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. 8Company-reported. 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 5
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 Heffernan's standard brokerage also names none, but its Thimble-partnered on-demand product is specifically underwritten by Markel Insurance Company. 5
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 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
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 Heffernan's standard brokerage page addresses the certificate need more generally, without breaking out the specific wording requirements StartupInsurance.ai names. 4
What to Confirm in General Liability Insurance Quotes
- Ask StartupInsurance.ai which panel carrier would actually underwrite your general liability policy. 8
- Ask Heffernan whether you're being quoted through its standard brokerage or its Thimble-partnered on-demand product. 5
- If you already hold a policy, ask whether StartupInsurance.ai's free check would catch the specific AI exclusion it names. 8
- Confirm which insurer would issue your policy on Heffernan's standard brokerage path, since that one names none. 3

| Criteria | Heffernan General Liability Insurance | StartupInsurance.ai General Liability (GL) |

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. |

For its standard commercial general liability placements, Heffernan's reviewed pages do not publish limit, retention, or premium ranges. 3,4Not publicly disclosed. 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. 8,7Not found in reviewed sources. 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. 3Company-reported. 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. 8Company-reported. Homepage service description; a marketing offer, not a guarantee of findings for any particular general liability policy. |
