Ask the startups that don't become a billion-dollar business

In this book, data from billion-dollar companies is compared to data from a baseline group of startups that did not become unicorns. Between 2005 and the end of 2018—the time period of my dataset—about twenty thousand startups were founded that raised at least $ 3 million each in funding.

I heard the product pitch of a few hundreds startups in 21+ years of career. I worked with dozens of them. Every founder believes he/she knows better, but the reality is that there's a sea of failed attempts behind a handful of billion-dollar successes.
