The problem

Hiring engineers shouldn’t stall your roadmap

It takes too long

A senior engineering hire in the US often takes 2–3 months. Your runway doesn’t wait for a full hiring cycle.

Founders end up recruiting

Screening CVs and running tech interviews pulls you away from product, customers and fundraising.

A bad hire costs a quarter

On a small team, one wrong senior hire sets the whole roadmap back by months.

Hiring models

Two ways to build your team. You choose.

Start with augmented engineers and convert them to full-time later, or hire your core team directly from day one.

FAQ

Questions founders ask us

What’s the difference between staff augmentation and outsourcing?

With outsourcing, a vendor delivers a project. With staff augmentation, engineers work inside your team, follow your processes and report to your leads, while we handle employment and admin.

Where are your engineers located?

Our talent network spans Europe, Israel and Latin America, with at least 4 hours of overlap with US working hours.

How do you vet candidates?

A recruiter screen, an English check and a technical interview with a senior engineer in the same stack, plus reference checks for senior roles.

Who owns the IP?

You do. Every engineer signs an NDA and an IP assignment agreement before day one.

What if the engineer isn’t a fit?

We replace them at no extra cost: anytime for staff augmentation, within 90 days for direct hire.

Can I hire an augmented engineer full-time later?

Yes. After 6 months the conversion is free; earlier, a reduced placement fee applies.

How fast can someone start?

You get the first vetted candidates within 48 hours; most augmented engineers start within 1–2 weeks.

Do you work with pre-seed or non-technical founders?

Yes. Our free technology consultation helps you define the stack and team composition before hiring.
