Insurance Loss Estimation Engine

A multi-peril loss estimation platform that calibrates and blends commercial CAT model outputs with internal claims experience for sharper portfolio loss estimates.

Perils

XGBoost calibration

Method

Post-event response packs

Problem & use case

Single-vendor CAT model reliance led to systemic bias and large deviations vs realized losses.

Solution & engineering approach

An XGBoost-based calibration layer on top of RMS RiskLink outputs, trained on historical event-vs-actual loss data.
