What Tellus Environment does
Tellus Environment is a France-based geophysical survey and data processing firm specializing in subsurface risk assessment, buried object detection, and underground/seabed mapping. The company combines multi-sensor data acquisition (magnetometry, ground-penetrating radar, electromagnetics, sub-bottom profiling, and Lidar remote sensing) with its patented Magsalia mathematical inversion process and proprietary Tellus Map 3D visualization software to produce 2D and 3D tomographies for decision support. Drone-based magnetic survey capability extends its reach into difficult terrain at scale. The firm serves enterprise and government clients across three primary verticals: construction and civil engineering (UXO risk for infrastructure projects, buried utility detection, cavity mapping), energy and natural resources (offshore wind UXO clearance, mining exploration, dam reservoir characterization), and archaeology (preventive prospection and Lidar-based heritage mapping). Notable customers include EDF EN, ENGIE, Enedis, Suez, SIAAP, the Royal Commission for Al'Ula, the French Service d'Infrastructure de la Défense, and the ports of Saint-Nazaire and Marseille.
The business operates as a sole proprietorship (micro-entreprise EI, SIRET 75218282400017) owned by Geoffroy ETAIX, with 1-10 employees and dual offices in Bruz and Guichen, France. Revenue is generated exclusively through project-based professional services engagements quoted per scope, with no software licensing or subscription model; clients pay for data processing volume or zones of interest. Go-to-market is direct enterprise sales supplemented by content marketing via case studies, a bilingual French/English website, and professional social channels. The company has executed internationally in France, Saudi Arabia, and Germany, and maintains minor technology partnerships with FUGRO EMU (marine survey) and Posselt & Zickgraf Prospektionen (German geomagnetic surveys). Recent productization includes drone-based aerial magnetic surveys and the integration of machine learning for automatic target detection in GPR radargrams.
No external funding, M&A activity, or material leadership changes are documented. R&D is referenced as ongoing across next-generation sensors and data processing methods, and the Magsalia patent remains the principal intangible asset underpinning the technical moat.

Tellus Environment product offering
Product offeringCore offering
Tellus Environment provides geophysical data acquisition, processing, and mapping services for subsurface risk assessment. The company combines multi-sensor field surveys (magnetometry, GPR, electromagnetics, sub-bottom profiling, Lidar) with its patented Magsalia mathematical inversion process and proprietary Tellus Map 3D visualization software to detect and characterize buried objects including unexploded ordnance (UXO), infrastructure, cavities, and archaeological features at depths from 0 to 10m+.
Product overview
Tellus Environment is a geophysical survey and data processing company offering a portfolio centered on two proprietary software products: Magsalia© (a patented mathematical inversion and data fusion process) and Tellus Map (3D mapping software). These core technologies process data from multiple geophysical sensors (magnetometers, GPR, electromagnetics, Lidar, satellite imagery) to produce 2D and 3D visualizations of ground, underground, and seabed. The company delivers these through service offerings including pyrotechnical diagnosis, archaeological prospecting, UXO detection, drilling securing, mining exploration support, buried network detection, cavity detection, drone surveys, and Lidar imaging.

Products and services
- Magsalia (Mathematical Inversion Process) Patented mathematical inversion and data fusion process that processes raw geophysical survey data (magnetic, GPR, electromagnetic, Lidar, multispectral) into 2D/3D tomographies and heat maps for subsurface visualization and target detection.
- Tellus Map (3D Mapping Software) Proprietary 3D decision-support mapping software that processes geophysical data to produce 2D and 3D georeferenced maps under GIS, used for target identification, confirmation, and visualization of underground and seabed structures.
- Pyrotechnical Diagnosis Services Surface UXO/REG detection service combining magnetometry, GPR, and electromagnetic methods with Magsalia processing to discriminate buried metallic objects, characterize anomalies, and reduce remediation costs for construction and infrastructure clients.
- Pyrotechnical Work Securing (Sécurisation pyrotechnique de travaux) Non-intrusive survey service combining magnetometer and GPR to identify and map UXO risks before drilling or construction, enabling selective risk zone designation and rapid de-risking of project sites.
- Drilling and Borehole Securing (Sécurisation de forages et sondages) Real-time pyrotechnical securing of boreholes using radar and borehole probes to detect suspect objects in real-time during drilling operations at depths up to 5m.
- Archaeological Prospecting Services Geophysical and optical prospecting (magnetometry, GPR, Lidar, thermal, multispectral) for archaeological site mapping without surface alteration, supporting excavation guidance and preventive archaeology research institutions.
- Marine UXO Detection Services Detection and classification of marine unexploded ordnance using marine magnetometers and Magsalia processing to rationalize magnetic survey echoes and reduce target lists by factor of 35 for offshore wind and seabed construction clients.

- SOCOTEC: French testing, inspection, and certification group providing geotechnical, environmental, and construction-related services across the asset lifecycle. Comparable as a French incumbent addressing overlapping construction/utility clients with adjacent diagnostic offerings.
- AECOM: Global engineering, environment, and infrastructure services firm with practice areas in environmental remediation, site investigation, and construction support. Overlaps with Tellus on subsurface risk and environmental consulting for infrastructure and energy clients.
- WSP: Global engineering and professional services consultancy with strong environmental, geotechnical, and transport-infrastructure practices. Comparable as a broad incumbent offering site-investigation and subsurface-related services to similar end customers.
- Fugro: Dutch global leader in geo-data services covering offshore site characterization, UXO risk management, and seabed surveys for offshore wind and oil & gas. Overlaps with Tellus on UXO detection and offshore wind survey workflows (already a partner-adjacent on the Fécamp project via Fugro EMU).
- Ramboll: International engineering, design, and consultancy with substantial environment, water, and energy practices in Europe. Comparable on environmental site assessment and infrastructure pre-construction advisory, with similar European client footprint.
Direct peers
- Geoter: French provider of geotechnical and geophysical site investigations for construction, environment, and infrastructure projects. Directly comparable in service mix (subsurface characterization, cavity detection, infrastructure pre-survey).
- Compagnie Générale de Géophysique (CGG): French-headquartered global provider of geophysical services and equipment for subsurface imaging across oil & gas, mining, and environmental markets. Closest direct peer to Tellus on the data acquisition and processing core, though much larger and more focused on upstream E&P.
- Geophysique Appliquée (GA): French geophysical services firm offering near-surface surveys (magnetometry, GPR, electromagnetics) for construction, environment, and archaeology. Highly comparable to Tellus in scope, scale, and end-market mix, with similar multi-sensor workflow.
Others
- BRGM (Bureau de Recherches Géologiques et Minières): French public geological survey institution providing subsurface data, mapping, and expertise across construction, environment, mining, and heritage. Comparable as a French geoscience reference and indirect collaborator rather than direct competitor; operates both as a data provider and technical advisor.
