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.

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.
