48: Henri Stern - Principled Enough to Be Pragmatic

Henri Stern (X, LinkedIn) is the co-founder and CEO of Privy. Privy builds wallet infrastructure for developers, enabling them to let their users hold and use crypto, including stablecoins. Privy was acquired by Stripe in 2025, and remain an independent organization within the company. They work with large fintechs like Ramp and Klarna while also supporting some of the most notable crypto-native platforms like Hyperliquid. Henri also supports a number of other crypto efforts within Stripe. Henri is thoughtful, measured, and principled. Yet he is also pragmatic. He doesn’t like to play philosopher and yet he is one of my favorite people ask big questions about our future and our digital lives. Our conversation is anchored in the phrase at the bottom of Privy's website: "technical decisions are moral decisions." He and Asta Li started Privy to focus on user data privacy, and we talk about what digital privacy means and why it still matters. After realizing they were trying to serve the market something it didn’t want, Privy found an inflection point initially by enabling developers to embed crypto wallets in their apps. We talk about the painful decision to pivot, and later, to commit to both ends of the crypto market: hardcore, trading-oriented products and stablecoins as they flooded into traditional fintech infrastructure. We also talk about joining Stripe, what Crypto’s future looks like, and his level-headed mindset for our tumultuous future.
