Plot Synopsis

This reality series gives budding entrepreneurs a chance to make their dreams come true and become successful -- and possibly wealthy -- business people. But the entrepreneurs must first try to convince five tough, multi-millionaire tycoons to part with their own hard-earned cash and give them the funding they need to jumpstart their ideas. The tycoons try to negotiate a deal with the entrepreneurs until all five of them say "I'm out." For the first two seasons, the business sharks were: real-estate mogul Barbara Corcoran; infomercial industry pioneer Kevin Harrington; technology innovator Robert Herjavec; fashion icon Daymond John; financial expert Kevin O'Leary. In season 2, Mark Cuban and Jeff Foxworthy joined the show as guest Shark investors, with Cuban replacing Harrington as a regular investor in Season 3. Plus, retail-product inventor Lori Greiner, "The Queen of QVC," joined the program in Season 3 as a guest shark investor and in Season 4 she joined the series as a regular investor. During the third season, the Sharks offered over $6.2 million of their own money in investment deals to bankroll a creative array of innovative entrepreneurs, after investing $5 million (Season 1) and $4 million (Season 2) in previous seasons.
