Growth engines

A growth engine is a process that startups use to achieve sustainable growth i.e. growth where new customers come from the actions of past customers.

There are three growth engines, each with its own set of metrics:

1. Sticky engine of growth
2. Viral engine of growth
3. Paid engine of growth

Successful startups usually focus on a single growth engine. Chasing multiple engines at once creates confusion and leads to poor results.
