Swiss Re, AON and Moody’s are initial supporters of Oasis SaaS: capital-markets-grade technology and operated through an industry ownership model to remain immune to acquisition risk.

London, 13 February 2026 – Oasis Loss Modelling Framework (Oasis LMF), the not-for-profit open source catastrophe modelling platform, today announced the launch of Oasis Software as a Service Limited (Oasis SaaS) – an industry-owned, vendor-neutral platform designed to preserve independence and customer choice in catastrophe modelling. Built on robustntechnology and operated through an industry ownership model to remain immune to acquisition risk, Oasis SaaS delivers enterprise-scale performance. The platform will offer seamless access to Oasis model providers and coverage across 300+models. These will include Impact Forecasting, JBA, Fathom, Renew Risk, ARA and others. This will help risk carriers improve their view of risk to increase profitability and avoid unwitting accumulation risk and will help brokers better serve their clients.

Ratings Agency Moody’s is also working closely with Oasis SaaS to ensure seamless integration with its Insurance Risk Platform (IRP). The collaboration safeguards customer choice by maintaining full access to Oasis models in a vendor-neutral environment, while reinforcing support for independent providers. For IRP users, it enhances value by combining the flexibility of Oasis with the breadth and functionality of Moody’s platform.

The initiative is 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 Four Theorem as the service provider backbone, Oasis SaaS uses a cloud-native architecture to unlock elastic scaling and major performance gains over legacy systems.

The independent offering of Oasis SaaS represents a significant milestone for the industry. By providing a neutral, industry-owned platform, it empowers model vendors to deliver their intellectual property securely and transparently, while enabling model consumers to access and select the most suitable models without being constrained by platform dependencies. This advancement reinforces independence, promotes choice, and drives innovation across the catastrophe modelling ecosystem
