## Instructions
- ### 1. The 30-second assessment
+ ### 1. The 30-Second Assessment
In 2-3 sentences, give your gut reaction. Is this a real problem worth solving, or a solution looking for a problem? Be direct.
- ### 2. The five fatal questions
+ ### 2. The Five Fatal Questions
Answer each honestly:
**Q1: Who is the customer, and would they pay for this today?**
- Name the specific person (job title, company stage, situation)
- - Estimate their willingness to pay, and justify it
- - If the answer is "maybe", that's a no
+ - Estimate their willingness to pay (and justify it)
+ - If the answer is "maybe" — that's a no
**Q2: Why hasn't someone built this already?**
- - List who has tried (there's always someone), with links
+ - List who has tried (there's always someone)
- Why they failed or succeeded
- - What's different now? (timing, technology, regulation, behavior shift)
+ - What's different about now? (timing, technology, regulation, behavior shift)
**Q3: What's the distribution advantage?**
- How will the first 100 users find this product?
- - Is there a built-in growth loop, or is every user acquired through paid or manual effort?
- - If the only answer is "content marketing and SEO", that's a red flag for a startup
+ - Is there a built-in growth loop, or is every user acquired through paid/manual effort?
+ - If the only answer is "content marketing and SEO" — that's a red flag for a startup
**Q4: Can this be a big business, or is it a feature?**
- Is this a standalone product, or will an incumbent add it as a feature?
- What's the natural ceiling? ($ revenue, # users)
- What would need to be true for this to reach $1M ARR?
**Q5: Can the founder actually build this?**
- - What skills and resources are required?
+ - What skills/resources are required?
- What's the hardest technical or operational challenge?
- Is this a "first hire" problem (you can't launch without a specific expert)?
- ### 3. Idea scorecard
+ ### 3. Idea Scorecard
Rate the idea on each dimension (1-5):
| Dimension | Score | Notes |
|-----------|-------|-------|
| Problem severity | | How painful is this? |
| Market size | | How many people have this problem? |
| Willingness to pay | | Will they pay enough to build a business? |
| Competition gap | | Is there real space for a new entrant? |
| Distribution | | Can you reach customers cheaply? |
| Timing | | Is this the right moment? |
| Founder fit | | Does the founder have an unfair advantage? |
| **Total** | **/35** | |
- If the input says nothing about the founder, score founder fit as "?" and ask about it in the verdict.
-
**Scoring guide:**
- 28-35: Strong idea. Validate fast and build.
- 21-27: Promising but has gaps. Fix the weakest dimension before building.
- - 14-20: Significant concerns. Needs a major pivot or a different angle.
+ - 14-20: Significant concerns. Needs a major pivot or different angle.
- Below 14: Start over. The idea has fundamental problems.

End with one of:
- - **Build it**, with the single most important thing to do this week
- - **Pivot it**, with the angle that would make this much stronger
- - **Kill it**, with why, and which adjacent problem is worth solving instead
+ - **Build it** — with the single most important thing to do this week
+ - **Pivot it** — what angle would make this 10x stronger
+ - **Kill it** — why, and what adjacent problem is actually worth solving
## Rules
- Be honest, not encouraging. False encouragement kills startups.
- Every critique must be specific and actionable.
- - If you think the idea is bad, say so clearly, then say what would make it good.
- - Name real companies that succeeded or failed in similar spaces, with a link for each.
+ - If you think the idea is bad, say so clearly — then suggest what would make it good.
+ - Use real examples of companies that succeeded or failed in similar spaces.
- Keep total output under 1500 words.
