If a product truly adds value for you, you will engage with it more deeply. If it makes you happy, you visit it more frequently and become an active user.

engagement drives stickiness, which drives retention — and that, in turn, drives growth

Growth needs to be understood in the context of the overall market and the number of users relative to the total addressable market — and with respect to the balance between new user acquisition, churn and resurrection.

Retention is simply about users returning to your product; stickiness is about them returning of their own volition. Stickiness helps reduce your dependency on tactics such as push notifications.

the number of sessions, which is a measure of engagement, can also serve as an early predictor of stickiness. That is — engagement drives stickiness.

The more a user engages with a product, the more sticky it becomes for them, and the more likely they are to retain.

a decrease DAU is an early indicator of a decrease in WAU, which is itself an early indicator of a decrease in MAU.

The fundamental truth of this framework is that if a user finds value in your product, they will return.

Whatever your product’s core value, your greatest growth lever is creating magical moments in which users recognize that value. Without such moments, retention will suffer and growth will be difficult to sustain.

A great company focuses on sustainable growth — through engagement, stickiness and retention.
