Two years ago, CircleCI posted about how they deploy their 100,000 lines of Clojure backend code and 30,000 lines of ClojureScript code to Google App Engine. Also, Walmart has been using Clojure "at scale" since before 2015. And based on a related tweet, the project at that time had 66 modules, 3000+ files, 560,000+ LOC (of Clojure). Last measure, Walmart was the largest US retailer at $374 billion annual revenue. I'd say their dependence on Clojure is a pretty good validation of the language's capability.
