2025 DIAmond Award Winner 7Analytics: New Flood Model Approaches: Predicting the Unexpected through Machine Learning - A case study across Germany
7Analytics is a Norwegian technology company founded by four geologists with backgrounds in fluid dynamics and subsurface modelling from the oil & gas industry. The company was established to close a critical knowledge gap in understanding and underwriting flood risk with true precision.
7Analytics provides 1x1m flood hazard data for all flood types (pluvial, riverine, coastal, and flash floods), building-level pluvial flood scores, as well as forecasting and early warning solutions. The data is already used by property insurers in six countries for underwriting, pricing, and event response — and by banks, cities, hospitals, energy companies, manufacturers, and retailers to strengthen climate resilience and prevent loss of life and business interruptions.
In this presentation, we present a Germany-wide study conducted with Gen Re and 12 of its primary carrier clients. Our pluvial flood model demonstrates strong predictive performance against historical claims data — particularly when compared to other flood models and GDV (ZÜRS) classifications. Furthermore, our analysis of 7 million residential buildings across all 16 German states shows that portfolios with high pluvial flood exposure correlate strongly with lower insurer profitability.
