The team-building specialist ran 32 espionage-themed events in the first quarter of 2010 compared to 14 in the first quarter of 2009.
Spy Games' activities include hostage rescues, diamond heists and surveillance operations, tailored to meet business objectives ranging from communication and leadership to health and safety.
Events took place at UK locations including the company's headquarters, near Milton Keynes, and other overseas locations.
Spy Games managing director David Thomas said: "Last year, a lot of companies simply were not spending money on these types of activities, but this year we have seen a massive increase in sales. I think there's a recognition that now is the time to train and reward staff, and businesses clearly want to do that in a way that's exciting and fresh."
