SANTA BARBARA, Calif. (AP) -- Wireless speaker maker Sonos Inc. says that its revenue in 2013 nearly doubled to $535 million in 2013.
The maker of the Play:1 speaker and other home audio devices said Monday that it decided to make the information public to give some context around the size of its business and its growth.
The privately held company, based in Santa Barbara, Calif., has investors that include Kohlberg Kravis Roberts & Co., Elevation Partners and Index Ventures, according to financial database S&P Capital IQ.
It was founded in 2002 and has filed for some 200 patents covering its system, which allows users to wirelessly stream music from dozens of online services including Pandora, Spotify and iTunes. Speakers operate over one's home Wi-Fi network and require only being plugged into a power outlet.
