An idea is validated when someone pays, or clearly commits to pay. Compliments, likes and "I would use that" are not validation. Everything before money is a guess.
Step 1: write the idea as a sentence
If you cannot say it in one sentence, you cannot test it.
For [a specific customer], who [has this problem], I offer [this solution] for [this price].
Example: For dog owners who work long days, I offer a midday walk for 15 dollars.
Each part of that sentence is an assumption. Validation means testing each one.
Step 2: talk to real potential customers
Find ten to twenty people who match your customer. Ask about their life, not your idea. People are kind about ideas and honest about their own habits.
- Tell me about the last time you had this problem.
- What did you do about it?
- What did that cost you, in money or time?
- What have you tried that did not work?
Do not pitch until the end. Listen for a problem they already spend money or time on. That is the strongest signal.
- Would you use this?
- Do you like my idea?
- How much would you pay for this?
These questions get polite answers, not true ones. Ask about what they did, not what they would do.
Step 3: check what people do today
Look at how your customers solve the problem now. Competitors are good news. They prove people pay. Your job is to find what the current options do badly: too expensive, too slow, too complex, or made for someone else.
Search forums, review sites and Reddit for complaints about existing options. Those complaints are your opening.
Step 4: ask for a small commitment
Now make an offer. Not a finished product. A real offer.
- A pre-order or deposit.
- A paid first session or pilot.
- A signed letter of intent, for business customers.
- At the weakest, a waitlist with a clear promise of what they will get.
I am starting a midday dog-walking service in your area, from 1 November. The first five customers get their first week at half price. Would you like one of those places? A 20 dollar deposit holds it.
If people pay, you have your answer. If they say "maybe later", ask what would make it a yes now.
Step 5: decide what the evidence says
After a few weeks you should know one of three things.
- People pay. Start, and keep it small until it works.
- People have the problem, but not at this price or in this form. Change the offer and test again.
- People do not have the problem badly enough. Drop it, and be glad it was cheap to learn.
Use AI, but not to fake the answer
AI is useful for research: who the competitors are, what people complain about, which questions to ask. It cannot replace the conversations. A model will happily tell you an idea is great. Real people with real money are the only test.
