"Eric has created a science where previously there was only art. A must read for every serious entrepreneur - and every manager interested in innovation." - Marc Andreessen, co-founder of Andreessen Horowitz, Opsware Inc. and Netscape "This book should be mandatory reading for entrepreneurs, and the same goes for managers who want better entrepreneurial instincts. Ries's book is loaded with fascinating stories - not to mention countless practical principles you'll dearly wish you'd known five years ago." - Dan Heath, co-author of "Switch "and "Made to Stick "Ries shows us how to cut through the fog of uncertainty that surrounds startups. His approach is rigorous; his prescriptions are practical and proven in the field. "The Lean Startup" will change the way we think about entrepreneurship. As startup success rates improve, it could do more to boost global economic growth than any management book written in years." - Tom Eisenmann, Professor of Entrepreneurship, Harvard Business School
