Three terms most founders use interchangeably. They’re three different things, and picking the wrong one wastes a quarter.
At https://irpr.io we’ve watched dozens of founders kick off the wrong build because they confused MVP, prototype, and proof of concept. Each is a real engineering deliverable, but each answers a different question. Picking the right one before kickoff saves months.
Proof of concept (POC) answers a feasibility question. “Can this actually be built?” You build it when there’s genuine technical risk, a novel ML model, a new hardware integration, a performance constraint nobody’s hit before. POCs are throwaway. They have no UI, no user flow, no production-readiness. The output is a yes or no, with evidence.
Prototype answers a design question. “Will users actually use this the way we think?” You build it when there’s user-experience risk, a new interaction pattern, a new workflow, an unproven product loop. Prototypes are clickable but not real software (Figma, Framer, low-code tools). The output is a behavioral signal from real users.
MVP answers a market question. “Will customers pay for this?” You build it when there’s commercial risk, you have a working idea but don’t yet know if anyone will buy. An MVP is real production software with the smallest feature set that delivers the core value. The output is paying customers, not just feedback.
The order matters. POC before prototype if you have technical risk. Prototype before MVP if you have UX risk. MVP only when both technical and design questions are answered.
The expensive mistake is building an MVP before you’ve answered the prototype question, you ship working code that nobody actually wants. The opposite mistake (building a prototype when you should have just shipped an MVP) is also common, and just as costly.
The full https://irpr.io/services/saas-mvp-development we run starts with this question: which kind of risk are you actually trying to retire? Get it right and you save a quarter.
