaped the global microfinance conversation. These are the researchers who produced the evidence, the practitioners who built institutions serving millions, the critics who kept the sector honest, and the digital innovators who are remaking what microfinance can look like in the mobile age. The list deliberately moves past the household names that appear on every financial inclusion roundup to surface voices who are actively publishing, building, and engaging in 2025 and 2026. Several of the most important names here will be unfamiliar to readers outside the sector. That unfamiliarity is entirely the point.

Jonno White is a Certified Working Genius Facilitator, bestselling author of Step Up or Step Out (10,000+ copies sold globally), and leadership consultant who works with leadership teams in financial services organisations and nonprofits around the world. To bring Jonno in to work with your leadership team on the communication, decision-making, and people challenges that accompany rapid organisational growth, email jonno@consultclarity.org.

Why Microfinance Thought Leadership Matters

The practitioner who builds a microfinance institution without engaging with the research is flying blind. The researcher who publishes without engaging with practitioners produces findings that never reach the people who could use them. The policymaker who regulates without understanding client welfare creates systems that serve institutions rather than borrowers. The entire history of microfinance is a cautionary tale about what happens when these three communities stop talking to each other.

The Andhra Pradesh microfinance crisis of 2010, in which aggressive lending practices by for-profit MFIs drove thousands of borrowers into a spiral of multiple loans and coerced repayments, was not a surprise to everyone who saw it coming. The thought leaders on this list include people who had been warning about these dynamics for years. Their work is not abstract. It has direct implications for whether microfinance clients are made better or worse off by the institutions that claim to serve them.

Following the right voices in this space gives you access to a level of sector-specific intelligence that general financial media simply does not provide. The Global Findex data, the 60 Decibels Microfinance Index, the CGAP research briefs, the e-MFP Financial Inclusion Compass, and the hundreds of practitioner blogs and academic papers produced each year represent a body of knowledge that the 35 people on this list are actively producing, synthesising, and challenging. Organisations working at the intersection of finance, poverty, and technology ignore that body of knowledge at their peril.

For organisations building leadership and team capacity, Jonno White works with leadership teams navigating the decision-making and communication challenges that accompany mission-driven organisations under pressure. International travel is often far more affordable than organisations expect. To discuss how Jonno might support your team, email jonno@consultclarity.org.

How This List Was Compiled

Every person on this list was selected on three criteria. First, substantive contribution to the field, demonstrated through published research, institutional leadership, policy work, or technology innovation that has measurably shaped how the global microfinance and financial inclusion sector thinks and operates. Second, active engagement in current sector conversations, with public work continuing into 2025 and 2026. Third, deliberate inclusion of voices that the casual reader is unlikely to have encountered on the standard financial inclusion roundup.

Geographic and disciplinary diversity were both priorities. The voices here come from Bangladesh, Pakistan, India, the United States, the United Kingdom, France, Belgium, Luxembourg, Kenya, Francophone Africa, Latin America, and beyond, and span economics, anthropology, finance, policy, technology, and direct practice. The list deliberately moved past the most prominent household names whose work has already shaped adjacent fields to surface fresher voices whose focus is specifically microfinance and financial inclusion.

Category 1: The Pioneers

The people who built the conceptual and institutional foundations of modern microfinance. These individuals did not just work in microfinance. They created the conditions that made the field possible. Their ideas about the creditworthiness of the poor, the design of group-lending systems, and the institutional structures needed to deliver financial services at scale became the foundational texts of the entire movement. Understanding their work is where any serious engagement with microfinance must begin.

1. Muhammad Yunus

Yunus Centre, Bangladesh

Few people have done more to reshape the way the world thinks about poverty than the founder of Grameen Bank and recipient of the 2006 Nobel Peace Prize. Muhammad Yunus began lending small amounts to poor women in Jobra village in Bangladesh in the mid-1970s, working from the conviction that poor people were not poor because they lacked intelligence or ambition, but because they lacked access to capital on reasonable terms. The institution he built from that experiment, the Grameen Bank, has served millions of borrowers and inspired microfinance institutions in more than 100 countries.

Yunus served as Chief Adviser of Bangladesh's interim government from August 2024 until February 2026, when he stepped down following national elections and returned to the Yunus Centre. His concept of social business, articulated in books including Building Social Business, offers a framework for how market mechanisms can be directed toward human welfare without requiring charitable subsidy. No list of microfinance thought leaders is complete without him, and no honest list would pretend his ideas have been without controversy: the commercialisation of microfinance that followed in his wake is something he has consistently criticised as a distortion of the original mission.

2. Alex Counts

Grameen Foundation, USA

Alex Counts spent a decade as a Fulbright scholar in Bangladesh training under Muhammad Yunus before founding Grameen Foundation in 1997 with a $6,000 seed grant from Yunus himself. Over the 18 years he led the organisation, Grameen Foundation grew from a tiny advocacy group into a global force for technology-enabled poverty reduction. Counts' book Small Loans, Big Dreams: Grameen Bank and the Microfinance Revolution in Bangladesh, America and Beyond, updated in a 2022 edition, remains one of the most rigorous and readable accounts of how the microfinance movement actually happened.

Counts continues to write, teach, and advocate from his base as an adjunct professor at the University of Maryland School of Public Policy, where he teaches courses on social entrepreneurship and international development. His blog and public commentary wrestle honestly with the gap between what microfinance promised and what the evidence has shown, making him a rare voice who combines deep insider knowledge with genuine willingness to acknowledge complexity. His most recent work focuses on how the Grameen family of organisations can coordinate more effectively to preserve Muhammad Yunus's founding mission as the sector evolves.

