How to build an MVP
Decide what belongs in a first version, what to leave out, and how to check whether the result taught you anything.

An MVP is the smallest product that lets you test a meaningful assumption with real users. It is not a cheaper version of the full vision. It is a focused experiment.
What is an MVP?
An MVP should complete one important job for one customer. If they can finish that job, you can learn whether the product is worth expanding.
What to include
- The core workflow that delivers the promised outcome.
- A way to sign in or identify the user if the job requires it.
- A way to see the result (a dashboard, email, export, or live URL).
- Enough reliability that testers are not blocked by obvious breakage.
What to leave out
- Admin tools nobody asked for.
- Every role, every integration, and every theme.
- Growth features before anyone uses the core job.
- Perfect visual polish that delays learning.
How to validate the MVP
- Give it to a small group that already has the problem.
- Watch them complete the core job without you in the room.
- Ask what they would pay for, not what extra buttons they want.
- Keep a list of friction. Fix only what blocked the job.
Common mistakes
- Building a demo that cannot be used without you.
- Calling a slide deck an MVP.
- Adding features whenever a single tester asks.
- Never defining the assumption you are testing.
Frequently asked questions
- How long should an MVP take?
- As short as you can make it while still testing the real job. Timeboxes help; feature lists rarely do.
- Should it be full-stack?
- If the job needs accounts, data, and a live URL, yes — those are part of the job, not extras. Decorative extras are not.
