IIRC there are still many large companies using Ruby/Rails still, they've just also diversified their tech stacks (as larger companies tend to do). AFAIK the list includes: GitHub (MS has a few Rails-based acquisitions now), Airbnb, Groupon, Square, Cookpad, Kickstarter, Hulu, etc..

Pretty sure Stripe is a Ruby shop as well.

One of the biggest. They recently released Sorbet, a gradual type checker for Ruby.

I sometimes forget how vast and diverse the whole industry is, so many tech. stacks and ecosystems.

JP Morgan Chase and McKesson both use Ruby with McKesson leading the pack in RoR LOC among the Fortune 50

IIRC it's ruby, but not rails

[yellow_lead]

Gitlab too it seems.

Insiders at Airbnb told me they are (almost) completely off Rails now. They moved their website to the jvm.

If all you want is the JVM JRuby and its Truffle variant are viable options.

Seems at some scale this usually happens.

I believe AirBnB and Groupon are off Rails ( And Ruby ).

So the big one for Rails are Shopify, Github, Cookpad, Gitlab. For Ruby ( Not Rails ) That would be Stripe.
