Market validation checklist: 12 points to review in 2027

Work this in order and stop at the first failure. That is the whole instruction, and it is what makes a checklist worth anything: the items are sequenced so a later one cannot rescue an earlier one.

Most market checks get run in the opposite order, starting with the industry size because it is the easiest to look up and the most flattering. It is also the item that decides the least.

What to take away

• Order matters more than completeness. A reachable audience with a small total is a business; an enormous total you cannot reach is not.
• Stop at the first failure and fix it before continuing. Passing later gates does not compensate.
• Every gate has a version you can run this week without building anything.

Gate 1: the group has a trace in the world

The check. Describe who has this problem so a stranger could find twenty of them by Friday. The description must name something visible: a role title people write on their profiles, a license, a piece of software they must run, a rule that applies to them, a place they are, an event they attend.

This week. Actually build the list of twenty. Not an estimate of how many exist. Twenty names or twenty identifiable handles.

Stop if the description is a mood rather than a group. Small business owners and busy professionals are moods. Everything downstream assumes you can find these people, and if you cannot list twenty, you cannot.

Gate 2: you can reach them through a route anyone could use

The check. Name three places where at least twenty of them are gathered right now, and what it would cost to put one message in front of that group.

This week. Try one of the three. Contact a small batch, count the replies, and count what the attempt cost you in time and money.

Stop if every route runs through people you already know. That is an address book rather than a market, and the difference does not appear until you try to grow.

Gate 3: the problem recurs and someone acts on it

The check. Two numbers, not one: how often the problem happens, and how often anybody does anything about it. The gap between them is where most painful but unbuyable ideas live.

This week. Ask five people to recall the last occurrence with a date, and whether they did anything about it. Count the ones who acted.

Stop if the problem is severe and rare, or frequent and tolerated. Both produce sympathy and no purchase. Problem discovery covers the tests that separate a problem from an annoyance.

Gate 4: money is already moving

The check. Find evidence that somebody spends on this problem in a clumsier form. Hiring for the task, an agency or freelancer selling the manual version, an adjacent subscription the budget comes out of, or a workaround costing measurable hours.

This week. Look at job listings, at service providers, and at what your prospective customers already pay for. One afternoon. For the wider picture of how many businesses of a given kind exist and how many survive, the federal series on business births, deaths and survival is free and dated, which is more than most industry figures manage.

Stop if you find nothing anywhere. Not because it is fatal, but because the burden of proof has shifted onto you, and you should know that before you spend.

Gate 5: you have met the person who can authorize a purchase

The check. Not the person who feels the problem. The one who releases money, and the one who can block it without any formal authority at all.

This week. Ask everyone you speak to who signed off the last comparable purchase, and get one conversation with such a person.

Stop if everyone you have spoken to would have to ask somebody else. You have validated a user and not a buyer, and those fail in opposite ways.

Gate 6: you know the trigger

The check. The event that makes someone look for a change: a failure, a new hire, an audit, a renewal, a growth threshold, a rule change. Purchases in established categories follow triggers.

This week. For anyone who did act, ask what happened immediately before. The answer is usually specific and repeatable.

Stop if the honest answer is that people would switch when they get around to it. That describes nobody switching, and it makes your acquisition cost unknowable.

Gate 7: the bottom-up number holds up

The check. One customer pays what, how often, and how many can you reach in a year through the channel from gate two. Multiply. Keep every input visible as a separate assumption rather than folding them into a total.

This week. Write the chain out and mark which single assumption the result depends on most. That is what to test next. The SBA's outline of market research and competitive analysis lists the public sources worth using for the inputs you cannot count yourself.

Stop if the number only works when two or more inputs sit at the optimistic end at once. That is not a forecast. It is a wish with arithmetic attached.

Gate 8: you have written what would change your mind

The check. One sentence naming what you would have to observe to abandon or redirect this, with a date attached.

This week. Write it, and give it to someone with nothing at stake.

Stop if you cannot write it. A market memo with no falsifying condition is a pitch, and the audience is you.

What passing means

Eight passes means the boundary is drawn: who, reachable how, at what cost, buying when, deciding through whom. It does not tell you what to sell inside that boundary or at what price. Those need a specific offer and a specific refusal, which is what pricing validation and the rest of the market validation work are for.

Common questions

What if I fail gate two but pass everything else?

Then you have a distribution problem, which is the most common fatal one and the one that looks from the inside exactly like being wrong about the product. Work on channels before anything else, and treat every later gate as provisional until reach is settled.

Can I run these out of order?

Gates three to six are conversations and can overlap. One and two must come first, because the rest of the evidence is worthless if it came from an unrepeatable sample. Gate eight is last by definition.

How do I check gate four without a budget?

All of it is public. Listings, providers who do the manual version, and what similar organizations already subscribe to are visible for free, and what rivals emphasize tells you what they think buyers pay for: see competitor validation.

Does passing mean the idea will work?

No. It means the failure modes you can check cheaply have been checked, and the remaining risk sits in delivery, price and execution. That is a better position than most ideas reach, and it is not a prediction. Whether you can get honest answers at gates three to six is settled by customer interviews.
