I’m launching a podcast and the first episode is out.

Main Branch is a show about how leading AI startups actually get built, deployed, and scaled. Each episode I’ll go deep with AI founders and early adopters covering their tech stack, research bets, inflection points, key hires, and topics top of mind for me and the founders I talk to day-to-day.

For the first episode I sat down with Arvind Jain @jainarvind, founder and CEO of @glean. Arvind took an idea most people had written off, enterprise search, and built it into one of the fastest-growing AI platforms out there, past $300M in ARR. He is now on a mission to expand human potential to do extraordinary work.

We get into: • The early operating playbook, including sending 100 cold LinkedIn DMs a day • The product arc from a search box to an agentic coworker with enterprise context • Why he thinks the AI market is still 100x undersupplied, and why crowded markets shouldn't scare founders • His case for how to compete when the labs move up the stack • How AI has changed hiring (hint: you can't pass some of Glean's interviews without it)

More builders coming soon. Full episode below 👇
