How many brands does Chubb own?
Chubb operates primarily under the Chubb master brand, with Combined Insurance and Chubb Tempest Re as subsidiary brands, plus the legacy ACE name in some international markets.

The Chubb name traces to 1882, when Thomas Caldecot Chubb and his son Percy opened a marine underwriting business in New York City. The company grew through the twentieth century into a leading US commercial insurer, adding professional liability, surety, and personal lines for affluent customers.

The modern entity formed differently. ACE Limited was founded in 1985 in Bermuda to provide excess liability and directors and officers coverage during a liability insurance crisis. Under CEO Evan Greenberg, who joined in 2001 and became CEO in 2004, ACE grew through acquisitions into a global multi-line insurer headquartered in Zurich.

In 2016 ACE acquired The Chubb Corporation for approximately $28.3 billion and adopted the Chubb name, combining ACE's international specialty platform with Chubb's US commercial and high-net-worth personal lines strength. The combined entity became the world's largest publicly traded P&C insurer.

The company has continued expanding, with significant growth in Asia where its life insurance operations are concentrated, and in specialty lines including cyber, which has become a major growth category. FY2025 marked the peak of a multi-year earnings acceleration driven by underwriting discipline, rate increases, and investment income growth.

Chubb's sustainability approach centers on climate risk management in underwriting, environmental products including pollution liability coverage, and operational emissions reduction. The company has committed to not underwriting new coal projects above defined thresholds and has set emissions targets for its own operations.

The company publishes sustainability reporting covering its investment portfolio's ESG characteristics and underwriting approach to climate transition. It does not hold B Corp or equivalent certifications typical of consumer-facing sustainability brands.
