The power law governs venture returns
A tiny number of investments generate almost all the returns, while most fail. VCs must swing for rare enormous winners rather than optimize for the average bet.
Power Law
9 ideas
Chronicle from Fairchild to Sequoia to Tiger
Mallaby traces VC from Arthur Rock and Fairchild through Kleiner Perkins, Sequoia, and modern megafunds. The history shows how a distinctive financing form built the tech economy.
Venture capital as active company-building
Successful VCs shape strategy, recruiting, and governance, not just supply money. The book argues hands-on partnership, not passive capital, drives outsized outcomes.
Embracing failure as the model
The venture model accepts frequent, total losses as the price of finding a single outlier. Tolerance for failure is a feature of the system, not a flaw.
Venture returns obey power law, not bell curve
In venture portfolios, a tiny fraction of investments generate the majority of all returns, often a single deal returning more than the rest of the fund combined. This means the cost of a loss is capped at 1x while the upside of a winner is effectively unbounded, so the decisive skill is catching outliers, not avoiding failures.
Errors of omission outweigh errors of commission
Because failed bets lose at most the capital invested while missed winners forfeit returns of 100x or more, passing on a great company is far more costly than backing a bad one. VCs therefore keep 'anti-portfolios' and bias toward saying yes to ideas that look crazy, since conventional caution systematically filters out outliers.
Staged financing as tranched risk reduction
Rather than committing all capital upfront, venture investors release money in rounds tied to milestones, each resolving a specific technical or market risk before the next check. This lets investors cheaply buy options on huge outcomes, abandon losers early, and concentrate follow-on capital into winners as information arrives.
Venture capital as network-driven reputation flywheel
Success compounds because top firms' past wins attract the best founders, which yields better deal flow and more wins, making venture returns persistently concentrated among the same firms unlike public-market fund performance. Seeing VC as a network and reputation business, not a pure capital business, explains why being connected and trusted matters as much as analytical skill.
Arthur Rock and the Traitorous Eight
In 1957 eight young engineers at William Shockley's Shockley Semiconductor Laboratory in Mountain View, California, decided to quit. Arthur Rock, then a young banker at Hayden, Stone in New York, found them backing from Sherman Fairchild's Fairchild Camera and Instrument, which funded them as Fairchild Semiconductor. Mallaby treats this as the founding act of Silicon Valley venture capital.
