Singtrix – INC
If you’re a fan of Shark Tank, you may remember John Devecka and Eric Berkowitz. They are the founders of Singtrix, the New York-based maker of a voice-enhancing karaoke machine that promises that even Mr. Wonderful can sound like an American Idol contestant. On season six of the show, in 2014, the co-founders came out dressed like 1980s-era roadies, belting harmonies and flaunting Singtrix’s flashy audio effects.
