Overview
Chubb Limited is a Swiss-incorporated global insurer with six reported segments spanning North America commercial and personal P&C, agricultural insurance, international general insurance, global P&C reinsurance, and primarily Asia-focused life and A&H. Its moat is mainly distribution plus execution: deep broker/agent channels, a globally licensed footprint for locally admitted multinational programs, and service/claims capabilities positioned as differentiators. Strong financial strength ratings and capital support capacity and counterparty confidence, especially in commercial and reinsurance lines. Key risks are underwriting-cycle volatility, catastrophe and climate-related loss uncertainty, regulatory constraints (notably crop and distribution), and competition from digital distribution and alternative reinsurance capital. market_cap_usd is a proxy (non-affiliate market value) as of 2024-06-30.

Curation & Accuracy
This directory blends AI‑assisted discovery with human curation. Entries are reviewed, edited, and organized with the goal of expanding coverage and sharpening quality over time. Your feedback helps steer improvements (because no single human can capture everything all at once).
Details change. Pricing, features, and availability may be incomplete or out of date. Treat listings as a starting point and verify on the provider’s site before making decisions. If you spot an error or a gap, send a quick note and I’ll adjust.
