Which Shark Tank investor is known by the nickname “Queen of QVC”?

Lori Greiner is known by the nickname “Queen of QVC.”

The nickname refers to Greiner's long and successful career selling products through QVC, the American home-shopping television network. She became especially associated with demonstrating practical consumer inventions and explaining their use in short, persuasive presentations.

Greiner's own breakthrough product was a jewelry organizer that could display and store earrings. The product's commercial success helped her build a broader portfolio of inventions and eventually led to hundreds of patents and retail placements.

Her QVC identity remains distinct from the nickname “Mr. Wonderful,” which belongs to fellow investor Kevin O'Leary. Greiner later brought the same product-focused approach to Shark Tank after joining the show's regular cast in season three.
