Founders and product teams are often told to "build an MVP" when what they actually need is a prototype or a proof of concept. Each answers a different question, takes a different amount of effort, and produces a different output. Picking the right one saves time and keeps budget for the step that genuinely needs it. This guide explains the differences and offers a simple way to decide.
What It Is
A proof of concept (PoC) answers a technical question: can this be done? It might test whether an API returns the data you need, whether a model can classify documents accurately enough, or whether two systems can integrate within acceptable limits. A PoC is usually narrow, disposable, and not shown to customers. A prototype answers a design and usability question: does this make sense to users? It may be clickable screens or a lightweight front end without real data, used to test flows, gather feedback, and align stakeholders. A minimum viable product (MVP) answers a market question: will real users use this, and will they come back or pay? An MVP is working software with real data, deployed to real users, deliberately limited to the smallest set of features that delivers the core value. Because real people use it, an MVP needs proper attention to authentication, data handling, and maintainability, even if the feature set is small.
Who It Is For
This comparison is useful for:
- Founders preparing to commission their first build
- Product teams in established companies exploring a new digital service
- Investors or boards asking what the next milestone should produce
- Teams that built a prototype and are unsure whether it can become the product
What It Helps Clarify
Choosing between them helps clarify:
- Which risk is largest right now: technical feasibility, usability, or market demand
- What evidence the next decision needs, and who will make it
- How much of the work is expected to be kept versus thrown away
- Whether security, data protection, and app-store requirements apply yet
What's Included
- Choose a PoC if the core technology, integration, or data source is unproven
- Choose a prototype if the workflow or user experience is unclear, or stakeholders disagree on what the product looks like
- Choose an MVP if feasibility and core flows are understood and you need real usage evidence
- For any option: write down the question it must answer and how you will judge the result
- Define what will happen next for each outcome: proceed, adjust, or stop
- Decide early whether PoC or prototype code will be reused; usually it should not be
- For an MVP: confirm authentication, data storage, privacy, and hosting choices before build
What's Not Included
- A claim that any of these approaches ensures product-market fit or adoption
- Turning a throwaway prototype into production software without review
- Marketing or user acquisition
- Fixed budget figures; effort depends on scope, which is confirmed in writing
When to Choose It
If you can state your biggest unknown in one sentence, you can usually choose. "We don't know if the integration works" points to a PoC. "We don't know if users understand the flow" points to a prototype. "We don't know if users will adopt it" points to an MVP. If you cannot yet state the unknown, start with discovery work to define it.
Our Approach
Work in the order that removes the most risk for the least effort. Many products benefit from a short discovery or blueprint phase, a focused PoC on the hardest technical question, and then an MVP built on what was learned. Our Technical Feasibility & PoC service produces a feasibility decision record and validation summary for a defined technical question. Our App MVP Sprint delivers a scoped, working first version with handoff materials, built with attention to authentication and data handling from the start. Where users, flows, or scope are still unclear, a Discovery Sprint or Product Blueprint & Scope engagement can come first. Whatever path you choose, agree the question, the boundary, and the handoff in writing before work starts, so the output can be judged against what was intended.
