What an MVP Actually Is (And Isn't)
"MVP" gets used to mean "a smaller, cheaper version of the real product." That's wrong, and it's an expensive mistake — because a smaller version of the wrong product is still the wrong product, just cheaper to be wrong about.
The actual definition
An MVP is the smallest thing you can put in front of a real person that tests your riskiest assumption — the one thing that, if false, means the whole idea doesn't work. It is a learning tool first, not a product first.
Airbnb's MVP wasn't a stripped-down booking platform. It was three air mattresses and a listing. It tested exactly one risky assumption — will strangers pay to sleep in another stranger's home — and nothing else. No payment processing, no search, no reviews. Those could all be fake, manual, or missing entirely, because none of them were the risky assumption.
How to find your riskiest assumption
Ask: "What has to be true for this to work, that I'm least sure about?" Usually it's not a technical question ("can I build this?") — it's a human one ("will anyone actually want this enough to change their behavior or pay for it?"). Technical risk is usually solvable with enough time. Human/market risk is the one that kills startups, per the CB Insights data from the first lesson this week.
Common MVP mistakes
- Building the full feature set, just "lite." If it takes more than a couple weeks and real engineering effort, it's probably not minimal enough.
- Testing the wrong assumption. Spending a month perfecting a signup flow when you haven't confirmed anyone wants the underlying thing at all.
- Skipping the test and just launching. An MVP without real users giving real feedback isn't an MVP — it's just a small, unvalidated product.
What a good MVP can look like
It doesn't have to be software. A landing page collecting emails, a manual service you deliver by hand (a "concierge MVP"), a spreadsheet, or — like Airbnb — literally just showing up and doing the thing yourself for the first few customers. The bar isn't "impressive." The bar is "tells you the truth, fast, cheaply."
