I'm running Alchemist Camp, where I teach Elixir and the Phoenix Framework, primarily through screencasts. It was a labor of love for the first year but now it (mostly) pays the bills. https://alchemist.camp
Man, I remember thinking that Elixir was going to take the world by storm about 5 years ago. I was so excited for it. I hope it does though, it has a lot of great things going for it, and I'd love to see it adopted.
In 2 days, I'll be launching a second product for a similar audience. https://phoenixigniter.com
Elixir is a tiny market compared to something like Ruby or even Rust, but it's my stack of choice and I love helping grow the ecosystem.
