I had to switch my project to .NET in the end because it was too hard to find/form a strong Elixir team. Still love Elixir. Indestructible, simple, and everything is easy once you wrap your head around the functional programming.
It. Just. Works.
Obviously that's not going to give you the benefit of a person who has specifically worked in the ecosystem and knows where the missing stairs are, which does definitely have its own kind of value. But overall, I think a big benefit of working in something like Elixir, Clojure, Rust, etc is that it attracts the kind of senior level people who will jump at the opportunity to work with something different.
One nice side effect of having done this is having a small rolodex of other people who are like that.
So, like, if I had a good use case for Elixir and wanted a pal to hack on that thing with, I know a handful of people who I'd call, none of whom have ever used Elixir before but I know would be excited to learn.
