Target market: {{target_market}}
My background: {{founder_background}}

Give me:

1. **First Reaction Score**: 1-10, gut feeling. Don't soften it.

2. **Market Reality Check**:
   - Does this problem actually exist? (Evidence)
   - How painful is it? (Painkiller vs vitamin)
   - How are people solving it today? (Direct and indirect competitors)
   - Market size estimate (TAM, SAM, SOM)

3. **Competitive Landscape**:
   - Who has tried this before? What happened?
   - Current players and their strengths/weaknesses
   - What's your unfair advantage? (Be honest if you don't have one)

4. **Business Model Stress Test**:
   - How would you make money? (pricing model)
   - What are realistic unit economics?
   - Customer acquisition cost estimate
   - Time to breakeven rough estimate

5. **The Hard Questions**:
   - Why hasn't a big company done this?
   - What changes if Google/Apple/Meta enters this space?
   - What's the biggest technical risk?
   - What's the biggest market risk?

6. **If You Proceed**:
   - Smallest possible MVP to test the core assumption
   - First 10 customers: who are they and how do you reach them?
   - Key metric to track in the first 90 days
   - What would make you kill the idea?

No cheerleading. I need clear-eyed assessment, not encouragement.
