Not sure what exactly it means to be "sponsored", but quite a few companies and individuals give financial support to clojure:

Was hoping this would take care of cash flow issues and let Rich focus on Clojure without distraction. It doesn't appear that it does; although, it's nice to see commercial Clojure support on any level.
As the original press release mentioned, Contegix is currently providing two servers: build.clojure.org and dev.clojure.org. That's what we needed, so that's what we asked for. :-)
As others have mentioned, Contegix is one of many organizations and individuals supporting Clojure. Nowhere is the excitement around Clojure more visible than in the wide variety and diversity of support coming from the Clojure community.
if so, pretty easy and cheap to do in a world with Linux VM's and cloud provider API's. They may have figured it was a net-win due to the publicity/eyeballs gain.
