Cat Wu, the product leader who steered Anthropic's Claude Code from a internal experiment to one of the most popular AI coding agents, is joining OpenAI as head of product management for core products. She announced the move on X on November 5, and OpenAI confirmed it to Business Insider; OpenAI president Greg Brockman publicly welcomed her.
At OpenAI, Wu will work with Nick Turley on enterprise products and Ashley Alexander on consumer products, reporting to executive Tibo Sottiaux, according to an OpenAI spokesperson.
Wu joined Anthropic in the summer of 2024 and spent about two years there. Alongside Claude Code creator Boris Cherny, she helped take the tool from an internal prototype to a research preview in February 2025 and then to a product that became a major growth driver for Anthropic. She also led product for Cowork, Anthropic's AI tool for non-coding work, and Tag.
Announcing her departure on November 3, Wu said her last day had been October 30 and traced the arc of the product: when she arrived, users had to approve most actions manually and the model mainly answered questions and wrote tests; today Claude executes large code migrations and ships new features. At OpenAI, she said, she wants to build agents that support people and teams while keeping users in control, noting that she respects OpenAI's user base of more than 1 billion.
The timing is awkward for Anthropic, which is preparing for an IPO late this month. Asked whether the prospect of selling shares influenced her exit, Wu said it did not. The move lands in the middle of an intensifying fight over coding agents, the most commercially proven AI product category: OpenAI is pushing Codex from developer tooling toward broader software work, while Claude Code remains Anthropic's flagship enterprise wedge.
For the labs, product leadership has become the scarce resource. Models are converging; the difference between an agent that engineers trust and one they abandon increasingly lives in product decisions. Wu's jump suggests OpenAI intends to compete on that front, not just on benchmarks.
