Moshe Weiss, a school teacher turned inventor who became famous after appearing as a contestant on a reality business TV show, passed away on Monday, 25 Av, 5776.

He was 41 and passed away in his hometown of S. Paul, Minnesota.

A Yeshiva student in his youth, he studied at Yeshiva Ohr Elchonon Chabad in Los Angeles and at the Rabbinical College of Australia and New Zealand. He later enrolled at University of St. Thomas to study special education.

He taught at the now defunct Yeshiva High School of the Twin Cities located in Cottage Grove, Minnesota.

Weiss became known as a motivational speaker for aspiring frum businessman after winning an investment on Shark Tank for a speaker device he invented for the iPad called the Soundbender.

His personal charm and ingenuity won him a $54,000 investment in his company from fashion mogul Daymond John in March 2013. The simple magnetic, power-free amplifier improves sound quality and clarity on iPad tablets.

Sales have risen ever since, Weiss said a few months later. “Before Shark Tank sales were at $7,000. Post Shark Tank we’re nearing $250,000.” His company was called Simply Amazinc, LLC.

He is survived by his three children, his mother, Dr. Eileen Weissof Los Angeles, and siblings Rabbi Mordechai Weiss, Mrs. Esta Sitrin, Isaac Weiss, Shimmy Weiss, Rabbi Yosef Weiss, Avrumi Weiss, Yehoshua Weiss, Dovid Weiss, Rabbi Mendel Weiss, Leah Brown, Devorah Lunger, Shaina Knobloch, Yaakov Weiss, and Shmulie Weiss.
