ICONIQ General Partner, Yoonkee Sull - Finding Edge in Fintech and Building Enduring Companies

ICONIQ's Yoonkee Sull on why fintech's moat is trust

Yoonkee Sull runs fintech investing at ICONIQ Growth, and his case for the sector rests on an asymmetry. Banks have distribution and balance sheets but weak products, so startups win on speed, transparency, price and user experience, and the trust that follows becomes a durable brand. Because distribution is the scarce input, he favours embedded finance and expects banks and fintechs to coexist. ICONIQ's own edge was temperament, buying market leaders through the 2022 pullback while peers stayed out.

Takeaways

• Banks lose on product, fintechs win on trust. Legacy financial institutions are weak on speed, cost, convenience, simplicity and interface, Sull says. Consistently delivering on those builds trust, which he calls the ultimate moat. Their real advantages are distribution and balance sheets, so startups must win with better products or creative distribution.
• Embedded finance closes the distribution gap. Vertical software businesses and marketplaces become distribution points for lending and other products, letting fintechs reach customers incumbents already own. Sull expects fintech-bank partnerships to persist and players to coexist, though more digital banks now pursue their own licences for cheaper capital.
• ICONIQ leaned in while peers pulled back. ICONIQ kept investing in fintech through the 2022 downturn, when many firms turned negative, because the secular trends held and market leaders kept gaining users and wallet share. The swing came from zero rates and stimulus, then rapid hikes. Activity returned in 2025, helped by AI.
• Growth counts only with sound unit economics. ICONIQ weighs founder and team, size of the problem, uniqueness of the solution, customer outcomes, retention and a path to market leadership. Growth correlates most with long-term value, but only alongside sound unit economics. Credit businesses may take first-year losses while building their underwriting engine.
• ICONIQ treats AI as enabling technology. ICONIQ treats AI and blockchain as enabling technologies rather than sectors. Sull sees AI in underwriting, risk and fraud, and in customer support. It also automates accounting and treasury work. A portfolio CEO scaled personalized messaging to millions of customers only through AI.
• Fee-free products widened access to finance. Sull cites Chime's fee-free checking, Monzo's transparency, Robinhood's commission-free trading and Altruist's tools for advisers. Many fintech businesses created value by removing hidden fees and letting people access products they otherwise could not have had.
