Who’s the most successful shark? That takes some investigation, but to us it seems clear Lori Greiner has the top most successful deals in Shark Tank history to date. Remember the Simply Fit board, the little board that looks like a miniature surf board. You step on and whittle your waist. That mother daughter duo ranks as #2 in most successful products in Shark Tank History amassing $160M in total retail sales. Greiner created an infomercial and mass marketing “blitz” that resulted in everyone wanting to step on to twist the night away. My calculations come in at 4 million boards sold. And the funny, not so funny Squatty Potty. The front of toilet stool, no pun intended, that helps you Poop. Fellow sharks laughed, but Greiner saw the merit, invested and today that pooping stool has done $164M in retail sales and according to my calculations that’s 5 million Squatty Potty’s sold. The proof is in the pooping. I think I need to get one. Also, her investment in a yellow smiley face sponge that turns hard in cold water and soft in hot tops the list at $200M retail sales with 93M Scrubdaddy’s sold. Last shared the Scrubdaddy has morphed into 48 new products and SKU’s. It’s sold in over 30,000+ Retail stores, major mass retailers like Wal Mart, Bed Bath & Beyond, and Target. Most grocery chains and Drug stores nationwide and sold in 17 countries around the world. Now that’s Crowns Scrubdaddy King under the Queens realm of deals and in the Shark Tank kingdom.
