SageSure is the largest residential property insurance managing general underwriter (MGU) in the United States. Founded in 2009, the company writes home, flood, earthquake and commercial coverage on behalf of highly rated carrier partners, focusing on homeowners and small businesses in catastrophe-prone coastal markets where legacy carriers have pulled back. It manages more than $3.2 billion in premium and protects nearly one million homes across 16 coastal states, including Florida, Texas, Louisiana, Mississippi, Alabama and the Carolinas.
Technology is central to how the business is run. SageSure operates proprietary technology platforms and a multi-carrier platform designed to ensure continuous capacity and long-term financial stability. Its technical work spans data science, catastrophe risk underwriting and multi-carrier platform technology, applied to pricing and risk selection in markets exposed to hurricanes, floods and earthquakes.
The company employs more than 1,300 people across 13 offices in the United States. Its underwriting expertise has drawn industry recognition for excellence in catastrophe risk management, and the firm has appeared on the Inc. 5000 list of fastest-growing companies multiple times.
