Ring appeared on Shark Tank under its original name, Doorbot, in 2013.
Doorbot was founded by Jamie Siminoff as a connected video doorbell. The device allowed users to see and communicate with visitors at their front door through a smartphone, an idea that later became central to the smart-home security market.
Siminoff pitched Doorbot on Shark Tank in 2013. The appearance did not result in a completed deal, although the product and founder received national exposure. The company later changed its name to Ring and expanded its product line beyond the original doorbell.
Amazon acquired Ring in 2018. The Shark Tank appearance is frequently discussed because the company became highly valuable after leaving the show without an agreement. This question is separate from the company’s later acquisition year: Doorbot’s televised Shark Tank pitch occurred in 2013, while Amazon’s purchase came five years later.
