Ring LLC is a manufacturer of home security and smart home devices owned by Amazon. It manufactures a titular line of smart doorbells, home security cameras, and alarm systems. It also operates Neighbors, a social network that allows users to discuss local safety and security issues, and share footage captured with Ring products. Via Neighbors, Ring may also provide footage and data to law enforcement agencies to assist in investigations. The company was first founded in the Fall of 2013 by Jamie Siminoff as the crowdfunded startup Doorbot; it was renamed Ring in the Fall of 2014, after which it began to receive equity investments. It was acquired by Amazon in 2018 for over 250,000 requested. Siminoff's team envisioned the product's concept as an "alarm system literally turned inside out" in comparison to other security systems, describing it as a "pre-crime" system. In 2013, Siminoff and Doorbot appeared on an episode of the reality series Shark Tank to seek a 7 million. Kevin O'Leary made an offer as a potential investor, but Siminoff declined it. Siminoff estimated that the appearance led to $5 million in additional sales. On September 26, 2014, the company was rebranded as Ring as it launched its second-generation hardware; Siminoff explained that the new name and updated hardware was more reflective of the company's positioning of the doorbell as a home security product. In 2016, Shaquille O'Neal acquired an equity stake in Ring, and subsequently became a spokesperson in the company's marketing.
