In this episode, a16z GP Angela Strange hosts Tim Mayopoulos (ex-CEO of Fannie Mae and ex-president of Blend), Mike Yu (co-founder and CEO of Vesta), and Andrew Wang (co-founder and CEO of Valon) to unpack why standardization and regulation slow change, and how modern loan-origination and servicing platforms, cleaner data, and AI can cut costs, boost transparency, and reduce errors. They also discuss policy levers that could speed innovation and what a true one-tap mortgage could look like.

Mark also explains how AI is pushing media from “social” to algorithmic, why he expects millions of models, and why ESOPs are an underrated wealth engine. He shares what he’d build today and weighs in on NBA economics under the new collective bargaining agreement.
