I like that they're very developer focused. I mean, heck -- they have the code right on their home page showing you how to run a credit card transaction, and it's not very long. I wish all of our products were that easy. But...there's a couple of growing pains to being a big payments company: (a) regulators look at you with more scrutiny, and (b) you really have to do everything you can to prevent fraud losses. We're handling that pretty well today. I'm not sure Stripe is there just yet.
