What GScan does

GScan OÜ is an Estonian deep-tech company founded in 2018 that has commercialized cosmic ray Muon Flux Tomography (MFT) for non-destructive inspection of large-scale infrastructure. The technology uses naturally occurring muons from cosmic rays, detected by proprietary sensor arrays, combined with AI/ML-based reconstruction algorithms to image the internal density and reinforcement layout of concrete, steel-reinforced, and other dense structures without radiation sources, drilling, or destructive sampling. The company holds 10 patents across 3 patent families filed in 5 jurisdictions and operates from offices in Tallinn, Tartu, Cambridge (UK), and Munich (Germany), with a team of 50+ including 8 PhDs.

The platform is applied to bridges, tunnels, highways, nuclear facilities, and heritage structures, where conventional inspection methods are slow, costly, or disruptive. Customers include national infrastructure owners such as National Highways (UK), Rijkswaterstaat (Netherlands), and the Estonian Transport Administration, alongside tier-one engineering services firms including AtkinsRéalis, Jacobs, Heijmans, and FM Conway, with notable deployments extending into the nuclear sector at Sellafield. Technology credibility is reinforced by validation work with CERN.

GScan generates revenue primarily through project-based scanning engagements, longer-term structural monitoring deployments, and a growing software/data analytics layer around its reconstruction algorithms. The company has previously raised €6M+ in equity and approximately €12M in non-dilutive grants, and is targeting a €7.5M Series A in May 2026 to scale commercial operations, expand the DACH presence, and accelerate product development. Reported 2025 revenue was €1.6M, with management targeting roughly a doubling in 2026 as the sales pipeline converts and new geographies ramp.

Core offering

GSscan manufactures and sells the muonFLUX family of Muon Flux Tomography (MFT) scanner systems that detect naturally occurring cosmic-ray muons to produce 1mm-resolution 3D density maps of internal structures at penetration depths exceeding 10 metres. The offering is delivered in two industry-tuned variants: muonFLUX Infra AI for civil engineering inspection of bridges, tunnels, and buildings, and muonFLUX Nuclear AI for nuclear reactor decommissioning in high gamma-ray background environments, with a cloud-based AI software platform outputting CAD/BIM/GIS-compatible data. The company also provides on-site scanning services, engineering analysis, and recurring structural monitoring to public infrastructure owners and engineering consultancies.

Product overview

GScan offers a unified hardware-plus-AI-software product line built around its proprietary Muon Flux Tomography (MFT) technology, branded collectively as muonFLUX. The core muonFLUX platform is delivered in two industry-tuned sub-products — muonFLUX Infra AI for civil engineering inspection of bridges, tunnels, and buildings, and muonFLUX Nuclear AI for nuclear reactor decommissioning — both sharing the same modular 1m x 2m detector array hardware and cloud-supported AI reconstruction software. The platform is supported by an online demo environment (GScan MFT Demo Platform at demo.gscan.eu), a gated video tutorial series for deployment teams, and an intuitive cloud-based user interface that outputs CAD/BIM/GIS-formatted 3D density reconstructions with up to 1mm resolution and 10+ metre penetration depth.

Scale indicators12 records

Recent moves7 records

Expansion highlights6 records

Direct peers

• Lynkeos Technology: UK-based startup commercialising muon imaging for nuclear waste and decommissioning inspections. Direct competitor to GScan in the muon tomography category, with overlapping patent ambitions and shared end customers in the UK nuclear sector.
• Ideon Technologies: Canadian company deploying muon tomography for subsurface imaging in mining and geophysics. Closely comparable to GScan's muonFLUX hardware platform but focused on resource extraction and geological exploration rather than infrastructure inspection.

Broad incumbents

• Mirion Technologies: Large US-listed radiation detection and nuclear measurement company that acquired Decision Sciences International's muon tomography business. Provides radiation detection instruments and portals across nuclear, security, and medical markets — overlapping with GScan's Nuclear AI product line as a much larger incumbent.
• Evident (formerly Olympus Industrial / Eddyfi Technologies): Global industrial NDT equipment and inspection solutions provider covering ultrasonic, eddy current, phased array, and visual testing. Competes indirectly with GScan by supplying the entrenched NDT methods (ultrasonic, GPR) that muon tomography displaces for deep concrete inspection.
• Waygate Technologies (Baker Hughes): Industrial NDT and inspection equipment provider offering remote visual inspection, ultrasonic, and radiographic solutions across energy, aerospace, and infrastructure. Comparable as a broad incumbent in the same enterprise NDT procurement budgets GScan targets.

Emerging players

• Creaform (AMETEK): Provider of 3D scanning and measurement technologies for industrial inspection. Comparable to GScan in the 3D reconstruction and dimensional measurement use cases but uses optical/scanning laser technology rather than cosmic-ray muon detection.
• Senceive: UK-based provider of wireless structural health monitoring sensors and platforms for rail, civil, and geotechnical infrastructure. Comparable as a structural-health-monitoring vendor serving the same infrastructure asset owners, though complementary rather than competing directly in subsurface imaging.
• Sixense (Vinci Group): Engineering group providing structural and geotechnical monitoring, asset integrity, and digital twin solutions for major infrastructure projects. Overlaps with GScan on infrastructure owner relationships and the structural health monitoring value proposition.

Others

• BAM (Bundesanstalt für Materialforschung und -prüfung): German federal materials research and testing institute that has validated GScan's muon tomography against GPR and ultrasonic methods. Relevant as a non-commercial peer that sets the technical benchmark GScan must clear to win DACH public-sector contracts.
• Kuraray: Japanese specialty chemicals and materials company listed as a GScan partner and adjacent to the post-tensioned bridge tendon materials market. Included as an ecosystem/adjacent peer rather than a direct competitor.
