Quick verdict
Build a prototype to test your concept, validate the UX, and pitch investors before writing real code. Build an MVP to launch a working product, acquire real users, and validate whether people will actually pay for your solution.
Key differences
| Dimension | Prototype | MVP |
|---|---|---|
| Purpose | Test concept & design | Validate market demand |
| Functionality | Simulated (no real backend) | Working core features |
| Audience | Internal team, stakeholders, investors | Real customers and users |
| Stage | Pre-product (alpha) | Product launch (beta) |
| Timeline | 1–4 weeks | 2–4 months |
| Cost | $5K–$25K | $25K–$100K+ |
| Revenue potential | None (it’s a demo) | Yes (real transactions possible) |
| Feedback type | Design & UX feedback | Market validation & usage data |
| What you learn | Is the experience right? | Will people pay for this? |
| Next step | Build the MVP | Iterate and scale |
What is a prototype?
A prototype is a visual representation of your product—it shows what the experience looks like and how users interact with it, but it doesn’t have real functionality behind the screens. Think of it as an interactive mockup. You can click through screens, see the layout, and test the user flow, but there’s no real database, no real payments, and no real backend logic.
Prototypes are built using tools like Figma, Framer, or simple clickable wireframes. They’re fast and cheap to create—typically 1–4 weeks and $5K–$25K. Their primary purpose is to validate the concept and user experience before investing in real development. They’re also powerful pitch tools for investors and stakeholders.
What is an MVP?
A Minimum Viable Product is the simplest working version of your product that solves the core problem for real users. Unlike a prototype, an MVP has a functional backend, processes real data, and can accept real transactions. It’s not a demo—it’s a product, just a deliberately minimal one.
The key word is “viable”—an MVP must deliver enough value that real users will use it (and ideally pay for it). This means real code, real infrastructure, and real deployment. Typical timeline is 2–4 months, costing $25K–$100K+ depending on complexity. The primary purpose is to validate market demand by getting the product into real users’ hands and measuring their behavior.
When to build each
Here’s the decision framework for founders:
- Build a prototype first if: you’re still exploring the concept, need to pitch investors, want to test multiple design directions, or aren’t sure about the user flow. A prototype lets you fail fast and cheap before committing to development.
- Build an MVP first if: you’ve already validated the concept (through customer interviews, landing page tests, or a prototype), have a clear understanding of the core feature, and need to prove market demand with real users and real data.
- Build both (sequentially) if: you have the time and budget. The ideal path is: prototype first to validate UX and get stakeholder buy-in, then MVP to validate the market. This de-risks the larger investment in MVP development.
- Skip straight to MVP if: you’re solving a well-understood problem (e.g., a better version of an existing tool), have deep domain expertise, and time-to-market is critical. Sometimes speed matters more than design perfection.
Frequently asked questions
Not directly. A prototype is typically a design artifact (Figma, clickable mockup) with no real code. An MVP requires real development—backend, database, deployment. However, a prototype’s designs and user flows directly inform what gets built in the MVP, saving significant development time.
For most startups, $25K–$100K is the typical range for an initial MVP, depending on complexity. The key is ruthless prioritization—build only the core feature that validates your hypothesis. You can always add features after you’ve proven demand.
Not always, but it helps enormously. A clickable prototype makes your pitch tangible and shows investors you’ve thought through the user experience. Pre-seed rounds can sometimes be raised with just a pitch deck, but a prototype significantly increases your chances.
