A growing number of natural disasters led to a 2000% increase in climate insurance claims since the 1970s, reaching $630b worldwide in the 2010s. Continued acceleration will lead climate insurance systems to collapse unless prevention is implemented. Mitigrate is a ClimateTech SaaS startup generating fully automated analyses leading to prioritized preventive measures for reducing climate damages on real estate, starting with flooding, to be extended to other risks (drought, heat, wildfire, landslide, biodiversity, wind). Thanks to high-resolution satellite images, our map-based AI models, and optimization algorithms predict how 50+ climate-positive prevention measures can be implemented to reduce risk. Business value stems from reducing risks on individual assets and prioritizing preventive measures within large portfolios of commercial & residential real estate. Since 01/01/23, the EU Taxonomy has made prevention mandatory for insurers throughout Europe.
