The core of Four Steps to the Epiphany is the base for the Lean Start Up method.

Blank points to several traps that companies fall into causing them to fail. The customer-centric theory is a key point in successfully selling an idea before spending on marketing or scaling. This book is filled with examples, charts and illustrations to show how to turn a startup in to a company.

The book teaches strict control of finances as well as process efficiency, cash-flow-management, human resources and long-term bootstrapping.
