Distributed Masonry uses Clojure to build Onyx [1], an open source distributed batch and streaming platform. We also build a realtime application platform named Pyroclast [2] directly on top of Onyx. Our code base is written entirely in Clojure. The architecture we've ended up with is hands down the cleanest I've ever worked on.
