Tile is an American consumer electronics company which produces devices to help users find their belongings, such as keys and backpacks, which use Bluetooth 4.0. The devices work with a companion mobile app for Android and iOS, which allows users to locate lost items through Bluetooth or where they were last seen. In September 2018 GoPro vet CJ Prober became CEO of Tile. In September 2015, Tile launched Generation 2 hardware that includes find-your-phone functionality and other feature upgrades, which by January 2016 sold over 4.5 million units. In August 2017, two new versions of the Tile were launched, the Tile Sport and Tile Style. As of 2019, the lineup consists of the Pro, Mate, Slim, and Sticker.
