5. Copa Di Vano
Founded by James Martin, Copa Di Vano produced resealable containers which hosted a collection of up to 7 wines. The sharks were very impressed by the product, but James wanted $600,000 for a 30% stake and nothing could change his mind. He even refused to consider ideas the sharks were coming up with such as giving a license of the single serving cup to other wine manufacturers. James left without a deal and then returned later again, with the same results once again. However, despite the fact that he was not able to obtain a deal, James said his company has earned over $25 million in revenue. No wonder he is among the most successful Shark Tank rejects.
