Cat Wu, who led product for Claude Code and Cowork, has left Anthropic, per four sources. No reason or next step is stated; Anthropic's reply is disputed.
Cat Wu, who led product for Claude Code and Cowork, has left Anthropic, according to four pages we read on November 4, 2026: 36Kr, The FIREwall, Analytics India Magazine and Emergent. We read all four through automatic summaries. This is neither legal nor investment advice.
The essentials
- The departure: last day Friday, October 30 (The FIREwall, Analytics India Magazine). Announced on X November 3 per two sources, November 4 per 36Kr.
- The role: head of Claude Code and Cowork products (36Kr).
- Disputed: whether Anthropic confirmed, and how many people left.
- Not established: the reason, the next step, the successor, any link with the IPO.
What is reported
36Kr, republishing 新智元, calls Cat Wu head of Claude Code & Cowork products; Analytics India Magazine describes Cowork as an Anthropic tool for tasks beyond software development. Per Analytics India Magazine, the message on X recalls asking Claude Code, two years ago, to build a reinforcement learning environment, and notes that today's default is to trust Claude's judgment to auto-approve permission requests. We did not read it; per that summary it gives no reason.
The other departures
Per The FIREwall and Analytics India Magazine, Thariq Shihipar announced a departure on October 24 after more than a year on Claude Code, wanting a break before a new project. Anthony Morris, who built its desktop app, had a last day of October 23 (The FIREwall) or announced on October 24 (Analytics India Magazine). The FIREwall says none of the three gave a reason or destination. 36Kr also names Sunil Shah, which no other page confirms. The count is three departures in about two weeks (The FIREwall, Analytics India Magazine) or a fourth in about 10 days (36Kr).

The IPO: context, not an established cause
Analytics India Magazine notes the amended S-1 filed on November 2 showed $16.96 billion in September-quarter revenue, covered in our article on Anthropic's amended S-1. 36Kr, The FIREwall and Emergent mention the IPO as a backdrop; no page we read links the departures to it. Such a link would be an author's framing, not a verified fact.
What is not established
The reason, the next step, the successor, the effect on Claude Code and Cowork, the exact number of departures. On Anthropic's response, sources disagree: Analytics India Magazine says it confirmed to Business Insider; Emergent says it made no public statement and named no replacement; 36Kr and The FIREwall include none. We read no Anthropic statement directly.
