Brief

Kathryn Wu (post dated 2026-04-08 on X) launched GTMbrain, a forkable GTM system distilled from her and other YC founders' lessons to solve the common gap between advice and actionable process. GTMbrain is meant to be iterated in Codex or Claude Code like Gstack, and she asks the community to contribute PRs with improved workflows or concrete examples.

Everyone says “do GTM.”
Almost nobody gives you a great system.

So we built GTMbrain: a forkable GTM system based on lessons from me + other YC founders.

Run it in Codex or Claude Code to iterate with it just Iike Gstack.

And if you have better workflows or real examples, send a PR.
