YC CEO's Claude Code setup: a virtual engineering team

Visit official site →

About

gstack is Garry Tan's (president and CEO of Y Combinator) open-sourced Claude Code configuration: 23 role-based slash commands that make the agent act as a CEO, designer, engineering manager, QA lead, security officer, and release engineer (/plan-ceo-review, /review, /qa, /ship, /cso, and more). It has roughly 136,000 GitHub stars under MIT. The famous productivity numbers attached to it are the author's own measurement methodology and were publicly debated, so treat them as one person's report, not a benchmark. It needs Claude Code plus Bun, and it is opinionated to one person's workflow, so expect to fork and adapt rather than adopt blindly.
