Sumo Digital

Sumo Digital was founded in 2003 by Carl Cavers, Paul Porter, Darren Mills and James North-Hearn, four members of the former management team of Infogrames Studios, after that company had been closed down. In 2007, Sumo Digital opened a subsidiary studio in India, called Sumo India. In August 2007, Foundation 9 Entertainment announced that it was acquiring Sumo Digital, wherein North-Hearn became the manager of Foundation 9's European operations.
