Business Idea Validation Checklist (Free, 27 Questions)

This checklist is 27 questions across seven groups: the problem, the customer, the market, competition, the money, dependencies, and proof. Answer them in order, in writing, with evidence rather than feelings. Most ideas die around question 12, and that is the checklist working. The ones that survive every group have earned the right to a real test.

How to use this

Write the answers down. A question answered in your head gets the benefit of every doubt; a question answered on paper does not. And wherever a question asks for evidence, "I believe so" counts as no. That rule does most of the checklist''s work.

The problem

1. Can you state the problem in one sentence without using the word "better"?
2. Can you name the moment the problem hurts: the trigger that makes someone go looking?
3. Is the problem frequent or painful enough that people actively try to solve it today?
4. What do people currently do about it, and have you watched or read about anyone actually doing that workaround?
5. Can you find strangers complaining about this problem in public, in their own words, right now?

The customer

1. Who is the specific first customer: a role, a situation, a budget, not "everyone"?
2. Do you know where that person gathers, online or off, and can you name three places?
3. Can you reach them without paying more than a few dollars per conversation?
4. Have ten of them told you, unprompted, that this problem matters to them?
5. Does the person with the problem control the money to fix it?

The market

1. Do people search for solutions to this? What does the search data say, in actual numbers?
2. Are there buying-intent searches, phrases with best, vs, alternative, pricing, attached to this problem? (Here is how to check.)
3. Is the market growing, shrinking, or stable, and what evidence told you so?
4. How many potential customers are there, roughly, and can you show the arithmetic?

Competition

1. Who are the three closest competitors or substitutes, including doing nothing?
2. What do their unhappy customers complain about, verbatim? (Here is how to collect it.)
3. What do you do that they structurally cannot, not just have not yet?
4. If a well-funded competitor copied you next month, what exactly would stop them?

The money

1. What will you charge, and is there evidence anyone pays that much for this class of solution?
2. What will it cost to get one paying customer, and does the price survive that cost?
3. Is there a second purchase, renewal, or expansion, or is every sale the last one?
4. Can the business reach meaningful revenue with a realistic number of customers, or does it need millions of users to matter?

Dependencies

1. List every company, platform, API, or regulator that must say yes. How many are there?
2. Does any one of them also compete with you, or sell to your customers directly?
3. What happens to the business if your biggest dependency changes its terms next year? (If you have not thought about this, read platform risk first.)

Proof

1. What have strangers already done, not said: clicks, signups, deposits, replies?
2. What is the cheapest test that would prove the riskiest assumption, and why have you not run it yet?

Scoring yourself honestly

Do not count the yes answers. Count the evidence. An idea with twenty yeses backed by belief is weaker than one with twelve backed by receipts.

If questions 5, 9, 11, 19, or 26 came back empty, stop and fix that gap before anything else. Those five are the load-bearing ones: public pain, reachable customers, search demand, proof of price, and real behavior. Everything else is commentary.

And when the checklist says the idea is shakier than you hoped, that is a win you bought for the price of honesty. The free Reality Check runs this same logic against live market evidence and attaches the receipts. Cheaper than learning it from six months of building.

Frequently asked questions

What questions should I ask to validate a business idea?

Twenty-seven, in seven groups: five on the problem, five on the customer, four on the market, four on competition, four on the money, three on dependencies, and two on proof. The load-bearing ones are public pain, reachable customers, search demand, proof of price, and real behavior from strangers.

Is there a free business idea validation checklist?

Yes, this one. Twenty-seven questions, no signup. Answer in writing and count evidence rather than yeses. Wherever a question asks for proof, "I believe so" counts as no.

How many checklist questions should an idea pass?

Do not count passes, count evidence. An idea with twenty confident yeses and no receipts is weaker than one with twelve yeses backed by search data, complaints, and a deposit. The five load-bearing questions matter more than the other twenty-two combined.

What do I do if my idea fails the checklist?

Fix the specific gap it exposed, or kill the idea while it is still cheap. Public pain can be searched for, customers can be hunted down, price can be tested with a preorder page. If the failure is structural, stopping early is the outcome the checklist exists to produce.
