MVP vs Prototype: What to Build First and Why

The terms MVP and prototype get used interchangeably, but they're fundamentally different tools. Using the wrong one wastes time. Here's how to choose.

What's a Prototype?

A prototype demonstrates a concept. It doesn't need to work — it needs to communicate. Prototypes answer the question: 'Does this idea make sense?'

• Can be just mockups or wireframes
• Doesn't need real functionality
• Used to validate concepts with potential users
• Takes hours to days to create
• Goal: Get feedback before writing code

What's an MVP?

An MVP (Minimum Viable Product) is a real product with minimal features. It actually works. MVPs answer the question: 'Will people use and pay for this?'

• Functional product that solves the core problem
• Can be ugly but must work
• Used to validate business viability
• Takes days to weeks to build
• Goal: Get real users and real feedback

When to Build a Prototype First

• You're not sure the problem is real
• The solution requires explaining
• Building would take months
• You want investor feedback before building
• The core UX is complex and needs validation

When to Skip to MVP

• The problem is obvious and validated
• You can build a working version in a weekend
• The core value is in the functionality, not the concept
• You have technical skills ready to deploy
• You need real usage data, not opinions

Types of Prototypes

Paper Prototypes

Sketches on paper. Fast, free, easy to change. Good for very early concept validation.

Clickable Mockups

Figma or Framer prototypes that simulate the product. Users can 'click through' but nothing works behind the scenes.

Wizard of Oz

Looks automated but has a human behind the scenes. User thinks they're using a product; you're actually doing the work manually.

What Makes a Good MVP

• Solves one problem completely
• Can be used without explanation
• Delivers value immediately
• Gathers feedback and usage data
• Can be built in 2-4 weeks

Common Mistakes

• Building features before validating the problem (prototype first!)
• Making the MVP too complex (it's Minimum for a reason)
• Never launching because it's not 'ready'
• Confusing prototype feedback with MVP validation
• Skipping both and building full product (dangerous)

The Ideal Flow

1. Identify problem → 2. Prototype to validate concept → 3. MVP to validate business → 4. Iterate based on real data
