What is Highnote's strategy for managing customer concentration risk in card issuing, given the potential revenue dependence on a few large accounts?

Yes and no. I think Marqeta probably has been a victim of some of its own success in the partnership with Cash App. That's a phenomenal program, and we love what Square is doing with the Cash App program. We feel like there are going to be certain breakout organizations that have millions and millions of customers that drive a significant portion of payments volume. 

The way we think about it at Highnote is we are very, very thoughtful from day one, trying not to get into a situation where a single customer is driving all of your roadmap and all of your commercial value. We have many different programs in many different verticals that partner with us. We’re being thoughtful about our business model  in a way where the revenue concentration risk that's happening currently with Marqeta is less likely to happen in the future for us.
