Actuarial models you can open, read, and validate.
Open-source modelling engines for life insurers — methodology, code, and validation evidence, all in the open. Take them for free. Or have them fitted to your business.
Open by design
A model your own actuaries can read, run, and test is easier to defend than a black box — not harder.
Validated, not asserted
Every model ships with its methodology, its regression harness, and a plain statement of its limitations.
Built by an actuary
Twenty years in life-insurance modelling — including six inside the vendor whose software most of the industry runs on.
Models
- Gnanam ESG
An open economic scenario generator for life insurers: interest-rate, equity, and credit models with a joint portfolio layer — each with a citation-grade methodology document and a bit-identity regression harness.
Writing
- Build vs buy after the cost collapse
The cost of building a production-grade actuarial engine has collapsed. The cost of trusting one has not. What that asymmetry means for insurers weighing bespoke models against commercial suites.
