The Internet is run primarily by four platforms: Amazon, iTunes, Google, and Facebook. The valuable lesson that Iâ€™ve learned about this is that owning a platform is critical in developing a sustainable business strategy. What is a platform? According to Phil Simon (author of The Age of Platform), a platform is defined as â€œan extremely valuable and powerful ecosystem that [â€¦] scales, morphs, and incorporates new features, users, customers, vendors, and partners.â€ A platform gives entrepreneurs a greater opportunity to scale their business for sustainable growth. For example the NewMe Accelerator (Angela Benton and Wayne Sutton), TechStars (Brad Feld and David Cohen) and The Lean Startup (Eric Ries) are great examples of platforms that were developed by entrepreneurs.
