Scrub Daddy

Ever wonder how much money the people who invented the sponges you wash your dishes make? Aaron Krause appeared on Shark Tank in 2012 and his invention Scrub Daddy has since become the most successful product from Shark Tank. The Scrub Daddy is a reusable sponge in the shape of a smiley face that is made from a material that is more durable, hygienic and effective than your average sponge. Before Shark Tank, Krause struggled to make $100,000 in 18 months, after his appearance the Scrub Daddy has made over $50 million in sales.
