Shark Tank is an American business reality television series that premiered on August 9, 2009 on ABC. The show is the American franchise of the international format Dragons' Den, which originated in Japan as Tigers of Money in 2001. It shows entrepreneurs making business presentations to a panel of five investors or "sharks," who decide whether to invest in their company.
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 valuation of their company, product, or business model. Some of the investors are usually kindhearted and try to soften the impact of rejection, like panel member Robert Herjavec, 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.
