Secret Millionaires Club The series follows adventures in business with Radley, Elena, Jones, Lisa, their robot Starty, and Warren Buffett as their wise mentor. Every episode focuses on different business situations that kids might encounter in their own lives like having to raise money for something they want, or helping a local merchant understand why their business isn't working.
