TRUFIT

TRUFIT Customs makes custom-fit sports mouthguards along with related dental products like night guards, using precise fitting so athletes get protection that actually conforms to their teeth. The company was founded by Matthew Hall, who built it around the idea that boil-and-bite mouthguards are a poor compromise and that athletes deserve professional-grade custom fit at a more accessible price and process.

Matthew came into Season 16 asking for 750,000 dollars for a 5 percent stake, a confident valuation backed by traction with athletes and teams. Guest shark Rashaun Williams, who has a sports and investing background, engaged with the pitch. The two worked out a deal with Rashaun taking a larger equity share than the original ask in exchange for his investment and connections in the sports world.

TRUFIT stood out because mouthguards are a universal need in contact sports and the custom-fit angle offered a clear upgrade over the cheap molded versions most athletes use. The founder's focus on serving real teams and athletes, rather than just consumers, gave the business credibility and a path into organized sports that the sharks could see scaling.

After airing, TRUFIT reported a sharp jump in sales and expanded its reach into organized sports, becoming a mouthguard partner for professional and collegiate programs. The company broadened its product line into night guards and other dental trays and built distribution that let customers get fitted through dental partners rather than only at home.

As of 2026 TRUFIT Customs is still operating and selling through its official site at trufitcustoms.com. The brand has continued partnering with sports leagues and teams and has worked with a large dental lab network to make fitting more accessible. It returned for a Shark Tank update segment, reflecting its continued growth as an active custom-mouthguard business.
