POC vs prototype vs MVP is a question of which risk you need to remove first. A proof of concept (POC) answers "can this be built?". A prototype answers "how will it work, and do users understand it?". A minimum viable product (MVP) answers "will real users use it, and pay for it?". Each costs more and takes longer than the one before, so building them in the right order saves money.
Many founders skip straight to an MVP when a two-week POC would have shown the core idea is not technically feasible, or build a polished prototype when the real uncertainty is whether anyone will pay. This guide defines each, compares them side by side with typical costs and timelines, and gives you a simple decision guide.
What is a proof of concept (POC)?
A proof of concept is a small, usually internal experiment that tests whether a specific technical idea works. It focuses on the riskiest technical assumption: can this model extract the right fields from our documents, can these two systems talk to each other, can this run fast enough on a phone? A POC has little or no user interface, is not built for real users, and is often thrown away once it has answered its question.
What is a prototype?
A prototype is a model of the product that shows how it will look and work, so you can test the experience with users and stakeholders before building it properly. It ranges from paper sketches and wireframes to clickable designs that feel like a real app but have no working backend. Its purpose is learning about usability and desirability, and getting buy-in from investors or internal sponsors.
What is a minimum viable product (MVP)?
A minimum viable product is the smallest working version of a product that real users can use to get a real job done, released so you can learn from actual behaviour. The Lean Startup approach describes building an MVP "to begin the process of learning as quickly as possible", within a build-measure-learn loop. Unlike a prototype, an MVP has real code, real data and real users, and its foundation should be good enough to build on.
POC vs prototype vs MVP: side-by-side comparison
| Factor | POC | Prototype | MVP |
|---|---|---|---|
| Main question | Can it be built? | Will users understand and want this design? | Will people use it and pay for it? |
| Risk it removes | Technical | Usability and desirability | Market and business |
| Audience | Internal team, technical stakeholders | Users, investors, internal sponsors | Real early customers |
| Working code | Yes, narrow and rough | Usually no (or front-end only) | Yes, production quality for its scope |
| Real data | Sample data | Dummy data | Real data |
| Reused afterwards | Lessons, sometimes code | Designs and flows | Code becomes the product's base |
| Typical timeline | 1-4 weeks | 2-6 weeks | 6-16 weeks |
| Indicative cost (India-based team) | $3,000-15,000 | $3,000-15,000 | $5,000-65,000 |
MVP costs follow our detailed guide to MVP development cost in India, which puts simple MVPs at ₹4-10 lakh and complex ones at ₹25-60 lakh or more. In other currencies, $15,000 is about ₹14 lakh or AED 55,000. For comparison, Clutch's app development pricing guide reports an average full app project of about $90,780 over around 11 months, which shows how much a well-scoped first step can save.
When to build a POC first
Build a POC when the idea depends on something technically uncertain:
- An AI feature whose accuracy on your data is unknown, such as extracting data from handwritten forms or summarising clinical notes.
- An integration with a legacy system, device or government API with poor documentation.
- Performance or scale assumptions: real-time tracking, video, large data volumes.
- A new technology your team has not used in production.
Define success criteria before you start, for example "extracts these 12 fields with at least 95% accuracy on 200 sample documents". A POC without a pass mark rarely ends with a clear decision.
When to build a prototype first
Build a prototype when the technology is well understood but the experience is not:
- Users have to change how they work, and you are not sure they will.
- Several user roles interact, and the flow between them is complex.
- You need investor or board approval and a demo will carry the argument.
- You are choosing between two or three different approaches to the same workflow.
Five to eight user tests on a clickable prototype usually reveal the major problems. Fixing a flow in a design tool takes hours; fixing it in code takes days.
When to go straight to an MVP
Skip to an MVP when the technology is proven and the workflow is familiar, and the open question is whether people will adopt and pay. Examples include a booking system for a type of business that already books by phone, or a B2B portal replacing a spreadsheet process. Scope it tightly around one job for one user type, and set up usage tracking from the first release so you can learn quickly.
A simple decision guide
- List your assumptions: technical, user experience, market and business.
- Mark which one, if wrong, would kill the idea.
- If it is technical, build a POC.
- If it is about whether users understand or want the workflow, build a prototype.
- If it is about adoption, retention or willingness to pay, build an MVP.
- If several are uncertain, go in order: POC, then prototype, then MVP.
- After each step, decide: continue, change direction or stop.
Three ideas, three different first steps
Idea 1: an AI tool that reads scanned purchase invoices and posts them to accounting software. The biggest risk is technical: can a model reliably extract supplier, line items, tax and totals from your real invoices, including poor scans? Start with a POC. Take 200 real invoices, define the fields and the accuracy you need, and test two or three extraction approaches over two to three weeks. If accuracy is not good enough, you have saved the cost of an MVP.
