The 10 hooks

  1. 1."197 of the 200 dead startups I studied died the same way. It wasn't the product." [curiosity gap] — the near-total number begs the question, and founders need to know if it's them.
  2. 2."Running out of money is not why startups fail. I checked." [contrarian claim] — attacks the most repeated line in startup culture; disagreement drives replies.
  3. 3."I spent 6 weekends reading 200 startup post-mortems so you don't have to." [authority borrow + specific number] — earns the right to the conclusions with visible effort.
  4. 4."The founder had 14 months of runway, a working product, and 40 paying customers. He shut down anyway." [story cold-open] — concrete details make it feel like a documentary, not a listicle.
  5. 5."If you're pre-launch and 'polishing', this is about you." [direct callout] — names the exact reader behavior; uncomfortable = memorable.

Top pick

#4 — story cold-opens outperform stats on X because they defer the lesson; the reader must click to resolve the contradiction (everything was fine, yet he quit).

The follow-through line

"His post-mortem was one sentence long — and it's the same sentence in 61 of the 200: 'We built something nobody wanted badly enough to pay twice.'"
