It's almost impossible to overstate the disruption Stripe is causing, and this is taking it to a whole other level.
We have an app (http://tulasoftware.com) that yoga studios use to run their business and we're able to compete with some very well funded companies in no small part because of our Stripe integration.
We've been guiding people through the stripe account creation process though, and having them manually enter their API keys. This basically eliminates the need for any manual intervention at all.
So awesome.
