If I get to repeat a patio11 by integrating them they might earn me a lot of money.
Also how innovative is Stripe really. They provide a service that is fairly obvious when you worked with Paypal or a large bank. The point is providing the service is a lot of hard work, thats what we pay them for. The mere idea of payments should not suck this hard is not their business. It is actually depositing your customers money in your bank account and frankly they don't offer that in Germany.
