What RSS-Hydro does

RSS-Hydro SARLS is a Luxembourg-domiciled private limited company (SARLS) headquartered in Kayl that builds geospatial intelligence products and services for flood and wildfire risk management. The company was founded by Guy Schumann, who serves as CEO, and operates with an international team of approximately seven core professionals comprising hydraulic engineers, an EO/ML expert, a geoinformatics specialist, and an EO data analyst. Its portfolio is anchored by four named technical products—SafeCity (an award-winning municipal flood modeling platform featuring 3D Digital Twin visualization, underground network integration, scenario testing, and forecasting), FloodSENS (a machine-learning algorithm that maps flood extents globally from satellite imagery and topographic data), FireSENS (a near-real-time thermal-data wildfire risk assessment tool with demographic overlays), and HydroSENS (a Sentinel-3-based soil moisture and water stress product downscaled to 20m resolution)—alongside site-specific flood modeling consulting and a government-accredited Research and Education Department (RED) that conducts applied R&D in Earth observation and risk science.

The company monetizes through two primary streams: project-based professional services for flood risk assessment, urban design review, and environmental impact studies, and licensing of the SafeCity platform to enterprise and public-sector clients. Customers span municipalities, utilities, engineering firms, financial and insurance institutions, and humanitarian organizations. Go-to-market is consultative and sales-led, relying on direct contact (phone, email, web form) supplemented by event-driven engagement such as mapathons and the IMS Challenge Day. The offering is differentiated by the integration of proprietary ML algorithms with multi-source Earth observation data and a partnership ecosystem that includes the European Space Agency, the Luxembourg Space Agency, the Luxembourg National Research Fund, MSF, CEOS, and African research institutions (CILSS AGRHYMET, CRREBaC), supporting deployments in West and Central Africa alongside European engagements.

The business model is constrained by a small headcount and reliance on a founder-led team with no disclosed external funding or institutional investors. Revenue mix leans toward lumpy project consulting with a growing but unquantified recurring licensing component via SafeCity, and the company faces concentration risk from a limited active pipeline at any given time despite horizontal diversification across customer segments. Geographic reach is global in claim, anchored by humanitarian and research partnerships across multiple continents.
