Now, for the the biggest "Shark Tank" success of them all: Scrub Daddy. Aaron Krause stepped into the tank in season four like a seasoned infomercial pitch man. His lemon-scented, smiley-shaped sponge is made from a material that makes it notably more durable, hygienic, and effective than the average sponge. John told us earlier this year that Krause's pitch was his favorite of the entire series — but QVC queen Greiner was once again the perfect fit. She made a deal with Krause for $200,000 in return for a 20% stake.
When Krause pitched his company, he'd struggled to reach $100,000 in sales over 18 months. Since "Shark Tank," Scrub Daddy has brought in well over $18 million. It's a staple product on QVC and appears in retail stores like Bed Bath & Beyond and Walmart.
"Who would've guessed that a simple sponge would be the greatest 'Shark Tank' success story of all time?" says In the Shark Tank's Baumgarten.
