Rabbi Moshe Weiss of St. Louis Park, Minnesota pitched his invention SoundBender, a magnetic sound amplifier that clips on iPads, on Shark Tank in February 2013. He made a deal with Daymond John — $54,000 for 40 percent equity. In November 2013, Weiss and John appeared on a Shark Tank Update and met with The Wish Factory to talk about licensing the SoundBender and adding Marvel’s Avengers characters to the back of SoundBenders. However, on August 28, 2015, Weiss died from heart complications. He was 41.
Daymond John posted a note of condolence on social media and described Weiss as “a man that would bring energy and joy to any room he entered. He would make you smile no matter what was going on in your life. Rabbi Moshe will truly be missed. RIP my friend.” In addition to being an inventor and entrepreneur, Weiss was an educator. He taught at various Jewish schools in the Twin Cities including the Heilicher Minneapolis Jewish Day School.
