02

Founders whose build stalled

A developer hire fell through or a freelancer disappeared, and the product still needs to ship.

03

Founders racing a date

You need a working first version before a fundraise, a pilot or a launch.

Frequently asked

Good questions.

How much does an MVP cost?

Most MVPs start from $8k. The exact price comes from the one-week scoping sprint ($999), which ends with a fixed quote. If you build with us, the sprint fee is credited against the build.

How long does it take?

Typically 4–6 weeks from the end of the sprint to launch, depending on scope. You’ll see working software every week along the way.

Why not hire a freelancer?

A freelancer is usually one person covering design, frontend, backend and deployment. We bring design and engineering together, agree scope and price up front, and show progress weekly, so your launch doesn’t depend on one person staying available.

What if I want to take the code in-house?

You own the code, infrastructure and accounts from day one. When you’re ready, we hand over with documentation, or keep improving the product on a monthly plan from $1,500.

Do I have to build with you after the sprint?

No. You keep the scope, wireframes and plan, and you can take them to any team. If you do build with us, the $999 is credited against the build.
