The platform

Built like audited financial software, not a web app.

The moat for legacy tools isn’t features — it’s trust. ActuarialOS earns it by making every calculation inspectable and every result reproducible.

Every number is reproducible

Valuations read a frozen triple — census, assumptions, plan structure — from the plan-year record. Re-run a signed year and it reproduces to the dollar. No drift, no 'which file was final'.

The actuary stays in control

No black box. Trace any liability figure back to the participant, the formula applied, the assumption used, and the data that fed it. When you sign the report, you can defend every line.

Data first, not formulas first

Import, clean, and validate census data immediately — because 60% of valuation time is data, not calculations. Corrections are tracked as snapshots, never overwritten.

Modern workflow, actuarial rigor

One account across the add-in, the web tools, and the platform. Built to match ProVal and Quantify on depth while rebuilding the experience around how actuaries actually work today.
