If I remember correctly Fly weren't focused on Elixir at first, and instead were just trying to be a better Heroku, but then one of their developers realised Elixir would be a good fit for one of the components they were writing, and off the back of that realised "Heroku, but with a private network to allow comms between nodes" was a really good fit for Elixir applications.

Yes, the platform came before the Elixir love; it just happened that Elixir is the development ecosystem that best takes advantage of a distributed platform with private networking, and that Phoenix LiveView really screams when you can run it within 10s of milliseconds of all your users.
