Belerion

The AI Defence Company
Empowering Operators

Better real-world decisions under uncertainty.

A Belgian startup building AI control software for defence and civil autonomous systems.

Our products target situations where conditions are unpredictable and decisions need to be fast: counter-drone operations, unmanned platforms, and robotic systems. Built on reinforcement learning, our software learns to make good decisions under uncertainty and integrates directly into existing platforms.

Research-Driven

Built on years of academic research and collaboration with European defence actors.

Product-Driven

Scalable software products, deployable as licences, designed to integrate into your existing systems.

European

Based in Belgium. Built for European operational and sovereignty requirements.

How We Work

Explore

Identify the right use case and define the problem jointly with the client.

Simulate

Build high-fidelity simulation environments to train and validate safely.

Train

Develop AI agents that learn to decide well under real-world constraints.

Integrate

Deploy as a software component that enhances existing systems, not replaces them.

Services

Beyond our products, we offer specialist engineering services for both defence and civil sectors.

Machine Learning Engineering

Computer vision pipelines, large language model fine-tuning, and predictive analytics tailored to your operational data.

Simulation Development

Design and refinement of high-fidelity simulation environments for training, testing, and validating autonomous systems.

Bespoke R&D

End-to-end applied research following our product pipeline — from problem scoping through simulation to deployed AI agents.

Core Team

Founded by AI researchers and engineers shaping the future of defence technology.
