I'm hooked!
Never even heard of it until a few weeks back, and now my DVR is set to record all episodes.
Basically, there are 5 "sharks". They are 5 very rich people sitting in front of you in chairs. You pitch your product/business to them. You ask for an amount, generally for giving them some equity in your business. They will be brutal and ask you questions. Then they are either in or out.
Mark Cuban is great. He is the owner of the NBA's Dallas Mavericks. He's brutally honest, but fair, and generally friendly. Then Kevin O'leary, a billionaire who makes Cuban look friendly. If you don't accept his offer, he'll quickly tell you "You're dead to me".
Cool watching some of the small business, growing business, trying to expand. And outside the humor, the feedback from the sharks is interesting.
