AIG vs 
Marsh: How Do They Compare for Workers’ Compensation Insurance?
What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2
What Is Marsh?
Marsh suits technology and larger businesses seeking specialist cyber placement or broad global risk advice; small firms wanting a quick standard quote should compare its MMA route or digital agencies. 5,6,7,8
What Is Workers’ Compensation Insurance?
Workers’ compensation can pay medical care and part of an employee’s lost wages after a work-related injury or illness. If you have staff, check who is covered in each state; owners, contractors and some workers may be treated differently. 10,11,12,13
Key Differences in Workers’ Compensation Insurance
Carrier program and advisor-led access
AIG includes workers’ compensation in corporate casualty and describes customized retained-risk structures. Marsh McLennan Agency places the line within a broader casualty practice and directs buyers to a casualty specialist rather than an online quote. Ask MMA which markets it will approach and AIG which program and retained-risk design can consider your organization. 3 9
Analytics and claims support
Marsh McLennan Agency describes risk consulting, claims management using data analytics, and risk analytics across its casualty program. AIG describes risk experts, claims specialists, and litigation-management strategies. Ask what analysis and claims support each team assigns to the account, then review the issuing carrier’s policy terms separately. 3 9

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.[1][2]

Marsh’s global Trustpilot profile has a poor 1.3/5 score. Treat it as a service warning to investigate with your proposed team; it does not isolate US commercial accounts.[2][4][7]
