1. The strongest reason this could be a $100M business.
2. The 3 most likely reasons it dies in year 1.
3. The single experiment I should run this week to learn the most for the least money.
4. Comparable startups (alive or dead) and what we should learn from each.

Why it works

  • Explicit 'do not be encouraging' breaks the model's default flattery.
  • Forces an actionable next step (the experiment), not just analysis.
  • Comparables ground the answer in reality, not hype.
