An MVP is not a smaller product; it is an experiment that answers one question: will people pay to solve this problem? Everything in your 90 days should serve that question.
Weeks 1–2: Discover and scope
Interview users, map the core journey and cut the feature list until it hurts. If a feature does not help validate the core promise, it waits.
Weeks 3–10: Build in weekly increments
- Authentication, roles and a multi-tenant data model.
- The single workflow users came for.
- Subscription billing and basic analytics.
- Weekly demos so feedback arrives while changes are cheap.
Weeks 11–13: Harden and launch
Load test, secure the endpoints, automate backups and deploy with CI/CD. Invite a small beta cohort and watch what they actually do, not just what they say.
Launch when it is embarrassing but useful — not when it is perfect.
After launch, let usage data and customer conversations drive the roadmap. The MVP has done its job when it tells you what to build next.
