The owners of a North Texas startup that supplies an inventive men's razor dove into the Shark Tank on November 3 and swam away with a $300,000 investment.

Husband-and-wife team Patrick and Jennifer Coddou, owners of Supply, pitched their product to the panel of five investors on ABC's Shark Tank and hooked one of them, tech millionaire Robert Herjavec. In exchange for his $300,000 investment, Herjavec received a 15 percent stake in the four-year-old company.

"It was a surreal experience for us just making an appearance on the show, but we couldn't have been more pleased with the outcome," Patrick Coddou, CEO of Supply and a Houston native, says in a release. "I knew we had shaped a brand that sets itself apart, not only because of the innovative razor design but also the kind of standard we hold ourselves to, and I'm glad that resonated with Robert and the rest of the Sharks."

Herjavec battled against fellow Shark Kevin O'Leary to invest in Supply, but the Coddous wound up accepting Herjavec's offer.

Patrick Coddou, an engineer-turned-entrepreneur, launched Supply in 2015 from his home in Fort Worth.

The single-blade Supply razor cuts hairs at the skin level, compared with multiblade razors that cut hairs under the skin level, which causes irritation. The startup's other offerings include men's skincare products, travel cases, Dopp kits, marble shaving bowls, shaving cream, and shaving brushes.

Supply ranks as the most popular single-edge razor ever sold through fundraising platform Kickstarter, collecting more than $250,000 in 45 days. Today, Supply delivers single-edge razors to customers in 43 countries.
