As a Rails engineer with 14 years experience, I can say the place that should be in the 3rd panel is Shopify. They employ so many ruby and rails core committers and directly fund a good many rails gems, and ruby community infrastructure it’s insane. They’re also directly funding the development of things like the YJIT and speed enhancements to MRI itself.

Then there’s all the other places I know or worked at built on Ruby where my other long tenured ruby friends work.

• Gusto
• Airbnb
• Clearbit
• Stripe
• Github
• Gitlab
• Bold Penguin

I worked at Shopify up until a year ago. github.com/shopify/shopify repo powers almost every inch of Shopify’s infrastructure and is entirely a rails monolith. It is not the same as saying Twitter is still rails.
