From $0 to $220 Million: The Scrub Daddy Success Story — How One Smiley Sponge Built a Cleaning Empire
When Aaron Krause invented a simple sponge with a smiley face, he had no idea it would become one of the most successful products in the history of Shark Tank — eventually growing into a cleaning empire with over $220 million in sales, 160+ products, and a fanbase that treats shopping for sponges like opening presents on Christmas.
This is the story of Scrub Daddy — the most iconic sponge in America, and perhaps the greatest cleaning product innovation of the 21st century.
💡 The Birth of Scrub Daddy: Innovation From the Garage
Aaron Krause didn’t begin his journey intending to disrupt the cleaning world. In fact, he started in car detailing.
As a teenager in Wynnewood, Pennsylvania, he began washing cars for $10 each. After college (with a psychology degree from Syracuse University), he decided to pursue this work full-time — to his family’s disappointment.
“My mom cried, my grandmother wanted to disown me,” Aaron recalled.
But Aaron’s passion for tinkering and improving things showed early. He invented a patented buffing pad for polishing cars — a creation that gave him his first taste of business and his first lesson in material science: polyester urethane foam.
That material would later evolve into FlexTexture®, the star ingredient in Scrub Daddy’s rise to fame.
🧼 From Auto Shop Waste to Kitchen Gold
Fast-forward to 2008, when Aaron sold his buffing pad business to 3M. A box of experimental foam scrubbers — forgotten and unused — sat in his factory.
Three years later, his wife asked him to clean outdoor furniture. The traditional sponge scratched the paint. Frustrated, Aaron grabbed one of his old foam scrubbers. What happened next was revolutionary.
🌡️ Cold water made it firm for scrubbing tough stains.
🌡️ Warm water made it soft for gentle cleaning.
🧽 It rinsed clean.
😁 And he noticed: the circular sponge, with two holes and a rough edge, looked like a face.
The smiley face design wasn’t just cute — it was genius. The eyes allowed users to grip it easily, and the mouth cleaned both sides of utensils in one swipe.
That night, Aaron did the dishes with his newfound sponge and had an epiphany. He modified the shape, added a smile, and turned a forgotten prototype into a product that felt magical.
🦈 Shark Tank & Lori Greiner: A Deal That Changed Everything
Aaron initially tested Scrub Daddy in local supermarkets and had some success. A feature in the Philadelphia Inquirer led to a flood of interest — and then came QVC.
Aaron’s sponge sold like wildfire on the home shopping network, and the momentum gave him the confidence to apply for Shark Tank.
He went in seeking $100,000 and walked out with $200,000 for 20% equity from Lori Greiner — who saw the same magic in Scrub Daddy that Aaron did.
“When you and Lori looked at each other,” a producer later said, “everyone knew you were going to be together.”
Lori leveraged her experience with retail and TV to propel Scrub Daddy into Walmart, Bed Bath & Beyond, Target, and more. The product went from a clever tool to a national sensation.
