Thanks to the very first sponsor, Brick Alloy. Brick Alloy is a band of senior consultants that solve really hard scalability and security problems. These are the people behind the Lift web framework for Scala, which is the most secure web framework out there. They help you with the whole stack, from the user experience down to the scaling infrastructure.
They also support lots of Clojure-related things you've heard of: ClojureBridge, Typed Clojure, and Clojure/West, among others. They have a very interesting organization: it's more like a law firm where everyone brings in clients and they share in successes. Check out their team and say hi on Twitter.
