Because they lack significant resources to attract customers, disruptors approach their business with a different mindset. Uber didn’t have cars. Airbnb didn’t have hotel rooms. Netflix didn’t have stores. For disruptors, revenue growth originates in one place, and one place only: customer acquisition. If such acquisition requires an asset, then the disruptor might want to build, acquire, or borrow that asset from others. But disruptors don’t regard the asset as the end game.
