X-Mode Social is a US company founded in 2013 and specialized in location data and based in Reston, Virginia.
Joshua Anton, a student at the University of Virginia, created a mobile application named Drunk Mode to prevent users from dialling phone numbers or texting while inebriated. The application was free and has more than one million downloads. He came up with the idea of collecting data from the application's users and reselling it to advertisers and founded X-Mode in 2013.
The company is based in Reston, a city that is part of the Dulles Technology Corridor, a cluster of companies hosting many firms active in defence and technology. The company offers a software development kit, a library that facilitates the functionality of the applications, which once installed in code allows access to the location data of the owners of these phones once the application is installed. In total, X-Mode works with more than 70 developers on more than 300 applications such as games, travel guides, dating sites, ... In total more than 50 million active people per month are sharing their location every 5 to 7 minutes. Location data are obtained from GPS data, data from Bluetooth signals emitted by the phone and picked up via detection beacons and data from Wi-Fi routers especially inside buildings and available through the permission settings and permissions granted to downloaded applications.
