In this episode of the Wharton Fintech Podcast, hosts Sabrina Fathi and Wesley Aster speak with Yoonkee Sull, General Partner at ICONIQ, about building category-defining fintech companies through every market cycle. Yoonkee reflects on his journey from early ICONIQ associate to GP, lessons from backing leaders like Chime, Groww, Adyen, Wealthsimple, and Ramp, and what it takes to earn trust with founders over the long term. They unpack how startups can differentiate in a crowded space, how embedded finance is reshaping distribution, and why knowing your customer better than anyone else is the ultimate moat. With thoughtful takes on unit economics, financial inclusion, and the real use cases for AI and blockchain, this conversation is a must-listen for founders, operators, and investors navigating the next chapter of fintech.
