The Power Law

Review

I picked this up wanting to understand how venture capital actually decides things, having spent enough time near funded companies to notice the logic was not the one being described out loud.

The central idea is in the title and it reorganises everything else. Returns are not distributed evenly or even lopsidedly, they're distributed such that one investment in a portfolio can return the entire fund and most of the rest return nothing. Once you accept that, behaviour that looks reckless from the outside becomes rational. A fund that avoids losses is optimising for the wrong tail.

The history is genuinely good, from the early Californian partnerships through to the recent megafunds, and Mallaby is a real journalist rather than a cheerleader. He's willing to say when the returns came from luck, structural advantage, or being the only cheque available.

My caveat is that it's a history, not a manual. If you're a product person hoping to learn how to raise money, this explains the incentives of the people across the table, which is useful, but it won't tell you what to put in the deck. Read it to understand why investors behave the way they do, and be honest that the same power law makes most of the advice in it unrepeatable.
