Startup Playbook
Author: Sam Altman (as YC President) URL: https://playbook.samaltman.com/
Summary
The definitive Y Combinator startup guide, covering the full startup lifecycle. Altman breaks success into four pillars — idea, team, product, execution — and provides specific, actionable advice for each. Notable for its bluntness: “mediocre teams do not build great companies,” “early founders with publicists almost always fail,” and “competitors are a startup ghost story.”
Key Claims
- Make something a small number of users love rather than something many users like
- Focus and intensity are the two words that best describe great founders
- Growth solves most problems; lack of growth is unfixable
- 99% of startup failures are suicide (internal), not murder (competition)
- The secret to raising money is having a good company — everything else is ~5%
- Culture is defined by who you hire, fire, and promote
- “A thousand people have every great idea. One actually succeeds. The difference is execution.”
