Given your love for Lisp, and your knowledge of Erlang, perhaps Robert Virding's Lisp Flavored Erlang (LFE) might be of interest?
http://lfe.io -- among other things, the site has tutorials and some edits of Lisp books (e.g. SICP) rewritten to use LFE.
(And, from what I've heard, LFE is being used in financial apps, though perhaps more along the lines of expert-systems than regular financial apps? (Sadly, my knowledge is at best second-hand)).
P.S. Nice to finally run into someone who has actually used Wings3D -- it gets brought up as an example of a significant Erlang project, and I know there's a community of people who were/are using it, but, since it's not a technically-oriented tool, even at Erlang conferences one is unlikely to run into Wings3D people.
I delved into LFE, and I was a proponent when Elixir was just catching on, but Elixir's momentum just washed it away. I believe Elixir earned it, but I think it had a heavy kickstart from all of the Ruby programmers who took to it. And they say syntax doesn't matter ;)
It is my understanding LFE makes a lot of compromises as a list in trying to work nicely with the Erlang VM (BEAM). I really wish Gleam kept the more Haskelly/ML syntax instead of shooting for the popularity contest by becoming more Algol or C-like. Slim Whitman allegedly sold more records than the Beatles, but I would rather listen to the Beatles!
