Core offering

ESOX Group designs, manufactures, and integrates defence electrification systems comprising solid-state batteries (ESOX Battery), direct drive electric motors (Theron Motor), and intelligent software for uncrewed ground, aerial, and maritime defence platforms. The company sells these as standalone components or as fully integrated platforms such as the X1 Interceptor Drone and X2 UGV demonstrator to NATO member states, defence ministries, and defence contractors.

Product overview

ESOX Group offers an integrated defence electrification platform comprising three core technology areas: ESOX Battery (solid-state energy storage with 400 Wh/kg density), Theron Motor (direct drive electric propulsion in four power classes), and ESOX Integrated Platforms (uncrewed aerial, ground, and maritime systems). The company provides these as a unified power and propulsion system or as independently specifiable components. Supporting software includes ESOX Software (no-code vehicle logic builder with AI) and Digital Twin 2.0 simulation environment. Key platforms include X1 Interceptor Drone, X2 UGV, Heavy Lift Quad Drone, Tank Steer UGV, and Autonomous Surface/Underwater Vessels.

Features 240+ kph top speed, 360 km range, 30 kg modular payload, autonomous-ready I/O and compute, and AI-powered target acquisition. Sold to NATO and allied defence forces for counter-drone operations.
• X2 UGV Technology Demonstrator Compact autonomous ground vehicle platform showcasing integrated propulsion and control systems using four 12-inch Theron Motors in tank-steer configuration. Serves as testbed for solid-state battery deployment and integrated propulsion solutions for defence and security applications.
• Heavy Lift Quad Drone Heavy lift aerial platform built for contested logistics and resupply, powered by proprietary low-RPM high-torque motors. Features 100+ kg payload capacity, extended endurance via solid-state battery, low acoustic signature, and modular payload bay. Sold to defence forces for contested logistics missions.
• Tank Steer UGV In-wheel motor uncrewed ground vehicle engineered for all-terrain resupply and force protection. Delivers 120 kW peak power, 1200 Nm peak torque, 600 kg payload capacity, and 200+ km range. Sold to defence forces for logistics and force protection missions.
• Autonomous Submersible and Surface Vessels Uncrewed surface and subsurface vessels engineered for persistent maritime operations in contested environments. Features all-weather hull design, extreme temperature validation, minimal radar cross-section, and low acoustic signature. Sold to naval and maritime defence forces.
• ESOX Software Visual no-code environment with AI support for building and testing vehicle control logic. Enables engineers to rapidly create, iterate, and deploy control behaviour across fleets of uncrewed platforms. Used by defence customers developing and operating ESOX-powered systems.
• Digital Twin 2.0 Simulation environment in which the same control software runs on both hardware and virtual model with accurate 3D terrain, weather, ballistics, urban environments, and adversary behaviour. Used for virtual testing, AI training, and continuous improvement of ESOX-powered platforms.

Partnerships

Four partnerships are on record, tiered core and minor.

• Donut LabcoreTechnology or Integration · 6 January 2026Defense-specific licensing framework partnership for solid-state battery technology. Donut Lab developed the world's first production-ready all-solid-state battery (400 Wh/kg, 5-min charge, 100,000 cycles). ESOX deploys this technology across military and security applications under a defense-specific licensing arrangement. Technology originated from Nordic Nano in which Donut Lab is an investor.
• ESOX AerocoreStrategic or Co-development Partner · 1 October 2025Acquisition of Finnish UAS specialist ESOX Aero as part of group formation. Includes specialist autonomous vehicle test and development facility near Helsinki for research, prototyping, and system validation. Markus Kantonen, formerly Managing Director of ESOX Aero, leads ESOX Group's unmanned projects.
• Verge MotorcyclesminorStrategic or Co-development PartnerSister company within the Donut ecosystem. Verge Motorcycles is the first company to incorporate Donut Lab's solid-state battery technology into motorcycles (Verge TS Pro, Q1 2026). Shares technology lineage with ESOX Group.
• NATO and Allied Defense PartnerscoreStrategic or Co-development PartnerActive discussions with NATO, defense ministries, contractors, and major defense technology partners about future programmes. Company positioned as a trusted partner for NATO-aligned defense electrification.
