Platforms are widely observed in modern economies.Thanks largely to technology, new platforms are being created at an increasing rate: e.g. Airbnb, DropBox, KickStarter, and Uber. Traditional businesses are being reconceived as platforms e.g. U.S. Postal Service, newspapers (Huffington Post). In creating strategies for platform markets, managers have typically relied on assumptions and paradigms that apply to businesses without network effects. As a result, they can make errors in pricing, supply chains, product design, and strategy that can be avoided if they understand the rules of the new platform economy. Our goal in creating this site is to help managers operate effectively in platform business environments by providing a set of theory, frameworks, and tools to analyze and manage existing businesses and to develop launch strategies for new ventures.
