Earlier quoted context omitted.

I'm actually the author of Luminus, and it's used as our default template for web apps right now.

(Yes, I realized and hence the question hehe. I've been bugging the list/github issues on luminus for some time now. Excellent project!)

Thanks! :)

Alex, there is also a small company called Helpshift that's using Clojure in production since 2009 :-)

Thanks! I didn't have any hope of getting them all!

I'm very curious - did you come up with all of this off the top of your head?

It's a combination of a list of articles on Clojure usage I have stashed away + conference talks + job ads + some of the companies Cognitect has worked with (there are others we're not allowed to mention). I plan to put up a list like this on clojure.org soon.

ThreatGRID, now part of Cisco, uses clojure in our malware analysis and threat intelligence platform. It's a core part of our analysis engine, which examines all the things malware does and how to detect it on the rest of your systems. We've built a 1980s "expert system" startup using core.logic.

It's also the core of our API service, and the UI built on top of that. We use clojurescript extensively in the UI, and have been moving large parts of it to Om.

It is a key technology for us, letting us build better analysis tools, faster and more performant than other languages. We have clojure code in production both in our SaaS offering, and shipped to many large finance, government, and corporate customers around the world.

We use Clojure in production to run Database Labs, https://www.databaselabs.io . The account management and billing web app is Clojure + Postgres, proxied through nginx. I couldn't be happier with Clojure for webapps.

also, do you have any references or examples of how exactly you use immutant? I looked into it but it seemed to complicated for the webapp I wanted to write, so I went with Hoplon instead. But immutant looks really powerful... I just can't imagine how I would take advantage of it.

Hey, I wrote the Pivotal Labs podcast and code you mentioned above. While we do use some Clojure(script) in Tracker, it's only used for testing in combination with Test.Check. I personally think that calling that "production" use is a bit of the stretch, but it is certainly an example of useful Clojure usage in the wild!
