Flaus Update | Shark Tank Season 15

Only 3 out of 10 Americans floss every day, which leads to serious dental problems over time. To help fix this, Samantha Coxe created Flaus, an electric flosser that makes cleaning between teeth faster and easier. It kept mouths healthier while giving people a simple alternative to string floss. Did the sharks think it was worth backing? Let’s find out in our Flaus update and pitch recap.

If you’re short on time, here’s a quick overview of what happened to Flaus after Shark Tank.

Samantha pitched her electric flosser, Flaus, on Shark Tank Season 15, seeking $250,000 for 5% equity. After her pitch, she received three offers from the sharks and was left with a deal from guest shark Candace Nelson for $250,000 for 8% equity.

In terms of a Flaus update, the company earned $1 million in first-year sales and raised over $4 million. Further, they expanded to more than 150,000 customers, launched stronger floss heads, and introduced a dental ambassador program.

Shark Tank Flaus Pitch

• Entrepreneur: Samantha Coxe
• Business: oral hygiene solution
• Ask: $250,000 for 5% equity
• Result: $250,000 for 8% equity
• Shark: Candace Nelson 

Samantha started her pitch by highlighting the questions dentists usually ask their clients. She argued that oral health was important, but only 30% of Americans floss daily.

She introduced Flaus as the world’s first electric flosser, designed to make flossing as simple as brushing with an electric toothbrush.

Users could snap on a recyclable floss head, power it up, and choose a speed setting with up to 18,000 sonic vibrations per minute.

The device moved smoothly between tight teeth, while its ergonomic design made it easy to reach the molars without putting a hand in the mouth.

Samantha then asked which shark was ready to toss out traditional floss and team up with Flaus. The sharks were impressed by her product’s design and concept.

After trying the product, guest shark Candace Nelson particularly enjoyed the peppermint-flavored floss and inquired about other flavor options, which Samantha confirmed were in development.

Candace probed further to assess Flaus’s long-term viability. Samantha explained the device costs $99 online, with a manufacturing cost of $25 per kit, allowing a 75% gross margin.

The Flaus kit includes the device, charger, cable, and 45 floss heads. It offers a convenient and potentially cost-saving alternative to traditional flossing.

She added that a 3-month subscription for $15 (or $5 monthly) keeps you stocked with 90 floss heads.

Daymond John then inquired about their retail presence. Samantha explained that since Flaus’ devices were new to the market, establishing retail connections was challenging. Therefore, she opted to sell directly to consumers.

The business had generated $900,000 in sales in the last 12 months, translating to a healthy 33% gross profit of $300,000. While not yet profitable, this first-year performance impressed Candace.

Kevin asked about Flaus’s customer acquisition cost. Samantha said that the company acquired its customers for $38 per order. The return on ad spend (ROAS) was 3x the expenditure.

Even though the company had just under a million dollars in sales, it had no public relations or publicity expenses.

Candace further inquired about the money Samantha had raised for Flaus. Samantha explained that she had raised $3.5 million because the device was a consumer electronic and the business was capital-intensive.

The fundraising dated back over two years and was closed at a valuation of $8 million.

Lori Greiner described the Flaus product as a mousetrap for consumers. She preferred traditional flossers and didn’t think Flaus was worth the money, so she dropped out.

Mark Cuban shared in Lori’s sentiments and opted out, saying that electric flossers weren’t a good fit for him.

Kevin O’Leary was impressed but did not like Samantha’s offer. He countered with a new offer of $250,000 for 5% equity and a royalty of $2.50 until he recouped $750,000.

Candace countered Samantha with $250,000 for 8% equity and brand-building expertise, prompting Kevin to lower his equity demand to 3%.

Daymond John offered $250,000 for 10% equity and added that he could help Samantha get a licensing deal.

Overwhelmed by the offers on the table, Samantha tried to counter Candace’s deal, but Candace declined.

In the end, she accepted Candace’s original offer and walked away with a deal. Did Samantha make the right choice? Find out in our Flaus update.

Shark Tank Flaus Update

Our Flaus update found that there is no public information that supports whether Candace eventually put money into the business.

But we do know that in the weeks following the episode, Flaus quickly sold out all of its electric flossers.

In June 2024, the company had already switched to a pre-order system with a 20% discount. Demand from the national TV exposure gave them a big boost, and early traction was clear.

In December 2024, Samantha appeared on the Female Founder World podcast, where she said that Flaus had hit $1 million in its first year of sales and raised over $4 million to date.

She spoke openly about her struggles, including faulty production runs, copycat competitors, and even losing a co-founder, but emphasized how determined she was to keep moving forward.

Earlier that fall, in September 2024, she was also featured on the official podcast of the American Dental Hygienists’ Association.

There, she described the early product-development challenges and how she worked through them.

At the time of this writing, Flaus had grown its customer base to more than 150,000 people. The company also launched a new product feature: 200% stronger woven floss heads.

Their website highlighted new offers such as free shipping, a 30-day money-back guarantee, and an extended warranty.

They also rolled out a dental ambassador program, offering discounts to dental professionals to help build industry support.

Meanwhile, Samantha has become a strong voice in entrepreneurship. She spoke on the Venture Everywhere podcast in April 2025 about using her legal background to identify product-market fit and why she prioritizes first-order profitability as a founder.

She has also made clear that leaving her law career to build Flaus was not easy. Samantha spent two years funding the company on the side before going full-time, and that commitment paid off with rapid growth.

You can buy the Flaus electric flosser for $79 from the Flaus website and join its subscription service to receive replacements on a regular basis.

You can also follow their journey and see updates on Instagram.

Samantha’s future looks bright, and we can’t wait to see what it holds for her in our next Flaus update.
