FAQ
Engagement questions.
How quickly can you start?
A technical consultation can usually happen within 48 hours, a discovery sprint within one to two weeks, and a full team is typically staffed within two to three weeks of the discovery sign-off.
Do you offer fixed-scope contracts?
Yes. After discovery we can commit to fixed-scope milestones with defined acceptance criteria. Ongoing product work is usually better served by a dedicated team retainer.
Where are your engineers based?
Tech Box operates as one distributed team across North America, Europe and Asia-Pacific, with a single delivery standard, shared tooling and a named tech lead accountable to you in US hours.
Will we own the code?
Yes. All work is done in your repositories and cloud accounts, and full IP assignment is written into our standard agreement.
Have a hard problem? Good.
Send us the thing the last three vendors couldn't finish. You get a scoped plan, a fixed first milestone, and a senior team — not a sales deck.
