The team stepped onto the carpet in Season 10, Episode 20 in the episode that aired April 21, 2019. Somnifix, the mouth tape, pitched in the Health & Wellness category, one of 70 health & wellness businesses to brave the Tank across all 17 seasons.
The ask was $500,000 for 10% of the company, an implied valuation of $5M.
Mark Cuban made the deal at $500,000 for 20% equity. That priced the company at $2.5M, a haircut from the $5M the founders walked in asking for, which is how negotiations in the Tank usually go.
Season 10 saw 92 pitches, and 63 of them closed a deal on air. In the Health & Wellness category overall, roughly 59% of pitches have landed a shark across the show's history.
The full story
Everything to know about Somnifix
SomniFix is a gentle adhesive mouth strip worn over the lips during sleep to encourage nasal breathing and reduce mouth breathing and snoring. Founder Nicholas Michalak developed it after watching his father struggle with sleep apnea and most standard treatments, since he slept with his mouth open. The strip is designed to be hypoallergenic and easy to remove, with a small central vent so wearers do not feel sealed shut.
Michalak pitched in Season 10 asking for $500,000 for 10 percent. Mouth taping was still an unfamiliar idea to many viewers, so part of the pitch was simply explaining the benefits of nasal breathing. Mark Cuban engaged with the health angle and offered the full $500,000 but for 20 percent, double the equity asked, and Michalak accepted that offer from Cuban during the episode.
SomniFix stood out by bringing a then-niche wellness practice, mouth taping, to a mainstream audience with a purpose-built product rather than improvised tape. The clear before-and-after framing around snoring and dry-mouth sleep made the benefit easy to understand, and it rode a growing public interest in breathing and sleep quality that has only expanded since.
Where Somnifix is now
The on-air deal with Mark Cuban did not close after filming, but SomniFix used the exposure to grow its retail and online presence. Mouth taping became a far more widely discussed sleep trend in the years that followed, and the brand benefited from that wave, expanding distribution across major drugstore and big-box retailers as well as international markets.
As of 2026 SomniFix is still operating and selling, both through its own website and through retailers, and it remains one of the better-known names in the mouth-strip category. The product line has stayed focused on its core sleep strips, and the brand continues to position itself around nasal breathing and quieter sleep rather than chasing unrelated categories.
Where to buy Somnifix
SomniFix is widely available on Amazon and the official SomniFix website, and is also stocked by retailers such as Walmart, CVS, and Target. A standard pack of 28 strips generally sells in the mid-teens, which makes it an inexpensive thing to test for a few weeks. If you breathe through your mouth at night, snore, or wake up with a dry mouth, it is a low-cost experiment. Start slowly and stop if it ever feels uncomfortable or restricts your breathing.
