I sat down with Michael Sindicich, President of Navan, the AI-powered travel, expense, and payments platform that works with 50 of the S&P 500. In 2020, one week after launching its payments product, Navan's revenue went to zero, and the board chose to go on offense. Five years later, Navan became the first company to go public during a U.S. government shutdown and watched its stock fall from $25 to about $8. We talk about the decision that defined the company, what it was like inside Navan when the stock was falling, and how a reconciliation headache turned a travel company into a fintech.

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.

 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 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.

I sat down with Victor Cardenas, Co-Founder and CEO of Slash, one of the fastest growing fintechs in America that went from $10M to $300M in annualized revenue in 24 months And just crossed a $1.4 billion valuation after a $100M Series C led by Ribbit Capital, Khosla Ventures and Goodwater Capital. The company powers over $30Bn in annualized payment volume across wires, ACH, stablecoin, and card for over 5,000 businesses. Victor is a Venezuelan immigrant, Stanford dropout, and Thiel Fellow. He started Slash at 19 serving sneaker resellers, lost 60% of his revenue almost overnight, and rebuilt the company into a rocketship by betting on vertical banking.
