2. The Sharks

As we mentioned before, Sharks Robert Herjavec and Kevin O’Leary were originally featured investors on the Canadian show Dragons’ Den. They have been on Shark Tank since it started, along with Daymond John and Barbara Corcoran. For the first two seasons, Kevin Harrington was also a Shark on the show. 

In the second season of Shark Tank, Dallas Mavericks owner Mark Cuban joined the show as a guest Shark. He became a fan favorite and ended up joining the show as a permanent cast member in season 3. The same happened with QVC Queen Lori Greiner, who guested in season 3 and joined the cast in season 4.
