Builds passive RF drone detection systems and counter-UAS platforms for military and law enforcement customers worldwide.
Builds the first software-defined, CMOS-native hyperspectral imaging chip with sub-10nm spectral accuracy, small enough for wearables and smartphones but designed to detect concealed threats and substances for defence customers. Raised €5.6M in September 2025 and won a Swedish Defence Agency innovation contract in November 2025.
Terrain-referenced, multimodal navigation and perception engineered for GNSS-denied and comms-denied environments. Founded by the inventor of SSH, the company holds 30+ AI and computing patents and runs EU-sovereign training infrastructure on its own compute.
DA-Group provides advanced electronics and high-technology systems for defence, aerospace and industry, including EW testing, degaussing and resilient navigation products.


Glasses-free mixed reality for defence vehicles, aircraft and helmets, turning windshields into 3D lightfield displays fused with thermal, radar and battlefield management data. Raised €13.9M led by Google Ventures, partnered with Patria, Supacat, General Dynamics and Aechelon.
ElFys manufactures highly sensitive photodiodes with external quantum efficiency greater than 96% using patented black silicon induced junction technology for light sensing applications.
Aalto University spin-off developing ultralight metasurface thin-film antennas for UAVs, satellites and ground systems. Raised €1M pre-seed in 2025 to commercialise antennas for next-generation C-UAS radar, jamming and tactical communications.
Tactical GNSS-denied navigation built from European commercial components. Fuses GNSS, IMU and odometry with jamming and spoofing detection, integrating with SitaWare Frontline, ATAK and NATO Generic Vehicle Architecture.
Develops optronics, night vision, fire control, surveillance and critical communications systems for defence, security and industrial users.
