It's usually mostly projects done by small teams, even if the projects themselves may be large.
I would use Lisp on projects with many programmers, I'd imagine management to be a mess unless everyone is as skilled as you. Sadly languages like Java/C#/Python let everyone contribute are popular because they allow easily swapping out programmers as long as you retain an "architect" or two, and companies usually don't like dependence on anyone, but if you're the "founder" and initial coder, you can use any language you like.
