Grant Cardone interviews Marshall Terrin, owner of True Stim, to talk about how Marshall went from broke to a $10 Million Dollar Business. Marshall is an Iraqi war veteran who at one point was just struggling to survive after transitioning back to civilian life. He was selling a neurological muscle stimulator over Amazon and making just $2,000 a month when he realized he could make a superior version of the product.

After connecting with the supplier in China, Marshall created a better over the counter neurological muscle stimulator, which relieves pain without drugs and increase muscle performance. He’s thrived as an underdog utilizing mall kiosks and using Cardone University.
