Connecting climate and financial performance
Weatherisus enables companies to analyze, understand, and evaluate their exposure to climate risks, and partners with insurers, reinsurers, and data providers around the world to protect businesses from the consequences of climate risks by designing tailored data-driven financial and insurance products.
We engage with companies to identify the climate risks they face
From supply chain to sales to end customers, we analyze these risks based on companies’ business data and our own databases, define the specific characteristics of each climate risk, and assess the short- and medium-term financial consequences to facilitate decisions.
We develop customized protection based on a bespoke climate index to offset potential losses, reduce cash flow volatility, optimize sales management, and build resilience to climate change.
We track the evolution of the risk and the value of the potential payment of the protection throughout the protection period, notify the beneficiary of our product when payment is triggered and automatically settle based on the value of climate index.

Weatherisus helps companies to map climate risks and act to adapt
Climate change and climate variability are increasing sources of operational and financial risk for many small, medium, and large companies.
With climate change, climate variability has considerably risen over the past decades and is expected to continue to rise over the next twenty years, no matter how fast GHG emissions take place. This implies that companies must act to adapt.
We track the evolution of the risk and the value of the potential payment of the protection throughout the protection period, notify the beneficiary of our product when payment is triggered and automatically settle based on the value of climate index.

Our Company
Founded in 2019 by a team of corporate risk management experts and climate scientists, Weatherisus operates from Angers and London, offering data-driven analysis and advice, and financial protection against climate risks.
The creation of Weatherisus was based on the recognition that climate risk is systemic, local, and specific and requires a new approach. The climate risk analysis we have developed is based on the cross-analysis of climate and business data and relies on a multidisciplinary team combining skills in algorithmic data processing, risk modeling, corporate finance, and climatology.
