Thousands of Entrepreneurs & Innovators Use Lean B2B
“Lean B2B has earned its place in the canon for any enterprise founder. I somehow stumbled on the first edition of the book years ago, and it helped fundamentally, positively change the way I approached building my companies. I attribute many of the mental models & frameworks I use to win as an enterprise founder to Étienne’s writing.”
CEO & Founder, Knoetic
“Creating a business that sells to other businesses is extremely difficult. You will face many obstacles–poor access to decision-makers, difficulty acquiring users to test assumptions, investors prematurely pushing growth, and so on. The gymnastics needed to check waste in the face of these obstacles is intimidating. Lean B2B is an indispensable tool that will help you apply lean entrepreneurial skills to complex business ecosystems.”
Author of Disruption Proof and The Lean Entrepreneur
“When my co-founders and I started Loopio, we used Étienne’s Lean B2B principles to guide our actions, especially with customer conversations and research. This ensured that every line of code we wrote was translated into raw value for our customers. If you want to steer the ship in the right direction from day 1, this book will show you the way.”
