What it is

Coldrange is a multi-domain digital twin: an interactive battlespace built from measured terrain, platforms and weather. Drone systems, autonomy and the software that plans and commands them are developed and proven inside it, on land, at sea and in the air, among civilians and the infrastructure they depend on, against an adversary that fights back and adapts.

Today’s threats are already on the battlefield. Tomorrow’s are coming faster than defenses can be proven.

AI now writes the code, drafts the design and iterates in hours, on both sides of the front. A defense built for one generation of drones meets the next before it is proven.

Proving still takes real hardware and a real place. Designated flight areas exist, and getting into one takes an authorization, not a booking. A range gives you airspace. It does not give you an adversary.

NATO’s own simulation group reports that making simulation systems interoperable and their results credible “currently requires large efforts with regards to time, personnel and budget.”

A real port from the air, photoreal terrain, with authored waypoints and their speeds marked over the water.

Develop where you prove.

Pick a real place. Plug in what you are developing, from your own bench: a flight controller, a sensor, a whole system. It goes up against an adversary that fights back. Change it, and run it again, until it holds.

A flight controller on a bench believes it is airborne, flying a mission, being hunted.

Digital twin, then software in the loop, then hardware in the loop, then the real device. Each step cuts the errors that reach the next, so test day is for confirming, not discovering.

AI-native

AI on both sides.

One environment

Your side

AI agents build your scenarios, connect your hardware and extend Coldrange to fit what you need. People stay in the loop as the decision makers. An agent proposes, a named person decides.

The other side

The adversary is AI, or your own people as a red team. It plays the next threat, not the current one, and adapts to every change you make. With people on that side, you prove the system and train the organization that runs it.

The world

Built in layers, like the real one: organizations and their chains of command, devices, communications, civilians.

Who it is for

Builders and defenders. One environment.

Builders

Drone and component makers

Drone and counter-drone systems, aerial to underwater, and the flight controllers, sensors and radios inside them. Run them against a live opponent before you have a permit or a range, and see what your system does when things go wrong.

Autonomy and AI teams

Train and validate decision-making and multi-vehicle coordination in a real place, against a hostile force, for as many hours as it takes.

Command, control and mission planning

Run your software over a whole unit in a contested scenario, and see where coordination breaks under pressure.

Defenders

Defenders of a harbor, a site, a force

Where the sensors go, what holds, what breaks, and what changes when the threat does.

Builders prove their systems against tomorrow’s threat. Defenders prove their setups against tomorrow’s attack. Same environment, same interfaces.

Sovereign

Built for European defense.

European models, or your own, in our environment or a dedicated one, and offline on your own premises where that is required. Your code and data stay in Europe.

The tactical map: friendly and hostile units on real terrain, with the order of battle listed beside it.
Open

Open, so others can build in it.

Open interfaces and published protocols. Your hardware and autonomy run inside the environment on your terms, not a vendor’s.

It has happened before, one layer down. Much of the drone supplier tier builds on open autopilots like ArduPilot and PX4.

Bring your own system

Every integration we absorb makes the next one cheaper.

Share how your system is built, its manuals and its protocols, and we map it into the environment.

Build with us

Meet tomorrow’s threats before they arrive.

Build with us. We are building Coldrange in the open, with partners. If you build drones, autonomy, command software or the components inside them, or defend what they threaten, tell us what you need to prove.

hello@coldrange.ai

Coldrange is new. The experience is not. The team has more than a decade of building hardware-in-the-loop systems, software that talks to real hardware from drones to tanks, including projects for NATO and the British military. It also brings decades of international business experience, and a track record of successfully building and scaling ecosystem products.
