That's the very assumption I want to stay away from. Hence not launching a full-blown product, but a barebone version of it. I want to see which type of customers are most drawn to it, and which ones off them use it the most.

Yes, no current users and no churn data is a bummer, but since I am just starting this, that's pretty much the hand that's dealt to me.

Thanks for taking the time in writing a detailed note. Took notes. :)
