Shark Tank Biography
A lifelong inventor and successful entrepreneur, Jamie Siminoff created the world's first Wi-Fi video doorbell while working in his garage in 2011. He pitched his doorbell, then called DoorBot as a Shark Tank entrepreneur in 2013, turned down the only offer he received from Shark Kevin O'Leary and left without a deal. He has since transformed his invention into what's now known as Ring, a security powerhouse that offers several DIY home security products and services, including the popular Ring Video Doorbell that's capable of preventing and solving neighborhood crime. Under his direction, Ring has seen incredible success and growth.
In 2018, Amazon purchased Ring, the company's second-largest acquisition. With the support of Amazon, Ring and Siminoff continue to innovate and remain at the bleeding edge of home security. Prior to Ring, Siminoff founded several successful ventures including PhoneTag, the world's first voicemail-to-text company, and Unsubscribe.com, a service that helped email users clean commercial email from their inboxes. He successfully sold both companies in 2009 and 2011, respectively.
