Defense of the future: Arx Robotics relies on AI and autonomy
The Munich Defense-Tech Startup Arx Robotics has successfully completed a Series A financing round of 31 million euros. With this significant investment, the company strengthens its position as a leading European developer of autonomous soil robots and AI-based defense systems. Funding underlines the growing interest in innovative defense technologies and the increasing importance of European defense sovereignty in a changing geopolitical environment.

Successful financing round and participating investors
The financing round announced on April 28, 2025 was led by HV Capital, with the participation of Omnes Capital as well as the inventory investor NATO Innovation Fund and Project A. This compilation from established venture capital and strategic partners such as the NATO Innovation Fund illustrates trust in the technology and the business model of ARX Robotics.
"Arx shows that Europe can develop international competitive defense technology-modern, AI-based and confidently," explains Fabian Gruner, partner at HV Capital. For the NATO Innovation Fund, it is already a follow-up investment after it led a seed financing round of 9 million euros in June 2024. Project A had been involved in ARX since September 2023 when the investor headed a pre-seed round of over 1.15 million euros for the then young company.
The current financing round is in the context of an increased interest in defense technologies, especially after the beginning of the Ukraine secretary, which has significantly increased the demand for military innovations.
Founding history and management team
Arx Robotics was founded in 2022 by three former Bundeswehr officers: Marc Wietfeld (CEO), Stefan Roebel (COO) and Maximilian Wied (CFO). The company was created as a spin-off of the Gereon research project at the University of the Bundeswehr Munich. These military expertise of the founders forms a solid basis for the development of practical solutions for modern defense requirements.
"The demand for modular, software -defined defense systems increases rapidly - and we are building the company that will shape this category in Europe," emphasizes Marc Wietfeld, CEO of Arx Robotics. The management team follows a clear vision: "We are pursuing a clear mission: the development of the next generation of defense technology infrastructure through scalable robotics and software".
Technology portfolio and product range
Arx Robotics specializes in two main areas: the development of autonomous unmanned floor vehicles (UGVS) of the Gereon-RCS series and the AI-based operating system Mithra OS.
Unmanned the Gereon series floor vehicles
The Gereon family of unmanned floor vehicles forms the heart of the Arx Robotics product range. These modular robot systems can be equipped for various military scenarios, including:
- Shooting exercises and simulations as movable goals
- Transport of material and equipment
- Medical evacuation (Casevac)
- Special sensor applications for reconnaissance missions
The floor vehicles come in four different sizes, whereby the largest version can transport up to 500 kg of payload. At a speed of up to 30 km/h and a range of 40 km per battery charge, the Gereon systems are designed to keep up with infantry units even in difficult terrain.
Arx Mithra OS - Autonomy software for existing vehicles
In addition to the hardware, Arx Robotics with Mithra OS develops the world's first independent AI-based operating system that can convert existing military vehicles into intelligent, networked autonomous units. This system enables:
- The digital networking of existing vehicles
- Optional unmanned and autonomous operation
- Support of human-machine teams (Manned-Unmanned Teaming)
- Machine learning for continuous mission optimization
"Arx Mithra OS enables armed forces to operate efficiently and transform existing vehicle fleets into digitally networked intelligent units," the company describes the software. With this technology, Arx is able to modernize over 50,000 NATO vehicles.
Strategic partnerships and market position
Arx Robotics has already made important strategic partnerships that strengthen its market position and open up growth opportunities.
Cooperation with Daimler Truck
At the end of March 2025, Arx Robotics and Daimler Truck signed a declaration of intent for a strategic partnership to improve digital skills in military vehicles. The cooperation focuses on the integration of robotics and artificial intelligence into the Mercedes-Benz special vehicles, including the Unimog and Zetros models.
As part of this partnership, the ARX Mithra OS is integrated into Daimler's defense platforms in order to enable networked, remote -controlled and autonomous operations. The aim is to improve efficiency and surgical effectiveness, especially for missions in several domains.
International presence and missions
Arx Robotics systems are already used by six European armed forces, including Germany, Ukraine and the United Kingdom. Particularly noteworthy is:
- The provision of the largest western UGV fleet for the Ukrainian army
- The use of Gereon-RCS systems in the Bundeswehr in Slovakia to strengthen the NATO-East flank
- The commissioned by the European Defense Agency (EDA) for the first EU-wide defense innovation initiative
In February 2025, Arx Robotics opened Europe's largest production facility for military robot systems in the Munich metropolitan region, which is an important milestone in corporate development.

Expansion plans and use of fresh capital
With the newly recruited 31 million euros, Arx Robotics is pursuing ambitious growth plans in several areas.
Expansion of production capacities
The company plans to steady its production capacities for autonomous mobile robots in 2025. This should serve the increasing demand for the systems and enable industrial production on a large scale. In the past six months, Arx has increased its production capacity for unmanned systems by thirty times.
International expansion
Arx Robotics is driving its expansion to other European countries. The recently announced market entry in Great Britain is particularly important:
- Opening of an office in London
- Building a new production facility in the south of England
- Investment of £ 45 million (approx. 53 million euros) in the British presence
- Creation of 90 jobs in the next two and a half years
In the UK, the ARX robots are already subjected to strict field trials and adapted to the British use requirements. "In close coordination with the 1st Queen's Dragoon Guards (QDG), we are now actively investigating the integration of our Gereon RCS into the British warfare doctrines," said the company.
Further development of technology
Another focus is on the further development of the AI-based operating system ARX Mithra OS. The company wants to continue to invest in European AI talents and establish its software as a backbone of autonomous defense systems. The acceleration of the development and introduction of this autonomy software is intended to enable AI-based modernization of NATO portfolio fleets.
Meaning for European defense sovereignty
Arx Robotics deliberately positions itself as the key player for strengthening European defense sovereignty. At a time when European countries are increasingly investing in their defense skills, the company offers modern, autonomous technologies with a completely European supply chain.
There is a high automation requirement, especially in the area of land operations that make up 80% of all military activities. With its modular robot systems and AI-based control systems, ARX aims to make the armed forces more efficient and resistant.
"European armed forces have a structural disadvantage in relation to personnel and equipment compared to potential opponents. Unmanned systems have the potential to bridge this capacity gap - provided they can be produced on a large scale," explained Marc Wietfeld when the new production facility was opened.
Artificial intelligence and robotics: How Arx Robotics shapes the future of warfare
The successful round of financing from Arx Robotics marks an important milestone for the company and reflects the growing importance of autonomous systems in the defense area. With 31 million euros in fresh capital, Arx Robotics is well positioned to expand its production capacities, expand internationally and further expand its technology leadership in the field of autonomous soil systems.
The integration of artificial intelligence and robotics into military applications is increasingly being viewed as a decisive factor for the future of warfare. Arx Robotics is at the top of this development in Europe and helps to strengthen the technological sovereignty of the continent.
With its clear focus on modular, software -controlled defense systems and a strong investor base, Arx Robotics is well positioned in order to operate the growing demand for autonomous systems and to play a leading role in the European defense industry. The coming years will show to what extent the company can reach its ambitious growth goals and realize its vision of a stronger European defense sovereignty.
