# Heffernan Insurance Brokers vs StartupInsurance.ai General Liability Insurance

## Research Scope and Use

Use this comparison to evaluate Heffernan Insurance Brokers and StartupInsurance.ai for General Liability Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## 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.

## What Is General Liability Insurance?

General liability covers claims that your business injured someone, damaged their property or committed a specified personal or advertising offense. It does not insure your own building or equipment. [11](https://www.iii.org/article/commercial-general-liability-insurance "Commercial general liability insurance") [12](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide")

## Key Differences in 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. [8](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. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [5](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. [8](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. [5](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. [8](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. [5](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. [8](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. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance")

## What to Confirm in General Liability Insurance Quotes

- Ask StartupInsurance.ai which panel carrier would actually underwrite your general liability policy. [8](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. [5](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. [8](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. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage")

## Offering Details

| Criteria | Heffernan General Liability Insurance | StartupInsurance.ai General Liability (GL) |
| --- | --- | --- |
| 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. [3](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. [5](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability") (Evidence: Company-reported; scope: Short-Term General Liability page as read on 2026-09-23..) | StartupInsurance.ai lists general liability among the lines its startup program places. 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. [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [9](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..) |
| Issuing Insurer | For the Thimble-partnered on-demand product, Heffernan says policies are underwritten by A-rated insurers, naming Markel Insurance Company. The reviewed pages for Heffernan's standard commercial general liability placements do not name an insurer. [5](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability") [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Company-reported; scope: Short-Term General Liability page for the named insurer; Business Insurance and Small Business pages for the standard-placement gap, as read on 2026-09-23..) | StartupInsurance.ai's carrier panel names six insurers (The Hartford, Chubb, Coalition, Tokio Marine HCC, Travelers and CNA), with ratings shown for three of them, but the reviewed pages do not say which panel carrier issues a given company's general liability policy. [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Not publicly disclosed; scope: Homepage carrier panel; the panel is program-wide and not broken out by coverage line, so the specific insurer for a general liability placement is not disclosed and varies by placement..) |
| Who It’s For | Heffernan's small-business division says it serves sole proprietors through fast-growing companies across industries including construction, food, health care, hospitality, nonprofits, real estate, technology, transportation, and vintners and growers, plus named specialty programs. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Company-reported; scope: Small Business Insurance page as read on 2026-09-23; no minimum size or exclusion was published..) | StartupInsurance.ai frames its "what cleared means" pitch around certificates of insurance naming a customer or landlord as additional insured, primary and non-contributory, with a waiver of subrogation — requirements that typically apply to general liability policies. [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage narrative section aimed at founders who need a certificate to satisfy a landlord or customer contract; does not state formal underwriting eligibility criteria (industry, revenue, headcount) for general liability..) |
| Coverage Features | Heffernan describes general liability as covering bodily injury and property damage caused by a company, whether by its people or its products. [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Company-reported; scope: Small Business Insurance page as read on 2026-09-23; the reviewed pages do not list specific exclusions or endorsements..) | 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. [8](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..) |
| Limits and Retentions | Heffernan's Thimble-partnered on-demand product advertises $1 million or $2 million general liability limits, with pricing starting at $5 for short terms. [5](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability") (Evidence: Company-reported; scope: Short-Term General Liability page as read on 2026-09-23; Thimble's own disclaimer says eligibility, pricing, and coverage vary by state, activity class, and other factors..)<br><br>For its standard commercial general liability placements, Heffernan's reviewed pages do not publish limit, retention, or premium ranges. [3](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [4](https://www.heffins.com/business-insurance/small-business/ "Small Business Insurance") (Evidence: Not publicly disclosed; scope: Business Insurance and Small Business Insurance pages as read on 2026-09-23..) | The reviewed pages do not publish sample general liability limits, sublimits or retentions; StartupInsurance.ai's public marketing pages do not show program-level numbers for this line. [8](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [7](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai") (Evidence: Not found in reviewed sources; scope: Homepage and quote-intake screen as read on 2026-09-23; limits would only surface on an actual quote..) |
| 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. [3](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. [8](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..) |
| How to Apply | The Thimble-partnered product is bought directly online with no paper forms, producing an ACORD certificate of insurance in under 30 seconds according to Heffernan's page. [5](https://www.heffins.com/short-term-general-liability/ "Short-Term General Liability") (Evidence: Company-reported; scope: Short-Term General Liability page as read on 2026-09-23..) | General Liability (GL) is one of seven coverage boxes on StartupInsurance.ai's online quote-intake screen, described there as covering "bodily injury, property damage, and advertising injury." [7](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai") (Evidence: Company-reported; scope: Initial coverage-selection screen of the quote application; does not show what follow-up underwriting questions or documentation the flow requires..) |
