In the pack: ChatGPT, Claude & Gemini Prompts to Write a Business Plan
Turn Customer Interview Notes Into Plan-Ready Evidence
Prompt
What I was testing: {{KEY_ASSUMPTIONS}}
Number of interviews and who they were: {{INTERVIEW_SAMPLE}}
My raw notes, anonymized: {{INTERVIEW_NOTES}}
Do this:
1. For each assumption, count how many interviews supported it, contradicted it or didn't address it. Quote the short phrase from my notes behind each count.
2. List the recurring pains, current spending and buying triggers people mentioned, with counts.
3. Pull out any concrete commitments: pre-orders, deposits, sign-ups, introductions.
4. Point out where the sample is biased (friends, one location, one type of customer) and how that limits what I can claim.
5. Write a 150-word 'Customer validation' paragraph for the plan that states the numbers plainly, for example '9 of 14 owners interviewed said...'.
6. List the assumptions still unproven and what to test next.
Rules: count only what's in my notes. Don't turn 'sounds interesting' into demand. Don't convert small samples into percentages that imply more precision than they have.
