Cat Wu, the product leader behind the success of Anthropic's Claude Code, has left the startup to join rival OpenAI to lead product management for its core products team. The move represents a significant talent poach for OpenAI weeks before Anthropic's planned initial public offering.
Wu announced on X that she had left Anthropic the previous week, thanking the Claude Code team and user base. She announced her move to OpenAI on Wednesday. OpenAI confirmed the hire, and Anthropic declined to comment.
Wu was the product leader for Claude Code, an AI coding tool that grew from an internal prototype into a major commercial product under her oversight, bolstering Anthropic's finances and transforming software engineers' day-to-day work. At OpenAI, she will lead product management for the core products team, reporting to Tibo Sottiaux and working with Nick Turley on enterprise products and Ashley Alexander on consumer products.
In her announcement post, Wu wrote that she has a lot of respect for OpenAI and cited its reach of over a billion users. She said at OpenAI "we'll build agents that have your back and your team's, and keep you in control, so you get more time for the people and work you love."
The hire could help boost adoption of OpenAI's Codex, a priority since the company fell behind Anthropic in enterprise sales earlier this year. AI models' coding abilities and their handling of long-term tasks are central to the industry's growing ambitions. The Information reported that Wu left Anthropic for AI coding startup Cursor in 2025 before quickly returning. She wrote on X that she had “no idea” if leaving would allow her to sell shares earlier than remaining employees and said it “wasn't a factor for me.”
