ACTUARIAL OPERATING PLATFORM

Milliman Opensource Platform System

Turn Python actuarial models into secure, scalable production applications. Milliman Opensource Platform System is a cloud-native SaaS platform that helps teams automate actuarial modeling workflows, scale compute on demand, and use agentic AI to work with models and results.

THE CHALLENGE

Using Python models in production creates operational complexity

Many organizations develop powerful actuarial models in Python but struggle to operate them at scale. Infrastructure maintenance, security updates, workflow management, version control, and peak-period demands create ongoing operational burdens. Internal platforms often require significant investment and long-term support, diverting valuable resources away from analysis, innovation, and business outcomes.

THE SOLUTION

Deploy and scale with confidence

Milliman Opensource Platform System provides a production-ready python actuarial SaaS platform designed specifically for model execution and governance. Teams can manage inputs, configure runs, monitor performance, automate processes, and maintain complete traceability through a single web-based environment. Azure-hosted infrastructure scales automatically as demand changes, helping organizations support critical reporting and regulatory workloads efficiently. The integrated AI assistant boosts productivity, through task automation, and actuarial support.
