Why we’re building this
The valuation platform actuaries would build for themselves.
The legacy tools were built in an era when power trumped usability — batch processing, single-user workflows, and the assumption that actuaries would tolerate complexity because there was no alternative. ActuarialOS matches their depth while rebuilding the experience from scratch.
Data first, not formulas first
Legacy tools force you to configure the plan spec before you can even look at the data. We let you import, clean, and validate census data immediately — because in practice that’s where 60% of valuation time goes.
Corrections are tracked, not hidden
When you fix a DOB or fill a missing benefit, the original isn’t overwritten. Every version is kept as a snapshot with a full audit trail — the way ASOP 41 expects.
The actuary stays in control
Not a black box that emits a number. A transparent engine where an EA can trace any liability figure back to the participant, the formula, the assumption, and the data that fed it.
Modern technology, actuarial rigor
Modern tooling is a means, not an end. Every feature is judged by one question: does this help an actuary produce a more accurate valuation, faster, with better documentation?
Where it comes from
Built by people who spent a decade inside the work.
ActuarialOScomes out of more than ten years in pension actuarial work: valuations, census data, and the spreadsheets that hold them together. It is the tool we wanted on our own desks. Faster than the systems we learned on. Direct about how a plan is set up and run, with the power in the user’s hands rather than behind a vendor’s configuration screen. And built so that, as it matures, AI can take on the setup and re-run work while the actuary’s time goes to judgment.
