What they did

In their words
Sub Club by RevenueCat · Pivots, Funding, and Building Apps That Last – Greg Cohn, Burner“But using that as a way to say, "Well, you may be done with this transaction, but maybe you want a new number." And so, we do retain a certain number of people into a second shot there.”
