They sell an enterprise version of Julia for $1500 per year. The main things you get are support, MS Excel integration, and a non-GPL license. They also offer consulting, training, and a few other flavors of Julia (large scale server based gets its own edition).
I'm sure the main draw will be companies that don't want to be stuck with a GPL license in their product.
