Japan's Gumi hires former Xbox game exec to storm North American mobile game market

Japan’s Gumi is flush with cash thanks to Brave Frontier, a huge mobile gaming hit in Japan. Now the company is expanding into the U.S. market, and it has hired AJ Redmer, a former studio manager at Microsoft’s Xbox division and one of the creators of the Xbox 360 game console, to help with its Stateside push.

Gumi is opening four sizable game studios, including one in Austin, Texas, and it plans to invest even more by the end of the year. It shows how competition has moved to a global stage in the mobile gaming (an estimated $20 billion market in 2014), and the companies that have figured out how to make money in mobile are investing in bigger guns.
