The traditional business model is to manage products, and the future business model is to manage users. If you only sell products, you don’t know who bought your products, and you don’t know the real feedback from users on your products. If you manage users, you can not only know who bought your products, but also know what other needs these users have, and you can even let users participate in your product design. Your users will continuously create performance for you, and it is difficult for competitors to snatch your users away.