3. Elisabeth Rhyne

Center for Financial Inclusion at Accion (Founding Managing Director, 2008-2019), USA

The founding Managing Director of the Center for Financial Inclusion at Accion from the organisation's launch in 2008 until her retirement in 2019, Elisabeth Rhyne spent four decades at the intersection of microfinance policy, practice, and research. As a former director of microenterprise development at USAID and then a long-serving senior vice president at ACCION International before building CFI, she was present at virtually every major inflection point in the field's evolution.

Her book Mainstreaming Microfinance: How Lending to the Poor Began, Grew, and Came of Age in Bolivia, published by Kumarian Press in 2001, is one of the defining accounts of how microfinance institutionalised and commercialised. Her decade of work at CFI focused on moving the field beyond loan-centred approaches toward a broader vision of financial health for low-income clients, a shift that has become central to how the sector understands its own purpose. Since her retirement from CFI, she has continued writing and advising in the sector she helped build.

4. Roshaneh Zafar

Kashf Foundation, Pakistan

After a chance meeting with Muhammad Yunus at a conference in Islamabad in the early 1990s and a subsequent visit to Grameen Bank in Bangladesh, Roshaneh Zafar founded Pakistan's first specialised microfinance institution with a $10,000 loan from Yunus himself. The Kashf Foundation, whose name means "a process of self-discovery," has since served over one million women, floating Pakistan's first gender bond and pioneering a holistic approach to women's financial inclusion that goes well beyond credit.

Zafar is a recipient of Pakistan's Tamgha-i-Imtiaz civilian honour and the Skoll Foundation's Social Entrepreneurship Award. She has served on the World Economic Forum's Global Agenda Council on the Gender Gap and as a member of the United Nations Advisors Group on Inclusive Financial Sectors. Her consistent focus on building women's economic agency in one of the world's most challenging operating environments makes her one of the most consequential practitioners in the global microfinance movement.

Category 2: The Practitioners

Leaders who have built and led institutions serving millions of clients. These thought leaders are not primarily theorists. They run, or have run, organisations that move real money to real borrowers in challenging environments. Their credibility comes from operational experience, and their thinking is shaped by the daily reality of managing microfinance institutions at scale.

5. Graham A.N. Wright

MSC (MicroSave Consulting), UK/India/global

Graham Wright founded MicroSave in 1998, building it over 25 years into one of the world's leading financial inclusion consultancies with more than 300 staff working across 68 countries. The organisation he created has touched the lives of over 875 million people through its advisory, research, and capacity-building work with financial service providers, policymakers, and technology companies across Africa, Asia, and beyond.

Wright's book MicroFinance Systems: Designing Quality Financial Services for the Poor, published by Zed Books in 2000, remains a foundational practitioner text. He has published more than 70 peer-reviewed papers and developed 14 training toolkits. In December 2025, he co-founded the Alliance for Inclusive AI with BFA Global and Caribou Digital, focused on ensuring AI development serves the interests of low-income communities rather than reproducing existing inequalities. His LinkedIn activity is consistent and substantive, making him one of the most accessible voices in inclusive finance for practitioners looking to understand the intersection of technology and financial inclusion.

6. Andrée Simon

FINCA International, USA

Andrée Simon became Global CEO of FINCA International on 1 January 2023, succeeding the late Rupert Scofield. Under her leadership, FINCA operates across more than 40 countries with a mission of ending poverty through sustainable, scalable solutions driven by the insights and needs of people in the communities where they live. Simon first joined FINCA in 2001 as Deputy to the President and CEO, played a pivotal role in redesigning FINCA's microfinance business into a sustainable double bottom line operation, and served from 2016 to 2023 as President and CEO of FINCA Impact Finance, the global network of community-based microfinance banks.

Her leadership style combines corporate strategy depth, drawn from her earlier work at the Center for Strategic and International Studies and an MBA from the Wharton School, with two decades of operational responsibility for microfinance institutions in difficult markets. Simon has written and spoken extensively on financial inclusion for women and other financially excluded groups, including a 2025 fireside chat at the London Business School Wheeler Institute Social Impact Conference in which she argued that poverty is a result of systemic inefficiencies rather than lack of ability or effort. Her ongoing work positions FINCA as one of the most operationally credible voices on responsible microfinance globally.

7. Mary Ellen Iskenderian

Women's World Banking, USA

Mary Ellen Iskenderian has led Women's World Banking, the world's largest network of microfinance institutions and banks focused on women, since 2006. Under her leadership, the organisation has expanded its global reach, built an asset management arm that makes direct equity investments in financial service providers, and consistently positioned women's financial inclusion at the centre of the global development agenda.

Her book There's Nothing Micro About a Billion Women: Making Finance Work for Women, published by MIT Press in April 2022, makes a central argument that has become increasingly mainstream in the sector: microfinance is not sufficient for women's financial inclusion, and the field must evolve from small loans to a comprehensive approach encompassing savings, insurance, digital payments, and credit that matches women's actual economic lives. Her writing in Forbes, the Wall Street Journal, and Harvard Business Review has brought this argument to audiences far beyond the microfinance specialist community.

8. Alfred Hannig

Alliance for Financial Inclusion (AFI), Malaysia/global

Alfred Hannig has served as the CEO of the Alliance for Financial Inclusion since the organisation's founding in 2008, working from AFI's Kuala Lumpur headquarters. AFI is a global network of financial policymaking and regulatory institutions from more than 90 developing and emerging market countries dedicated to providing the world's unbanked with safe access to the formal financial system. Hannig holds a PhD in financial sector reform from Freie Universitat Berlin and has authored multiple publications on financial inclusion policy, regulatory design, and microfinance.

What distinguishes Hannig in a field crowded with advocates is his focus on the supply side: the regulatory and policy environments that either enable or constrain financial inclusion. His work at AFI has produced the Maya Declaration, the Maputo Accord, and other international frameworks through which member governments have made measurable commitments to financial inclusion. His thinking about how proportionate regulation can extend formal financial services to underserved populations without exposing them to predatory practices is essential reading for anyone working on the enabling environment for microfinance.

