The irony is that for all its obscurity, most startups are using at least one mission critical service that runs on elixir -- slab, pagerduty, elixir, ramp, divvy, discord. brex is probably still half ish elixir, though they claimed to be wanting to replace it with kotlin when they got some new tech leadership. I wonder how that's going. I remember working at a startup where the cto was unsure about putting trust in elixir, claiming it was an "unproven entity". I pointed out to him we used THREE of those services, do if he didn't trust elixir we should probably pivot off of those products.
