Value Systems

1. What Makes a Company Great

After the dot-com bubble, valuations driven by mood and social proof proved worthless, so this class asks how to think about business value objectively. The anchoring questions are personal — what can I do, what do I find valuable, what do I see others not doing — and they converge on one big question: what valuable company is nobody building?

1. 1

   Create value

   The non-negotiable starting point: a company that creates nothing of value cannot be great, no matter how it is packaged.

2. 2

   Be durable

   The company must last. 1980s disk drive makers created real value but were replaced so fast they captured little of it.

3. 3

   Capture value

   You must keep a meaningful slice of the value you create. Isaac Newton created enormous value for the world and captured almost none of it.

Airlines are the canonical failure case: they create huge value for society and employ enormous numbers of people, yet historically the airlines themselves have never really made money. Value creation without capture makes you socially useful but not a great business.

2. Valuation: Tech Value Lives in the Future

In practice, startup valuations are often set by social heuristics — incubator conventions like a $10M cap — rather than analysis. Guy Kawasaki's tongue-in-cheek formula captures the spirit: pre-money valuation equals $1M per engineer minus $500k per MBA. Serious valuation instead rests on a few standard tools.

• P/E ratio: market value per share over earnings per share — widely used, but it ignores growth entirely.
• PEG ratio: P/E divided by annual earnings growth — it corrects for growth and should generally be below one.
• Time value of money: a dollar today beats a dollar tomorrow, so future cash flows get discounted back via NPV.
• The key inequality: the growth rate g must exceed the discount rate r, or the company simply is not growing enough.

Old Economy businesses concentrate their value in the near term: investors watch whether cash flows hold up over the next 5–6 years. High-growth tech companies are the mirror image — they lose money at first, and when g exceeds r, a typical model puts about two-thirds of total value in years 10 through 15.

Two live examples. PayPal at 27 months old was growing 100% a year; the original models put its value arrival around 2011, but with growth still at 15%, most of PayPal's value looked like it would not come until 2020. LinkedIn in 2012 had a roughly $10B market cap at a P/E near 850 — defensible only because DCF assigned about $2B of value to 2012–2019 and the remaining $8B to 2020 and beyond. Both valuations are bets on durability: the company must still matter decades from now.

3. Durability: Be the Last Mover

If most value arrives in years 10–15, then moving first is worthless if you fade before then. The disk drive makers moved first and died; whoever occupies the market at the end captures the value. The goal is not to be the first mover but the last mover — the company that makes the final, durable move in its market.

You must study the endgame before everything else.

That is chess grandmaster José Raúl Capablanca's advice, and it maps directly onto business: plan from the endgame backwards. Ask what the market looks like when the dust settles and whether your company is the one still on the board.

4. Perfect Competition vs. Monopoly

Textbooks treat monopoly as the rare exception and competition as the norm. Thiel flips the question: maybe perfect competition is the default only in textbooks, while in reality great tech companies routinely build monopoly-like advantages through economies of scale, patents, and uniquely low production costs.

• Lerner Index: (price − marginal cost) / price, from 0 (perfect competition) to 1 (monopoly); hard for regulators to compute, but worth tracking internally.
• Herfindahl-Hirschman Index (HHI): sum of squared market shares of the top 50 firms; above 0.25 means highly concentrated, possibly monopolistic.
• m-firm concentration ratio: combined share of the 4 or 8 largest firms; above 70% signals a concentrated market.
• Legally, monopoly power alone is not unlawful under the Sherman Act — it must be paired with anticompetitive conduct.

Monopoly has real downsides — lower output, higher prices, price discrimination, and possibly less pressure to innovate. But the innovation argument cuts both ways: if you build something dramatically better, charging well above marginal cost is exactly how creators get rewarded, and durable profits are what make long-term planning and deep project financing possible at all.

5. The Ideology of Competition

PayPal could not out-muscle credit card giants in a scale business, so it had to differentiate decisively. It built sophisticated fraud detection software — cheekily named 'Igor' after a notorious hacker whose peers ran dark markets like Carders World — and it engineered instant-feeling payments by pulling users' bank account details, modeling balances, and working around ACH delays. The lesson: even a handful of competing services quickly creates a brutally competitive dynamic, so a decisive advantage is essential.

The more intense the competition, the less likely you'll be able to capture any value at all.

Even the phrase 'perfect competition' is loaded — nobody calls it 'ruthless' or 'insane' competition. The bias exists because competition is easy to model, statically efficient, and politically easy to sell. But in a dynamic world with no equilibrium, the model is irrelevant, and psychologically it is corrosive: all the benefits go to society, none to you. The Big Law treadmill makes it vivid — Stanford Law graduates grinding toward partnership with terrible odds, most quitting before they can even fail.

Globalization gets framed as a flat-world sprint — a race to the bottom where you take a pay cut because someone elsewhere is cheaper. Technology offers the opposite metaphor: the world as Mount Everest, jagged and unique, where vast differences are possible. Which brings us to the most common startup mistake — assuming a bigger market is better. Thiel calls that utterly, totally wrong: restaurants sit in a huge market with terrible profits, while a well-defined, smaller market is one you can actually own.

What valuable company is nobody building?

6. Networks, VC, and the Endgame

Venture capital itself is not really a business of managing big pools of money — it runs on discreet networks of affiliated people with unique access to entrepreneurs. The network is the value proposition: personal, idiosyncratic, impossible to commoditize.

The PayPal network — friendships compounded over a decade into something franchise-like — is not an anomaly; it is arguably what every great tech company looks like. Pulling the threads together: the winning shape is a last-mover monopoly built on non-commoditized relationships, one that creates value, endures to the endgame, and actually captures what it creates.
