I knew a company, StorySense, and their main product WhatsTheNumber used Lisp (maybe Scheme?) for the main logic in the back end. One of the founders previously worked at MIT Media Lab. Interestingly enough their competitor, Whoscall, was acquired by Naver. I wonder if they also used Lisp and if LispE is related to that product at all.
