If Google is cited and used as a yardstick, this book is not about the story or the functioning of this steamroller but on this worldview services and business model in place to turn a start-up essential giant digital economy. If a bit egocentric style of the author is sometimes annoying (when I, when my son, when my company, my blog ...) I must admit that it managed to make a fairly relevant overview of the state and to highlight the main levers of what is the business model emerging in the digital industry. It grows through its analyzes to recover and restore its economic model enterprise in question. A book that disturbs and puts a big kick in the remains of the anthill ... it feels good
