This Strategy e-book provides an overview of why startups are not smaller versions of large companies. It explains how startups search for a business model using Customer Development, and explains the overall customer development methodology, and key implementation steps. It is designed for founders, advisors, entrepreneurs and others curious about how the Customer Development process works. Many readers prefer to use the Strategy Guide along with either The Startup Owner’s Manual for Physical Channel Startups or The Startup Owner’s Manual for Web/Mobile Startups as they work to build a successful startup.
