GitHub CEO Thomas Dohmke has resigned from his position, triggering a major restructuring for the company. After nearly four years at the helm, Dohmke is stepping down signaling his departure from both GitHub and Microsoft. Following his resignation, Microsoft is moving GitHub directly into its new CoreAI team. Reportedly, Microsoft will not replace Dohmke’s CEO role, effectively ending GitHub’s status as a separate entity and integrating it fully into its operations.“Still, after all this time, my startup roots have begun tugging on me and I’ve decided to leave GitHub to become a founder again,” Dohmke said. “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,” he added.

GitHub to merge in Microsoft AI engineering team led by Jay Parikh

Dohmke mentioned that GitHub will now be a part of Microsoft’s CoreAI team – a new engineering group led by former Meta executive Jay Parikh. It is focused on building AI platforms and tools for both internal use and for Microsoft’s customers. The division includes Microsoft’s platform, tools, and Dev Div teams.According to Dohmke, GitHub Copilot “is the leader of the most successful and thriving market in the age of AI, with over 20 million users and counting.” “In just the last year, GitHub Copilot became the first multi-model solution at Microsoft, in partnership with Anthropic, Google, and OpenAI. We enabled Copilot Free for millions and introduced the synchronous agent mode in VS Code as well as the asynchronous coding agent native to GitHub,” he added.In a post on X (formerly Twitter), Dohmke thanked Satya Nadella “for the ride of a lifetime”.“Thank you to @satyanadella, Julia Liuson, so many countless people, and most importantly, thank you to all Hubbers for the ride of a lifetime,” he said.
