There's no killer app, as in a reason to add it to your tech stack.

The closest I've come across was trying to maintain an ejabberd cluster and add some custom extensions.

Between mnesia and the learning curve of the language itself, it was not fun.

There are also no popular syntax-alikes. There is no massive corporation pushing Erlang either directly or indirectly through success. Supposedly Erlang breeds success but it's referred to as a "secret" weapon because no one big is pushing it.

Erlang seems neat but it feels like you need to take a leap of faith and businesses are risk averse.

Isn't there this "small" company that has a chat app that is using erlang :P

Well jayd did the same thing as that small company (which I joined in 2011 when it was small and left in 2019 when it was not so small), run ejabberd to solve a problem. In our case, Erlang subsumed pretty much the rest of our service over time. When I started, chat was Erlang, but status messages, registration, and contacts were PHP with MySQL, media was PHP (with no database), but those all got sucked into Erlang with mnesia because it was better for us.

But I guess it doesn't always work that way. FB chat was built on ejabberd and then migrated away.
