Implications of Thomas Dohmke's Leaving for GitHub's Future Direction
Thomas Dohmke, the CEO of GitHub, has announced his plans to step down at the end of 2025. In a move that signals a shift towards tighter integration with Microsoft's AI-focused strategy, GitHub will no longer have a direct replacement for Dohmke as CEO. Instead, GitHub's leadership will be integrated into Microsoft's CoreAI division.
Dohmke joined GitHub in 2015 following Microsoft's acquisition of his startup, HockeyApp. Under his leadership, the number of open source projects on GitHub has consistently increased. One of his most significant achievements was the growth of GitHub's coding support tool, Copilot, which now boasts over 20 million users. Copilot, first launched under the leadership of Nat Friedman, has seen an increase in popularity under Dohmke's tenure.
Julia Liuson, head of Microsoft's Developer Division, will oversee GitHub’s revenue, engineering, and support functions. GitHub’s chief product officer, Mario Rodriguez, will report to Microsoft AI platform vice president Asha Sharma. This represents a shift from GitHub's prior largely independent operation.
The CoreAI division at Microsoft, announced in January 2025, focuses on AI platform and tool development. The division is led by former Meta executive Jay Parikh. The remaining GitHub executives will report to Liuson, as suggested by the memo distributed by Parikh.
The deeper integration between GitHub and Microsoft appears to be coming, following Dohmke's decision to step down. This integration is not surprising given that GitHub was acquired by Microsoft in 2018 for a fee of $7.5 billion. In the last year alone, the number of AI projects on GitHub has doubled. Last year, GitHub became the "first multi-model solution" at Microsoft, allowing developers to draw on a range of options, including those from OpenAI, Google, and Anthropic.
Dohmke has worked with many exceptional individuals during his time at GitHub, including Hubbers, Microsofties, customers, partners, GitHub Stars, open source maintainers, and developers worldwide. He plans to launch a new venture after his departure from GitHub.
As of now, GitHub has over 150 million registered developers, a significant increase from 73 million in 2021. The future of GitHub under Microsoft's CoreAI division remains to be seen, but one thing is certain: Dohmke's leadership has played a crucial role in the platform's growth and success. He will stay with GitHub through the end of 2025 to help guide the company's transition.
