Loopt

Loopt, founded in 2005 by Stanford students Sam Altman, Nick Sivo, and Alok Deshpande, emerged as an early entrant in the location-based social networking space. The company's genesis traces back to a class taught by renowned venture capitalist Paul Graham, who encouraged the founders to drop out of Stanford and provided their initial seed funding through his accelerator, Y Combinator, making Loopt one of the first eight companies to participate in the now-famous program. Sam Altman, who served as CEO, along with his co-founders, capitalized on the burgeoning capabilities of GPS-enabled mobile phones to create a service that connected users with their real-world surroundings.

The company's primary offering was a mobile application that allowed users to see their friends' locations on a map, discover nearby points of interest, and receive alerts when friends were close. This social-mapping service operated in the consumer mobile application market, targeting a young, tech-savvy demographic keen on sharing their activities and whereabouts. Loopt's business model was multifaceted; it initially partnered with mobile carriers like Sprint, Boost Mobile, and AT&T to be pre-installed on devices, generating revenue through subscription fees or as part of a data package. As the mobile landscape shifted with the advent of app stores, Loopt adapted by offering its application directly to consumers and exploring revenue streams through location-based advertising and deals with local businesses.

Throughout its operation, Loopt secured significant financial backing, raising over $39 million from prominent venture capital firms, including Sequoia Capital and New Enterprise Associates (NEA), which underscored investor confidence in the potential of location-based services. The service was notable for its interoperability, functioning across various mobile operating systems and carriers at a time when the mobile ecosystem was highly fragmented. After navigating the competitive and rapidly evolving social mobile landscape for several years, Loopt was acquired by Green Dot Corporation, a prepaid debit card company, in 2012 for $43.4 million. The acquisition was primarily aimed at leveraging Loopt's talent and mobile technology expertise to build out Green Dot's own mobile financial services platform.
