Cat Wu

Bio

Head of product for Claude Code and Co-work at Anthropic. Runs one of the fastest-shipping product orgs in the AI industry — timelines collapsed from quarter-long to week-long with the help of an "evergreen launch room" cadence and a heavy reliance on engineers shipping end-to-end. Vocal advocate for replacing PRDs with metrics readouts plus a written team-principles doc.
