/ statement

We build and operate web platforms other teams can run on without our help.

Devbuildstudio is a senior engineering firm. We work on builds in the 6–14 week range, plus retainers and fixed-fee audits. Most of our clients are operating teams who already understand their problem and need a partner who will ship the system, hand over the runbook, and stay on the rota.

§ 4.0 Common questions

Three things people ask on the first call.

The full list lives on the studio page — these are the ones that come up every time.

Q.01

Do you sign NDAs?

Yes, standard mutual NDAs the same week we meet. We will not sign one-sided NDAs that restrict our right to describe the general nature of work.

Q.02

Will I own the code?

Yes. All source code, infrastructure-as-code, and operational scripts are assigned to you at delivery. We retain no rights other than to mention the engagement existed.

Q.03

Where do you host?

By default: Hetzner Falkenstein and Helsinki, with Cloudflare in front. We are happy to deploy into your AWS / GCP / Azure account if you prefer.
