Spinbrush: John Osher. The Electric Toothbrush That Sold for $475M

John Osher, the serial entrepreneur behind the Spinbrush, recounts his journey of multiple successful ventures. Beginning with an earring store in college, Osher learned the importance of pricing based on market value rather than cost. He later transitioned through various businesses, including energy-saving devices and baby products like the Rainbow Toy Bar, before finding success in the toy industry with Cap Toys and the spinning lollipop, SpinPop, eventually selling to Hasbro. His most notable creation, the Spinbrush, emerged from his expertise in small motors and batteries gained from the SpinPop. Osher strategically approached Procter & Gamble, leading to an acquisition and the Spinbrush becoming a best-selling toothbrush.
