MVP vs Prototype vs Proof of Concept: What's the Difference?
Three ways to test an idea before building the full product, what each one proves, and which to choose for your situation.
Founders often hear these three terms used interchangeably. They are different tools that answer different questions, and choosing the right one saves time and money.
Proof of concept: can it be done?
A proof of concept (PoC) tests whether something is technically feasible. It is usually small, rough, and never shown to customers. For example: can AI extract the right fields from our invoices accurately enough?
- Answers: is this technically possible?
- Audience: your team and decision-makers
- Typical output: a test, a report, and a recommendation
Prototype: will people understand and want it?
A prototype shows how the product will look and work, often as clickable designs without real functionality. It lets you test the experience with real users quickly and cheaply.
- Answers: is this the right experience?
- Audience: potential users, stakeholders, and investors
- Typical output: interactive designs and user feedback
Minimum viable product: will people use and pay for it?
An MVP is a real, working product with the smallest set of features that delivers value. Real customers use it, which means it must be reliable and secure.
- Answers: does this create enough value that people adopt it?
- Audience: early customers
- Typical output: a launched product and usage data
Which do you need?
- Uncertain technology: start with a proof of concept.
- Uncertain experience or demand: start with a prototype.
- Confident in both: build an MVP.
Many products go through all three in order, each step reducing risk before a larger investment.
Each stage should answer one question as cheaply as possible.
MOKRIN helps founders choose the right first step and builds proofs of concept, clickable prototypes, and MVPs, all with clear goals agreed upfront.