Idea 2: a care-coordination app that connects a hospital's discharge team, home nurses and patients' families. The technology is familiar, but three user roles must change how they work together, and the flow between them is not obvious. Start with a clickable prototype. Test it with a discharge coordinator, two nurses and a few family members, and refine the flow before any backend is built.
Idea 3: online booking and payments for a chain of physiotherapy clinics that currently book by phone. The technology is proven and the workflow is well understood. The open question is whether patients will book online and whether no-shows drop. Go straight to a tightly scoped MVP for one or two clinics, with usage tracking from the first day.
Each of these could become the same size of product in the end. What differs is where the uncertainty sits, and therefore what you should spend money on first.
How to scope each step so it ends with a decision
- POC: one question, a written pass mark, real or realistic sample data, a fixed time box, and a short write-up of what was learned.
- Prototype: the core flows only, tested with five to eight people from each key user group, with a list of changes made after each round.
- MVP: one job for one user type, real data, usage analytics, a small launch group and a review date to decide what happens next.
POC vs pilot, and MVP vs MMP
Two related terms cause confusion:
- Pilot: a limited deployment of a working product with a small group of real customers in real conditions, often with a defined evaluation period. A POC proves feasibility in the lab; a pilot proves value in the field. In enterprise and healthcare sales, a paid pilot is often the step between MVP and a full contract.
- MMP (minimum marketable product): the smallest version you can sell to the wider market with confidence. An MVP is for learning from early adopters; an MMP adds the polish, support, billing and reliability needed for general release.
| Term | Built for | Main goal |
|---|---|---|
| POC | Internal team | Prove feasibility |
| Prototype | Users and stakeholders | Test the experience |
| MVP | Early adopters | Learn whether it is used and valued |
| Pilot | A few real customers | Prove value in real conditions |
| MMP | The wider market | Sell with confidence |
Mistakes that waste money at this stage
- Building an MVP that is really a prototype: fake data and manual workarounds hidden behind a polished UI, then shown to investors as traction.
- Turning a POC into the product: code written to answer one question quickly is rarely a sound foundation.
- Prototypes that are too polished: high fidelity too early makes people defend the design rather than test it.
- MVPs that are not minimal: ten features instead of one job done well, launched months later.
- No success criteria: without a pass mark, every result looks like partial success.
- No usage tracking: an MVP without analytics teaches you nothing.
No-code and AI app builders can make prototypes and some MVPs faster and cheaper. Our guide to low-code and AI app builders explains where they hold up and where a custom build is needed.
How Algon approaches the first build
Algon is a Kochi-based engineering team working with founders and businesses in India, the UAE and the USA. We start with a workflow review, ideally with a few target users, and agree the one job the first release must do; if a technical assumption is shaky, we suggest a short POC first. Our MVP development work is built in short cycles you can test with prospects, on a codebase structured to be extended rather than rewritten, with your accounts and repository set up from day one. When the MVP finds traction, our product development team grows it on the same foundation.
Conclusion
A POC, a prototype and an MVP are not competing options; they are tools for different risks. Use a POC for technical uncertainty, a prototype for experience uncertainty and an MVP for market uncertainty, and only build what answers your biggest open question. Set success criteria, keep each step small, and decide after each one whether to continue. For the next stage, see how to build a SaaS product and app development cost.
Frequently asked questions
What is the difference between a POC, a prototype and an MVP?
A POC tests whether something can be built and is usually internal and disposable. A prototype shows how the product will look and work so you can test it with users, usually without a working backend. An MVP is a real, working product with the minimum features needed for early users, used to learn whether people will adopt and pay for it.
Should I build a prototype or an MVP first?
Build a prototype first if the workflow is new or complex and you are unsure users will understand or want it. Go straight to an MVP if the technology and workflow are familiar and the open question is whether people will use and pay for it.
How much does a POC, prototype and MVP cost?
With an India-based team, a POC typically costs $3,000-15,000 over one to four weeks, a clickable prototype $3,000-15,000 over two to six weeks, and an MVP $5,000-65,000 over six to sixteen weeks, depending on complexity and integrations.
What is the difference between a POC and a pilot?
A POC proves technical feasibility in a controlled setting, usually with sample data. A pilot deploys a working product with a small group of real customers in real conditions to prove its value, often before a wider rollout or full contract.
What is the difference between an MVP and an MMP?
An MVP is the smallest working product used to learn from early adopters. An MMP, or minimum marketable product, is the smallest version ready to sell to the wider market, with the reliability, support and billing that general customers expect.
Can a prototype be turned into an MVP?
The designs and flows from a prototype carry straight into an MVP, but the prototype itself usually cannot, because it has no real backend or data model. Code from a POC also needs rework before it is a sound product foundation.
