Spreedly

Spreedly delivers a service to our customers that does just three things: collects payment data (mostly credit cards) on their behalf, keeps that payment data safe, and lets them make use of it however they'd like. The complicating factor in all that is PCI-DSS and more security more generally, and taking on the hard work of keeping all that data safe through each step of the process is what our customers pay us for. Further, because of all the backends we integrate with, we think "distributed system first" and are already hitting all kinds of interesting scaling challenges.
