Quite a few members of the Clojure core team and community work there, as evidenced by the intersection of http://thinkrelevance.com/team and http://clojure.com/about.html.

In addition, Relevance has had a close relationship with Rich for years, as such we've had a major hand in the development of Clojure, ClojureScript, Datomic, core.async, Pedestal, Simulant, and many other Clojure projects.
