I cannot comment in any way on financial matters, but like Cees, I am a principal engineer at PagerDuty, and I can tell you that in terms of total LOC, our Elixir use may seem modest because we have a lot of code that was written X number of years ago in Ruby or Scala. However, if we look at new services being developed, we use a lot of Elixir, it is our default choice. This dichotomy is very usual in our industry. What we have reflects our entire history, and the history of tools available when we wrote all that code. But what we write today reflects our priorities today, and the tooling available today. Now ask me about front-end development. Yes, we have some CoffeeScript/Backbone still in production, but we aren’t doing any new work in it!
