Geoffrey A. Moore is an author, consultant and venture partner. His other bestsellers include Inside the Tornado, The Gorilla Game and Living on the Fault Line.
Crossing the Chasm is derived from the author’s work as a high technology consultant in Silicon Valley. Originally, both the author and publisher assumed the book would be of interest to a mere niche group of people and would probably only sell some 5,000 copies. In fact it became a runway hit with over 300,000 copies sold.
