GitHub Chief Executive Officer Thomas Dohmke said he will leave the Microsoft-owned code-hosting platform after nearly four years in the role, staying through the end of 2025 to manage the transition while he prepares to start a new venture. Microsoft does not plan to appoint a replacement. Instead, GitHub’s leadership team will be folded into the company’s recently created CoreAI engineering group, led by former Meta executive Jay Parikh. Julia Liuson, president of Microsoft’s developer division, will assume responsibility for GitHub’s revenue, engineering and support functions, and Chief Product Officer Mario Rodriguez will report to Asha Sharma, head of AI platform product. The reorganization ends the relative autonomy GitHub maintained following Microsoft’s $7.5 billion acquisition in 2018 and underscores the parent company’s push to concentrate artificial-intelligence initiatives. GitHub Copilot—its AI coding assistant—now counts about 20 million users, while the broader platform hosts more than 1 billion repositories and serves roughly 150 million developers amid intensifying competition in AI-powered software tools.