9. Alok Misra

MFIN (Microfinance Industry Network), India

As CEO and Director of MFIN, the Self-Regulatory Organisation and industry body for non-bank microfinance in India, Alok Misra is one of the most consequential figures in the world's largest microfinance market. India's microfinance sector has gone through extraordinary growth, significant crisis, and painstaking reform over the past two decades, and MFIN has been central to efforts to bring responsible lending standards and consumer protection frameworks to an industry that at its low point in 2010 contributed to tragic outcomes for over-indebted borrowers in Andhra Pradesh.

Misra's LinkedIn activity is consistent and substantive, offering analysis of India's microfinance sector, regulatory developments from the Reserve Bank of India, and broader financial inclusion themes. His annual publication Micro Matters: Macro View is one of the most comprehensive assessments of the Indian microfinance landscape produced each year. For anyone seeking to understand how microfinance works at the scale of tens of millions of borrowers in a complex, rapidly evolving regulatory environment, Misra is an essential follow.

10. Daniel Rozas

European Microfinance Platform (e-MFP), Belgium

Daniel Rozas is Senior Microfinance Expert at the European Microfinance Platform, where he leads strategic projects, contributes to the annual European Microfinance Award programme, and serves as a member of the e-MFP Secretariat. Based in Brussels, his work on client protection, market saturation, and crisis management has shaped how investors, regulators, and practitioners assess risk in major microfinance markets. He is co-founder of the MIMOSA project, which provides one of the most cited methodologies for assessing market saturation and overindebtedness risk in leading microfinance countries.

Rozas brings to the responsible finance agenda a distinctive background as a former Fannie Mae analyst during the 2001 to 2008 US mortgage boom, an experience he has openly described as shaping his caution about credit-driven growth in any market. His blog posts and CGAP commentary have repeatedly drawn the sector's attention to overheating risks in countries like Cambodia, often well before mainstream observers acknowledged the problem. For anyone wanting to understand how the field is thinking about client protection and market risk in 2025 and 2026, Rozas is one of the most consequential voices.

Category 3: The Researchers

Academics and analysts who produced the evidence base. These thought leaders have done the most rigorous work on the fundamental question of what microfinance actually does for poor households. Their findings are not always comfortable for advocates, but they have made the sector smarter about what works and why.

11. Jonathan Morduch

New York University Wagner Graduate School of Public Service, USA

Jonathan Morduch is one of the most cited microfinance researchers in the world and a co-author of books that have fundamentally shifted how practitioners and policymakers understand what microfinance does and does not do for poor households. His foundational 1999 paper "The Microfinance Promise" helped establish the academic framework through which the field understood its own impact claims, and his subsequent work challenged those claims with rigorous empirical scrutiny.

The book The Financial Diaries: How American Families Cope in a World of Uncertainty, co-authored with Rachel Schneider and published by Princeton University Press in 2017, used a year-long financial diary methodology to document how households actually manage money in conditions of income volatility and insecurity. While focused on American families, the methodology and findings resonated globally with practitioners who had long suspected that poor households' relationship with financial services was more complex than the standard microloan narrative acknowledged. His ongoing research at NYU's Financial Access Initiative continues to shape global debates about what financial inclusion actually achieves.

12. David Roodman

Independent consultant (formerly Coefficient Giving / GiveWell), USA

David Roodman wrote Due Diligence: An Impertinent Inquiry into Microfinance in 2012, and it remains the most honest book-length assessment of microfinance's impact ever published. Roodman, a former senior fellow at the Center for Global Development before holding roles at Open Philanthropy and Coefficient Giving and now working as an independent researcher, spent years synthesising the empirical evidence and concluded, among other things, that the case for microfinance as a poverty alleviation tool was substantially weaker than the field's promoters had claimed.

His conclusion was not that microfinance is bad but that it is complex: useful for managing income volatility and financial smoothing, but not reliably effective at building wealth or lifting borrowers out of poverty. That nuanced finding put him at odds with microfinance advocates at the time of the book's publication and was initially controversial. By 2026 it has become the mainstream view. David Roodman was right before the field was ready to hear it, which is one reasonable definition of a genuinely important thought leader.

13. Dean Karlan

Northwestern University / Innovations for Poverty Action, USA

Dean Karlan co-founded Innovations for Poverty Action (IPA) and has been one of the driving forces behind the application of randomised controlled trials to development interventions including microfinance. He served as USAID Chief Economist from 2022 to 2025 before returning to academic and IPA leadership work, and is now a professor at Northwestern University's Kellogg School of Management. His research has produced some of the most important evidence on what credit, savings, and insurance products actually do for low-income households, including a 2011 paper co-authored with Jonathan Zinman published in Science that found access to microcredit in the Philippines produced modest consumption improvements but did not generate the business creation and income growth that advocates predicted.

Karlan's book More Than Good Intentions: How a New Economics Is Helping to Solve Global Poverty, co-authored with Jacob Appel and published in 2011, explains the randomised controlled trial approach to a general audience and has been widely read by practitioners and funders seeking to understand which interventions to invest in. His ongoing work at IPA continues to produce evidence that challenges easy narratives about what microfinance can and cannot do.

14. Isabelle Guerin

Institut de Recherche pour le Developpement (IRD) / CESSMA, France

Isabelle Guerin is one of Europe's most important microfinance researchers, bringing a distinctive anthropological and feminist lens to the study of how financial services actually function in the daily lives of poor women. Based at the Institut de Recherche pour le Developpement in France, her fieldwork in South India, Senegal, and Mexico has produced findings about debt dynamics, gender relations, and social norms that purely economic approaches systematically miss.

