My startup is using Clojure, for a webapp that is heavy in AI/statistics. Yes, compojure is early, but for us it has been totally worthwhile. A lisp that has 1) a fast implementation 2) excellent support for parallelization and 3) well supported web servers has been a huge win. We have had to reinvent a few wheels, but I would much rather re-invent e.g. user logins than Clojure + the JIT, debugger & profiler support of the JVM. Clojure is going to get better webapp support, Ruby isn't going to get better at number crunching or parallelization or get rid of its warts. So yes, we've been very happy.
