About the Author

Étienne Garbugli works at the intersection of Tech, Product, and Marketing. He is:

Why This Book Was Written

While customer development was born out of B2B enterprise selling from Steve Blank's "The Four Steps to the Epiphany," the body of knowledge available outside of that book was small to non-existent. Garbugli wrote Lean B2B to help entrepreneurs save time in the customer development process and successfully navigate the unique challenges of B2B markets.

The B2B Challenge

B2B markets present unique challenges compared to B2C:

• Longer sales cycles with multiple decision-makers
• Complex organizational buying processes
• Higher switching costs and risk aversion
• Smaller, more concentrated customer bases
• Technical integration requirements
• Compliance and security considerations

Lean B2B provides specific techniques for navigating these challenges.
