Alliant Insurance Services

What Alliant Insurance Services does

Alliant Insurance Services is a privately held specialty insurance brokerage founded in 1925 and headquartered in Irvine, California, operating from more than 100 offices across North America. It serves middle-market and large enterprise clients with a diversified portfolio spanning commercial property and casualty, employee benefits, reinsurance, specialty lines, and captive program management, placing more than $55 billion in annual premiums and reporting approximately $5.7 billion in revenue. Its core offerings combine traditional brokerage placement with proprietary analytics platforms such as FleetLytics (transportation telematics and claims analytics) and Cyber Response One (pre-breach cyber risk and incident response services), positioning the firm beyond pure intermediation toward higher-value risk advisory and data-enabled services. The business model is primarily commission- and fee-based, supplemented by contingent profit participation from carriers, with a 100% employee stock ownership plan (ESOP) and producer equity participation designed to drive retention and recruitment in a relationship-driven industry. Alliant pursues growth through a combination of organic producer hiring, tuck-in acquisitions (e.g., Assured Health Group, HMS, Highpoint Insurance Group, Laredo Commercial Insurance), geographic expansion into underserved corridors, and product innovation in analytics and cyber services, while operating as the largest privately held U.S. insurance brokerage and ranking among the top five global brokers.
