Founded in 2014 by an experienced team of industry veterans, Disbelief has offices in Cambridge, MA and Chicago, IL. We’ve since helped multiple titles ship on Console, PC, VR, and Mac.

We care deeply about quality. We strive to be responsive to client needs and anticipate future problems. We approach problems with a steady hand and try to reduce the chaos of game development, not increase it. We value ingenious solutions to our clients’ problems and work beyond the limitations of off the shelf technology.

Our founding team has had a lifelong passion for working on video game technology. Before we formed Disbelief, our core team was the Core Technology Team for BioShock Infinite at Irrational Games. Earlier than our stint at Irrational games, we were the core of the programming team for John Woo Presents Stranglehold at Midway Games. Members of our team have also worked on Injustice 2, Mortal Kombat X, Psi-Ops: The Mindgate Conspiracy, Disney's Guilty Party, World Of Tanks and more.
