ARX Robotics is building Europe’s leading autonomous ground vehicles (UGVs) – the Gereon RCS series – and Mithra OS, an AI-driven operating system that integrates autonomous and legacy assets
ARX Robotics successfully completed its €31 million Series A funding round, led by HV Capital with participation from Omnes Capital and significant support from existing investors NATO Innovation Fund and Project A. With this new funding, ARX is set to strengthen its leadership in modular, AI-powered ground robotics.
Europe’s shifting geopolitical landscape is driving a renewed focus on defence modernization and strategic autonomy. As European nations bolster their capabilities, demand for advanced, AI-driven autonomous systems is rising. Land operations remain vastly under-automated – despite accounting for 80% of all military activities, 70% of material usage, and 40% of total procurement. ARX Robotics is bridging this gap by digitising and autonomizing European forces – equipping them with advanced capabilities through high-performance UGVs, modernised legacy systems, and seamless AI-driven connectivity across land, air, and sea domains.
Founded by Marc Wietfeld (Co-Founder and CEO), Maximilian Wied (Co-Founder and CFO), and Stefan Roebel (Co-Founder and COO), all former officers in the German Bundeswehr, the Munich-based company seeks to strengthen European resilience. Its unique offering in mobile robotics, including the world’s first independent AI-powered operating system for legacy vehicles, ARX Mithra OS, helps militaries increase their operational efficiency and enhance situational awareness as they modernize their fleets.
“The demand for modular, software-driven defence systems is growing rapidly—and we’re building the company that will define this category in Europe„, said Marc Wietfeld, co-founder and CEO of ARX Robotics “At the core of ARX Robotics is a clear mission: to build the next generation of defence infrastructure through scalable robotics and software. We’re happy to be partnering with such renowned investors who back this mission. This fresh funding is an important milestone and catalyst that allows us to move from successful deployments to industrial scale.”
Since its founding in 2022, ARX Robotics has become the leading UGV supplier to key European markets, including Germany, Ukraine and the UK, with six European military forces currently deploying them.
ARX also supplied the Ukrainian Military with the largest Western-developed fleet of UGVs and was recently contracted by the European Defence Agency (EDA) to participate in the first EU-wide defence innovation initiative. With its technology, ARX Robotics has the potential to retrofit over 50,000 NATO vehicles. With a fully European supply chain, ARX ensures that mission-critical technology stays under European control, aligned with the continent’s sovereignty and resilience goals.
Fabian Gruner, Partner at HV Capital, said: “ARX is proof that Europe can build internationally relevant defence technology: modern, AI-native, and strategically sovereign. Their rapid deployment across Europe is a testament to both the urgency and strength of their product. HV Capital is thrilled to back this exceptional team and their mission.”
Chris O’Connor, Partner at NATO Innovation Fund said, “We are proud of the tremendous progress the ARX Robotics team has made over the previous year, including growing their suite of products to address the legacy ground fleet, expanding geographic reach and building a world class team. ARX Robotics has fielded the largest Western UGV fleet to Ukraine and we look forward to continuing to support the company as it expands its reach across NATO nations.”
With the Series A funding round ARX Robotics is entering the next phase of growth and plans to significantly scale production, accelerate its European expansion into key markets, and strengthen its AI-driven defence capabilities. The company plans to continue investing in top-tier European AI talent and further enhancing ARX Mithra OS as the backbone of autonomous defence.
