A Simple Household Idea Saved Him From Bankruptcy and Made Billions
At 40, Aaron Krause had run out of money after years of trying to build new automotive products that never really caught on. Some ideas failed, and boxes of unsold inventory began piling up. One leftover piece of foam even ended up in a box marked scrap. That forgotten material later became Scrub Daddy, a simple sponge that grew into a billion-dollar brand and one of Shark Tank’s most famous success stories.
An Entrepreneurial Kid

Growing up in Wynnewood, Pennsylvania, Aaron built a rope-and-pulley system at age 10 to turn off his bedroom lights without leaving his bed. He enrolled at Syracuse University in 1988 and graduated with a degree in psychology. Instead of applying for corporate jobs, he launched a car washing business from his family’s garage. His father gave him one summer to make it legitimate, and the business grew. In 1995, he sold that operation and focused on manufacturing buffing pads through Dedication To Detail.
Bought By 3M

3M purchased Dedication to Detail, and Aaron stayed on as a developer and consultant. He attempted to include a circular foam hand scrubber in the acquisition, but the company excluded it from the deal because executives considered it worthless. The rejected sponge sat untouched for about three years before the product, once dismissed by a Fortune 500 company, was given a second life.
The Scrap Box

By 2011, his wife, Stephanie, asked him to clean the moldy lawn furniture. He grabbed the unused foam from the scrap box and tested it. The sponge cleaned the grimy surface with ease. The same foam was originally developed for car detailing, where it proved scratch-resistant. That moment convinced him that the product belonged in kitchens, not garages.

He cut the foam into a round shape, added two eye holes, and curved the mouth. The eye holes improved grip, and the mouth helped clean utensils. The material changed texture with water temperature, becoming firm in cold water and soft in warm water. The sponge resisted odors and did not scratch surfaces.
The Commercialization of Scrub Daddy

Aaron named the sponge Scrub Daddy and tested it at home before selling it anywhere else. He then invested $150,000 to patent the design and persuaded a friend who owned a small grocery chain to stock it. Standard sponges sold 2 or 3 units per day in the store. Scrub Daddy sold between 200 and 300 units per day in the same location. He demonstrated it in person to shoppers, and the results proved demand was real.
Landing on QVC

Television changed everything. On QVC, Scrub Daddy sold 42,000 units in under seven minutes during its debut. That rapid sell-through caught the attention of major retailers. Walmart, Target, and Bed Bath and Beyond placed orders after seeing the response. A simple sponge suddenly had national momentum.
The Shark Tank Moment

In October 2012, he appeared on Shark Tank’s season 4. He asked for $100,000 in exchange for 10% equity. Several Sharks questioned whether a sponge could stand out in a crowded market. Lori Greiner offered $200,000 for 20%, and he accepted. Within 24 hours of the episode airing, Scrub Daddy generated over $1 million in sales.
Revenue Milestones

The company reached $100 million in revenue by 2014. And fast-forward to 2023: annual sales hit $220 million. Industry reports that the brand’s value exceeds $1 billion. The product is widely cited as one of the most successful investments in the show’s history.
Meet, Scrub Mommy

The introduction of Scrub Mommy in 2014 was a hybrid version that combined the original foam with a traditional sponge layer. Additional products followed, including Scrub Daisy and Power Paste. The company now launches two or three products each year. What started as one single sponge has grown into a cleaning brand.
Off to Dominating the World

Scrub Daddy moved its headquarters to Pennsauken, New Jersey, in 2021. The facility includes a television studio, a warehouse, a retail store, and even a koi pond. In March 2023, the company partnered with Unilever to expand internationally through co-branded products, and plans for European growth are underway. And that’s the story of how a sponge once tossed aside now anchors a global cleaning business built from one everyday frustration.
