11. Eco Nuts
A detergent company, Eco Nuts looked to be a good business when its owners made the pitch of $175,000 for a 15% part in the business. The sharks believed that the pitch was incomplete even though they were interested in the business. Ultimately, no deal was made. However, while Eco Nuts was earning $250,000 before the show, some time after it aired, the company was worth over a million dollars.
