Lean B2B

Build Products Businesses Want

A practical playbook for validating B2B products fast.

by Etienne Garbugli

Lean B2B adapts lean startup and customer development specifically to the business-to-business context, where buyers and users differ and sales cycles are long. Garbugli lays out a step-by-step process for finding early customers, validating problems, and reaching product-market fit. The book is built around case studies and concrete frameworks.

Most lean startup advice is written for consumer products, leaving B2B founders to improvise. This book gives them a tailored validation process for selling to businesses with complex buying. It helps founders avoid building products no company actually wants.
