Wouldn't recommend this book to people who have start-up experience of 3 years and more and have generally been following the tech space. 90% will seem obvious and a summary of the book will suffice if you still want to read. However, young folks in their teens or 20s and trying their hand at entrepreneurship(tech start-ups) for the first time might find something useful. <br/><br/>One positive though about the book is, unlike most business books, there wasn't one moment when I thought the authors were beating around the bush. Mostly crisp and to-the-point.
