Yes, the main benefit of being on the show is the publicity (as long they don't skewer you). It seems that at least once per show there is a company that has little real need for funding, and I'm sure they went on there with the specific intent of getting the publicity and little else.

One peculiar thing that I noticed in those statistics is that Daymond John was leading in terms of deals. I was sure he would be dead last...I rarely see him do deals.
