Ryan is the VP of Product at Mercury, my favorite fintech product. We covered three things that’s on every AI builder’s mind — how to build a Claude Code second brain, how to make your product agent-ready with APIs and MCPs, and what Mercury’s data reveals about OpenAI and Anthropic’s race for the enterprise.

Ryan and I talked about:

(00:00) Why APIs and MCPs are the primary interface

(04:40) How to get your product agent ready

(07:51) Will MCPs cannibalize your app DAU?

(10:36) How to decide between MCPs and CLIs

(13:10) Inside Ryan's Claude Code second brain

(18:40) Getting AI to coach you after every meeting

(20:46) Mercury data: Are startups switching to Anthropic?

(23:05) The product development process will never be the same
