AIG vs Marsh

AIG’s commercial policies are issued by subsidiaries or affiliates, while Marsh describes broking coverage for clients and advising on insurer selection. Marsh’s U.S. segments distinguish midsize, middle-market and larger complex accounts, making this comparison useful when choosing the placement and advisory route for a growing company. 1,4,33,16,30

Current Spot Scores

Each score uses the rubric for that provider’s documented role. Providers with more than one role may have a score for each.

Marsh

Broker

Broker

5.6/ 10

Assessed provider: Marsh. Scope: US Marsh brokerage legal entities evidenced in the current Marsh client compensation guide, together with the Marsh Risk business and its International Placement and Bermuda arm as Marsh presents them in its own facility announcements for US-based buyers. Marsh USA LLC's separate Amazon affinity-programme role and its dated producer disclosure are scoped only to that programme. Producer authority is independently verified for Marsh USA LLC in Georgia, Texas, Pennsylvania, Colorado, Nevada, Indiana and Minnesota only; every other jurisdiction remains company-reported. The assessed activity is insurance brokerage, client advisory, claims advocacy and the facility-level carrier and capacity arrangements Marsh publishes for US placements; Marsh McLennan Agency, Victor, insurers, reinsurers and non-US affiliates are excluded from scored scope, and the issuing insurer for an individual buyer's placement is not assessed.

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]

Key Differences

Marsh describes a Corporate segment for midsize domestic companies, Marsh McLennan Agency for middle-market businesses, and Risk Management for large, complex programs. AIG’s Surplus Lines overview references small, middle-market and large enterprise solutions, but does not make one product or issuer universal. Ask which Marsh team and AIG product channel fit the account before comparing proposals. 1 2 33 32 17 1 2 3 16 18 33 35

Marsh describes a consultative placement relationship and a public contact path; AIG lists broker and agent portal tools rather than a public direct-buy flow. Agree on the producer of record, markets to be approached and the information each underwriter needs. 4 30 31 36

Marsh describes client-advisory and analytics services alongside brokerage, while AIG lists broker access to documents and loss runs. Ask which services are included in the Marsh engagement and which AIG servicing tasks remain with your broker or insurer. 4 5 33 32 38 41 42 17

AIG’s disclosure describes commissions and possible contingent payments to brokers and agents; Marsh’s cited information addresses a different part of the placement or its fees. These amounts are not a buyer price estimate. Ask separately for the policy premium, compensation paid to each producer and any buyer-paid fee. 6 33 32 45

What to Confirm in Quotes

  • Which Marsh business segment and legal producer would service the account, and which AIG subsidiary would issue each policy? 1 2 33 32 17
  • Will Marsh seek an AIG quote alongside other insurers, and how will it document the options considered? 4 30 31 36
  • Request all account-specific commissions, fees and contingent or supplemental compensation, then compare the service scope and renewal timetable. 4 5 33 32 38 41 42 17 6 33 32 45

CriteriaAIGMarsh
Business role

“AIG” is the marketing name for American International Group, Inc.'s worldwide operations. AIG says insurance products are written or provided by subsidiaries or affiliates; its U.S. legal notice lists multiple U.S.-domiciled property and casualty insurers but does not identify which company would issue a particular commercial policy. 1,2Company-reported. AIG group naming and the listed U.S.-domiciled property and casualty companies. The legal notice is not a policy-specific carrier assignment or complete ownership chart.

Marsh’s US compensation guide states that, as an insurance broker, Marsh’s role is to facilitate placement of insurance coverage on behalf of clients. The transparency page describes determining appropriate insurers and negotiating with those insurers. Marsh is not identified in these sources as the insurer that issues or pays the policy. 33,32,17Company-reported. US client-compensation and transparency disclosures. Affinity/Amazon administrator language is a separate program role and is not treated as the default retail relationship.

