I’ve just finished re-reading Eric Ries’s The Lean Startup. I cannot overemphasize how valuable this book is.
Just knowing the concepts it made famous (the MVP, build-measure-learn cycle, etc….) isn’t enough. You have to know how exactly the concepts work and work together.
If you are a startup founder, a would-be startup founder, or work for product development and you HAVEN’T read this yet, DROP WHATEVER YOU ARE DOING and grab a copy now.
For my second reading, I invested in buying the audio copy here.
Absolutely worth every cent.
JUAN GREAT LEAP
