List of Shark Tank episodes
"Shark Tank" is an American reality television series produced by Mark Burnett. The show features a panel of investors called "sharks," who decide whether to invest as entrepreneurs make business presentations on their company or product. The sharks often find weaknesses and faults in an entrepreneur's concept, product, or business model. Some of the investors try to soften the impact of rejection, like panel member Lori Greiner, while others such as Kevin O'Leary can be "brutal" and show "no patience even for tales of hardship." The sharks are paid as cast stars of the  show, but the money they invest is their own. The entrepreneur can make a handshake deal (gentleman's agreement) on the show if a panel member is interested. However, if all of the panel members opt out, the entrepreneur leaves empty-handed. In 2015, a companion spin-off series called "Beyond the Tank" premiered, which follows up on some of the businesses that have appeared on the show. In this spin-off series it was revealed that sharks can still make a deal with a business that was rejected in the "tank". "Shark Tank"s twelfth season premiered on October 16 , 2020.