Her book The Crises of Microcredit, co-edited with Marc Labie and Jean-Michel Servet and published by Zed Books in 2015, is one of the most rigorous critical assessments of microfinance's relationship to global financial capitalism and its periodic episodes of overindebtedness. Guerin's work is essential for anyone who wants to understand why the same microloan product can empower women in some contexts and deepen their vulnerability in others, and why the answer has as much to do with local gender dynamics and social norms as it does with loan size or interest rate.

15. Marek Hudon

Centre for European Research in Microfinance (CERMi), Universite Libre de Bruxelles, Belgium

Marek Hudon is co-director of the Centre for European Research in Microfinance at the Universite Libre de Bruxelles and has been one of the most productive researchers on the ethics and governance of microfinance institutions. His work on fair interest rates, the social mission of MFIs, and the governance structures that determine whether microfinance institutions maintain their social purpose or drift toward commercial objectives has shaped regulatory thinking in Europe and beyond.

His chapter in the landmark Handbook of Microfinance, Financial Inclusion and Development on the theory of fair interest rates on microcredit represents one of the most rigorous attempts to answer a question that microfinance's critics have always asked: how much is too much to charge poor borrowers? His ongoing research at CERMi examines how microfinance institutions maintain mission alignment over time, a question that has only become more pressing as commercialisation has accelerated across the sector.

16. Christabell Makokha

Bill & Melinda Gates Foundation, Ethiopia/Nigeria

Christabell Makokha is Deputy Director, Strategy at the Bill & Melinda Gates Foundation, where she oversees strategy, financial planning, and impact measurement for the foundation's Ethiopia and Nigeria programs from her base in Addis Ababa. With more than a decade of experience across organisations including CARE International, Mercy Corps AgriFin, IDEO.org, and Dalberg Advisors, her work has consistently focused on inclusive development strategies that reach underserved populations, particularly women, youth, and rural communities.

Her contribution to the financial inclusion field comes through her work on the design and implementation of inclusive development strategies in East and West Africa, including prior leadership of Mercy Corps AgriFin's Zambia country operations and global strategy. She serves on the board of Legado and the advisory board of Oxfam's aGILE innovation lab. Her engagement in 2025 and 2026 connects directly to the digital financial services and women's financial inclusion debates that have become central to the East African development conversation.

Category 4: The Policy Advocates

Leaders working at the intersection of microfinance and regulatory and policy environments. The design of the enabling environment for microfinance, including central bank regulations, financial consumer protection frameworks, digital finance oversight, and international development finance architecture, determines whether microfinance reaches underserved populations or serves the already-served.

17. Leora Klapper

World Bank Development Research Group, USA

Leora Klapper is the Lead Economist at the World Bank's Development Research Group and the principal architect of the Global Findex database, the world's most comprehensive dataset on how adults around the world access and use financial services. The Global Findex, published every three years, has become the global benchmark against which progress on financial inclusion is measured by governments, development organisations, donors, and MFIs.

The 2025 Findex, on which Klapper's team worked closely with Women's World Banking CEO Mary Ellen Iskenderian, showed that 77 percent of women globally now hold a financial account but that a persistent gender gap remains in low- and middle-income countries. Klapper's work on digital financial inclusion and development synthesises the evidence on what account ownership actually means for household welfare, moving the conversation beyond access toward usage and impact.

18. Timothy Ogden

Financial Access Initiative, NYU, USA

Timothy Ogden directs the Financial Access Initiative at New York University, a research centre that produces and synthesises evidence on financial services for low-income households globally. He is a regular contributor to sector publications and the author of The Case for Social Investment in Microcredit, published by the Financial Access Initiative, which made the argument for smart subsidy in a field that had overcorrected toward pure commercial models.

Ogden's work is defined by an insistence that evidence should drive practice, and by a willingness to acknowledge that the microfinance sector has not always followed its own research. His writing on the gap between what the evidence says and what practitioners believe is among the most useful material available for anyone trying to understand the microfinance evidence base honestly.

19. Greg Chen

BRAC International, USA

Greg Chen is Managing Director at BRAC International, the global arm of one of the world's largest and most respected NGOs, where his work focuses on financial inclusion, ultra-poor graduation programmes, and the institutional infrastructure that enables financial services to reach the poorest populations. Before joining BRAC International in late 2021, Chen spent more than 15 years at CGAP, where he became one of the most consistent voices for prioritising client welfare alongside institutional sustainability in financial inclusion debates.

Chen's writing during his CGAP tenure, particularly on digital credit risks and the potential for fintech-enabled lending to replicate the over-indebtedness problems of traditional microfinance, has continued to shape sector thinking. His current work at BRAC International focuses on how financial inclusion connects to broader poverty reduction strategies for ultra-poor households, building on BRAC's decades of evidence that pure credit access is rarely sufficient to lift the poorest families out of extreme poverty.

20. Greta Bull

Bill & Melinda Gates Foundation, USA

Greta Bull leads the Women's Economic Empowerment work at the Bill & Melinda Gates Foundation and is the lead author of the 2024 white paper Women and Equitable Growth in a Resource-Constrained World, published as part of the Gates Foundation's work on financial systems reform. The paper represented a significant shift in thinking within the development finance sector, making the case for reforming the international development architecture to build inclusive credit ecosystems specifically designed to serve women.

Bull previously served as CEO of CGAP for six years, during which she positioned the institution at the forefront of digital financial services and data-driven approaches to financial inclusion. Her influence spans both the institutional architecture of the sector and its intellectual direction, and her current work at the Gates Foundation gives her access to the funding and convening power needed to translate ideas into policy at global scale.

21. David Porteous

BFA Global, USA/South Africa

David Porteous founded BFA Global, formerly known as Bankable Frontier Associates, and has been one of the most important strategic thinkers on the enabling conditions for financial inclusion for more than two decades. His work has informed financial sector strategies, digital finance regulations, and consumer protection frameworks in dozens of countries across Africa, Asia, and Latin America. He has been a trusted advisor to governments, development finance institutions, and foundations seeking to understand how markets and regulations can be shaped to serve poor clients.

