Loopt is a company based in Mountain View, California, United States. Loopt produces mobile location-based services that allow users to discover the world around them, and find and enjoy the friends, places and events around them via smartphones.
Loopt supports the phones iPhone, BlackBerry, Android and Windows Phone. The Loopt services have more than five million registered users and partnerships with every major U.S. mobile phone carrier. Loopt applications offer a variety of privacy controls. In addition to the core features of Loopt, users also have the ability to integrate Loopt with other social networks, including Facebook and Twitter.
The company was founded in 2005 and received initial funding from Y Combinator. Loopt has completed Series A and B financing led by Sequoia Capital and New Enterprise Associates. Loopt board members include TiVo-founder Mike Ramsay and Greg McAdoo of Sequoia Capital.
Loopt began with seed funding from Y Combinator, a venture firm specializing in early stage startups. 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, Sam 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.
In February 2009, Loopt expanded service again to select AT&T phones, making it the first service since SMS available across all major networks.
In March 2010, Loopt launched an upgraded version of its iPhone app, incorporating place and event information to its Pulse database, bringing in content from ZVents, Metromix, and SonicLiving. These are added to existing content partnerships with Citysearch, Zagat, and Bing.
In March 2010, Loopt launched a product called Loopt Pulse, exclusively designed for the iPad.
In December 2010, Loopt launched Loopt version 4.0, which featured a completely updated design.

- Loopt Star — This mobile game rewards people for often checking into certain places. In late 2010, all related functions were moved into the core Loopt app for iPhone and Android. Accordingly, Loopt Star was removed from the iOS App Store and Android Market.
Loopt is permission-based and users share location information only with their selected friends, networks, and services. Loopt users can turn location-sharing on or off at any time on a friend-by-friend basis or for all friends at once.
Loopt works regularly with select organizations that focus on privacy and security including: The Family Online Safety Institute (board member); ConnectSafely.org; Ponemon Institute; Electronic Frontier Foundation; National Network to End Domestic Violence; Progress & Freedom Foundation's Center for Digital Media Freedom; Internet Education Foundation; and Cyber Safe California by the California Office of Privacy Protection (member, advisory committee). Loopt sits on the CTIA's WIC Leadership Council and was an active participant in the creation of the CTIA LBS Best Practices.

SMS invitation issues 
When Loopt released its native iPhone application on July 10, 2008, the software quickly gained notoriety for sending Short Message Service (SMS) invites to users' address books without, it seemed, the user's knowledge. More upsetting, the SMS service failed to respond to the industry required STOP message. Merlin Mann complained, "I'm getting SMSs from Loopt users asking me to be their friend or whatever. I never asked for this. SMSs cost money."
On July 14, 2008, Loopt posted to its blog that the mass invites could be attributed to a confusing user interface, and they are working on an improved invitation flow. The comments, however, point out they continue to ignore STOP messages (a command that automated text-message services use which is supposed to allow people to control whether they receive messages). Respect for STOP was announced July 15, 2008, and on July 17, 2008, Loopt released an updated version which addressed the issues with the confusing user interface.
