Moody’s is an initial supporter of Oasis SaaS: enterprise grade technology operated through an industry ownership model to remain immune to acquisition risk
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 robust technology and operated through an industry ownership model to remain immune to acquisition risk, Oasis SaaS is targeting the delivery of enterprise-scale performance. The platform aims to 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 is designed to help risk carriers improve their view of risk to increase profitability and avoid unwitting accumulation risk, and aims to help brokers better serve their customers.
Moody’s is working closely with Oasis SaaS in the integration with its Intelligent Risk Platform (IRP). The collaboration supports customer choice by facilitating access to Oasis models delivered through Oasis SaaS in a vendor-neutral environment, with the scale, breadth and functionality of the Moody’s platform. For IRP users, the integration with Oasis SaaS brings the ability to unify access to cat modeling from multitude of vendors under one system, simplifying expensive data conversion and systems integrations work necessary to utilize these additional models.
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.
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.”
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), said: “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.”
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.”
