Customer Development = The pursuit of customer understanding

Part of Customer Development is understanding which customers make sense for your business.  The goal of listening to customers is not please every one of them.  It’s to figure out which customer segment served his needs – both short and long term. And giving your product away, as he was discovering, is often a going out of business strategy.

The work he had done acquiring and activating customers were just one part of the entire buisness model.
