Fantastic tooling, potential to live in the same language for cljs front-end/clojure backend, less code means less bugs than JS, shorter time to implement, higher productivity from smaller teams, stable core, lots of development on great libs, immutability/persistent data structures/strong concurrency patterns get you out of the tar pit, low friction to interop with JS, cljs loves npm via shadow-cljs.
Easier to list the case against. The case against is it has a steeper learning curve and it's harder to hire for.
I’d add that if you are ok with remote and the company is doing something interesting: hiring (or training) isn’t that problematic, you will actually get access to very talented & motivated people because of Clojure
If you require people to be co-located Berlin has a very strong Clojure community for example, depends on where you are though.
