POC vs. Prototype vs. MVP: The difference every startup founder should know

‍

Every startup begins with an idea. Some ideas sound brilliant in your head, but here’s the truth: most ideas fail once they hit the market. According to CB Insights, 35% of startups fail because there’s no market need, and another 20% due to competition. The key to avoiding this pitfall is validating your idea before you sink months or years into building it. For entrepreneurs, three terms often float around: Proof of Concept (PoC), Prototype, and Minimum Viable Product (MVP). They might sound similar, but they serve different purposes.

Understanding the difference can save you time, money, and frustration—and may determine whether your startup thrives or stalls. Let’s break them down and see how each one fits into the journey of turning your idea into a real business.

‍

POC, Prototype, and MVP in a nutshell

‍

• A Proof of Concept (PoC) is about proving whether an idea is technically possible.
• A Prototype is about showing what the product will look and feel like.
• An MVP is about launching the simplest working version to real users.

These three steps are not always sequential, but together they help you validate an idea, secure funding, and build something people actually want.

‍

‍

What is a PoC?

‍

A Proof of Concept is a small project created to test whether an idea is technically viable. Think of it as dipping your toes in the water before diving in. Instead of spending months coding or designing, you build a small-scale model to answer a single question: will this idea actually work? PoCs are usually internal and rarely shared with end users. They often lack proper design, usability, or even clean code. The point isn’t to make it pretty—it’s to confirm that your idea can live outside your imagination.

Main focus: Technology feasibility

Question to answer: Can this idea work in practice?

Key deliverables: Demo, feasibility report, or simulation

‍

Why choose a PoC?

• To test whether a new technology works as expected
• To explore uncharted markets or ideas
• To gain confidence before pitching to investors
• To uncover risks early in the journey

‍

Use cases for PoCs

• Technology validation: For example, testing if OpenAI’s API can support your chatbot idea.
• Market research: Running small experiments with a few target users.
• Investor buy-in: Showing a demo to backers before raising funds.

‍

Famous PoC examples

• Dropbox: Before building their platform, Dropbox shared a simple video showing how file-sharing could work. That explainer video alone was enough to validate user interest.
• Amazon Go: Before launching cashier-less stores, Amazon tested the system internally with employees, proving the idea was technically possible.

‍

What is a Prototype?

‍

A prototype is your product’s visual and interactive draft. It doesn’t need to function fully, but it should give stakeholders and users a sense of the look, flow, and interactions. A prototype answers the “what will this look like?” question. Prototypes range from low-fidelity sketches on paper to high-fidelity clickable designs created with tools like Figma or InVision.

Main focus: Design and user experience

Question to answer: How will the product look and feel?

Key deliverables: Wireframes, mockups, interactive designs

‍

Why choose a prototype?

• To visualize ideas before writing a single line of code
• To align your team and investors around a shared vision
• To test usability and gather early feedback
• To save money by spotting design flaws before development

‍

Use cases for prototypes

• User testing: Showing a clickable demo to early adopters.
• Stakeholder alignment: Communicating product vision clearly.
• Feature prioritization: Deciding which features should make it into the first build.

‍

Famous prototype examples

• Facebook: Mark Zuckerberg’s early “Thefacebook” was a simple prototype tested at Harvard before scaling.
• Trello: Started with a card-and-board concept shown to a small group of users. Feedback from that prototype shaped what Trello is today.

‍

What is an MVP?

‍

A Minimum Viable Product (MVP) is the first real version of your product released to early users. It has just enough features to be usable while leaving room for improvements. Unlike a prototype or PoC, an MVP is out in the world, solving real problems and collecting real data. The goal is not perfection—it’s learning. You build, launch, measure, and iterate.

Main focus: Real-world functionality

Question to answer: Will people use and pay for this product?

Key deliverables: A simplified but working product

‍

Why choose an MVP?

• To validate assumptions with actual users
• To enter the market faster and cheaper
• To attract investors with proof of traction
• To pivot quickly if needed

‍

Use cases for MVPs

• Market testing: Seeing if your idea resonates with your target audience.
• Funding: Demonstrating traction to raise capital.
• Iterative development: Improving based on user feedback.

‍

Famous MVP examples

• Instagram: Began as “Burbn,” with multiple features, but pivoted after users showed interest mainly in photo-sharing.
• Slack: Evolved from “Glitch,” a messaging tool for game developers, into one of the most widely used team collaboration platforms.

‍

PoC vs. Prototype vs. MVP: What’s the difference?

‍

The three serve different purposes:

• PoC proves feasibility.
• Prototype explores usability and design.
• MVP tests demand and functionality.

They often complement each other. A startup might begin with a PoC to confirm technology, then design a prototype to align vision, and finally release an MVP to validate the market. However, depending on resources, you may skip one step or merge processes.

How to choose the right approach for your startup

‍

Step 1: Define your goal

• Choose a PoC if you need to prove the idea works technically.
• Choose a prototype if you want to explore design and gather feedback.
• Choose an MVP if you’re ready to test with real users.

‍

Step 2: Assess your resources

• PoC: Low cost, short time investment.
• Prototype: Moderate cost, requires design skills.
• MVP: Higher investment, but real-world returns.

‍

Step 3: Evaluate your market

• PoC: Best when exploring untested ideas.
• Prototype: Useful when refining usability.
• MVP: Critical when demand is clear and you’re ready to scale.

‍

Step 4: Plan your development

• PoC: Focus on technical demos or simulations.
• Prototype: Create clickable designs with tools like Sketch.
• MVP: Build a working product, even if minimal, and launch it.

‍

Step 5: Gather feedback

• PoC: Share with stakeholders for feasibility validation.
• Prototype: Test usability with potential users.
• MVP: Launch, measure, and iterate based on real-world data.

‍

Final words

‍

Building a successful product isn’t about jumping straight into full development—it’s about reducing risk step by step. PoC, Prototype, and MVP are three strategies that help you validate your idea and make smarter decisions along the way.

• A PoC helps you answer, “Can this even work?”
• A prototype helps you answer, “What will this look like?”
• An MVP helps you answer, “Will people actually use it?”

As a founder, your challenge is to choose the right approach for your stage, resources, and goals. Sometimes you’ll need all three; other times, just one will do. But skipping validation altogether? That’s the fastest road to failure. Start small, validate often, and let real-world data guide you.
