Hello there. As a (former) professional Clojure dev, I am a bit curious about companies in Brussels' (potentially wide) area that use Clojure. Do you know any? Do you maybe work for one?
There's http://www.webcomrades.com in Leuven, and I think another company in Herent that have at least some services written in clj/cljs in production. You could also join our meetup https://www.meetup.com/pl-PL/Leuven-Functional-Programming-Meetup/ we often have talks on/around Clojure :)
