MVP development for founders who need a locked quote before they pay

Founder MVPs die on scope creep and surprise invoices. Lab Twelve runs MVP Sprint as a fixed package: full-stack architecture, Postgres, Redis, object storage, background jobs, analytics wiring, and production deploy—after the scope chat locks features in writing. You see the MVP Sprint price before checkout. Change requests are add-ons, not quiet scope stretch. This is for founders who know the job-to-be-done and need v1 shipped, not a research program.

FAQ

Questions for this build type

How is MVP Sprint different from Business App?

MVP Sprint adds Redis, jobs, storage, and full-stack ops patterns. Business App is tighter CRUD with fewer moving parts.

What is scope lock?

The quote matches the ScopeSpec at checkout. New ideas after lock are priced separately.

When should I not buy an MVP yet?

If you have not talked to ten users or cannot name one job-to-be-done, run interviews first. We will tell you.
