The nice thing about this, from what I understand, is that unlike Gumroad, it lets you sell things for < 99 cents. Obviously, that's a huge potential market.

I would guess the $10 minimum is a way to "hide" or "bundle" these tiny transactions that you can't efficiently handle through the existing credit card/banking system.

More generally, I guess the whole Minno business model/insight is to aggregate these kinds of small transactions that can't efficiently be handled by the existing financial system. (Minno is the payment service underlying Hawt Cakes.) This is literally speculation; I imagine the founders will correct me if I'm wrong.

That's exactly the right analysis.

More generally, there seems to be an entire class of apps out there that could be really useful, but which are really hard to monetize with subscriptions and/or ads revenue alone. Think about an advanced file converter, or maybe a one-off fax service. There are also the more traditional use cases, such as purchasing a single article from an online journal, or streaming a single movie online.

Minno provides an effective alternative to monetize these services, and it does so with much more ease than with traditional payment systems.
