Since there's no demo's I had a look at a couple case studies..

It looks / feels like stripe but without the brand recognition, I'd hope it's more cost effective than competitors but having to contact them for pricing doesn't inspire confidence. I also don't see how this is any more frictionless than competitors. On the flip side I'm a little blown away by how big the team is and how many jobs they have listed considering it's only launched a couple hours ago - whoever bank rolled this has a lot of faith. Congrats on the launch either way.
