Ben Thompson from Stratechery on what makes companies like Amazon and Uber so successful: strong customer relationships as an intermediary to products and services.
I wrote last month about Aggregation Theory, and both Amazon and Uber are examples of the theory in action: Amazon doesnt make the stuff they sell (mostly), but they sell everything to a huge number of customers in the market with whom they have an ongoing relationship. Uber is even more distinct: the company doesnt own the cars that provide its service but instead owns the customer relationship. Both are enabled by the Internets radical lowering of transaction costs and the possibilities for scale that result.
The point of leverage for these Internet companies is those consumer relationships: Amazon attracts a wide range of suppliers and merchants eager to sell to their customer base, and the company is not shy about leveraging said customer base to extract value from its suppliers. Similarly, Uber continually squeezes drivers with lower prices and higher fees, even as it remains the top choice for drivers because of its rider liquidity.
