1. Chef Big Shake
According to many different sources, Chef Big Shake is the most successful Shark Tank reject. Even though no shark was willing to offer $200,000 for a 25% stake, the fame brought by the airing of the show led to other investors pouring their money into the business, which allowed sales to increase up to $5 million. In fact, Mark Cuban even stated once that one of his biggest mistakes on the show was passing up on this idea.
