Sol.One

What Sol.One does

Sol.One (Sol1 BV) is a Belgian aerospace company founded in 2014 and headquartered in Bruges, with 11-50 employees. The firm builds safety-critical avionics for UAVs, eVTOL aircraft, and manned platforms, anchored by a proprietary "Sol" high-level modeling language and toolchain that automatically generates DO-178C DAL A certified software binaries — claimed to reduce manual certification effort by 90%. The product portfolio spans the full avionics stack: SolOS (DAL A real-time operating system), SolAero (DO-254 DAL A hardware), SolPi (DO-178C OS for UAV), SolFCC (flight control computer), SolFTS (flight termination/geocaging), SolDMS (datalink and data management supporting multiple protocols and backbones including Starlink, 5G, and radio), SolTLSS (takeoff/landing safety), and SolGCS (DAL B certified ground control station at €49,500). The company also manufactures the Saboteur, a long-range (400 km) military quadplane UAV with Thales FZ 70mm strike capability and swarm coordination of 200+ drones, restricted to approved governmental buyers. Certifications include EASA/FAA DAL A/B, DO-254, DO-160G, NATO STANAG 4586/4609/4671, EuroCAE ED-311, and RTCA DO-356A SAL 3.

Sol.One generates revenue through three primary channels: (1) hardware sales of avionics LRUs (SolAero, SolGCS, SolDMS, SolFTS, SolTLSS) and the Saboteur UAV platform to aircraft manufacturers, UAV integrators, and government buyers; (2) software licensing of the Sol language/toolchain for automated DO-178C certification; and (3) professional services for custom avionics development, including fixed-price conversion of Simulink models to certified applications and conversion of English specifications into DAL A certified software on multi-year contracts. Go-to-market is exclusively enterprise field sales via direct engagement, with the Saboteur restricted to approved governmental buyers and most pricing opaque (SolGCS at €49,500 is the only publicly listed price).

The customer base is concentrated on European defense and research: Belgian Defence is the primary operational military customer, while most other relationships (Thales Belgium, Intersoft Electronics, Milrem Robotics, Avilus, Airbus, Tekever ASDS, TUM, Royal Military Academy of Belgium) are consortium partners in EU-funded programs (iMUGS, iMEDCAP, IMBALS under Horizon 2020/Horizon Europe, and RAVN under DEFRA). The company is led by CEO Filip Verhaeghe and has announced plans for an IPO on Euronext Paris in 2026, with due diligence currently underway with a leading French financial services group.

Broad incumbents

• Vector Informatik: Large German embedded software tools vendor serving automotive and aerospace with AUTOSAR, certification, and testing tools. Incumbent provider of safety-critical development toolchains that Sol.One competes against in adjacent verticals.
• Airbus: European aerospace prime that partnered with Sol.One on the IMBALS program. Larger incumbent with broad UAV, eVTOL, and certified avionics capabilities that Sol.One supplies into rather than directly competes with at scale.

Emerging players

• DroneShield: Australia-listed counter-UAS provider using RF detection, radar, and soft/hard-kill defeat capabilities. Closest public pure-play comparator to Sol.One's RAVN C-UAS architecture.
