Aurora Operation Collection|A set of models, three steps, and the secrets of the fission and growth of educational apps

Online education is a very popular field in recent years. There are many articles on the Internet that analyze its growth model, but I found an interesting phenomenon, that is, few people talk about the growth mode of online education apps.

In fact, online education users are inseparable from APPs, especially tool APPs, such as Homework Help, Xiaoyuan Search Questions, etc., which have tens of millions or even hundreds of millions of users, and many online education companies are increasingly emphasizing user use APP sign up for courses.

Under such a trend, it is necessary to systematically sort out the operational growth of online education apps (including payment for knowledge), especially fission growth. This article will use the classic pirate model for interpretation.
