Founded in 2004, GREE is the fastest growing tech company in Japan, according to Deloitte, as well as Japan’s leading mobile social gaming platform, with 26 million unique users, over a billion daily page-views and $168 million in revenues in the second quarter of this year alone. It’s listed on the Tokyo Stock Exchange and was founded by Asia’s youngest self-made billionaire, Yoshikazu Tanaka. Now this digital leader is expanding globally, acquiring OpenFeint, the largest mobile social gaming network, in April and now launching in the US with D/C as its marketing agency. Based in San Francisco, the mission of GREE International is to bring mobile social gaming to the next level, literally and figuratively. And D/C is literally, figuratively and totally psyched to help.
