Machine Zone raised $266 million, anchored by a $250M Series D (July 16, 2014) and earlier Series A/B tranches. Founded in 2008, Machine Zone developed high-scale mobile titles such as Game of War: Fire Age, and built a proprietary real-time (RT) analytics and backend platform to support massive concurrent gameplay. Funding was invested in global user acquisition, live-ops infrastructure, and scalable server architecture enabling the company to run large multiplayer economies and real-time event systems at scale.
