How we work with clients
We embed with your team rather than firing over CVs: we learn your stack, your bar and what “great” looks like, then bring a shortlist built on evidence. Clients choose the model that fits — contingent, embedded (RPO) or retained search — and every candidate is technically screened before they reach you.

FAQ
Working with us, answered.
What kind of companies does OpenSource recruit for?
Venture-backed startups and scale-ups, from seed-stage teams making their first senior engineering hire to Series C companies building out product, data and leadership functions, in fintech, SaaS, marketplaces, AI and data, health and climate. We also work with established technology teams inside larger businesses when the roles are genuinely technical.
Are the testimonials on this page real?
Yes. Every quote is from a named client who gave permission for it to be used, with their role and company stated where they allowed it. We do not invent testimonials, review counts or client logos.
How does OpenSource work with a new client?
A founder takes the brief, agrees the model (contingent, retained or embedded), runs the search and technically screens every candidate before you see a CV. The person you speak to on the first call is the person running your search through to the start date.
What does OpenSource not do?
We do not run high-volume or non-technical recruitment, we do not send unscreened CVs, and we do not take on roles we think we cannot fill well. If a brief is wrong for us we say so and, where we can, point you to someone better placed.
