What Sisprobe does

Sisprobe is a French geophysical services firm, founded in 2017 and headquartered in Seyssins, that operates as a subsidiary of Egis Group under the brand 'Sisprobe by Egis'. The company specializes in subsurface imaging and monitoring using ambient noise surface wave tomography — a passive seismic method that captures ambient ground vibrations via wireless sensors and reconstructs subsurface images without deploying active seismic sources. Its core technology stack combines passive seismic interferometry, surface wave and body-wave tomographic inversion, time-lapse monitoring, seismic event detection and location (STA/LTA, beamforming, template matching, focal mechanism, double-difference relocation), and HPC-based processing hosted on the French mesocenter at University Grenoble-Alpes, where the company is physically hosted alongside its scientific committee of leading researchers.

Sisprobe sells professional services across four core lines — seismic data acquisition, seismic data processing, earthquake and seismic monitoring, and consulting — and applies them across multiple verticals: mineral exploration, geotechnical engineering, geothermal resources, CO2 storage monitoring, tailings storage facility monitoring (in collaboration with Silixa and HydroResearch using Distributed Acoustic Sensing and optical fibres), and cover mapping. The company positions itself as the world leader in noise-based subsurface imaging, citing reference pricing of approximately USD50 per km² for cover mapping and depth penetration from tens of metres to several kilometres across survey areas up to 100 km². Customers include mineral exploration firms, tailings storage operators, geothermal resource companies, and CO2 storage operators across France, Netherlands, USA, Canada, and Australia.

The go-to-market is enterprise field sales: Sisprobe delivers services directly to clients through a small, specialist team of approximately 10 employees, including field technicians and internationally recognized experts, supported by dedicated business developers for Europe and the Americas and offices in Grenoble and Los Angeles. Revenue is generated on a project and unit-pricing basis (e.g., USD50 per km²) under the parent Egis Group's global infrastructure, energy, and engineering platform.
