Prompt
Act as a skeptical but constructive startup mentor.
My idea: {{idea}}
Target customer: {{customer}}
Available resources: {{resources}}
1. Restate the idea in one sentence: for whom, which problem and how it solves it.
2. List the 5 critical hypotheses that must be true for it to work (problem, customer, willingness to pay, channel, costs).
3. For each hypothesis, propose an experiment lasting under 2 weeks and costing under {{budget}} to validate it, with the success metric.
4. Main risks and red flags that mean I should drop or pivot.
5. 10 questions to interview potential customers without biasing answers (do not ask “would you buy…?”).
Be direct: if you see a serious problem, say so clearly.How to use it
The real value is in running the interviews and experiments, not just reading the analysis. Come back with the results and ask the AI to interpret them.
Usage example
Idea: monthly houseplant subscription with care guides for offices.
Sample output
The idea in one sentence
For families whose elderly parents live alone and get stuck with phones or TVs, an app that sends a trusted student to fix it in person.
Critical hypotheses and experiments
| # | Hypothesis | Experiment (< 2 weeks, < $200) | Success metric |
|---|---|---|---|
| 1 | The problem is frequent and painful | 15 interviews with adult children aged 40–60 | ≥ 10 describe a recent episode unprompted |
| 2 | The adult children pay, not the seniors | Landing page with per-visit price + $100 in local ads | ≥ 5% of visitors leave an email with price shown |
| 3 | Families trust a stranger in the home | Pilot with 5 families you know and vetted students | 4 of 5 would book again |
| 4 | Students are available | Flyers at 2 campuses + sign-up form | ≥ 20 sign-ups |
Red flags
- Trust and safety: if families won't accept anyone without a background check, your operating cost jumps.
- If people only want it "free, just once", there is no recurring business…

Frequently asked questions
Can the AI tell me whether my idea will succeed?
No. It helps you spot the riskiest assumptions and design cheap tests; only real customer behavior (interviews, pre-orders, sign-ups) can validate the idea.
What makes a good validation experiment?
One that measures a real action, such as a pre-order, a deposit or a booked call, rather than opinions. Set the success threshold before you start so you cannot move the goalposts.
