About us
OpenSource was built by a former software developer and a seasoned recruiter who have sat on both sides of the hiring table. We embed with your team to hire some of the brightest minds in tech, product and data.
Co-founder · Former software developer
George spent years as a software developer before co-founding OpenSource. Having been the person on the other side of the technical interview, he runs the technical screening that means clients only meet engineers who can genuinely do the job. He writes our engineering-hiring and salary research from that first-hand perspective.
Co-founder · Recruitment
Harry has spent a decade scaling teams for VC-backed startups and scale-ups across the UK, Europe and the US. He leads how OpenSource partners with clients — embedding with teams, understanding what great looks like, and moving fast enough to land the people everyone else is chasing.
We built OpenSource because we had both seen how badly technical hiring is usually done. One of us was the engineer on the other side of the interview, watching good people get filtered out by processes that did not understand the work. The other spent years in recruitment, watching agencies fire over CVs and hope something stuck. We knew it could be better, so we made the technical screen the centre of everything: every candidate is assessed by us, people who have done the job, before they ever reach a client.
That one decision changes the whole experience. Clients stop wasting interview time on people who cannot do the work, and candidates get a process run by someone who genuinely understands what they do. We stay deliberately hands-on and embed with the teams we hire for, because good hires come from real relationships, not transactions. It is why clients keep coming back, and why we can move fast enough to land the people everyone else is chasing.
