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.

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

GitHub Chief Executive Thomas Dohmke said on Monday he will leave the Microsoft-owned code-hosting platform to launch a new startup, capping a tenure that included a major push into artificial intelligence through the company's Copilot products.
