A clear look at what the brand is actually worth, and what happened to it after the show.
There is no public net worth figure for Grease Monkey Wipes, and any site that gives you an exact dollar amount is guessing. Here is what can actually be checked: it was a small cleaning-wipe brand that landed a deal on Shark Tank in 2010, grew fast, and then sold to Beaumont Products in November 2014 for an amount that was never made public. The founders kept the sale price private, so a precise valuation simply does not exist.
That is the honest version. Below is the full story, the deal, the growth, the sale, and who built it, so you can see where every number comes from.
So what is Grease Monkey Wipes actually worth?
Nobody outside the deal knows, and that is the real answer. The company was privately held, the 2014 sale price was undisclosed, and the founders have stayed quiet about money ever since. So any “net worth” number you see floating around is made up.
What we can anchor to are a few verified figures from the brand’s early days. When the founders pitched on Shark Tank in early 2010, they had sold about 7,600 wipes at roughly a dollar each, for around $7,400 in gross sales. That is a tiny startup, not a multi-million-dollar empire.
Short version: the brand was real and successful enough to get bought, but no trustworthy public figure tells you what it was worth.
What are Grease Monkey Wipes?
Grease Monkey Wipes are heavy-duty, citrus-based cleaning wipes made to pull grease, oil, and grime off your hands when soap and water are not around. The formula is non-toxic and plant-based, which is a big part of why people liked using them on skin.
The idea came from cycling. The founders were on a long ride and got grease all over their hands fixing a bike mid-route, with no good way to clean up. They built a wipe to solve that one problem, then realized it worked on far more than bikes. Mechanics, painters, and home cooks all found uses for them.
The Shark Tank deal
Grease Monkey Wipes appeared on Shark Tank Season 1, Episode 113, which first aired on January 15, 2010. The founders asked for $40,000 in exchange for 40% of the company.
Not every Shark was sold. Some felt the formula was too easy to copy since there was no patent, and others thought the market was already crowded. But two investors liked it enough to jump in together: Barbara Corcoran and Robert Herjavec. They took the deal at the original ask, $40,000 for 40%, split between them.
The TV exposure hit right away. The brand’s website traffic jumped by about 4,700% after the episode aired, which is the kind of spike that turns a tiny side project into a real business almost overnight.

What happened after Shark Tank
This is where the brand really took off. After the episode aired, Grease Monkey Wipes grew its retail footprint from about 40 stores to more than 500, sold over 200,000 units, and saw sales climb by more than 700%.
Over time, Tim Stansbury bought out both Sharks and his co-founder, turning the company into a one-person operation. Then, in November 2014, he sold the whole brand to Beaumont Products, a maker of eco-friendly consumer goods. The sale price was never disclosed, a detail confirmed in the Shark Tank Blog update on the company.
Because the exit price stayed private, that 2014 sale is the closest thing to a real valuation, and even that number is sealed.
Who are the founders?
Grease Monkey Wipes was created by Tim Stansbury and Erin Whalen, two cyclists who turned a messy-hands problem into a product. Stansbury earned a bachelor’s degree in marketing and an MBA from Oklahoma State University.
After selling the brand, Stansbury started Cat5Elite, a cycling-themed clothing company, and later moved into product strategy work in Austin. Both founders have kept a low profile since the show, which is a big reason no personal net worth figures for them exist either.
Can you still buy Grease Monkey Wipes?
Yes. The brand still exists under Beaumont Products and the wipes are sold online and in stores. People use them well beyond the garage, for removing paint, cutting kitchen grease, and general cleanup where you want something gentle on skin, as this Apartment Therapy review of household uses shows.
So the product outlived the headline. The founders moved on, the ownership changed hands, but the wipes themselves are still on shelves more than a decade after that Shark Tank pitch.

Conclusion
Grease Monkey Wipes has no public net worth, so treat any exact figure as a guess. What is real: the founders took a $40,000-for-40% deal with Barbara Corcoran and Robert Herjavec on Shark Tank in 2010, grew to 500-plus stores and 200,000-plus units sold, then sold the brand to Beaumont Products in 2014 for an undisclosed price. A good answer here is the honest one: a small idea that scaled, then exited quietly.
