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 has operated as a separate company ever since Microsoft acquired it in 2018 for $7.5 billion, but Dohmke’s departure is part of a big shakeup to the way GitHub operates. Microsoft isn’t replacing Dohmke’s CEO position, and GitHub will now be fully part of Microsoft instead of being run as a separate entity.
“GitHub and its leadership team will continue its mission as part of Microsoft’s CoreAI organization, with more details shared soon,” says Dohmke in a memo to GitHub employees today. “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’s CoreAI team is a new engineering group led by former Meta executive Jay Parikh. It includes Microsoft’s platform and tools division and Dev Div teams, with a focus on building an AI platform and tools for both Microsoft and its customers. Parikh described his vision of an AI agent factory in an interview with Notepad earlier this year, and how he is convincing the developer division of Microsoft to adopt AI.
“Just like how Bill [Gates] had this idea of Microsoft being a bunch of software developers building a bunch of software, I want our platform, for any enterprise or any organization, to be able to be the thing they turn into their own agent factory,” said Parikh.
Dohmke appeared on Decoder last week, discussing Copilot, vibe coding, and what’s next for AI. Dohmke was thinking a lot about the competition and GitHub’s role in the future of software development, and now he’s about to leave to potentially create some more competition for Microsoft’s AI efforts.
