They could market ShaveMate on their own through shavemate.com and specialty retailers like hotels, airport stores and cruise ships, using their tagline, “The future of shaving is here.” This was the most affordable option, costing an estimated $100,000 to produce razors for the initial stock, displays and promotions, but it would take a while to build the brand and increase sales.

Finally, they could initiate a two-pronged marketing attack for about $1 million, looking for a big splash with a low-cost specific public relations effort to put ShaveMate in front of print editors and TV producers. Then they could begin a national, as-seen-on-TV campaign on cable channels to educate consumers via two-minute commercials on how their product could simplify shaving. The goal would be to have a well-known spokesman promote the razors.

THE DECISION The Tomassettis picked the two-pronged attack. All new revenue would feed the marketing beast, and the brothers hoped to build recognition quickly.

The blitz to send out samples and promotional material paid immediate dividends: ShaveMate Diva 6 appeared in the Love That section of O, the Oprah Magazine. Local news stations tested ShaveMate razors on the air. “Live With Regis and Kelly” featured Diva.

Producers of the Discovery Channel program “PitchMen,” heard about ShaveMate, and in February 2009, they invited the brothers to California to try out for the show. Billy Mays, the face of OxiClean, and Anthony Sullivan, also a pitchman, were the hosts who would decide which inventors had a marketable product.

“When we auditioned, they literally went crazy,” Louis recalled. “They said this is a monster hit.” The brothers would be included on the show and Mr. Mays and Mr. Sullivan were both going to be spokesmen. Mr. Mays said, according to the Tomassettis, that he loved the product so much he was going to shave his beard with a ShaveMate on national TV. He would be the face of ShaveMate.
