About this episode

The $13T U.S. mortgage market serves 50M homeowners but still runs on decades-old software. 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.
