Microsoft-owned GitHub announced that CEO Thomas Dohmke will leave his position by the end of 2025, ending a nearly four-year tenure. Following his exit, GitHub will be fully integrated into Microsoft’s CoreAI division, marking a strategic shift in the company’s structure amid intensifying AI competition.
GitHub, Inc., headquartered in San Francisco, California, is a leading platform for software development and code hosting, widely used by developers worldwide to collaborate on projects, manage code repositories, and contribute to open-source initiatives. Acquired by Microsoft Corporation in 2018 for $7.5 billion, GitHub operates at the intersection of software engineering, AI-powered developer tools, and open-source innovation.
On August 11, GitHub confirmed that Chief Executive Officer Thomas Dohmke will step down by year-end. Dohmke, who led the platform since late 2021, said he plans to return to his entrepreneurial roots and start a new venture.
Microsoft has decided not to appoint a new CEO for GitHub. Instead, the platform will operate as an integrated part of Microsoft’s CoreAI organisation. This move comes as Microsoft deepens its AI investment, leveraging GitHub’s tools and developer network to strengthen its position in the global software ecosystem.
Under Dohmke’s leadership, GitHub rolled out several AI-driven products, significantly enhancing the developer experience across all stages of the software lifecycle. India emerged as GitHub’s fastest-growing market, with over 18 million developers as of April 2025, up from 17 million six months earlier. The country now ranks second globally in open-source contributions and public Generative AI projects, with the latter category growing 79% year-on-year since 2024.
Globally, GitHub reported more than 150 million developers by the end of 2024. The platform also saw a doubling of AI-related projects in the past year, underscoring its expanding role in shaping the future of software development.
In his farewell note on GitHub’s blog, Dohmke highlighted major achievements during his tenure, including expanded platform accessibility, improved infrastructure reliability, and market entry into the EU and Australia. He emphasised that the momentum built over the last few years will continue under Microsoft’s leadership.
