What is Jamie Siminoff's net worth?
According to Celebrity Net Worth and Foresight Journal, Jamie Siminoff's alleged net worth is $300 million as of 2025. He has amassed wealth by selling his Ring doorbell invention to Amazon and proceeds from start-ups such as Unsubscribe.com, PhoneTag, and Gadgetronics.

Jamie later launched several other start-ups, including PhoneTag, a voicemail-to-text transcription service. He sold this business in 2001 for $1 million.
He also sold his second start-up, Unsubscribe.com, which helped users manage unwanted emails, for $17 million in 2009. Both ventures demonstrated his ability to identify and solve daily problems using innovative solutions.
In 2011, Jamie Siminoff created Ring, formerly Doorbot, while working in his car garage. This invention is a Wi-Fi-enabled video doorbell that streams live video of a home's front doorstep to a smartphone. It also included a burglary deterrence feature that allowed users to pretend to be in the house while they weren't.
The Doorbot aimed to enhance both home security and convenience. The American entrepreneur first raised money for his invention through crowdfunding.
Jamie Siminoff's Shark Tank investment
Siminoff pitched Doorbot on ABC's hit show Shark Tank in 2013, seeking an investment to take his product to the next level. When he appeared on the show, he was already making around $1 million in annual sales.

The inventor urged the sharks to invest $700,000 for a 10% stake in his company. That is a $7 million valuation. He got four rejections and one offer from Kevin O'Leary. However, Jamie rejected this offer as it was a complicated loan/royalty deal.
Despite leaving without securing a deal, the appearance garnered global attention, resulting in approximately $5 million in additional sales. Recognising the need for a stronger brand identity, Doorbot rebranded to Ring in 2014, aligning more closely with its mission to offer comprehensive home security solutions.
Ring's innovative approach drew significant investment, including over $200 million from renowned entities such as Goldman Sachs, Qualcomm Ventures, Kleiner Perkins, Sir Richard Branson, and DFJ Growth.
These investments enabled Ring to expand its product portfolio and market reach, solidifying its position in the smart home security industry.
