I'm a Shark Tank Fan. Every now and then I am surprised at the approach taken by the shark bait. I guess some people are so busy trying to get their business off the ground they actually don't watch the show, or don't watch it enough, and fall into some basic traps.
If you want to try out for Shark Tank, but want to practice your presentation, I am available, I may even come up with an idea or two to optimize your presentation. Odds are I won't hurt your presentation, but possibly make it better.
