Payments Are About People: Innovation from the Digital South

What does a journalist turned payments executive see that others miss? In this episode, Wolfgang Fengler sits down with Estelita Haas, Head of Market Intelligence and Product Marketing at Ebanx, a fast-growing Brazilian fintech unicorn now operating in 25+ countries across Latin America, Africa, and Asia.

Estelita shares how her background reporting from Brazil's overlooked regions shaped her conviction that the most important stories, and the most important markets, are the ones nobody is paying attention to. That same instinct drives Ebanx's focus on the "Digital South": hundreds of millions of mobile-first, young, middle-class consumers who are transacting online for the first time and can't be reached with a card-first checkout.

In this conversation, you'll hear about the innovation happening right now in emerging market payments, from Brazil's Pix reaching 95% adult adoption in under five years, to India's UPI embedding inside Rupay cards, to M-Pesa in Kenya issuing virtual cards for online purchases. Estelita argues that rather than competing, these payment methods are feeding each other and building a larger, more inclusive ecosystem.

Key themes: fintech innovation, emerging markets, financial inclusion, digital payments, the Global South, consumer behaviour, SaaS, gaming, social commerce.

Can data predict the next big consumer trend?

In this episode of Data Talks, Wolfgang Fengler speaks with Yarden Horwitz, Co-Founder of Spate, about the science of spotting trends before they go mainstream.

Drawing on her experience at Google and building one of the fastest-growing trend intelligence platforms, Yarden explains how brands can use search, social, and behavioral data to understand what consumers want next. From beauty and wellness trends to generational shifts and artificial intelligence, this conversation explores how data reveals emerging opportunities long before they appear in the headlines.

Yarden shares lessons from building a startup through Y Combinator, discusses why trends like press-on nails and longevity treatments have endured, and explains why the future of AI is not about replacing humans—but helping them tell better stories with data.

A fascinating discussion for anyone interested in consumer behavior, innovation, marketing, and the future of insights.

In this episode of Data Talks, World Data Lab CEO Wolfgang Fengler speaks with co-founder and global middle class expert Homi Kharas about new research that challenges one of the most widely discussed narratives in economics today.

Featured prominently in The Economist, World Data Lab’s latest analysis examines inequality through the lens of consumption rather than wealth. By comparing how much the bottom 50% of the global population consumes relative to the top 10%, the data reveals a surprising trend: global inequality in consumption is improving, largely driven by rapid economic growth in countries such as India, China, Indonesia, and across Southeast Asia.

Together, Wolfgang and Homi explore:

• Why consumption inequality may be a more meaningful measure of real living standards than wealth inequality
• How global economic growth is lifting billions of people out of extreme poverty
• Why the rise of emerging economies is reshaping the global distribution of prosperity
• The role of government policies, taxation, and public services in influencing inequality within countries
• And why, despite ongoing global uncertainty, the long-term trajectory for human welfare may be more positive than many assume.

The conversation offers a data-driven perspective on one of the defining debates of our time — and highlights how new global datasets can help policymakers, businesses, and researchers better understand the real progress happening across the world economy.

How Data Changed the Climate Conversation
Host: Wolfgang Fengler
Guest: Sir Andrew Steer KCMG, PhD

How did climate and nature move from the sidelines to the center of global economic decision-making—and what role did data play in that shift?

In this episode of Data Talks, Wolfgang Fengler speaks with Sir Andrew Steer KCMG, PhD—former President & CEO of the Bezos Earth Fund (2021–2025), former President & CEO of the World Resources Institute, and now Professor in Practice at the London School of Economics’ Global School of Sustainability.

Andrew reflects on key turning points in the evolution of environmental economics, including the rise of “natural capital” and the growing demand for evidence-based climate policy. The conversation explores today’s most important data innovations—from satellite and AI-enabled monitoring of forests and carbon stocks to the emerging ability to detect methane emissions from space—and why better measurement doesn’t automatically translate into better action.

They close with a powerful set of numbers about biodiversity loss and the future of development, and what it will take to turn climate data into durable progress.
