[[The Lean Startup]] defines three engines of growth:

* ''The Sticky Engine of Growth''
** The sticky engine of growth depend highy on customer loyalty and brand. Critical for this growth engine is that the rate of new [[Acquisition rate]] must be higher than the [[Churn rate]]. 
* ''The Viral Engine of Growth''
** The viral engine of growth is power by a feedback loop that can be quantified. This is called the [[Viral loop]] and its speed is defined by the [[Viral coefficient]].
** The [[Viral coefficient]] measures how many new customers will use a product as a consequence of each customer who signs up. This must be greater than one otherwise it will not be viral
* ''The Paid Engine of Growth''
** The paid engine of growth grows linear as a function of revenue and cost per customer. This is a very common model
