There are a few typical examples that are given whenever this question comes up: - ITA Software does airline scheduling in Lisp. - Naughty Dog Software created a Lisp-derived scripting language for several of its games, including Crash Bandicoot. After they were acquired by Sony, their underlying technology was rewritten in more mainstream languages. - Paul Graham built ViaWeb in Lisp. (also rewritten after acquisition) - AutoCAD uses Lisp as its scripting language, and several other CAD providers have followed suit. But you are right: it isn't particularly popular. To use it commercially, you either need to be working alone, or you need to stumble into one of the few pockets of industry where it is used -- usually established by someone working alone. :) Here's an old-ish discussion on the subject: http://news.ycombinator.com/item?id=75126 http://news.ycombinator.com/item?id=75126 Clojure is probably too new to find many companies using it. They do have a jobs page, though: http://clojure.org/Jobs http://clojure.org/Jobs
