Stage 7: Monetization

The Milestone: 10% of top of funnel visitors become paid users.

Conversion to paid can happen at very different points in time and one app may require a very different conversion rate than another in order to have a good business. For products with a trial, you want a very high conversion rate from trial to paid, since you have explicitly created a pay wall, and a user has gone through the work to sign up for the trial, so probably has strong intent. Netflix has an epic 93% conversion rate from trial to paid.
