The book gives you an inside glimpse of the world’s best startup accelerator – Y-Combinator. Randell Stross was allowed to monitor and analyze two batches of the program. I think every founder has dreamt of being part of this program and this book gives you an opportunity to understand what really happens in there. Each chapter is devoted to one (or more) startup where it talks about how interaction with the YC partners, fellow entrepreneurs and the startup community is helping build billion dollar companies. O and the demo day description is pretty nice. You can just imagine what it would feel to present in front of a hall full of Investors.
