You have a cool idea. You're excited to start coding. But before you dive in, you need to answer one important question: should you build a Proof of Concept (PoC), a Prototype, or jump straight to a Minimum Viable Product (MVP)?
Choosing the wrong path can waste months and burn through budget. Many startups fail not because the idea was bad, but because they built something nobody actually wanted or that wasn't technically feasible.
These three terms are often mixed up, but each serves a completely different purpose and validates a different type of risk.
What Is a Proof of Concept (PoC)?
A PoC is all about answering one question: Can this even be built?
It focuses purely on technical feasibility — testing integrations, algorithms, performance, new technologies (like AI/ML), or complex architecture. There's usually no UI, no design, and no real user flow. It's often a quick, messy internal spike.
Typical timeline: A few days to 2–3 weeks.
Best used when: You're working with unproven tech, heavy integrations, or high technical uncertainty.
If the PoC fails, you stop early with almost no loss.
What Is a Prototype?
A Prototype shifts focus from technology to the user experience.
Here you validate whether the product is understandable, intuitive, and the flows make sense. It can be low-fidelity wireframes or high-fidelity clickable designs in Figma. No real backend is needed — the goal is to test navigation, interactions, and gather early feedback from stakeholders or potential users.
Typical timeline: 2–6 weeks.
Best used when: You have complex user journeys, marketplaces, dashboards, or any product where UX is critical.
Fixing design issues at the prototype stage is cheap and fast.
What Is a Minimum Viable Product (MVP)?
An MVP is the first real version of your product that actual users can interact with. It contains only the core features needed to solve one key problem and deliver value.
Unlike a prototype, an MVP has a working backend, real functionality, and production-level quality (even if the scope is small). The main question it answers is: Will people actually use this?
Typical timeline: 2–6 months (depending on complexity).
Best used when: You want to validate real market demand, user behavior, and your business model.
A good MVP is not "cheap and dirty" — it's focused and solid.
PoC vs Prototype vs MVP – Quick Comparison
| Aspect | Proof of Concept (PoC) | Prototype | Minimum Viable Product (MVP) |
|---|---|---|---|
| Main Question | Can it be built? | Is it usable and intuitive? | Will people use & pay for it? |
| Focus | Technical feasibility | User experience & flows | Market & business validation |
| Functionality | Minimal (tech spike only) | Clickable / simulated | Fully working core features |
| Timeline | Days – 3 weeks | 2–6 weeks | 2–6 months |
| Risk Addressed | Technical risk | Design / UX risk | Market risk |
| Cost Level | Low | Medium | Higher |
How to Choose the Right One
High technical uncertainty? → Start with a PoC
Complex UX or many user flows? → Build a Prototype
Need to test real user adoption? → Go for an MVP
You don’t always need all three. Some projects combine PoC + MVP, others skip straight to MVP if the tech and UX risks are low. The key is to identify your biggest risk first and validate it as cheaply as possible.
Early validation is one of the smartest things you can do as a developer or founder.
If you're working on a product and need help with any of these stages — whether it's a quick technical PoC, a polished interactive prototype, or a high-quality MVP — the team at Lampa.dev specializes in exactly this kind of work. They help turn ideas into validated, production-ready solutions efficiently.