Current Marsh materials use more than one US legal name. The compensation guide (copyright 2024, Marsh LLC) refers to Marsh LLC and Marsh USA LLC entering client agreements. The transparency page instead names Marsh LLC and Marsh USA Inc. Marsh McLennan Agency is described as a wholly owned Marsh subsidiary. A 2006 California decision caption used MARSH USA, INC., dba MARSH RISK AND INSURANCE SERVICES, license 0437153. Confirm the exact contracting producer on the proposal and license documents; current California license status remains unverified. 33,32,34,35,16,46Conflicting sources. Unresolved Inc. versus LLC naming. Affinity’s Marsh USA LLC license table is company-reported as of 8 March 2024 and is not a CDI live lookup. Brand unification in January 2026 is described as a brand change, not a change in business structure.

Application process

AIG lists a North America myAIG portal for brokers and agents to access loss runs, policy documents, applications, and tools, and a separate U.S. portal for producer appointment requests. The public pages do not establish that a business can complete an online purchase or bind coverage directly. 4Company-reported. Publicly listed North America broker/agent portal functions and U.S. producer appointment requests. Authenticated workflow and product-specific submission or binding steps were not reviewed.

The public Marsh path to speak with a broker is an inquiry, not an online bind. Contact pages ask you to choose an inquiry type, including a sales or RFP route. The business-inquiry page says to complete a form and that a representative will respond within 48 hours; it points existing-policy certificate, billing and policy questions elsewhere. The inquiry page does not display premiums or bind coverage. The 48-hour response time is a company statement, not a binding or service guarantee. 30,31,36Company-reported. Inspected public contact-select and business-form pages on 16 September 2026 without submitting information. MMA has a separate contact page. Inquiry is not a completed insurance application.

Marsh describes a broker-led placement: identifying insurers for the risk, negotiating coverage and price, and, in core US broking segments, disclosing quotes and premium indications received. It may share incumbent or competing insurer names, pricing objectives, expiring terms, or give an insurer a last look when it believes that is in the client’s interest or the client instructs it. Those market practices are disclosure statements, not a guaranteed outcome or turnaround. 33,32Company-reported. Compensation guide transparency pledges and market-activity list. Not observed live placements.

Servicing and renewals

AIG lists its North America broker portal as a place for brokers and agents to access loss runs, policy documents, applications, and tools. The page does not explain how renewals are managed or promise renewal terms or timing. 4Company-reported. Public description of a North America broker/agent portal; authenticated functions and account-specific availability were not reviewed.

Marsh markets ongoing consulting, analytics and client-advisory services alongside brokerage, including Marsh Risk Consulting, risk analytics and captive solutions named in the compensation guide. MMA describes risk-control, benchmarking and claims management as part of casualty and property service. Core US broking segments pledge to disclose quotes automatically; other segments do so upon request. Public pages do not document a self-serve policy portal comparable to an online-only insurer, and they do not publish a universal renewal timetable. 33,32,38,41,42,17Company-reported. Service descriptions, not observed client-portal access. MarketConnect tools that share upcoming-renewal information with insurers are insurer-consulting products, not a buyer portal.

Fees and compensation

AIG says its companies compensate brokers and independent agents with commissions set at policy purchase, renewal, placement, or servicing, and may also pay contingent compensation. Specific compensation varies; the disclosure directs buyers to their broker or agent for policy-specific information. 6Company-reported. AIG's disclosure for business placed by brokers and independent agents with U.S. AIG offices issuing policies in the United States and territories for specified lines; its ranges describe business written in 2024 and exclude stated categories. Not a statement of any buyer's commission or total insurance cost.

Marsh’s US compensation guide says it may be paid by insurer retail commissions, client fees (often in a written Client Service Agreement, sometimes crediting commissions), wholesale commissions, insurer consulting compensation, supplemental commissions, compensation for facilities or other insurer arrangements, interest on premium accounts, and other benefits. Marsh says it does not accept contingent commissions on domestic placements for US clients in core broking operations, except for employee health and benefits or when acting as managing general agent or underwriting manager; Marsh McLennan Agency does accept contingent commissions. Standard public premium ranges or a startup fee schedule were not found. Request an account-specific disclosure of commissions, fees, contingent or supplemental amounts, premium finance charges and any affiliated-market compensation. 33,32,45Company-reported. US compensation guide as of the 2024 copyright PDF retrieved 16 September 2026. MMA’s 2026 guide landing page was reviewed; the MMA PDF itself was not fully extracted. Absence of a public price is not zero cost.
