Nate and his brother earned $300,000 in passive income by licensing one of their ideas to Mattel. They didn't have to design it, produce it, or sell it. But they found someone who could, and they cashed the checks. And to be fair, Nate will be the first to tell you these kind of results aren't typical -- but he's proof they ARE possible. Nate's actually a dentist by day, but a pretty serious side hustler by night, and on this call we take a deep dive into the world of product licensing.
