Actuarial Modeling and Automation for Modern Life Insurers

Montoux is the leading actuarial modeling and automation platform designed to make actuaries more effective.

Over the years, a technology gap has developed creating a disconnect between the work actuaries have trained for and the work they actually do. This is largely due to legacy actuarial systems struggling to handle the complexity of change in regulatory and market conditions.

Montoux bridges this gap by automating the manual, labor intensive processes that are common in legacy systems. Montoux’s cloud-native platform combines and integrates capabilities from the best of existing open technology, such as Jupyter, VSCode and Python, combined with new technology native to Montoux.


With a platform built at the intersection of flexibility and control and a dedicated team of customer success and product experts, Montoux works alongside its customers to configure actuarial workflows to fit the demands of large actuarial teams. The platform is grounded in actuarial science, data science, and AI-based optimization algorithms, helping insurers drive significant value in new business and in-force portfolios while allowing them to operate smarter, faster, and leaner.

Today, our customers include several of the world’s leading insurance providers across the United States, Asia Pacific, and the United Kingdom.
