Founders often ask for "an MVP" when what they really need is a quick technical experiment or a clickable design. Asking for the wrong thing can mean paying for months of work when a few weeks would have answered the real question.
A proof of concept (PoC) answers "can this be built?", a prototype answers "how will it work and will users understand it?", and a minimum viable product (MVP) answers "will real users use it and pay for it?". A PoC is a technical experiment, a prototype is a model of the experience, and an MVP is a working product released to real customers.
What is a proof of concept?
A proof of concept is a small, focused experiment that tests technical feasibility. It is usually built for the internal team, investors or a technical stakeholder, not for end users. The code is often throwaway and the interface may be non-existent.
Typical PoC questions include:
- Can a language model extract the right fields from our invoices with acceptable accuracy?
- Can we integrate with this bank's or courier's API in the way we need?
- Can the app process camera frames on a mid-range Android phone fast enough?
- Will this database design handle the volume of data we expect?
If your idea depends on something that has not been done before, or on a third-party system you do not control, a PoC is the sensible first step. It is particularly common in AI projects, where you need to know whether a model can do the job on your real data before you design anything around it.
What is a prototype?
A prototype is a representation of how the product will look and behave. It ranges from paper sketches and wireframes to high-fidelity clickable designs in Figma that feel almost like a real app. Prototypes are for users, designers, stakeholders and investors. They test usability, flow and desirability without the cost of engineering.
A good prototype lets you:
- Run usability tests and see where people get stuck.
- Align founders, designers and developers on what is being built.
- Show investors or early customers a concrete vision.
- Give developers a clear reference that reduces guesswork and rework.
Prototypes usually do not store real data or connect to real systems, which is exactly why they are fast to change.
What is a minimum viable product?
An MVP is the smallest working version of your product that delivers real value to real users. It is built with production-quality code for the features it includes, it is deployed, and people can sign up, use it and ideally pay for it. The "minimum" refers to scope, not quality: an MVP should do a few things reliably rather than many things badly.
An MVP tests the biggest business questions: will people adopt it, keep using it and pay for it? It also starts generating the usage data you need to decide what to build next. Our ultimate MVP development guide covers how to scope one.
MVP vs prototype vs proof of concept: side by side
| Proof of concept | Prototype | MVP | |
|---|---|---|---|
| Main question | Can it be built? | How will it work for users? | Will people use and pay for it? |
| Audience | Internal team, technical stakeholders | Test users, stakeholders, investors | Real customers in the market |
| Working code | Yes, often throwaway | Usually none | Yes, production quality |
| Real data | Sometimes, a sample | No, mock data | Yes |
| Relative effort | Small, narrow | Small to medium | Medium to large |
| Output | A yes or no on feasibility | Validated flows and designs | A live product and usage data |
Which one should you build first?
The right starting point depends on where your biggest uncertainty lies.
Start with a proof of concept if...
- Your product relies on new technology, AI accuracy or a difficult integration.
- Investors or partners need evidence that the core technology works.
- Failure of the technical piece would make the whole idea pointless.
Start with a prototype if...
- The technology is well understood but the user experience is not.
- You need to test flows with users or win buy-in from stakeholders.
- You want a precise reference before asking developers for an estimate.
Go straight to an MVP if...
- You have already validated the problem with real users (see how to validate an app idea).
- The technology is proven and the flows are clear.
- The fastest way to learn is to put something live in front of paying customers.
Can a prototype or PoC turn into the MVP?
Sometimes, but plan for it carefully. Design prototypes carry straight over: the Figma files become the basis for the MVP's interface. PoC code is a different matter. It is usually written quickly to answer one question, without the testing, security and structure a live product needs. Reusing the core idea is fine, but most teams rewrite PoC code properly rather than shipping it.
Common mistakes to avoid
- Calling a big product an MVP. If the scope includes every feature on the wish list, it is not minimum.
- Shipping a prototype as a product. Clickable designs do not handle real data, payments or security.
- Skipping the PoC on risky technology. Discovering late that an integration or model will not work is costly.
- Testing with the wrong audience. Feedback from friends rarely reflects how paying customers behave.
Key takeaways
- A PoC tests feasibility, a prototype tests the experience, and an MVP tests the market.
- Start with whichever one addresses your biggest unknown, and do not pay for an MVP when a PoC or prototype would answer the question.
- Design work carries forward into the MVP, but PoC code is usually rewritten for production.
