1/12 Why All-in-One Apps Fail at the Level of Product Design
I used to be a product manager, and then a founder. I have shipped dozens of products. Most of them failed; a few became hits in their day. In this piece I want to argue, from product principles, that an all-in-one app cannot work at the level of product design logic. It is the same as a design that breaks a technical principle: if the principle does not hold, no amount of resources will build it.
I will start with two apps, TikTok and WeChat, and a book, Positioning.
