We use Clojure for the whole backend, Python for machine learning, and JS for frontend at Motiva AI. It's the fourth company that I worked at (UK and US) with Clojure as one of the main languages. I'd say hiring Clojure devs has been one of the best perks for working with Clojure. Consistently high quality people that I've had the honour to work with.

At Motiva, we've dabbled in other languages like Haskell, Scala, Rust, Go, etc. but Clojure has been what sticks for us on the backend team https://github.com/Motiva-AI. We are a fully distributed remote team and we are hiring. Drop me an email.
