Most SaaS MVPs fail for the same reason: they try to be a cheaper version of the finished product instead of a test of the riskiest assumption.
Start with the riskiest assumption
Write down the one belief that, if wrong, sinks the business. Usually it is one of these:
- Demand: will the people you have in mind pay to solve this problem?
- Value: does your approach solve it noticeably better than what they use today?
- Reach: can you get it in front of those people at a sensible cost?
Your MVP exists to test that belief as cheaply and quickly as possible.
Cut everything that does not serve the test
For each feature, ask: does the experiment fail without it? Sign-in and billing usually stay, because asking for payment is the strongest signal of demand. Team management, granular permissions and an elaborate settings screen can usually wait.
Decide what success looks like before you build
Agree a measurable outcome up front, such as ten paying customers in the first month or a weekly active rate above 40%. Without it, every result looks like a reason to keep building.
Build it properly anyway
"Minimum" describes scope, not quality. We still use a typed codebase, automated checks and a real database, because the MVP that works becomes version one, and rewriting it later costs more than doing it right now.
