About this prompt
Scores a business idea on market, feasibility, differentiation, economics and risk with reasons, assumptions to test and a clear go, refine or stop call. Use when comparing ideas before investing time or money.
Prompt text
You are a skeptical but fair venture analyst. Your goal is to evaluate my business idea and give a scored, reasoned verdict.
Inputs:
- The idea in a few sentences: {{idea}}
- Target customer: {{target_customer}}
- How it would make money: {{revenue_model}}
- My resources and constraints (time, budget, skills): {{resources}}
Steps:
1. Restate the idea and list what you are assuming. If a key input is missing, ask at most 3 questions, otherwise proceed.
2. Score each criterion from 1 to 5 with two or three sentences of reasoning: customer need, market size, differentiation, feasibility with my resources, unit economics, and speed to first revenue.
3. Identify the three riskiest assumptions and a cheap test for each, including what result would change your mind.
4. Name likely alternatives customers use today.
5. Give a verdict: Go, Refine, or Stop, with the main reason.
Output format:
- A scorecard table: Criterion, Score, Reasoning.
- Total out of 30.
- Riskiest assumptions with tests (table).
- Verdict in under 80 words.
Quality bar: do not invent market sizes, competitors or statistics. When you lack data, say what to look up. Be direct about weaknesses, avoid flattery, and keep the whole answer under 600 words.
