Companies (like banks, enterprises) still often demand, especially for backends, specific language/runtimes and that tech often translates to Java/JVM or C#/.NET. It is getting to be less important, but we definitely encounter it a lot still and you really can suggest there that you ship something built with ‘ReasonML’ (what is a ‘reasonmul?’) (or ocaml); F#/Scala/Clojure you can get away with especially if you ship closed source (which is still also quite normal in those environments).

From what I've heard a lot of specialized finance applications run OCaml/Haskell/etc. because of the extreme need for safe and reliable code while also preserving performance.
I think 'a lot' is maybe a bit an exaggeration; also, besides maybe Jane Street, it is usually only a small portion of the IT department. But I love to hear more as I am in finance (only encountering Java/.NET basically).
Well for example, one of the most interesting applications of OCaml in finance (well, fintech) is implemented in OCaml and open source: https://gitlab.com/tezos/tezos
Then there's Bloomberg: https://ocaml.org/learn/companies.html
> Bloomberg employs OCaml in a advanced financial derivatives risk management application
Press release from Bloomberg announcing BuckleScript: https://www.bloomberg.com/company/press/open-source-at-bloom...
> We are not currently using BuckleScript on the Terminal, but stay tuned…
This seems to suggest that they were looking at programming Bloomberg terminal applications in BuckleScript, compiled to JavaScript, at least at one point.
There's also LexiFi: https://www.quora.com/Is-the-OCaml-language-used-in-quantita...
I think if you go looking, it's not hard to find OCaml in finance in certain niches.
