P. J. Hyett, cofounder of GitHub, helped create the platform that became the default home for modern software collaboration, reshaping how developers build, review, and ship code at global scale. As GitHub evolved from a developer tool into a foundational layer of the internet’s software stack, Hyett played a key role in its early product DNA and community-first growth, helping turn open-source momentum into a dominant enterprise platform. GitHub’s rise culminated in its landmark acquisition by Microsoft, cementing Hyett’s place among the entrepreneurs who defined the modern developer economy.
