K9 Mask has never published a net worth, and no verified figure exists for the company today. The last confirmed valuation came from the Shark Tank floor on November 20, 2020, when founders Kirby Holmes and Evan Daugherty shook hands with Daymond John on $200,000 for 40% of their business. That priced the company at $500,000. The deal never closed, so the founders kept every share, and K9 Mask is still selling dog air filter masks in 2026.
What is K9 Mask worth today?
Nobody outside the company knows. Good Air Team LLC, the Austin, Texas business behind the K9 Mask brand, is privately held. Texas LLCs don’t file public financial statements, and the founders have not released sales or profit numbers since the show aired.
What does exist are two real valuations, both set in the same hour of television. Holmes and Daugherty priced the company at $1 million when they asked for $200,000 in exchange for 20%. After the back and forth, Daymond John’s 40% for the same money priced it at $500,000.
That $500,000 is a snapshot of one moment, not a running total. It reflects what a single investor thought a business with roughly $200,000 in lifetime sales was worth in late 2020.
Two valuations sit on the record for K9 Mask: $1 million at the ask, $500,000 at the handshake. Both are from November 2020, and neither was ever tested by an actual investment.
If you want a rough sense of the range, work from what is known. The business sold more than $250,000 of product in its first 18 months on about $17,000 of startup money, and it has kept trading for almost six more years with no outside investment. Small direct-to-consumer brands are bought and sold on a multiple of yearly profit rather than revenue. That points to a six-figure company rather than a multi-million one, and to a number that swings with how bad the wildfire season is. Without published profit figures, it stays an estimate.
What happened in the K9 Mask Shark Tank pitch?
The founders walked in wearing air filter masks themselves and asked for $200,000 for 20% of the company. It was Season 12, Episode 6, it aired on ABC on Friday, November 20, 2020, and 4.29 million people watched. That season was filmed inside a sealed production bubble at the Venetian in Las Vegas because of the pandemic.
The panel that night was Mark Cuban, Kevin O’Leary, Lori Greiner, Daymond John, and guest shark Blake Mycoskie, the founder of TOMS.
They liked the idea more than the numbers. Cuban praised the product but said the sales were too small and went out. Greiner thought the market was too narrow. O’Leary passed without a counter. Mycoskie, who has four dogs of his own, admired the mission but stopped at the cost of making the mask, which the founders explained was high because every unit is sewn in Dallas.
Daymond John already had pet products in his portfolio, and he made the only offer: $200,000 for 45%, framed as leaving the founders in the majority. They countered at 30% and he turned it down. They came back with 40%, and he took it. The company’s own Shark Tank page still lays out the exchange line by line.
| Deal point | Number |
|---|---|
| Asked for | $200,000 for 20% |
| Valuation at the ask | $1 million |
| Daymond’s opening offer | $200,000 for 45% |
| Founders’ counter | $200,000 for 30% (rejected) |
| Handshake on air | $200,000 for 40% |
| Valuation at the handshake | $500,000 |
Did the Daymond John deal ever close?
No. The investment was never completed, and no change of ownership has ever been announced. A handshake in the tank is an agreement in principle, not a signed contract. After filming, both sides run due diligence, and a deal can end right there. This one did.
The upside for Holmes and Daugherty is that they kept 100% of Good Air Team, which means they also kept 100% of whatever it is worth. The cost is that everything built after 2020 had to happen without the $200,000 and without the retail contacts that came attached to it. For a small brand trying to get onto pet store shelves, those contacts were arguably the bigger half of the offer.
What are the K9 Mask founders worth?
Neither founder has published personal financial details, so there is no reliable figure for either of them. What can be said is structural. Kirby Holmes and Evan Daugherty are cousins from Austin who started the company together in 2019 and still hold it between them. Because no outside investor ever bought in, their combined stake is the entire business. No shark sits on the ownership list taking a cut, and no funding round has diluted them. That is a cleaner position than most founders who appear on the show end up with. It also means no outside cash ever arrived to speed things up.
How much money has K9 Mask actually made?
The verified sales numbers all come from the early years. The founders put $7,000 of their own money in, then ran a Kickstarter campaign from March 4 to April 1, 2019 that brought in $10,725 from 175 backers against a $10,000 goal.
That $17,000 or so turned into more than $250,000 in revenue across the first 18 months. At the time of filming, lifetime sales sat near $200,000, and that is the number that made most of the panel hesitate. It proved people would buy the thing. It did not prove the market was big.
Nothing has been published since. Demand for a product like this is spiky rather than steady. Orders climb when wildfire smoke drifts over a city, when a dust storm rolls through, when ash falls after an eruption, and then they settle again. A brand with that shape can have a strong year and a quiet one back to back, which is part of why a single net worth number was never going to mean much.
Is K9 Mask still in business in 2026?
Yes. The online store is live and taking orders, and the company has kept publishing new material through 2026, including wildfire preparation guides during the summer fire season.
The product line has grown into two filter types. Extreme Breathe pairs an N95-grade layer with activated carbon and targets the fine particles in wildfire smoke and heavy pollution. Clean Breathe uses activated carbon on its own and handles bigger particles like dust, pollen and lint. Both slot into the same reusable mask, which has adjustable straps and an exhale valve so a dog can pant normally.
The masks are still made in Dallas. The filters have been tested by Blue Heaven Technologies in Louisville, Kentucky under ISO 16890, a standard lab test that measures how much fine dust a filter traps. There is a version for people as well.
Kirby Holmes still fronts the business. He gave the keynote at the Austin Small Business Expo in October 2025 and launched a podcast about dog health in poor air quality the same month.
What a K9 Mask costs now
Masks come in small, medium, large and extra large, and every one ships with three filters.
| Product | Price |
|---|---|
| K9 Mask with three Extreme Breathe filters, blue | $49 |
| Same mask in black, red, pink or orange | $59 |
| Extreme Breathe filter refills, five-pack | $25 |
| Clean Breathe filter refills, five-pack | $25 |
| Clearance masks with minor scratches | from $39 |
A first purchase runs $49 to $59, and a season of replacement filters adds another $25. The price has come down since the show, when every color cost $59.
Frequently asked questions
How much is K9 Mask worth in 2026?
There is no published figure. Good Air Team LLC is private and releases no financials. The most recent confirmed valuation is the $500,000 implied by the on-air deal in November 2020, and that deal was never completed.
Did K9 Mask get a deal on Shark Tank?
Yes, on air. Daymond John offered $200,000 for 45%, the founders countered at 30%, and they settled at 40%. The agreement did not survive due diligence, so the money was never invested.
Is K9 Mask still in business?
Yes. The company is still selling dog air filter masks in 2026 from its own online store, and it has kept publishing new material through the summer wildfire season.
Who owns K9 Mask?
Kirby Holmes and Evan Daugherty, cousins from Austin, Texas. They started Good Air Team LLC in 2019 and kept full ownership between them because the Shark Tank investment never closed.
How much does a K9 Mask cost?
$49 for the blue mask with three filters, or $59 in black, red, pink or orange. Five-packs of replacement filters are $25. Clearance masks with cosmetic marks start at $39.
Conclusion
K9 Mask has no confirmed net worth. The hard numbers on the record are a $1 million asking valuation, a $500,000 valuation from the November 2020 handshake with Daymond John, and more than $250,000 in revenue over the first 18 months of trading. That deal never closed, so Kirby Holmes and Evan Daugherty still own the business outright and still run it from Austin. Treat any specific figure for today as an estimate, because the company has never published one.
