Uber, the world's largest taxi company, owns no vehicles. Facebook, the world's most popular media owner, creates no content. Alibaba, the most valuable retailer, has no inventory. And Airbnb, the world's largest accommodation provider, owns no real estate. Something interesting is happening.

Uber no té vehicles en propietat, Facebook no produeix continguts, Alibaba no té inventaris, Airbnb no té hotels... tots proporcionen un interface a productes... Curiós.