Porteous's concept of access frontiers, the idea that financial service providers need to understand the dynamics of moving from early adopter populations toward serving the poorest and most marginalised communities, has become a standard analytical tool in the financial inclusion policy toolkit. His current work at BFA Global on financial health measurement and on the potential and risks of AI in financial services represents the forward edge of the policy conversation.

Category 5: The Digital Innovators

Leaders making microfinance work in the mobile and digital age. Mobile money has been the most transformative development in financial inclusion of the past two decades, and a new generation of fintech companies is extending access to populations that traditional MFIs cannot reach cost-effectively. The voices in this category are shaping what financial inclusion looks like after the branch-based microloan model.

22. Tilman Ehrbeck

Flourish Ventures, USA

Tilman Ehrbeck is a co-founder and Managing Partner at Flourish Ventures, one of the leading impact investment funds focused on financial health and financial inclusion globally. Before Flourish, he served as CEO of CGAP and as a partner at Omidyar Network's Financial Inclusion initiative, giving him an unusually deep understanding of how patient capital and policy advocacy interact with the development of inclusive financial markets.

Ehrbeck's distinctive contribution is his focus on the investor ecosystem around financial inclusion: how capital can be deployed to back the organisations, both MFIs and fintech companies, that are genuinely advancing access for underserved populations rather than serving the bankable near-poor who are easier and more profitable to reach. His LinkedIn posts offer a consistent, evidence-grounded perspective on where impact investment in financial inclusion is actually heading in 2025 and 2026.

23. Arjuna Costa

Flourish Ventures, USA

Arjuna Costa is a co-founder and Managing Partner at Flourish Ventures and one of the most active voices in impact investment focused on financial health for underserved populations. His background spans time at the Omidyar Network, where he developed the financial inclusion investment thesis that later shaped Flourish's strategy, and direct work with fintech companies in emerging markets.

Costa's writing on the evolution of financial inclusion from a loan-access paradigm to a financial health framework has been influential with both investors and practitioners. His analysis of how digital financial services can deepen inequality as easily as they can reduce it, and what product design and consumer protection safeguards are needed to prevent that outcome, represents the kind of honest, evidence-driven thinking that distinguishes the best voices in this space from those who are simply promoting their portfolio.

24. Ashley Olson Onyango

GSMA, Kenya/global

Ashley Olson Onyango is Head of Financial Inclusion and AgriTech at the GSMA, where she leads the Mobile Money programme that produces the definitive annual State of the Industry Report on Mobile Money. Based in Nairobi, she oversees the GSMA's work supporting members and industry stakeholders across the roughly 150 countries where mobile money is operational, with a particular focus on extending mobile financial services to women, smallholder farmers, and other underserved populations.

The State of the Industry Report on Mobile Money 2025, produced under her leadership, documented that mobile money processed more than two trillion dollars in transactions in 2025 across 2.3 billion registered accounts, and a landmark Science paper by Suri and Jack found that M-Pesa lifted approximately 194,000 Kenyan households out of extreme poverty. Olson Onyango's work spans the data infrastructure of the mobile money industry, the regulatory and interoperability debates shaping digital public infrastructure, and the specific gender dynamics that determine whether women benefit equally from these systems. Her perspective from East Africa, the global epicentre of mobile money innovation, makes her one of the most credible voices on the future of digital financial inclusion.

25. Amee Parbhoo

Accion Ventures, USA

Amee Parbhoo is Managing Partner at Accion Ventures, the early-stage fintech investment arm of Accion International that rebranded from Accion Venture Lab in September 2025. She co-leads the $61.6 million Accion Venture Lab Fund II, which has invested in companies including Tala, Branch, Konfio, Pula, and Apollo Agriculture across more than 35 countries in Latin America, Africa, South Asia, Southeast Asia, and the United States.

Parbhoo brings nearly a decade of inclusive fintech investing experience built on prior microfinance and financial inclusion operating experience, giving her a practitioner-investor view of where digital financial inclusion is actually working and where it is not. She has been named to LAVCA's Top Women Investors in Latin America for three consecutive years from 2023 to 2025. Her public writing focuses on the hybrid models of technology and human interaction that build trust with underbanked populations, and on the case for sustainable growth metrics over aggressive expansion when serving financially fragile customers.

26. Corinne Riquet

CGAP, West Africa/Francophone Africa

Corinne Riquet is the CGAP Regional Representative for West and Central Africa Francophone, working from her base in Cote d'Ivoire to lead the institution's research and engagement across the region. Her work on mobile money adoption, digital credit, and financial behaviour in Francophone Africa fills a genuine gap in a literature that often focuses disproportionately on Anglophone East Africa and South Asia.

Riquet's research on how women in rural Francophone Africa navigate digital financial products, and the structural barriers that prevent them from capturing the same benefits that male users do, has been instrumental in shaping product design and digital literacy programming in the region. Her combination of quantitative rigour and deep contextual knowledge makes her one of the most credible voices on the intersection of digital finance and gender equity in one of the world's fastest-growing mobile money regions.

Category 6: The Women's Economic Empowerment Voices

Leaders specifically focused on making finance work for women. Microfinance has always been disproportionately focused on women as clients, but the field has not always been equally focused on whether those women are made genuinely better off. The voices in this category have pushed the sector to ask harder questions about women's economic agency rather than just their loan repayment rates.

27. Carmen Correa

Pro Mujer, Latin America

Carmen Correa has served as CEO of Pro Mujer since 2022, leading one of Latin America's most established women-focused social enterprises through a period of significant expansion across Argentina, Bolivia, Mexico, Nicaragua, Peru, and Guatemala. Pro Mujer has worked with more than two million women across the region over its 35-year history, providing financial inclusion, health services, digital skills training, and entrepreneurial support designed specifically to advance women's economic empowerment.

