A closer look
The Y Combinator chapters show the pressure of demo day and fundraising. He describes pitching investors and the games played around term sheets.
The split acquisition is the book's most famous story. With both Twitter and Facebook interested, he used one offer against the other and ended up dividing the team, which strained his cofounders' trust.
Inside Facebook he worked on ad targeting at a time when the company was racing to make money from its users. He explains in simple terms how ad auctions and data work.
He doesn't spare himself or others, and some readers find the tone hard. As a look at how deals and products actually get made, it offers lessons most success stories skip.
