How long does a MERN MVP take to build?

A focused MERN MVP ships in 8 to 12 weeks with two engineers. The first two weeks go into discovery and scope locking. Sprints 1 to 4 build the core MERN product over eight weeks. Sprint 5 handles Stripe billing, polish, and edge cases. The final sprint covers QA, load testing, and production deployment. Timeline is protected by locking scope in week one. We do not give a timeline before seeing what you actually want to build.
