Eric Ries had very kind things to say about The Entrepreneur’s Guide to Customer Development in a recent blog post:
I wish I’d had a book like this one, to help me figure out how to get started with customer development step-by-step.
…
Brant and Patrick undertook a difficult challenge: to provide a generally accessible introduction to Customer Development, without diluting its impact or dumbing-down its principles. I think they’ve succeeded.
David Crow of Startup North has also blogged about it:
I bought a copy yesterday based on Eric’s recommendation. It is a phenomenal resource for learning Customer Development. Patrick and Brant have done a great job writing an understandable how-to guide for using Customer Development and Agile Development in a Lean Startup.
Lastly, some comments over at Hacker News about the book:
“This is actually the fastest (other than maybe at a grocery store) I have ever made a purchasing decision. It was under 60 seconds.”
“Beautifully done.”
“Very happy to see a 4 steps like book aimed specifically towards startup founders”
“Wow, this looks gorgeous in fullscreen mode. Can’t wait to start reading :)”
“I literally said “wow” as I went through the sample. This is a beautifully made PDF and I’ll be sure to buy it soon. Amazing.“
