Lori Greiner became a shark on ABC's Shark Tank in its third season, bringing her expertise in retail, product development, and direct-to-consumer sales.

Initially, Lori focused on products that were suitable for her QVC platform, allowing her to leverage her established distribution channels and sales expertise. She looked for innovative, problem-solving products with mass appeal.

Lori has made several highly successful investments on 'Shark Tank,' including Scrub Daddy (a textured cleaning sponge), Drop Stop (a car seat gap filler), and Bantam Bagels (mini stuffed bagels). These companies have achieved remarkable sales figures and brand recognition thanks to her guidance.

Scrub Daddy is one of Lori's most successful Shark Tank investments. She helped the company refine its marketing strategy, expand its product line, and secure placement in major retail chains, resulting in significant sales and brand growth.

Drop Stop, a simple device to prevent items from falling between car seats, also benefitted greatly from Lori's involvement. She helped the company refine its packaging and marketing, leading to increased sales and distribution.

A key advantage Lori offers to her Shark Tank investments is access to QVC, where she can showcase products to a large and engaged audience. This has been instrumental in boosting the sales and visibility of many of her portfolio companies.

Lori continues to invest in new companies on Shark Tank, seeking out innovative products and entrepreneurs with potential. Her reputation as a supportive and strategic investor makes her a sought-after partner.

Lori is known for her ethical approach to investing, focusing on products and companies that she genuinely believes in and that offer value to consumers. She has also voiced her avoidance of business models that exploit or deceive consumers.
