International SOSDesign behind a mission-critical risk platformVetting & matching
Technical interviews by senior peers, references, and fit for your team — before you see a CV.
Staffing
Senior software staffing embedded in your team.
Full-time senior engineers and designers embedded in your squad. We headhunt, employ, pay and equip them — you run the work.
Two models
We find them, or you do. We employ them either way.
Both put a full-time person inside your team, in your tools, working only for you. They differ in who carries the search.
Staff Augmentation
Rent the seatYou tell us the stack, seniority and team. We shortlist from people we already know — most have worked with us before — and you interview the final two or three.
- Two weeks to seatTypical time to a staffed, onboarded engineer.
- Seniors onlyNo bench, no ramp-up padding, no juniors billed as seniors.
- Flex monthlySeats scale up or down with your runway.
- Replacement is on usIf someone isn’t working out, that’s our problem.
