Cat Wu, Anthropic's head of product for Claude Code and one of the most visible public faces of the company's breakout coding tool, announced on Monday that she has left the AI startup. The departure, disclosed in a post on X on November 3, comes as Anthropic prepares for a hotly anticipated initial public offering, and removes one of the product leaders most associated with the company's rise in agentic software development.

Wu spent just over two years at Anthropic, joining in August 2024 as a product manager on the Research PM team — a group that connected researchers with real-world customers to improve models — before rising to lead product for Claude Code. Business Insider, which first reported the exit, described her as "one of the faces of Claude Code," a product that grew from an internal experiment into the tool many developers consider the defining application of the agentic coding era. For readers tracking the industry's leadership churn amid the IPO wave, AI Buzz Wire follows every move reshaping the AI business landscape.

From research PM to the product of the year

Wu's path to leading Claude Code product was unconventional. Before Anthropic, she worked as a product engineer at Scale AI and Dagster, then as a venture capitalist — and she continued writing code throughout, building systems that automated company-announcement monitoring and identified fast-growing open-source projects.

In a detailed March 2026 account of her product-management work, Wu described how she used Claude Code internally from the moment it became available in fall 2024, building Streamlit applications that analyzed large-scale user feedback, running evaluations to assess potential benchmarks, and creating reinforcement-learning environments to understand training better. Those projects, she wrote, took hundreds of hours of prompting with Sonnet 3.5 — without her writing any of the code by hand.

She also tested successive Claude models on the same exercise: adding a table tool to Excalidraw. The attempts began with Sonnet 3.5 in October 2024, when Claude still failed at the task. Opus 4 occasionally succeeded by June 2025, and Opus 4.6 later completed such feature requests reliably enough to demo live in front of thousands of professional developers.

The product she leaves behind

Wu's farewell thanked the teams behind Claude Code, Cowork and Tag, describing the products as the sum of thousands of ideas from colleagues and crediting user feedback with shaping much of what shipped. She called helping build Claude Code into an industry-defining product "the journey of a lifetime."

The product she leaves has changed dramatically in two years. Claude Code began as a manually approved coding assistant — permission prompts for every action, used mostly for answering questions and writing tests. By August 2026, Anthropic had flipped the default: new sessions on Pro, Max and Team plans now run in auto mode, trusting Claude's judgment to auto-approve routine actions, conduct large migrations, and build entire products, with a classifier stepping in to block irreversible or destructive actions.

That shift — from tool to autonomous collaborator — is the arc Wu presided over, and it explains both her prominence and the weight of her departure. Claude Code is widely credited with helping drive Anthropic's enterprise revenue growth, and it is the product most frequently cited in the competitive battle with OpenAI's Codex and Google's agentic coding tools.

Departures before a headline IPO

Timing is the subtext nobody at Anthropic will comment on. The company is preparing for an IPO that analysts expect to be one of the largest technology listings of the decade, and pre-IPO departures of senior product leaders inevitably draw scrutiny from investors assessing whether key institutional knowledge is walking out the door. Business Insider noted the exit comes before the big listing, and Wu is far from alone: Anthropic has seen several senior departures this year, even as it continues to recruit aggressively.

Anthropic has not announced a successor for the Claude Code product role. What happens next will be watched closely — not just by the developer community that adopted the tool, but by the investors sizing up the company's prospectus. In a business where the product roadmap is the valuation, losing the person who steered the flagship product is more than a personnel note; it is a data point.
