In many ways a more profound tome than Lean Startup, this one examines the role that ego and leadership play in the process of iterating and adapting to a more successful business model.
Notable is the difference between a business model and a value chain or product. Your goal as an entrepreneur is to create a business model that's bankable, and not a product that's sellable.
I'm also very impressed by the book's IRL examples of companies doing things correctly and also doing them very, very not-correctly. I would do well to review and dig into this book much deeper.
Perhaps that's a bit too jaded for most people, but it's certainly a view of business that I've been meaning to adopt and internalise for a long time.
This book is definitely the least forgiving entrepreneurship book I've read in a long time, and as such deserves the title of BANGER OF THE WEEK.
