That summer, Stanford sophomores Sam Altman and Nick Sivo worked to build the first prototype of Loopt. They were later joined by Alok Deshpande as well as two of Sam’s childhood friends, Rick & Tom Pernikoff.〔 Loopt received US$5 million in Series A funding from Sequoia Capital and New Enterprise Associates and struck a deal to launch the service on Boost Mobile devices in September 2006. Boost Mobile featured Loopt in a series of commercials that are most known for the “Where you at?” tag line. In August 2007, Loopt expanded the service to select Sprint phones, and in June 2008, to Verizon. Loopt announced support for most GPS-enabled Blackberries on June 13, 2008. Loopt received US$8.25 million in Series B funding in July 2007. In February 2008, Loopt and CBS did a deal to deliver location based advertising. Seven months later, Loopt released an opt-in feature in Loopt's iPhone application called, Loopt Mix, which uses location-based services to enable iPhone users to find and meet new people nearby. At Apple's Worldwide Developers Conference in June 2008, Altman presented the Loopt application for the iPhone. Loopt for the iPhone became available to US customers of the Apple iTunes App Store on July 11, 2008. The application is not yet available in other countries.
