AI is a good thinking partner for a business idea. It is a poor judge of whether anyone will pay for it.
Direct answer
AI can help you challenge your idea, list your assumptions, draft customer interview questions and plan cheap tests, but it cannot validate demand. Validation needs real evidence from real people, such as conversations, pre-orders and small paid trials. Use AI to prepare, then go and talk to customers.
What AI is good for
- Challenging you: "Act as a sceptical investor. What are the weakest points?"
- Listing assumptions: "What must be true for this to work?"
- Interview questions: "Write ten non-leading questions to ask people about how they handle this today."
- Test ideas: "Suggest three cheap ways to test demand within a week."
- Drafting: a landing page, an outreach message.
Prompts to try
My idea: [describe it]. Who is the most likely first customer? List the five riskiest assumptions and a cheap test for each.
Act as a potential customer who has this problem. I will interview you. Stay in character, and point out when my questions are leading.
What AI can't do
- Know whether real people will pay
- Replace conversations with customers
- Give reliable market sizes. AI can make up figures.
- Understand your local market without your input
A good combination
- Use AI to sharpen the idea and questions.
- Talk to at least ten real potential customers. See how to validate a business idea.
- Run a cheap test.
- Use AI to help summarise what you learned, checking it against your notes.
