We are the CelsiusPro Group, an award-winning insurtech group dedicated to helping both private and public organisations to understand and mitigate the adverse financial impact of climate and NatCat risks.

Our climate risk consulting services round our holistic solutions suite.

Business is underwritten by NatCatPro, utilizing our proprietary technology platform. We partner with insurance brokers to serve corporates and public-sector organisations seeking financial coverage against climate and NatCat perils.
