I sat down with David Haber, General Partner at Andreessen Horowitz, the venture firm managing ~$100 billion in AUM, at a16z's New York office. David has been building and investing in fintech since 2011 and thinks the first wave of fintech is one of the most thoughtful investors in the industry. We talk about firm over fund, building collective intelligence inside a firm, the Overton window on recording conversations, and why financial services may be the biggest opportunity for AI.

 I sat down with Cristina Junqueira, co-founder of Nubank and CEO of Nubank’s U.S. operation, one day after Nubank officially launched in the United States. Founded in 2013 in a house in São Paulo, Nubank now serves over 140 million customers, 64% of Brazil’s adult population, and they have just launched their US operations.
We talk about why product-led growth is a necessity rather than a strategy, why she would rather have a smaller customer base that loves the product than buy her way to growth, and why she spent launch night reading customer support transcripts.

I sat down with Maik Taro Wehmeyer, co-founder and CEO of Taktile, an agentic decision platform that helps financial services companies automate their highest-stakes decisions: credit underwriting, fraud detection, and compliance. Maik and his co-founder built the company from a failed first product and 99 rejected banks into a business that just closed a $110 million round led by Goldman Sachs.

I sat down with Harshil Mathur, Co-Founder and CEO of Razorpay, one of India’s most important fintech and tech companies. Razorpay moves hundreds of billions of dollars in annual payment volume and powers about 85% of the country’s largest tech companies. They are also reportedly preparing for a large IPO on the Indian Stock Exchange.
Harshil started coding at age 12 and began building Razorpay in 2014, only a year after graduating college. Their early days were not easy, and Harshil and his co-founder, Shashank Kumar, ran into about a hundred bank rejections before a single bank partner said yes. Fast forward to 2026, and the company today is one of India’s most important payments players.

Miguel Armaza flew to Almaty, Kazakhstan to sit down with Mikhail Lomtadze, CEO and Co-Founder of Kaspi, for their second conversation in two years. It is hard to explain how dominant and loved Kaspi is in this market: in a country of 20 million people, more than 15 million use the app daily, and it handles two thirds of Kazakhstan's e-commerce. What started as a traditional bank is now one of the world's most defining super apps, and it just entered a new chapter, expanding into Türkiye through Hepsiburada and launching Kasper, its consumer-facing AI assistant.
They discussed why Kaspi's final destination is the everyday AI assistant rather than the everyday super app, why almost nobody in the company carries a financial target, how a 10,000-person organization stays a collection of startups, what the first year inside Türkiye has actually taught them, and why he thinks investors are underestimating their ability to execute.
