The document discusses how software platforms can help companies identify, capture, and retain customers. A software platform provides common elements and an application programming interface that external developers can use to build applications. This allows developers to focus on unique features while leveraging the platform's core functions. The platform approach also makes applications sticky since replacing the platform would require rewriting code. The document provides the example of a video compression software platform that delivers new standards and capabilities via software downloads, helping companies in a changing video world.
