Jamie Siminoff Net Worth

Jamie Siminoff net worth in 2026 is estimated at $300 million. The estimate is based on his reported 25 to 30 percent stake in Ring and the reported price of more than $1 billion that Amazon paid for the company in 2018. Other outlets have published figures up to $350 million, which reflects uncertainty about the exact deal price and his stake.

Amazon acquired Ring in 2018 in a deal reported at more than $1 billion, with some reports putting the price between $1.2 billion and $1.8 billion. Amazon never officially confirmed the price. The most commonly cited figure is around $1 billion, which is the number most outlets use when estimating Siminoff's fortune.

Siminoff pitched DoorBot on Shark Tank in 2013 and asked for $700,000 for 10 percent of the company. The sharks passed on the equity deal, and Kevin O'Leary offered a loan with a royalty instead. Siminoff declined the loan offer and left without a deal. He later renamed the company Ring and built it into a billion-dollar acquisition.

Siminoff returned to Amazon in April 2025 as a vice president overseeing Ring, Blink, Amazon Key and Sidewalk. Before that he spent two years as chief executive of Latch, a smart lock company, after leaving Amazon in May 2023. He also published a book about his journey, Ding Dong, in November 2025.

Ring started as DoorBot in 2011, when Siminoff built a video doorbell in his garage because he could not hear his doorbell from his backyard. The device let homeowners see and talk to visitors from a phone. He launched it through crowdfunding, renamed it Ring in 2014, and grew it into the leading video doorbell brand before Amazon bought it.

Jamie Siminoff was born on October 18, 1976, which makes him 49 years old for most of 2026 and 50 in October. He graduated from Babson College in 1999 and founded Ring at age 34. His Shark Tank appearance came in 2013, when he was 36 years old. He returned to Amazon as a vice president in April 2025, after two years leading Latch.
