When a company sets out to build software, three acronyms come up in the first conversation: POC, prototype and MVP. They get used interchangeably, and that is a fast route to misunderstanding. Each one answers a different question, appears at a different stage and consumes a different budget.
Mixing them up has real consequences: a wrong cost estimate, an unrealistic deadline, expectations that drift apart between the team and the board, sometimes a product that answers no question at all. Below we break the three terms down and show why an MVP has little in common with a beta.
Where the confusion comes from
All three terms belong to the early stages of product work, which makes them easy to blur. The trouble starts when one word means something completely different inside two people’s heads.
The board hears “we will build an MVP” and pictures a cheaper, unfinished version of the full application. The product team means the smallest product that actually works and can be handed to users. Two people, one word, two budgets and two deadlines. Before the first estimate lands, it pays to agree which of the three artifacts you are talking about.
POC: checking whether it will work at all
A POC (proof of concept) answers one question: can the assumed solution be built at all in the chosen technology. A POC ignores looks and the question of whether users will want the product. It checks technical feasibility and nothing else.
Situations where a POC makes sense:
- Can we integrate the ERP with a courier API so that shipment statuses update in real time.
- Can a machine learning model classify a document type with accuracy high enough to automate the process.
- Can a given library handle files of the size the project assumes.
The output of a POC is usually a script or a fragment of code that goes in the bin once it has answered the question. It is internal material, meant for the team. You run a POC when the project carries a concrete technical risk. When there is no such risk, this step can be skipped.
Prototype: how it will look and behave for the user
A prototype answers a different question: how the user moves through the product, whether the path makes sense and whether the interface communicates what it should. A prototype shows how something will look and click before any expensive code exists.
The layer underneath a prototype does nothing. Data is faked, buttons lead to further designed screens, and the whole thing serves conversation and testing. That lets you catch flaws in screen logic and gather feedback before developers write a single line of production code.
Prototype fidelity levels
Low fidelity: paper sketches or simple wireframes. They focus on layout and flow, without colour or detail. They take a few hours and are perfect for quickly discarding weak ideas.
High fidelity: a clickable design in Figma or a similar tool, with real look and interactions. For us this sits within design and UX work, because it lets you test the product with users almost as if it were finished.
The defining trait of a prototype is that it is a communication and validation tool. If it contains code, that code is disposable.
MVP: the smallest product that actually works
An MVP (minimum viable product) answers a market question: will people use the core value of the product, and often pay for it. The answer arrives as a working product used by real users on real data.
The key word is “viable”, meaning able to work. An MVP runs in production, sits on real code and can be developed further. Its scope is narrow while its quality stays full. One core flow done properly beats ten features done halfway. We usually build such an MVP as web applications or mobile applications.
What an MVP is not:
- A prototype with faked data handed to real users as a product.
- A POC script quickly wired to an interface.
- The full, target application with half its features hacked out just before the deadline.
Why an MVP and a beta are two different things
Since an MVP runs in production and reaches users, it is easy to confuse with a beta. The difference lies in scope, stage and purpose.
A beta is a stage of a product that already has almost its full intended scope. You release it to a limited audience to catch bugs and gather feedback shortly before general availability. The scope is broad, the moment is late, and the question is whether the finished thing works correctly.
An MVP is the first, deliberately narrow version of a product. Its job is to test the core hypothesis. The scope is narrow, the moment is early, and the question is whether the product should exist at larger scale at all. A beta tests the quality of a finished whole, an MVP tests the sense of an idea in its smallest useful form.
POC, prototype and MVP side by side
The table below sorts the three terms by what matters most for each of them.
| Aspect | POC | Prototype | MVP |
|---|---|---|---|
| Question it answers | Can this be built in this technology | How it will look and work for the user | Will people use it and pay for it |
| Form | Script, spike, disposable code | From a sketch to a clickable Figma design | A working product on real code |
| Audience | Team and technical stakeholders | Team, stakeholders, test users | First real users and customers |
| Reaches users | No | For testing, in a controlled way | Yes, in production |
| Production code | No, the code is disposable | Usually none | Yes, developed further |
| Typical time | A few days to 2-3 weeks | A few days to a few weeks | A few weeks to a few months |
How to pick the right step for your project
Not every project needs all three stages. The choice depends on where the greatest uncertainty sits.
- Technical risk: start with a POC.
- Uncertainty about the user path or scope: build a prototype.
- Idea confirmed technically and on paper: build the MVP.
In many projects the order is: POC, if needed, then prototype, then MVP. Some teams skip the POC because there is no technical risk and move from prototype straight to MVP. What matters is that each step answers the question that actually blocks the decision.
The most common MVP mistakes
- Calling a prototype an MVP and handing real users a product with faked data.
- Inflating MVP scope to the size of the full product, so validation comes too late and too expensive.
- Skipping validation and going straight to a full build without testing the hypothesis.
- Treating the MVP as a low quality product, which ends in conclusions drawn from data gathered on something broken.
Frequently asked questions
Does every project need a POC?
No. A POC makes sense only when the project carries a concrete technical risk. If the technology is proven, this step can be skipped and you move to a prototype or an MVP.
How much does an MVP cost?
The cost depends on the scope of the core hypothesis you want to test. The whole craft is in keeping that scope narrow, so the budget funds validation of the hypothesis rather than features nobody has confirmed yet.
Can an MVP be developed further?
Yes, and that is the point. An MVP is built on real code, so once the hypothesis is confirmed you grow it into the full product instead of rewriting everything.
Prototype or straight to MVP?
If the user path or the feature scope is uncertain, start with a prototype. It is cheaper and faster and lets you fix the design before expensive production code comes into play.
Where to start with Devhound
At Devhound we start by naming the question you actually need answered. Only then do we pick the tool: a POC for technical risk, a prototype for path and scope, an MVP to test the product on the market. That way the budget funds validation rather than guesswork.
If you are planning a project and want to work out which of these steps fits your case, get in touch. We will walk through your idea and point to the shortest route to testing it in practice.
