SignalVault is a protector for credit cards to prevent them from being remotely scanned; a solution to crowd-hack-attacks on credit and debit cards. The inventor of SignalVault, Chris Gilpin, launched the company with winnings from a lottery ticket in 2013. Two years later, Gilpin pitched his business on Shark Tank (September 2015, Season 7). He made a deal with cyber security expert Robert Herjavec and retail queen Lori Greiner -- $200,000 for 25 percent equity.
After Shark Tank, Greiner brought Gilpin on QVC. In less than ten minutes, they sold nearly 5000 SignalVault cards. (At about $30 apiece that means $150,000 -- three-quarters of their investment.) Greiner has also helped to redesign the packaging and get the products in stores including Bed Bath & Beyond and Staples. SignalVault is also available on Amazon.The BEST SALES on Amazon NOW ]
