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. 4Company-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. 1 3
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 Heffernan's standard brokerage also names none, but its Thimble-partnered on-demand product is specifically underwritten by Markel Insurance Company. 3
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 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
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 Heffernan's standard brokerage page addresses the certificate need more generally, without breaking out the specific wording requirements StartupInsurance.ai names. 2
