- Founder Jack Byrne had previous success with Fireman's Fund.
- The company's origins are linked to residual assets from Fireman's Fund.

In 1991, Byrne and other investors organized Fund American Enterprises Inc., which served as the initial structure.

The original business model involved acquiring, operating, and divesting businesses within the insurance and financial sectors. A pivotal moment in the White Mountains Company history was the 2001 acquisition of CGU's U.S. insurance operations, renamed OneBeacon, which was significantly supported by financing and reinsurance from Berkshire Hathaway. This transaction was instrumental in solidifying the company's position in the property and casualty insurance market. In 1999, the company officially rebranded as White Mountains Insurance Group, Ltd. and strategically relocated its operations to Bermuda, a key international insurance hub.
