## Heffernan Insurance Brokers vs StartupInsurance.ai General Liability Insurance Summary

StartupInsurance.ai offers a free policy check flagging AI-related exclusions such as form CG 40 42 that it says appeared industry-wide in January 2026. Heffernan's standard brokerage names no insurer for general liability, but its Thimble-partnered on-demand product is underwritten by Markel Insurance Company. [4](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [3](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability") [1](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [2](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

## What Are the Key Differences Between Heffernan Insurance Brokers and StartupInsurance.ai General Liability Insurance?

### Checking a Policy vs. Splitting Distribution

StartupInsurance.ai says that in January 2026 the standard general liability forms industry-wide picked up three new AI-related exclusions, and illustrates its policy-check service with an example flagging exclusion form CG 40 42. [4](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage "Wording that still says yes" section; describes an industry-wide forms change the brokerage says it checks for, not the terms of any specific StartupInsurance.ai-placed policy..)

Heffernan's pages describe a different kind of split instead of a policy audit: a standard commercial brokerage placement and a separate Thimble-partnered on-demand product bought directly online. [1](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [3](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability")

### Who Underwrites, on the Panel and Off It

StartupInsurance.ai's carrier panel names six insurers, though its reviewed pages don't say which one issues a given company's general liability policy. [4](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") Heffernan's standard brokerage also names none, but its Thimble-partnered on-demand product is specifically underwritten by Markel Insurance Company. [3](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability")

### The Free Check vs. the Fast Certificate

StartupInsurance.ai's policy check turns around a one-page summary within 48 hours of receiving a current policy and customer contract. [4](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") Heffernan's on-demand product turns around a different document instead: an ACORD certificate of insurance in under 30 seconds once the online purchase is complete. [3](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability")

### Certificate Requirements Named on Each Page

StartupInsurance.ai frames its pitch around certificate requirements like additional-insured status, primary-and-non-contributory wording and a waiver of subrogation. [4](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") Heffernan's standard brokerage page addresses the certificate need more generally, without breaking out the specific wording requirements StartupInsurance.ai names. [2](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

## What Should You Confirm in Heffernan Insurance Brokers and StartupInsurance.ai General Liability Insurance Quotes?

- Ask StartupInsurance.ai which panel carrier would actually underwrite your general liability policy. [4](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")
- Ask Heffernan whether you're being quoted through its standard brokerage or its Thimble-partnered on-demand product. [3](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability")
- If you already hold a policy, ask whether StartupInsurance.ai's free check would catch the specific AI exclusion it names. [4](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review")
- Confirm which insurer would issue your policy on Heffernan's standard brokerage path, since that one names none. [1](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage")

| Role in This Line | Heffernan lists general liability among the basic coverages it places for business clients through its standard commercial-insurance brokerage, shopping insurers rather than underwriting the policy itself. [1](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") (Evidence: Company-reported; scope: Business Insurance Brokerage page as read on 2026-09-23..)<br><br>Separately, Heffernan has partnered with Thimble Insurance Services to distribute an on-demand general liability product bought directly online, a distinct and narrower distribution model from its standard commercial brokerage placement.

The brokerage is ContractorNerd Insurance Services, LLC, which its own terms describe as an insurance agency/producer that arranges coverage and does not underwrite policies itself. [4](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [6](https://www.contractornerd.com/terms-and-conditions/ "Terms and Conditions") (Evidence: Company-reported; scope: Homepage coverage list and ContractorNerd's terms and conditions; describes the brokerage's role generally and names general liability as one of the placed lines, not a specific policy's terms..) |
| Risk Services | For standard commercial clients, Heffernan says it provides claims services, loss control, HR consulting, and risk-management and assessment services alongside placed coverages such as general liability. [1](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") (Evidence: Company-reported; scope: Business Insurance Brokerage page as read on 2026-09-23; not general liability-specific and not described for the Thimble-partnered on-demand product..) | StartupInsurance.ai offers a free policy check: send in your current policies and a customer contract, and within 48 hours you get a one-page summary of AI exclusions in your program and where your contract asks for something the policy doesn't give. [4](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage service description; a marketing offer, not a guarantee of findings for any particular general liability policy..) |
