I was sceptical a few months ago. But the growth rates even before this week are very impressive and a sign they can execute well. It's more than a church app - schools alone could be huge additional. And this is not a crowded trade. Big brokers don't cover it and there's not much chatter about it. One consequence is that volume is usually low (not this week) so can be hard to get in / out without moving it a way. That will change once the instos start to bite. I have no research to back this up but I think it could have a lot further to run. I bet I can't hold onto mine all the way up though!
