I co-organize ChicagoRuby, and one recurring part of that work is finding local companies that use Rails/Ruby and might be open to hosting community meetups.

While doing that, I started keeping track of Rails/Ruby-powered companies with a Chicago presence. The list ended up being much larger than I expected, which was honestly encouraging to see.

Instead of keeping it in my private notes, I thought I’d share it here in case it’s useful for other Rails/Ruby developers — for job search, networking, meetup hosting, or just getting a better sense of the local Rails/Ruby ecosystem.

I kept the format intentionally simple: company name + public website I found.

I’m using “Rails/Ruby-powered” broadly here: companies where I found signs of Rails/Ruby usage, past or present — not necessarily companies whose entire product is built on Rails or Ruby, and not necessarily their current primary stack.

This is definitely not a complete list. If you know other Chicago-based or Chicago-present companies using Rails/Ruby — or if any company has moved away from Rails/Ruby — corrections and additions are welcome in the comments.
