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 Alliance Risk?
Alliance Risk suits tech startups from pre-seed through IPO that want a broker to review their tech E&O policy for free and shop specialist insurers; if you want to buy online in minutes, use a digital insurer. Quotes take 24 hours to ten business days, depending on your risk. 4,5,6
What Is Commercial Property Insurance?
Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. 8,9,10
Key Differences in Commercial Property Insurance
Insurer-led property products and broker-arranged placements
AIG markets commercial property insurance, including Retail Property, and says its options serve organizations such as hospitals, universities, and global manufacturers. Alliance Risk places property coverage for commercial landlords, tenants with valuable equipment or inventory, retail, restaurants, warehouses, offices, and manufacturers. AIG describes the insurance product; Alliance Risk describes access to insurer markets and placement advice. Ask Alliance Risk which carrier would bear the risk, and AIG which issuing company appears on its quote. 3 7
Risk engineering and loss recovery
AIG says property risk engineers work with clients to identify and mitigate loss, while a dedicated Property claims team handles claims; the page does not promise a service deadline. Alliance Risk describes reviewing property and business-interruption valuations and says its claims advocates negotiate with underwriters and adjusters. Those services occur at different points in the relationship: ask AIG about account-level engineering access and Alliance Risk about its role when a claim is disputed. 3 7

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]

AIG vs Alliance Risk: Commercial Property Insurance: documented features by provider
| Criteria | AIG Commercial Property and Retail Property | Alliance Risk Property Insurance |
|---|---|---|
| Role in This Line | AIG markets commercial property insurance and identifies Retail Property as a product area. For domestic and global corporate and risk-management clients, the page describes both risk-transfer insurance and non-risk-transfer fronting or captive solutions; those structures are not the same as an insurance policy issued by AIG. 3Company-reported. AIG’s U.S. Commercial Property page. It does not identify the insurer or fronting company for a particular buyer’s placement. | Alliance Risk places commercial property insurance for businesses that own or lease buildings, equipment or inventory, describing its role as market access, risk assessment and claims advocacy rather than underwriting the policy itself. 7Company-reported. Property Insurance page; Alliance Risk is a broker and does not issue the policy. |
| Issuing Insurer | Confirm in your quote. | The property page does not name the insurers Alliance Risk places commercial property coverage with; it says only that it secures "competitive terms from top insurers." 7Not publicly disclosed. Property Insurance page as read on 2026-09-23; the issuing insurer depends on the specific placement. |
| Who It’s For | AIG names businesses including hospitals, universities and global manufacturing among the varied organizations for which it has property options.

Property Insurance page, "Who Needs Property Insurance?" section. |
| Coverage Features | AIG describes commercial property insurance as protecting business physical property against unexpected events such as storm damage, theft and vandalism, and says coverage can extend to certain work-related contents such as office equipment, furniture, fixtures and inventory. These are examples; actual coverage depends on the facts and each policy’s terms, conditions and exclusions. 3Company-reported. General property description on AIG’s product page, not a summary of a specific policy or all covered causes of loss. | Alliance Risk describes property coverage for buildings, business personal property, equipment and interior improvements against fire, theft, windstorm and explosion, and separately notes that earthquake, flood, employee theft and lost income are excluded and need separate policies. 7Company-reported. Property Insurance page, "What Does/Doesn't Property Insurance Cover?" sections; the issued policy and declarations control actual terms. |
| Limits and Retentions | The reviewed page does not state standard property limits, deductibles or retentions for a buyer. Confirm those amounts, covered causes and conditions in the quote and issued policy. 3Not publicly disclosed. AIG’s U.S. Commercial Property marketing page reviewed 2026-09-30; no buyer-specific quote or policy form was reviewed. | Alliance Risk's property page gives indicative annual cost ranges by property class (for example $750–$2,500 for retail or small office risks up to $30,000–$100,000+ for high-value portfolios) but does not publish standard coverage limits, sublimits or deductibles for a placement. 7Not publicly disclosed. Property Insurance page, "How Much Does Property Insurance Cost?" section as read on 2026-09-23; actual limits and retentions appear on a quote and declarations. |
| Risk Services | AIG says property risk engineers help clients identify and mitigate loss and that its engineers collaborate with clients on solutions tailored to risk factors.

Property Insurance page, "Our Approach to Property" and "The Alliance Risk Difference" sections. |
| How to Apply | Confirm in your quote. | The property page repeats a general "Get a Quote" call to action but does not describe a property-specific document checklist, unlike Alliance Risk's technology E&O page, which lists exact submission items. 7Not found in reviewed sources. Property Insurance page as read on 2026-09-23. |
| Claims Support | AIG describes a dedicated Property claims team and a claims promise intended to enable prompt resolution. The page does not publish a service-level deadline or claim outcome guarantee. 3Company-reported. AIG’s company-reported general property claims description; no account-specific claims handling terms were reviewed. | Alliance Risk says its property claims advocacy negotiates with underwriters and adjusters to "maximize your recovery" after a loss, as part of its stated approach to this line. 7Company-reported.
