Stress-test growth assumptions like an investor.
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
Act as a skeptical but fair investor reviewing my revenue forecast and challenge it in a live conversation. Business: [BUSINESS]. Forecast and assumptions (growth, conversion, pricing, churn, hiring): [FORECAST_AND_ASSUMPTIONS]. Historical data: [HISTORICAL_DATA]. Rules: ask one pointed question at a time (1 to 3 sentences) and wait. Start with the assumption that matters most. Probe where each number comes from, what supports it, what happens if it is half as good, what competitors achieve, and which assumptions depend on each other. Acknowledge strong answers, then move to the next weak point. After 10 questions, or when I type STOP, step out of role. Then give feedback: 1. A table: Assumption | Evidence quality (strong, moderate, weak) | Sensitivity (revenue change if wrong) | Suggested fix. 2. The three assumptions that could invalidate the forecast. 3. A downside scenario with the arithmetic. 4. The data to collect next. 5. Forecast wording rewritten with ranges instead of a single number. Forecasts are estimates, not financial advice. Start with your first question.
