Few startup stories are as compelling as that of Jamie Siminoff, the founder of Ring. Once a struggling entrepreneur pitching his idea on Shark Tank—and walking away without a deal—Siminoff turned that rejection into fuel. His doorbell-camera company, which began in a garage, grew into one of the most recognizable smart-home brands in the world. Eventually, Amazon acquired Ring in a deal worth more than $1 billion, turning Siminoff into a multi-millionaire almost overnight.

But how much is Jamie Siminoff really worth today? Let’s break down his net worth, income sources, and even how his fortune translates into gold bars—while also exploring his future beyond Ring.

• Defining Moment: Appeared on Shark Tank in 2013 with his startup DoorBot (later renamed Ring).

This underdog story became legendary: the entrepreneur rejected by TV investors later sold his company to Amazon for a 10-figure deal.

This deal instantly made Siminoff one of the richest entrepreneurs in the smart-home sector. He joined Amazon as Chief Inventor for Ring, continuing to guide innovation until 2020.
