Tokyo-based VC firm Global Brain announced today it has invested in South Korea’s Mbite, the Seoul-based startup behind illustration task crowdsourcing platform Rainbow.dot. Details of the investment have not been disclosed. Rainbow.dot allows game developers to improve the efficiency of their production systems by crowdsourcing their illustration tasks to more than 300 remote workers in Korea. To help foreign game developers order their work from Korean crowdsourced workers using the platform, the company has installed a multilingual translation system to eliminate language barriers. Since it launch in 2011, the company has been providing a content distribution platform for amateur cartoonists in Korea called Indiket. They subsequently launched a new platform called Inkoo last year to give Korean cartoonists more opportunities to work with Japanese companies. Mbite will use the funds raised to expand their business in the Chinese and English-speaking markets. For Global Brain, this is their third investment in Korean startups following 5Rocks and VCNC. In this space, we’ve seen several Japanese startups like Mugenup doing a similar business.
