What clients say
Verified reviews from the teams we've built with.
★★★★★
We needed a couple of extra developers to help us move faster on our product. ExtTech joined the project without much onboarding and got familiar with the codebase pretty quickly. Communication was straightforward, and when priorities changed, they adapted without making things complicated. We were able to get a lot more done in a short time.

Michael T.Product Manager · SaaS startup, United States
★★★★★
ExtTech helped us with the development of our HealthTech platform, mainly on the backend side. The team was easy to work with and didn't need constant supervision. They also caught a few issues in our existing setup and suggested better solutions instead of just implementing the tasks as written. Overall, a very solid experience.

★★★★★
We brought ExtTech in when our internal team was getting stretched with a new product release. They helped us cover both backend and frontend work and were able to start contributing quite quickly. There were a few changes to the scope along the way, but the team handled them well and kept things moving. I'd definitely consider working with them again.

faq
Questions clients ask us
Straight answers before we even get on a call — no fine print, no surprises.
How quickly can you start?
Usually within 1–2 weeks. We can ramp a single engineer or assemble a small cross-functional team, depending on what you need.
Can you work with our existing team?
Absolutely — that's what "extension" means. Our engineers plug into your existing team, processes and codebase, follow your standards, and work as one team, not a separate vendor.
What engagement models do you offer?
Time & Materials, Fixed-scope, or a Monthly dedicated team. You can scale the team up or down as priorities change.
Who owns the code and IP?
You do — 100%. All code, deliverables and intellectual property belong to you. We're glad to sign an NDA before we get into specifics.
How do we communicate?
In English, with solid daily overlap for EU and US hours, using your tools — Slack, Jira, GitHub, whatever your team already runs on.
Can we scale the team later?
Yes. Add specialists or reduce the team as the roadmap evolves — that flexibility is the whole point of an extension team.
What if the collaboration isn't working out?
A short notice period and a clean handover: documented code, transferred access, no lock-in. A low-risk partnership is how we keep clients.
