Moving from Python/JS -> Elixir at a startup seems very high risk, have the rewards been worth it? I can imagine issues with hiring, unknown unknowns, and less libraries/support in general.
I know-- I was scared like hell. But after the first week and multiple staging releases in less than 10 days, I was on top of it. Yes, hiring is real challenge and am facing it already. However, if I, even as a startup, reach the salary threshold, then hiring is not a problem. I'd say I've yet not found a case where I couldn't find a library for my use case.
The start-up I work for uses Phoenix and Elixir. I've been there around two years now and we haven't experienced any issues with hiring or finding skilled people. If anything, I'd point to Elixir as being one of the major factors of our success.
We are a remote company, so things may not be as easy, depending on your location, if your company demands people be in the office.
