An MVP is not a half-built product. It is the smallest complete loop a paying user can finish. SaaS development that skips tenancy, billing, or permissions usually has to be rewritten when the second customer arrives.
Define the loop before the feature list
Write the job: who signs up, what they set up, what they do weekly, and how they get value. Everything outside that loop is a later release. This is how Orbitdor keeps SaaS roadmaps honest.
Architecture minimums for a real MVP
- Clear tenant isolation for data and configuration
- Role-based access that will not collapse when you add a second workspace
- Billing that can be swapped or extended without a rewrite
- Observability so you can see failures before customers email you
Delivery that creates evidence
Ship in milestones that a founder can demo. Each increment should leave the product more usable, not just more coded. Design, engineering, and product decisions stay in the same conversation so the interface does not drift from the data model.
