As we mentioned before, not all rejected Shark Tank ideas become failures. One success story from Shark Tank is CoatChex. The innovative concept behind CoatChex was developed by entrepreneur Derek Pacque. His business is a ticketless coat check system that makes checking coats and other valuables at events simple and quick.
This idea impressed the Sharks on Shark Tank, and Shark Mark Cuban offered Pacque $200,000 for a 33 percent stake in the company. Pacque turned him down and left the show without a deal. Since being on the show, CoatChex has been used at events like Mercedes Benz Fashion Week and even the Super Bowl.
