Finding and increasing growth is critical to an early stage business.

But it’s also hard to explain, and on the surface it can look very tactical: you isolate something that works, then test to see how much you are able to increase it. 

If you’re good you’ll work on a bunch of these tests at once, and funnel them into one metric that drives all of your efforts, and revenue. That one metric is often something like average daily use (DAU) or how likely they are to refer a friend (using net promoter score or similar). The key is to focus on a metric that drives your core business, and rises all of the other metrics, including revenue.
