The entire knowledge base distilled into one page. Pin this to your wall.

The 6 Phases

PhaseGoalKey FrameworkBiggest Risk
1. IdeationFind a problem worth solvingWell test: “Who wants this so badly they’ll use it from unknown founders?”Building something nobody wants
2. ValidationProve real people will payMom Test: ask about their life, not your ideaConfirmation bias
3. PMFAchieve product-market fitSean Ellis: ≥40% “very disappointed”Premature scaling
4. Early GrowthGrow with unscalable tacticsCollison installation: “give me your laptop”Hiring before selling yourself
5. ScalingBuild the growth machineLeslie’s Compass: is it bought or sold?Losing culture during rapid hiring
6. EnduranceSurvive long enough to winDefault alive or dead?Founder burnout

The 10 Commandments

  1. Make something people want. Everything else is secondary.
  2. Talk to users. There are no facts inside the building.
  3. Do things that don’t scale. Manual first, automate later.
  4. Charge early. Paying users = validation. Free users = vanity.
  5. Focus. One metric. One channel. One thing at a time.
  6. Move fast. Speed of learning is your competitive advantage.
  7. Hire slow. Don’t compromise on quality. Ever.
  8. Watch your cash. Know if you’re default alive or dead.
  9. Pivot when the data says so. Obstinacy kills. 70% of successes pivot.
  10. Take care of yourself. Startups take longer than you think.

The Frameworks Wall

Finding Ideas

  • Well test: Deep demand from a small group > mild interest from many
  • Schlep Blindness: The tedium others avoid IS your competitive moat
  • Organic > Manufactured: Notice problems, don’t brainstorm solutions
  • Thiel’s question: “What important truth do few people agree with you on?”

Validating

  • Mom Test: Their life, not your idea. Past specifics, not future hypotheticals.
  • Build-Measure-Learn: The unit of progress is validated learning, not features shipped
  • MVP ≠ bad product: It’s the minimum experiment for maximum learning

Competing

  • Thiel: Competition is for losers. Build a monopoly (10x tech, network effects, scale, brand)
  • Altman: Competitors are a startup ghost story. 99% of failures are suicide, not murder.
  • Distribution power law: Nail ONE channel. If you try several but nail none, you’re dead.

Money

  • Default alive/dead: Expenses + growth rate + cash = will you make it?
  • Ramen profitability: First milestone. Proves model, grants independence.
  • 10-5-20 pricing rule: Start at 10x cost, raise 5% per cohort, until losing 20% on price
  • Fundraising: Parallel (not sequential), clean terms, the first check is hardest

Leading

  • Wartime CEO: Existential threat → protocol-breaking, detail-obsessed, single-bullet precision
  • Peacetime CEO: Growing market → broad creativity, consensus, culture-building
  • Founder mode: Stay engaged on what matters. Skip levels. Don’t become a manager.
  • Editing, not writing: Your job is simplifying. Barrels (ship end-to-end) > ammunition (ICs).

Team

  • Cofounders: Know them well. Equal equity. 4-year vest, 1-year cliff.
  • First 10 hires: Set the cultural DNA. Good and bad are both infectious.
  • Culture: Defined by who you hire, fire, and promote. Not perks.
  • Barrels vs ammunition: The constraint is always barrels. Find and invest in them.

Cofounder fights~20% leaveChoose well. Vest. Hard conversations early.

The One-Liner Test

If you can’t say it in one sentence, the thinking is muddled:

  • Airbnb: “Book rooms with locals, rather than hotels”
  • Stripe: “Payments infrastructure for the internet”
  • Dropbox: “Your files, anywhere”

What WeWork Got Wrong (Anti-Pattern Checklist)

If you’re doing any of these, stop:

  • Losing money on every unit and planning to “make it up in volume”
  • Calling yourself a “tech company” when you’re not (to justify valuation)
  • Inventing metrics that exclude your largest costs
  • Blitzscaling without network effects or winner-take-all dynamics
  • Raising so much money that you never face market reality
  • Letting a charismatic founder operate without governance checks
  • Confusing vision with delusion, or determination with obstinacy
