Examples of how LISP was adapted for a business task

Question

Nearly every LISP enthusiast claims that one of the key benefits of a language is that it can be adapted to a problem rather than a problem adapted to the language. I am looking for real examples of how this is possible in the field of simple business software or web applications. Is there anything else besides DSL? Any fairly complicated / non-obvious examples of them?

PS: why can't I use the "problem" in the title?

Here is a list of lisp applications on Paul Graham's site. The page contains products / companies from various fields.

Among other things, Yahoo! Store is WAS lisp (based on a Graham product acquired by Yahoo). Thanks Robert for pointing out.

I think the following stackoverflow post might interest you: What is lisp used today and where do you think it is going?
