Personally I spent most of my learning curve on the BEAM facilities rather than Elixir itself. Elixir as a language is simple and fairly imperative, it's quick to pick up.
Using the language for data transformations and such is a breeze but learning the concurrency primitives, message passing, OTP tooling and behaviors is where the real work is in my opinion, when building distributed systems on top of BEAM.

In my experience the opposite is true.
I've been able to introduce the BEAM in a large company (where I work) but the barrier has been they don't know it, they know very well the JVM and they don't care about the language if it can produce a runnable jar.
I would really use the JVM more if I could program it in Elixir.
I don't think introducing the BEAM is the hard part, I think it's all about the language barrier.
