GitHub CEO Thomas Dohmke announced his resignation in August 2025. After nearly four years leading GitHub, Dohmke will remain until the end of 2025 to support the transition before leaving to start a new tech startup, returning to his “founder roots.” His departure signals a major restructuring, with Microsoft integrating GitHub fully into its CoreAI team, led by Jay Parikh. Microsoft will not be replacing the CEO role at GitHub, effectively ending GitHub’s independence as an entity and folding it under direct Microsoft AI engineering operations.
During Dohmke’s tenure, GitHub grew significantly, with over 1 billion repositories and 150 million developers, and saw a doubling of AI-related projects. The transition places GitHub more closely aligned with Microsoft’s AI platform, reflecting the increasing role of AI tools like GitHub Copilot.
The leadership restructuring will have GitHub management report to several Microsoft executives with Julia Liuson overseeing revenue, engineering, and support, and Mario Rodriguez reporting to the head of Microsoft’s AI platform products, Asha Sharma.
In summary, Dohmke’s resignation marks the end of GitHub’s independent CEO leadership as it becomes integrated into Microsoft’s CoreAI division, while Dohmke moves on to found a new startup.
