About Us

We are a leading carrier of specialty insurance products distributed exclusively through wholesale brokers. Our products include insurance solutions for property, casualty, professional liability, and management liability risks. Our broker relationships span coast to coast, enabling us to provide coverage to thousands of companies nationwide. 

Specialty Insurance​

From our 1988 founding to Alleghany Corporation’s 2003 acquisition of RSUI, to becoming a Berkshire Hathaway company in 2022, we have led the specialty insurance market. We take an entrepreneurial approach to underwriting, identifying opportunities in risks that the standard market can’t accommodate. Challenges like cyber security, natural disasters, and long-tail business are our sweet spot. 

Wholesale Only​

We rely on long-standing relationships with trusted wholesale brokers to distribute our products. Acting as an intermediary for the retail agent, RSUI’s wholesale partners have direct access to specialty carriers and the ability to navigate a complex and ever-changing market. Wholesale broker and carrier relationships are integral when finding a solution for a hard-to-place risk. 

There are a lot of specialty insurance solutions in the marketplace, but RSUI has earned a reputation that stands out from the rest.
