Economic and Capital Modelling

tyche® has been designed to empower actuaries struggling with large-scale, unwieldy models, including capital models.


We’re also developing a new economic scenario generator that will simplify user control of the scenario output – and particularly supports nested scenarios.


tyche® is a "next-generation" actuarial modelling platform offering state-of-the-art analytic capability, ground-breaking speed, "ease-of-use”, flexibility and robustness.
