Platforms are changing entire industries and creating entirely new markets. While platforms may look straightforward as technology, the ecosystems of adoption they enable and the interactions that ensue cannot be designed or managed by the rules of traditional business. Sangeet Paul Choudary, author of the international bestsellers Platform Revolution and Platform Scale, lays out a structured approach to designing platform firms, firms where value creation and governance models are structured to account for participating ecosystems. Illustrating factors from platforms that have now gained huge traction, this keynote lays out imperatives for the industrial firm in the age of platforms.
