GitHub

Market leader in software development platforms and version control hosting

GitHub is a comprehensive software development platform that enables developers to build, scale, and deliver secure software. Founded in 2008, GitHub has become the world's largest host of source code, serving over 100 million developers and 4 million organizations globally. The platform provides Git-based version control, code review, project management, CI/CD automation, and security features that support the entire software development lifecycle. Acquired by Microsoft in 2018 for $7.5 billion, GitHub operates as a subsidiary while maintaining its distinct brand and platform. The company offers both cloud-hosted services (GitHub.com) and self-hosted enterprise solutions (GitHub Enterprise Server). GitHub has become essential infrastructure for open source development and enterprise software teams alike, hosting millions of repositories including critical open source projects. While GitHub is not an AdTech company, it serves the technology ecosystem broadly and is used by AdTech companies for software development, API management, and developer collaboration. GitHub's marketplace, developer tools, and automation capabilities support the technical infrastructure that many AdTech platforms rely upon for building and deploying their advertising technology solutions.
