Dan Greiner

Dan and his wife live between their two houses in Philadelphia and Chicago. Both houses are luxurious and expensive. They are convenient as well, as the one in Philadelphia is close to the QVC studio and her products are shipped from Chicago. The couple do not have any children as of yet.

The relationship between the “warm-blooded shark” Lori Greiner and her husband Daniel turns the saying “behind every successful man is a woman” on its head. At the start of her business career, he quit his job at the Bell & Howell Corporation to work for her wife’s fledgling company. He was there to provide support and necessary inputs when she came up with an intricate plastic box to organize earrings in 1996, her very first successful invention. She later patented it and made a deal with J.C. Penney before the holiday season. Within two years, the product made her rich.

Dan was an integral part of her growing empire when the QVC network called in 1998. She began to host the Clever and Unique Creations Show on the shopping channel, earning herself the nickname “The Queen of QVC”. Her incredible rise garnered attention of the US TV series Shark Tank’s show runners. She joined the show as one of the sharks (investors) in 2012. Till date, Lori has made some of the most profitable investments in the show, including in a company called Scrub Daddy that produces a texture-changing household sponge (it becomes stiff in cold water and soft in warm water).

Winning a bidding war against her fellow sharks Kevin O’Leary and Daymond John, Lori bought 20% equity in the company from its owner Aaron Krause for $200,000. The product line’s total revenue surpassed $50 million in January 2017, effectively making it the most successful product in the history of the show. Dan, alongside Lori, has made several appearances on the spin-off series ‘Beyond the Tank’.
