"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."

Microsoft is moving GitHub into its CoreAI team, following the resignation of GitHub CEO Thomas Dohmke today. After nearly four years as CEO, Dohmke is leaving GitHub to “become a startup founder again,” and pursue opportunities outside of Microsoft and GitHub.

GitHub CEO Thomas Dohmke will leave his position at the end of the year. He joined the developer platform from Microsoft in 2021.
