Oasis Loss Modelling Framework (Oasis LMF), a not-for-profit open source catastrophe modelling platform, has launched Oasis Software as a Service Limited (Oasis SaaS) – an industry-owned, vendor-neutral platform designed to preserve independence and choice.
Oasis SaaS leverages its robust technology to target the delivery of enterprise-scale performance, while operating through an industry ownership model to remain immune to acquisition risk.
The platform is designed to provide risk carriers with seamless access to over 300 Oasis model providers, including names like Impact Forecasting, JBA, Fathom, Renew Risk, and ARA.
This extensive coverage is intended to improve risk carriers’ understanding of risk, leading to increased profitability and the avoidance of unintended risk accumulation. Furthermore, it aims to enhance the service brokers can offer their customers.
Michael Steel, Head of Insurance Solutions, Moody’s, said: “We welcome this industry-sponsored initiative to create an independent platform for accessing third-party models which dovetails with our own platform, data, applications and models.
“This is designed to enable a simplified path to workflow integration for our insurance customers. Oasis SaaS provides a neutral, multi-vendor environment with the aim of safeguarding our customers’ choices of the best models for each portfolio.”
Dickie Whitaker, Chair of Oasis SaaS, said: “This is a pivotal moment for the industry. Oasis SaaS has been created to ensure catastrophe modelling remains independent, industry-owned and free from consolidation risks. With industry funding, and a roadmap to expand to more than 300 perils from up to 20 model providers, we are delivering a solution built by the market, for the market. Our commercial launch in Q3 2025 marks the start of a transformation that will make catastrophe modelling more resilient, innovative and accessible than ever before.”
Moody’s is integrating Oasis SaaS into its Intelligent Risk Platform (IRP). This collaboration offers IRP users access to Oasis models through a vendor-neutral environment, leveraging the Moody’s platform scale.
This integration unifies access to catastrophe modelling from multiple vendors within one system, reducing the need for costly data conversion and system integration.
The initiative is also supported by Amazon Web Services (AWS), whose infrastructure enables flexible deployment, cost efficiency and improved sustainability via on-demand computing, with cloud credits accelerating initial adoption.
Developed with fourTheorem as service provider backbone, Oasis SaaS uses a cloud-native architecture to unlock elastic scaling and major performance gains over legacy systems.
Paul Shedden, Global Head of Advanced Risk Analytics for Risk Capital, Aon, said: “Aon is committed to providing clients with access to the best catastrophe modelling capabilities in the market to analyse their underlying risk.
“Oasis SaaS offers a true multi-vendor, multi-model environment, enabling Aon to deliver a broader range of view of risk, thus empowering clients to make more informed decisions for their business.” Sibylle Steimen,
Chair of the Oasis LMF Board (Allianz), commented: “Recent mergers and acquisitions have significantly reduced the market’s choice of catastrophe modelling providers, heightening the risk of consolidation-driven dependency. The ability to maintain independence in this space has never been more critical.
“For more than 12 years, Oasis has demonstrated that industry-led solutions can thrive outside commercial ownership. With Oasis SaaS, we are reinforcing that principle – protecting neutrality, ensuring transparency, and giving the market long-term confidence in its modelling infrastructure.”
