A promising idea is not the same as a proven market. Validation means collecting evidence that people have the problem and will act to solve it.
Write a falsifiable customer hypothesis
State who needs the product, what makes the problem urgent, and how they currently deal with it. Example: independent contractors with five or more subcontractors struggle to keep certificates of insurance current. A hypothesis should be specific enough that real interviews can prove it wrong.
Interview behavior, not compliments
Avoid asking “Would you buy my idea?” People naturally want to be encouraging. Instead ask: “Tell me about the last time this happened.” “What did it cost you?” “What did you try?” “Who decides on purchases?” Details about prior behavior are more informative than friendly predictions.
Map existing alternatives
Competitors are useful evidence that a market exists. Look at pricing, reviews, feature complaints, service levels, and who appears underserved. Your goal is not necessarily to invent a new category; it may be to serve a narrower customer much better.
Test a real offer
Try a landing page with a meaningful call to action, a paid pilot, a preorder with transparent terms, or a manual service that simulates the proposed software. Be clear about what exists today and what you have not built.
Define a go/no-go threshold
Before testing, choose evidence that would make you continue: for example, several customers willing to pay a stated price, a strong pattern of repeat pain, and a delivery process you can afford. Avoid changing the rules after weak results simply because you love the idea.
Run the math
Estimate price, variable fulfillment cost, acquisition cost, support time, refunds, and recurring overhead. Revenue is not the same as contribution margin. If each order loses money before paying you, increasing volume makes the problem bigger.
The cheapest mistake is a small test that tells you not to build the wrong thing.
