Scrub Daddy was the sponge company that received Lori Greiner's Shark Tank investment.
Aaron Krause created Scrub Daddy, a textured cleaning sponge whose material changes firmness in hot and cold water. Its smile-shaped face also functions as a practical design: the mouth can clean utensils, while the eyes help hold fingers during use.
Krause presented the product on Shark Tank in 2012. Lori Greiner offered to invest in exchange for equity, and the partnership helped place Scrub Daddy in major retail channels. The product became one of the show's best-known success stories.
The brand is sometimes confused with generic smile-shaped sponges, but Scrub Daddy refers specifically to Krause's company and product line. Its commercial appeal came from combining a recognizable shape with a demonstrable material feature.
