Jamie Siminoff


Jamie Siminoff is the founder of smart home and home security company Ring Inc., which was acquired by Amazon.com in February 2018 for an estimated value of between $1.2 and $1.8 billion, after failing to secure a deal with any of the "sharks" on Shark Tank in late 2013.

Life and career

Siminoff is a 1999 graduate of Babson College.
In 2011, Siminoff created Ring, a WiFi-enabled video doorbell, as a way to see his doorbell when he was in the garage. He appeared as an entrepreneur on Shark Tank in 2013, when Ring was known as DoorBot. While the Sharks liked the idea, all of them declined to invest. In 2018, Ring was acquired by Amazon and then Siminoff returned to Shark Tank as guest shark.
