Ring, a US-based smart doorbell developer backed by insurance provider American Family Insurance and home builder JF Shea, has raised $61.2m in a series C round featuring Kleiner Perkins Caufield & Byers.
Richard Branson, founder of conglomerate Virgin, also contributed funds to the round.
Ring produces a video doorbell that lets users see and talk to visitors through their smartphone without having to open the door, or when they are not actually home. The technology also includes motion sensors to detect potential burglars and alert the homeowners.
The funding will be used by Ring to expand its product offering and boost its international expansion efforts.
Ring attracted $28m in an August 2015 series B round co-led by American Family Insurance, JF Shea’s Shea Ventures investment subsidiary and Richard Branson. True Ventures, Upfront Ventures and a range of angel investors also took part in the round.
True Ventures previously led a $4.5m series A round in 2014, with participation from Upfront, First Round Capital, Queensbridge Venture Partners and angel investors. Ring had already secured $2.5m in debt financing at the time.
First Round, Upfront, Charles River Ventures and angel investor Matt Mullenweg, the founder of blogging platform WordPress, injected $1m in seed capital in December 2013, following the company’s successful $250,000 crowdfunding campaign in January 2013.
