Lousy title, abysmal design, too much text, and in desperate need of an editor. Also, targeting a very small audience (startups and PDM-nerds), with very little to give to other audiences…

But a damn good book, that tells it like it is, and don't mince words! I loved it! It introduces the Customer Development Model, which in my opinion have been missing from the brain cells of too many entrepreneurs!

This book is highly recommended for would-be entrepreneurs or VCs or anyone that have to deal with people that are convinced they have invented the next roasted toast. If you are not in these segments, you can probably read it anyway and get something out of it, that you can use, even if it is very much targeted book.
