AIG vs THREE by Berkshire Hathaway

Key Differences Between AIG and THREE

Customer Fit and Application

Compare each provider’s stated customer focus against your business activities and stage; a published target market is not a guarantee of eligibility.

AIG’s Surplus Lines section says its commercial insurance solutions serve small, middle-market, and large enterprises. The same section separately describes Lexington Casualty as an experienced excess-and-surplus-lines casualty provider; it does not explicitly assign all three customer-size segments to Lexington Casualty. ³Company-reported. AIG’s published Surplus Lines section; customer-size statement and Lexington Casualty description are adjacent but not explicitly attributed to the same business. This does not establish a provider-wide customer focus or product-specific issuer.

THREE describes its focus as businesses and presents industries it serves. Berkshire Hathaway’s 2025 annual report says BH Direct and GUARD together primarily offer commercial insurance to small and medium-sized businesses; it separately says BH Direct underwrites through the biBERK.com and Threeinsurance.com distribution platforms. Eligibility varies by state and business. ^16,22Company-reported. THREE’s company-described business focus and industry examples, plus the 2025 report’s joint BH Direct-and-GUARD SMB statement. The report does not attribute that customer-size focus to BHDIC alone; actual eligibility varies by state and business.

These entry points show how to start; they do not confirm eligibility or that coverage has been bound. ^{4 16 16 25}

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.

THREE directs prospective customers to an online quote flow and says licensed Small Business Advisors can help them start or continue the process; the company’s FAQ also describes a phone quote and says an unfinished quote can be saved and resumed. This documents quote routes, not online purchase or binding by an individual customer. ^16,18Company-reported. U.S. business insurance quote application. Company-described online and phone process; no customer form was submitted and no binding outcome was tested.

What to Confirm in Quotes

Ask your AIG broker which operating company will issue each line and how to access policy service. Ask THREE to confirm its issuer and who handles claims and changes after purchase. Ask each provider to identify the proposed insurer, exact forms and endorsements, any intermediary or account service contact, and the steps required to bind. Compare premiums only after matching limits, retentions, exclusions, policy periods, taxes and fees.
