This audiobook was an interesting listen. While I already knew many of the tenants discussed in it, as I work in silicon valley startups, I did notice a lot of ideas that I had not fully understood. The concept of free was something I knew existed but didn’t fully appreciate. Making you service free to get users, and then monetizing those users is a method that should not be dismissed as it is hard to compete with free. It is especially hard to compete with free done well. The book also pointed out that openness and crowdsourcing are good policies as you will get more help and better direction from the crowds than you will get by sitting in a room and thinking. You shouldn’t do everything your crowd says to do, but they will be a great source of ideas of where you could go. I hope to use these concepts in any startup I work on.