Correa was named to the Forbes 50 Over 50 list in 2025, alongside Mexican President Claudia Sheinbaum and other prominent Latin American women, in recognition of her leadership at Pro Mujer. Under her direction, the organisation has issued multiple gender bonds in Argentina, expanded into the Missing Middle of women-led small businesses too large for microfinance but too small for commercial bank funding, and built a regional platform for gender lens investing through the annual GLI Forum Latam. Her work demonstrates how a women-focused organisation can hold its founding mission while evolving beyond pure microcredit into a comprehensive economic empowerment offering.

28. Isabelle Barres

CGAP / BRAC International, global

Isabelle Barres spent more than a decade as the Director of the Smart Campaign, the global initiative that established client protection standards for the microfinance industry, before transitioning to broader work on responsible inclusive finance. The Smart Campaign's client protection certification programme, which Barres shepherded through multiple iterations, was adopted by MFIs serving hundreds of millions of clients and became the basis for the Cerise+SPTF social performance management standards that now govern how the sector measures its own accountability.

Barres' work operates at the structural level: building the systems through which responsible finance principles become auditable practice rather than marketing language. Her co-founding role at MIX, which built the comparative data infrastructure for the microfinance industry, and her current work continuing the responsible inclusive finance agenda at CGAP and BRAC International, make her one of the people most responsible for the practical infrastructure of responsible microfinance that currently exists.

29. Bobbi Gray

Grameen Foundation, USA/global

Bobbi Gray is Senior Research Director and AVP, Programs at Grameen Foundation, where her work focuses on the practical intersection of microfinance, social protection, and women's economic empowerment in the Global South. Her research has produced detailed evidence on how microfinance programmes interact with savings behaviour, nutrition, health, and social capital, providing a more holistic picture of how financial access fits within the broader set of changes that move households out of poverty.

Gray's application of financial diary methodology to understand how Grameen America clients' financial lives change over the course of their participation in group-based microlending programmes has produced granular evidence that goes well beyond standard impact metrics. Her work is particularly valuable for practitioners designing programmes that aspire to outcomes beyond simple loan repayment.

30. Wameek Noor

Digital Impact Alliance (DIAL), USA

Wameek Noor is Director of Insights at the Digital Impact Alliance, a global think-and-do tank focused on accelerating inclusive digital transformation in low- and middle-income countries. Her work focuses on how digital financial services and broader digital public infrastructure are evolving to serve underserved populations, with a particular focus on the gender dimensions of digital inclusion. Before joining DIAL she spent her career at CGAP, where she built deep expertise on the practical barriers that prevent women from benefiting equally from digital financial services: the digital literacy gap, the gender divide in mobile phone ownership, and the social norms that shape how women engage with financial institutions.

Noor's LinkedIn posts engage substantively with the financial inclusion practitioner community, offering analysis that connects institutional data to ground-level realities. Her work on how financial institutions and governments can design digital products that genuinely work for women, rather than simply extending existing products to a female customer segment, is among the most practically oriented work on digital inclusion and gender currently being produced.

Category 7: The Emerging and Critical Voices

Mid-career researchers, regional specialists, and critics building the next chapter of microfinance thinking. The field's most important new thinking often comes from practitioners and researchers who are close enough to the evidence to see what the previous generation missed, and honest enough to say so.

31. Sanjay Sinha

MicroCredit Ratings International (M-CRIL), India

Sanjay Sinha co-founded MicroCredit Ratings International with Frances Sinha in 1998, creating the first specialised microfinance rating agency and helping build the transparency and accountability infrastructure that the sector needed as it scaled. M-CRIL has since rated hundreds of microfinance institutions across South Asia, Southeast Asia, and Africa, producing comparative data on social performance, governance, and financial sustainability that has been essential for investors and regulators seeking to understand the sector.

Sinha's writing and research engage directly with the tensions between financial sustainability and social mission in Indian and South Asian microfinance, and he has been a consistent critic of practices that prioritise loan portfolio growth at the expense of client welfare. His perspective from within the South Asian microfinance ecosystem, which remains the world's largest by borrower numbers, gives him a grounding that purely academic or Washington-based voices cannot replicate.

32. Antonique Koning

CGAP, Belgium/global

Antonique Koning leads CGAP's work on Women's Economic Empowerment through financial inclusion and chairs the Technical Advisory Committee of FinEquity, the global community of practice convened by CGAP on women's financial inclusion. Based in Belgium and with over 25 years of inclusive finance experience including hands-on microcredit work in El Salvador, she has positioned CGAP as one of the most important institutional voices on the gender dimensions of financial inclusion.

Her March 2025 CGAP Working Paper, co-authored with Joanna Ledgerwood and Jenny Morgan, introduces a menu of 19 indicators for measuring Women's Economic Empowerment outcomes from financial inclusion interventions, providing the most rigorous practical framework currently available for funders, financial service providers, and policymakers seeking to assess whether their work is actually moving the needle for women. Her ongoing work on gender norms, customer outcomes, and consumer protection regulation makes her one of the most important emerging voices on how financial inclusion translates into measurable improvements in women's lives.

33. Valentina Hartarska

Auburn University, USA

Valentina Hartarska is one of the leading agricultural and rural microfinance researchers in the United States and a co-editor of the Handbook of Microfinance, Financial Inclusion and Development with Robert Cull, published by Edward Elgar in 2023. Her research focuses on the performance, governance, and social impact of microfinance institutions, with a particular emphasis on how rural financial institutions serve smallholder farmers and agricultural communities.

