garrytan · x · 2026-09-22
YC President Garry Tan demonstrated Capy executing an ambitious bug-fix wave on his GBrain project, with clear task delineation, automatic parallelization, and clean GitHub PRs and CI workflows.
He says Capy tracks multi-step workflows and lands large PRs faster than Codex or Claude Code on its own — his "favorite new agentic coding secret weapon" of the week. Capy orchestrates fleets of cloud coding agents inside Slack and existing tools, covering PR review, issue triage, code migration, refactors, and E2E testing via native computer and browser use, claiming 70,000+ engineer users.
