"Catalyst Code is an excellent account of the importance of the platform business model. Combining proven business ideas with economic analysis, it provides an unusually clear picture of the strategies that have enabled companies like Microsoft to create entirely new industries by bringing two or more groups of customers together and providing value to both sides. This is an important book for anyone interested in understanding how breakthrough businesses can be built in today's economy."

--William H. Gates, Chairman, Microsoft Corp.

 "Catalyst Code is key reading--a must! It tackles a fundamental set of issues for business: how to bring one's business model successfully forward, and how to ensure sustained progress. The catalyst mind-set is key to this."

 -- Peter Lorange, President and Nestlé Professor, IMD, Lausanne, Switzerland

"Evans and Schmalensee reveal the inner workings of what is rapidly becoming a new model for businesses. It offers the clearest description yet of the business strategies behind some of the world's most influential companies. Catalyst Code is a fascinating read for anyone interested in understanding companies that could shape our future."

--Peter S. Lynch, Vice Chairman, Fidelity Investments

"Catalyst Code shows that in the Internet Age, the greatest business successes will be based on creating communities in which buyers and sellers are brought together efficiently, rather than on making a new product or providing a new service. This well-written book provides a clear road map to becoming a winner in this multi-trillion-dollar market opportunity."

 --Patrick McGovern, Founder and Chairman, International Data Group

"This is a penetrating and thorough analysis of businesses that bring two different sets of customers together and get them to interact. These businesses--now known as catalysts--are increasingly important and are disrupting many traditional industries. Entrepreneurs, executives, and analysts will greatly benefit from the framework and examples that Evans and Schmalensee present."

-- John S. Reed, former Chairman, Citigroup