Her work on the governance structures of cooperative and mutual microfinance institutions has contributed to understanding why ownership structure matters for client welfare, and her research on agricultural microfinance in developing countries has informed both practitioner decisions and policy design. Hartarska's grounding in economics and agricultural science gives her a practical orientation that connects well with the development practitioner community.

34. Laura Foschi

ADA Microfinance, Luxembourg

Laura Foschi is Executive Director of ADA (Appui au developpement autonome), the Luxembourg-based NGO that has been one of the most consistent funders and knowledge partners for microfinance institutions across the Francophone world and beyond. With 25 years of inclusive finance experience including over a decade of fieldwork in Latin America, Africa, and the Balkans, she leads ADA's technical assistance, applied research, and direct financing for MFIs across Africa, Central America, and Southeast Asia.

Foschi sits on the boards of the Social Performance Task Force Europe and the Financial Innovation Tool, lectures on inclusive finance at the University of Luxembourg and the Universite Libre de Bruxelles, and contributes through ADA to the European Microfinance Platform's annual Financial Inclusion Compass survey. Her engagement with the responsible finance agenda, the digital transformation of microfinance, and the governance challenges that determine whether MFIs maintain social purpose under commercial pressure makes her one of the most consistently substantive European voices in the sector.

35. Sabine Mensah

AfricaNenda Foundation, Kenya/global

Sabine Mensah is Deputy Chief Executive Officer of the AfricaNenda Foundation, the pan-African digital payments initiative working to accelerate the development of interoperable payment infrastructure across the continent. Based in Kenya, her work sits at the newest and most rapidly evolving frontier of financial inclusion: the shift from microfinance as small loans delivered through branch networks toward financial inclusion as digital payment infrastructure that enables the entire ecosystem of financial services to reach underserved populations.

Mensah brings to this work a deep understanding of how African payment ecosystems are developing, the regulatory and interoperability challenges that determine whether digital payment infrastructure serves the whole population or primarily the already-served, and the specific gender dynamics that shape women's access to and benefit from digital financial services. Her voice represents the direction in which microfinance and financial inclusion are heading, and following her work gives practitioners and investors a clear view of the frontier.

Notable Voices We Almost Included

Any honest list of microfinance thought leaders must acknowledge the foundational figures it chose not to include. Ela Bhatt, who founded the Self Employed Women's Association (SEWA) in India in 1972 and pioneered savings-led financial services for informal-sector women workers long before the term microfinance was coined, built one of the most enduring and impactful institutions in the history of inclusive finance. Her work predates Grameen Bank and in many ways anticipates the sector's evolution from credit-centred to savings-centred approaches. She is not included in the numbered list because her current digital presence is limited, not because her contribution is anything less than extraordinary.

Jessica Jackley, co-founder of Kiva and author of Clay Water Brick: Finding Inspiration from Entrepreneurs Who Use Ingenuity to Overcome Poverty, brought microlending to a mass consumer audience through the peer-to-peer lending platform she helped build. Her contribution to popularising microfinance well beyond specialist communities is significant. She was considered seriously for inclusion and was ultimately displaced by the requirement to include voices more directly engaged in practitioner and research conversations in 2025 and 2026.

Several senior figures at CGAP, the World Bank, and the Gates Foundation who could not be separated easily into individual entries also deserve acknowledgement: the institution-building work of leaders at these organisations shapes the field's intellectual architecture in ways that go far beyond any single person's output. Brene Brown, Adam Grant, Simon Sinek, Patrick Lencioni, Daniel Pink, Malcolm Gladwell, and Susan Cain would appear on most leadership-adjacent lists. Their work has shaped adjacent fields and the list deliberately moved past these household names to surface fresher voices whose focus is specifically microfinance and financial inclusion.

Common Mistakes When Engaging with Microfinance Thought Leadership

The single most common mistake practitioners and funders make when engaging with microfinance thought leadership is treating advocacy and evidence as interchangeable. The field has a long history of using individual success stories and emotionally compelling narratives to represent what is actually a highly variable intervention. Roshaneh Zafar's achievement in building Kashf Foundation into a transformative institution for women in Pakistan does not mean that every microfinance institution, in every context, produces equivalent outcomes. Following the evidence-based voices on this list, particularly the researchers and critics, provides the intellectual ballast needed to avoid this conflation.

A second mistake is assuming that digital microfinance automatically represents progress. The mobile money revolution has been genuinely transformative in contexts like Kenya and Tanzania, where mobile money accounts enabled millions of households to access financial services for the first time and, as documented in peer-reviewed research, lifted households out of poverty. But digital credit products have also replicated the worst features of traditional over-indebtedness in new forms, with faster lending cycles and algorithmic credit scoring that can intensify rather than reduce vulnerability. The digital innovators on this list are candid about both dimensions.

A third mistake is treating microfinance as purely a developing-country phenomenon. The BBVA Microfinance Foundation, ADA Microfinance, and the European Microfinance Platform demonstrate that microfinance in Europe plays a significant role in supporting migrant entrepreneurship, financial inclusion for unemployed people starting small businesses, and rural economic development in regions that traditional banks do not serve well. The Adie model in France, which has supported tens of thousands of entrepreneurs since 1989, represents a tradition of European microfinance that deserves more attention from practitioners focused on the Global South.

A fourth mistake is failing to engage seriously with the critics. David Roodman's Due Diligence, Dean Karlan's RCT findings, and Isabelle Guerin's anthropological research on debt dynamics are not comfortable reads for microfinance advocates. But the practitioners who engage seriously with this literature are better equipped to design interventions that actually work than those who dismiss critical evidence as hostile.

A final mistake is following only the loudest institutional voices. Some of the most important thinking in microfinance is produced by mid-career researchers, regional specialists, and country-level practitioners whose names do not appear in global media. The list above deliberately includes voices like Corinne Riquet, Wameek Noor, and Antonique Koning precisely because their work represents the leading edge of what the field knows, not what it knew ten years ago.

