Lori Greiner is the Shark Tank investor associated with the television shopping network QVC.
Greiner developed her first major product, a jewelry organizer, in the 1990s. The invention led to a retail business and eventually to television appearances on QVC, where her product demonstrations became a major part of her professional identity.
She became known as the “Queen of QVC” because of her success presenting consumer products on the network. Her career there predates her role on Shark Tank and helped establish her expertise in product development, packaging, and direct-response selling.
Greiner joined the regular Shark Tank cast in the program's third season. Viewers sometimes associate her only with Shark Tank, but QVC was an important earlier platform in her business career.
