Thanks. As I mentioned in the post, I made sure that everyone sees the benefit of this product within 30-60 minutes on the platform (algorithm pushes new users on top of list to get them few followers quickly)

I waited for users to start asking for some extra features or more seeds/credit points (people get 15 seeds to start with). I also clearly mentioned that we have two things in pipeline 1.) Another useful free feature 2.) Pro Accounts as low as $15(will be available for only first 100)

So, by first week, people had tested the fruits of being on pinwoot, so they started queuing up for pro accounts.

In 2nd week, I allowed people to start buying seeds for as low as $5 and maximum $29. So, my users are buying those seeds on regular basis for last 2.5 weeks. I haven't launched pro accounts yet - once those are launched, I may see monthly rev at around $15K.

In nutshell, make that one feature super awesome but add a limit to it such that people get addicted to it and in want for more, they pay you.