Implementation Guide: Building Your Microfinance Knowledge Practice

The most effective way to engage with the thought leaders on this list is to treat their work as a structured curriculum rather than a social media feed. Start with the foundational texts: Alex Counts' Small Loans, Big Dreams gives you the origin story. David Roodman's Due Diligence gives you the honest assessment of what the evidence actually says. Mary Ellen Iskenderian's There's Nothing Micro About a Billion Women gives you the contemporary argument for where the sector needs to go.

Follow the sector's knowledge platforms. FinDev Gateway, operated by CGAP, is the most comprehensive freely available resource on microfinance and financial inclusion, with thousands of papers, case studies, and policy documents and regular blog posts from practitioners. The Center for Financial Inclusion's blog, the CGAP blog, and the e-MFP blog all publish regular analysis from the thought leaders on this list and from the networks surrounding them.

For LinkedIn engagement, prioritise the practitioners and researchers who post regularly and engage in comments: Graham Wright, Alok Misra, Tilman Ehrbeck, Arjuna Costa, Amee Parbhoo, Daniel Rozas, and Sabine Mensah are among the most consistently valuable follows in the sector. They post substantive analysis, share new research, and engage in genuine debate with other practitioners.

Attend the European Microfinance Week in Luxembourg each November, the Global Inclusive FinTech Forum, and the regional events run by the Alliance for Financial Inclusion. These convenings bring together practitioners, researchers, policymakers, and investors in ways that are genuinely difficult to replicate through digital means alone.

Give yourself a 90-day curriculum: in the first month, read the foundational texts and follow the researchers (Morduch, Roodman, Karlan). In the second month, follow the practitioners and engage with their operational writing. In the third month, engage with the digital innovators and the policy advocates. By the end of that period, your mental model of how microfinance actually works will be substantially more nuanced than when you started. That nuance is the point.

Frequently Asked Questions

Who are the most important microfinance thought leaders globally?

The most influential thought leaders span several different traditions. The pioneers who built the field include Muhammad Yunus, whose Grameen Bank model inspired institutions in more than 100 countries, and Alex Counts, who brought the Grameen approach to international scale through the Grameen Foundation. The researchers who have most shaped the evidence base include Jonathan Morduch, David Roodman, and Dean Karlan. The practitioners who have built institutions at scale with genuine social mission include Roshaneh Zafar, Andrée Simon, and Mary Ellen Iskenderian. Digital innovators like Ashley Olson Onyango and Arjuna Costa are shaping what financial inclusion looks like in the mobile era.

What is the difference between microfinance and microcredit?

Microcredit refers specifically to small loans provided to borrowers who lack access to traditional banking services. Microfinance is a broader term that encompasses not just small loans but also microsavings, microinsurance, money transfer services, and other financial products designed for low-income populations. The field has progressively shifted from a credit-centric model toward a more comprehensive microfinance approach, reflecting growing evidence that savings and insurance are at least as important as credit for building household financial resilience.

Does microfinance actually work to reduce poverty?

The honest answer, shaped by decades of rigorous research including multiple randomised controlled trials, is that microfinance has complex and variable effects. It is generally effective at helping households manage income volatility, smooth consumption, and build small amounts of savings. The evidence for its ability to generate significant business growth or lift households permanently out of poverty is much weaker than early advocates claimed. Context matters enormously: the same product design that empowers women in one community can deepen their vulnerability in another. David Roodman's Due Diligence and Dean Karlan's research provide the most honest synthesis of the evidence.

How is digital technology changing microfinance?

Mobile money has been the most transformative development in financial inclusion of the past two decades. A landmark study published in Science by Suri and Jack found that M-Pesa's expansion in Kenya lifted approximately 194,000 households out of extreme poverty by enabling poor households to receive remittances and smooth income shocks in ways previously impossible. New fintech companies including Tala, Branch, and Jumo are using smartphone data for alternative credit scoring, providing microloans to populations without traditional credit histories. The risks are also real: digital credit has replicated over-indebtedness dynamics in some markets, and without careful consumer protection, the speed and scale of digital lending can cause harm.

How was this list compiled?

The 35 thought leaders on this list were selected on the basis of genuine contribution to how the global microfinance field thinks and operates. The criteria included original research, writing, or institutional work that has shaped the sector's evidence base, practice standards, or policy frameworks; geographic and disciplinary diversity; and active engagement in sector conversations in 2025 and 2026. The list deliberately includes both champions and critics of microfinance, and both institutional voices and those working outside the major international organisations. No single geography represents more than 30 percent of the list.

What are the best resources for staying current in microfinance?

FinDev Gateway (findevgateway.org) is the most comprehensive freely available knowledge platform for the sector. CGAP's blog and research briefs provide regular evidence-based analysis. The European Microfinance Platform's Financial Inclusion Compass offers an annual survey of practitioner sentiment. The 60 Decibels Microfinance Index provides the most rigorous annual assessment of how microfinance clients themselves evaluate their experience. For academic research, the Journal of Development Economics and World Development publish the most cited microfinance research.

Final Thoughts

Microfinance is 50 years old, and it has spent most of those years oscillating between uncritical celebration and harsh dismissal. The truth, as the best thought leaders on this list have consistently argued, is far more interesting than either extreme. It is a field that has genuinely transformed access to financial services for hundreds of millions of people, that has also caused real harm in contexts where commercial incentives outpaced client welfare considerations, and that is being remade by digital technology in ways that simultaneously expand access and create new risks.

The 35 people on this list have spent their careers working through that complexity. Following their work does not give you simple answers. It gives you better questions: not "does microfinance work" but "under what conditions, for which populations, with which product designs and consumer protections, does financial inclusion actually improve people's lives?" Those are the questions the sector is still working to answer, and the people on this list are doing the most consequential work on them.
