I evaluated a few things at the beginning. I was previously using Ruby/Rails and Node.js, and Rails was my go-to for full-stack webdev.

There was some interest in building a headless WordPress site, but the limitations on database design and performance led me back to a monolith. I have a general preference for monoliths when time is tight (time is always tight) -- the things you get for free are very helpful: deploy/rollback, DB migrations, API versioning, local dev workflow, CI, among others.

I'd deployed a couple small Elixir apps at my previous job, as well as some toy projects in Elixir/Phoenix. I've played with JVM languages like Scala and Clojure, I've tried to learn Haskell about five times. Elixir had a great developer experience story (a couple people can build a nontrivial app in ~weeks). It's on par with Ruby/Rails. We went all-in around September 2016, launching in early December of 2016.

Edit: I should have mentioned, I'm the CTO of The Outline.

Was there any particular reason why you didn't choose Clojure? From what I've heard, and based on my own experience, it scratches many of the same itches that Elixir does, especially in comparison to Node/Rails.

Personally I went for Elixir instead of Clojure for a bunch of reasons, but I'm very curious to hear how others feel about this.
