Improbable is a British technology company that focuses on large-scale simulations in the cloud, enabling virtual worlds of unprecedented scale and complexity. It can be used to create a large and seamless world containing many players and objects by allowing for parallelization among a large number of machines. Developers can create a simulation that runs on 1 machine then easily scale it with Improbable's technology to numerous machines to create the massive simulated world.
Improbable's first product for reality-scale simulations is SpatialOS; a distributed operating system capable of producing consequential, persistent simulations at unprecedented scale. SpatialOS is being deployed in many progressive game studios and the most critical government institutions across the world.
