Press and industry publications describe platforms as the new panaceas for success in the digital age. Platforms promise network effects and enable companies to scale faster without owning physical assets. They help make resources more accessible to participants by facilitating sharing.

Entrepreneurs, investors and business leaders have recognized the powers of platforms and wanted to be the next Uber, Airbnb and Facebook in their respective industries.
