Notes 01–02 cover Sam Altman's complete idea × product × team × execution × luck framework. Note 03 (Paul Graham) is the mindset layer — when to start and how ideas arrive. Note 04 (Adora Cheung) is the tactical playbook — zero to many users. Note 05 (Peter Thiel) is the strategy layer — why to aim for monopoly and how it lasts. Note 06 (Alex Schultz) is the growth engine — retention first, then operate for growth. Note 07 (Kevin Hale) is the love layer — make users love the product and never stonewall them. Note 08 (Tang · Williams · Kan) is the hustle layer — do things that don't scale, and treat press as a tool. Note 09 (Andreessen · Conway · Conrad) is the capital layer — be so good they can't ignore you, and peel risk round by round. Note 10 (Lin · Chesky) is the culture layer — design your values and hire for them, because culture becomes brand. Note 11 (Collisons · Silbermann) is the team-building layer — the first ten hires are really your first hundred. Note 12 (Aaron Levie) is the enterprise layer — the market is 22× bigger; win it with a wedge and consumer DNA. Note 13 (Reid Hoffman) is the founder-mindset layer — hold the paradoxes, and persist or pivot on your thesis's confidence. Note 14 (Keith Rabois) is the operating layer — edit the company, and multiply your barrels. Note 15 (Ben Horowitz) is the management layer — every decision is read by the whole company, so weigh all three perspectives. Note 16 (Emmett Shear) is the user-research layer — interview behavior not features, across all three user groups. Note 17 (Hosain Rahman) is the hardware/product layer — build the whole system around a WHY people can't live without. Note 18 (Nathoo · Levy) is the mechanics layer — keep the legal/finance/HR plumbing simple and standard so it never bites you. Note 19 (Bosmeny · Seibel) is the go-to-market layer — you are the salesperson; shut up and listen, and pitch in 30 seconds then 2 minutes. Note 20 (Sam Altman) is the scaling layer — shift from building a product to building a company, and survive the long trough of sorrow.

The big ideas at a glance

Pillar	The one thing to remember
Idea	Mission-driven, hard to copy, big market in 10 years. The best ideas look bad at first.
Product	A small number of users who love it beats a large number who like it.
Team	Hire slowly, never mediocre, be generous with employee equity. Cofounders: tough + calm, vesting from day one.
Execution	Pick the 2–3 things that matter, say no to the rest, and never lose momentum.

How this folder works

• One note per source. Numbered (01-, 02-, …) so reading order is preserved.
• Faithful to the source. Quotes are real; where a source doesn't cover something, the note says so instead of inventing it.
• Relative Markdown links connect related notes (e.g. [Teams & Execution](02-teams-and-execution.md)).
• assets/ holds the SVG diagrams, embedded into the notes and rendered inline by GitHub.
• Every note ends with action items — questions to ask about my startup.

Diagrams

Four pillars — the framework	Love > Like — concentrate the love
Momentum — a tiny edge compounds	Leading edge — live in the future
Retention — flatten into a core	Honesty curve — paid feedback is honest
Value = X×Y — capture beats size	Concentric — start small, expand
Operate for growth — star · moment · margin	Virality — payload × conversion × frequency
Dating → marriage — love at human scale	Knowledge gap — lower it, don't add features
First-users boulder — hardest at the start	Press funnel — story types + the process
Onion of risk — peel a layer each round	Outlier math — 15 companies, 97% of returns
Five dysfunctions — build up from trust	Culture = brand — two sides of one coin
First 10 = 100 — the DNA multiplier	Value-investor hiring — find undervalued talent
Market delta — $170B vs $3.7T	The wedge — start small, then expand
Founder paradoxes — hold both poles	Investment thesis — persist or pivot
Editor's job — simplify · question · allocate · voice	Barrels vs ammunition — velocity = barrels
Whole-company eyes — decide for everyone not in the room	Three perspectives — your side · theirs · the culture
Three user groups — non-users grow the market	Interview do's & don'ts — behavior, not features
Creation process — explore → validate → concept → develop	Context engine — on-body data makes everything smarter
Vesting curve — 4 years, 1-year cliff	Mechanics lifecycle — do this, avoid that
Sales funnel — prospect → shut up → close	Pitch structure — 30 seconds, then 2 minutes
Product → company — the founder's shift	Trough of sorrow — survive ~1,000 days
