Building on Phase Two’s focus on enterprises, this report spotlights the UK-based individuals forming the globally employed open source workforce — the crew of the “Open Source Submarine” under the UK’s digital economy. The first report anywhere to seek to understand this workforce, it analyses GitHub data revealing 31,800 UK contributors and maintainers, explores who they are, what they do and how they work, and makes the case that leveraging open source contribution is how the UK develops missing skills, stems talent flight and builds its future tech sector.

Executive Summary
The Open Source Submarine surfaces
- The first report to map the UK’s open source workforce: 31,800 UK contributors and maintainers identified from GitHub data, to be tracked quarterly — a picture no other country has
- These individuals contributed 27% of UK Tech Sector GVA in 2022, yet remain largely invisible to their home country while being sought-after employees of Bay Area tech
Skills through contribution
- Open source contribution builds a “living CV” on GitHub: as Greg Kroah-Hartman puts it, “If you get five commits in the [Linux] kernel you will get offered the job”
- Contribution offers hands-on experience, mentoring and skills development that formal teaching lacks — and access to highly paid international remote employment from anywhere in the UK with connectivity
What the UK must do
- Get to know its open source workforce and leverage it: retain talent through remote international work, develop commercialisation skills (still a Bay Area strength), and use contribution to diversify the future tech workforce
- The UK is number one in Europe by developers and lines of code contributed — a foundation for the “next Silicon Valley” ambition
