Alliant

What Alliant does

Alliant Insurance Services, Inc. is a privately held, U.S.-domiciled insurance brokerage and risk management firm founded in 1925 (per firmographic record; company history references circa 1920) and headquartered in Irvine, California (with corporate offices also in San Diego). It operates as the fourth-largest insurance broker in the United States and the fifth-largest globally, and is the largest privately owned broker per Business Insurance's rankings. The company employs more than 10,000 professionals across 100+ U.S. offices, including over 3,700 specialized industry practitioners, and places roughly $55 billion in annual premiums (approximately $14 billion via its dedicated P&C platform), generating $5.7 billion in FY2024 revenue.

The platform is organized around 16 dedicated industry verticals (Agribusiness, Aviation, Construction, Cyber, Energy & Marine, Financial Institutions, Forest Products, Government Contracting, Healthcare, Law Firms, Life Sciences, Management & Professional, M&A, Power, Public Entity, Real Estate & Hospitality, and Transportation) supported by specialty sub-brands including Alliant Private Client (300+ specialists), Alliant Underwriting Solutions, and a Reinsurance practice. Core product lines encompass property & casualty brokerage, employee benefits consulting, reinsurance, retirement & wealth, claims advocacy, disaster recovery, and human capital consulting. Technology assets include proprietary programs such as the Alliant London Program Slip (ALPS) for A+ London property capacity, the Juno child-disability insurance distribution platform, the Conserve-A-Nation nonprofit program (with Chubb), and acquired capabilities from AnalyticsIQ providing 500 AI-powered predictive audience segments deployed via a Proximic by Comscore partnership.

Alliant earns revenue primarily through insurance brokerage commissions paid by carriers as a percentage of premium placed, supplemented by contingent and supplemental compensation tied to volume, growth, retention, and loss-ratio performance, and by professional services fees for underwriting, program administration, loss control, claims management, and consulting engagements. Distribution is sales-led through enterprise field teams organized by vertical and supported by inside-sales and acquisition-integration channels, with a flat "one P&L" culture that enables resource sharing without geographic or profit-center barriers. Customer segments span enterprise and mid-market commercial accounts, government and public-entity clients, high-net-worth private clients, and—following the Confie merger completed November 2024—over one million personal-lines customers served through 750+ Confie retail stores.
