"GitHub and its leadership team will continue its mission as part of Microsoft’s CoreAI organization, with more details shared soon," Dohmke wrote. "I’ll be staying through the end of 2025 to help guide the transition and am leaving with a deep sense of pride in everything we’ve built as a remote-first organization spread around the world."

The move comes as GitHub is facing growing competition from companies like Google and Cursor over AI tools for programmers.

Thomas Dohmke is calling it quits as GitHub’s CEO after nearly four years at the helm, marking a significant shift in how Microsoft manages one of its most valuable acquisitions. The departure signals Microsoft’s push to bring GitHub even closer to its artificial intelligence ambitions.
