How to Build an MVP: A Practical Guide

20 March 2026

An MVP — Minimum Viable Product — is the simplest version of your product that lets you test whether real people will actually use it. Not a prototype. Not a mockup. A working product with just enough features to be useful.

We've built over 8 MVPs, both for clients and for ourselves. Products like Shrnk.ly (built in one month), Moonlight Monitor, and ClassyDoc all started as MVPs. Here's the process we've refined through those builds.

Step 1: Define the Core Problem

Before you write any code, write down the single problem your product solves. Not three problems. Not a platform. One specific problem for one specific type of person.

Bad: "A platform for businesses to manage their operations." Good: "Freelance designers can't easily track which clients owe them money."

If you can't describe the problem in one sentence, you're not ready to build yet. Keep refining until you can.

Step 2: Identify the Must-Have Features

List every feature you think the product needs. Then cut that list in half. Then cut it in half again. What's left is your MVP scope.

For each feature, ask: can a user get value from the product without this? If yes, it's not in the MVP. User accounts, settings pages, admin dashboards, analytics — most of these can wait.

When we built Shrnk.ly, the MVP had three features: shorten a URL, track clicks, and generate a QR code. That was it. No user accounts, no team features, no integrations. And it was useful from day one.

Step 3: Pick Your Tech Stack

Choose technologies you know. An MVP is not the time to learn a new framework. Use what your team is productive with, and pick tools that let you move fast.

For web applications, we typically use Next.js or React with a Node.js backend. For mobile apps, Flutter or React Native. For simple APIs, a straightforward Node.js or Rails setup.

The tech stack matters less than you think at the MVP stage. What matters is speed to market.

Step 4: Set a Hard Deadline

An MVP without a deadline becomes a never-ending project. Set a timeframe — 2 weeks, 1 month, 3 months maximum — and commit to shipping by that date.

The deadline forces decisions. Instead of debating whether to build feature X, you ask: can we ship this by the deadline with feature X included? If not, it's out.

Every product we've built had a fixed timeline. That constraint is what makes the MVP process work.

Step 5: Build, Don't Perfect

Your MVP will have rough edges. That's fine. The goal isn't a polished product — it's a product that works well enough to test your assumptions.

Focus on the core user flow. If your product helps people shorten URLs, make sure that flow is smooth and reliable. Everything else can be basic.

Avoid: custom design systems, complex authentication, extensive error handling for edge cases, performance optimisation, and comprehensive documentation. These all matter later. They don't matter for an MVP.

Step 6: Get It In Front of Real Users

This is the step most people skip. They build the MVP, admire it, and then start adding features instead of testing it with real people.

Find 5-10 people who have the problem you're solving. Give them the product. Watch them use it. Don't explain how it works — see if they can figure it out. Listen to what they say, but pay more attention to what they do.

When we put ClassyDoc in front of Torqn, they used it for spam detection — a use case we hadn't prioritised. That real-world feedback shaped the entire product direction.

Common MVP Mistakes

Building too much before testing. If your MVP takes more than 3 months, you're building too much. Cut scope.

Asking people if they'd use it instead of building it and seeing if they actually do. Hypothetical interest is worthless. Real usage is everything.

Choosing unfamiliar technology. Your MVP will be slow enough without a learning curve on top.

Skipping the ugly middle. Every product goes through a phase where it works but doesn't look great. That's normal. Ship it anyway.

Not setting success criteria. Before you launch, define what success looks like. Is it 10 users? 50 signups? One paying customer? Without a target, you'll never know if the MVP worked.

What Comes After the MVP

If real users engage with your MVP, you've validated the idea. Now you can invest in polish, additional features, and scaling. If they don't, you've saved months of development time and can pivot or move on.

Either way, you win. That's the point of an MVP.
