LivingSocial, a social discovery and cataloging network poised for exponential growth with 6.4 million beta users, has closed more than $5 million in Series A funding. The round was led by Grotech Ventures and includes a personal investment from Steve and Jean Case.

“The support of Grotech Ventures and Steve and Jean Case will help establish LivingSocial as the leading social discovery and cataloging network, a centralized, user-managed community where people can organize, review and share what they are most passionate about,” says Tim O’Shaughnessy, CEO and co-founder of LivingSocial. “Based on sheer number of reviews we already have on our site, there is no other interest-based community with the volume of user-generated cataloging, and we’re just getting started.”

In coming months, LivingSocial plans to introduce additional product enhancements and new interest categories, further building its network to leverage users’ real world interests. The company’s innovative management team, which includes technical visionaries and former product managers from AOL, Revolution Health, and Blockbuster Online, has identified an exciting product roadmap that will further enhance user experience.

LivingSocial lets users manage and catalogue their interests and share reviews with peers across its themed vertical websites ReelSocial, ReadingSocial, TuneSocial, GamingSocial, DiningSocial and BrewSocial. Once posted on LivingSocial.com, users’ catalogued items and reviews are seamlessly integrated and easily accessed across top social networks, including Facebook, MySpace, Bebo, Orkut and hi5. With their first round of funding, the company is poised for aggressive user acquisition – continuing momentum from the significant growth achieved since its beta launch.
