Sonos is an American developer and manufacturer of audio products best known for its multi-room audio products. The company was founded in 2002 by John MacFarlane, Craig Shelburne, Tom Cullen, and Trung Mai. It is currently run by Patrick Spence. Sonos has partnered with over 100 companies that offer music services, including Pandora, iHeartRadio, Spotify, MOG, QQ Music, and Amazon Music. Sonos products work with the three major voice assistants: Amazon Alexa, Google Assistant, and Apple Siri, although the latter is currently only supported through Apple's Home app. In 2019 Sonos acquired Snips SAS, a privacy-focused AI voice platform for connected devices with the goal to bring a music-specific assistant to its devices.
