Coldrange is a Finland-based company developing an open, multi-domain simulation environment for drone systems, hardware and autonomy. Its interactive virtual battlespace uses digital twins of real terrain, platforms and weather, allowing systems to operate across land, sea and air and face simulated hostile conditions such as electronic warfare, jamming and GPS denial. The platform helps teams prove how their technology performs before gaining access to real-world flight areas or ranges.

Coldrange serves drone and counter-drone manufacturers, component makers, autonomy and AI teams, and developers of command, control and mission-planning software. Users can run real hardware, including flight controllers, alongside their software in the simulated environment, then make changes and repeat tests rapidly. The company emphasizes open interfaces and published protocols, enabling customers to integrate their systems on their own terms. Coldrange is being built with early-access partners. Its team brings more than a decade of experience in hardware-in-the-loop systems, including projects for NATO and the British military, as well as experience building and scaling ecosystem products.
