Validation has a reputation for being complicated. It is not. It is the practice of finding out whether strangers will part with money for your idea while the cost of being wrong is still small. Everything else, from survey design to market sizing, is detail around that single question.
Opinions are cheap. Commitments are not
Ask ten people whether they would buy your product and most will say yes, because saying yes costs them nothing and disagreement feels rude. Ask them to pay a deposit and the number collapses to something honest. This gap is not cynicism about human nature; it is the difference between a polite prediction and a decision with consequences.
So design tests where the answer has a cost. A preorder. A booked appointment. A signed letter of intent from a business buyer. A waiting list with a card on file. Even a small deposit changes the quality of the data.
Test the problem before the solution
Ideas fail more often because the problem was minor than because the product was poor. Spend the first conversations on the problem. What does the person do today? How long does it take? What does it cost them in money, time or irritation? What have they already tried, and why did they stop?
If the person cannot describe the problem without your prompting, you are probably solving something you find interesting rather than something they feel. That is useful information, and it arrived before you built anything.
Four tests, ranked by cost
Start at the top and only move down when the cheaper test gives you a clear yes.
- Conversations. Fifteen minutes with ten people who match your customer description. Free, fast, easy to bias, so listen more than you talk.
- A one-page offer. A simple page that states the price, what is included and how to buy. Share it in the places your customers already gather. Measure enquiries, not visits.
- A presale. Ask for money with a clear refund policy. This is the strongest cheap signal available.
- A small paid pilot. Advertise a limited run to a narrow audience. Costs money, but tells you what acquisition actually costs.
Read the results honestly
Set the pass mark before the test, not after. Something like: fifteen enquiries and three presales from a hundred targeted visitors. Without a threshold agreed in advance, every result becomes a story you can tell yourself. With one, the answer is uncomfortable but clear.
A test you cannot fail is not a test. If every possible outcome leads to the same decision, you were never validating, only rehearsing.
Watch for the near-miss trap. People who say they will buy next quarter, once the website is better, once their budget resets. Polite deferrals are a no wearing a friendly face. Count them separately and do not let them inflate the result.
What validation cannot tell you
Demand is necessary, not sufficient. A validated idea can still fail on delivery, cash flow or your own stamina. Validation shortens the list of things that might be wrong; it does not empty it. Be equally honest about whether you want to run this business on a wet Tuesday in February, not just whether the market wants it.
Nor does it replace a first customer. One paying stranger teaches more about pricing, delivery and support than twenty interviews, so get to that person as quickly as the test allows. It also cannot rescue a weak offer. If three customers buy and twelve hesitate, the answer is usually clarity and price, not more advertising. Rewrite the offer in the customer's words, remove one feature, and test again with fresh people.
Validation checklist
- A one-sentence customer description specific enough to find ten of them this week
- Evidence of the problem in the customer's own language, not yours
- A pass mark written down before the test begins
- At least one test that required a real commitment, not an opinion
- A note of what you would have to see to walk away
- Total spend capped at an amount you can lose without changing your plans
Then decide. Build small, sell first, and keep the test running for the first few months of trading. Validation is not a gate you pass once. It is a habit of checking the ground before each step, and it gets cheaper every time you do it.
