About GitHub
The platform most modern engineering teams already build on.
GitHub launched in 2008, founded by Tom Preston-Werner, Chris Wanstrath, PJ Hyett and Scott Chacon as a hosting service built around the Git version-control system. Microsoft acquired the company in October 2018 for 7.5 billion dollars in stock, and it has run as a Microsoft subsidiary since. The platform now reports more than 100 million developers and over 420 million repositories, with a product surface that has grown well beyond source-code hosting: GitHub Actions for CI/CD, GitHub Copilot for AI-assisted development, Issues and Projects for work tracking, Codespaces for cloud dev environments, Advanced Security for dependency and secret scanning, and Packages for artifact distribution.
For most engineering organisations GitHub is no longer just where the code lives. It is where pull requests get reviewed, where pipelines run, where bugs are filed and triaged, where dependency vulnerabilities show up, and increasingly where AI-suggested code lands in production. That is plenty of telemetry, and the built-in Insights and Security tabs cover the team-level view well. The harder questions live across GitHub and the systems around it: how PR cycle time per team tracks the deploy frequency the leadership team reports, how Copilot adoption maps to defect rates, which open vulnerabilities sit on services that touch customer data, and which repos have quietly gone unmaintained. Pulling the GitHub metadata into a warehouse is how those questions stop being a quarterly screenshot from the Org Insights page.
