What Are the Key Differences Between Harper and StartupInsurance.ai General Liability Insurance?

Checking a Policy vs. Placing One

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. ²Company-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.

Harper's page describes the opposite direction: it doesn't audit an existing policy for new exclusion wording, it takes a fresh application to multiple insurers with a specialist reviewing the business first, aimed at applicants a previous insurer already declined. ¹

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. ² Harper's outcome is similarly unnamed in advance, since it shops the application across whichever of several insurers will accept it. ¹

The Free Check vs. the Same-Day Certificate

StartupInsurance.ai's policy check turns around a one-page summary within 48 hours of receiving a current policy and customer contract. ² Harper's turnaround claim covers a different moment: a same-day certificate of insurance once a policy it placed is already in force, not a review of a policy someone already holds. ¹

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. ² Harper's page addresses the certificate itself rather than its specific wording requirements, saying only that it issues one the same day a landlord, client or venue asks. ¹
