Corgi vs 
Marsh Professional Liability (E&O) Insurance
Marsh names a specialist team of attorneys, economists and actuaries for professional liability; Corgi's Miscellaneous E&O page describes no comparable service.
What Is Corgi Insurance?
Corgi Insurance sells commercial coverage to technology startups through stage-based packages (pre-seed and seed, Series A, and growth stage) that combine general liability, directors and officers, technology E&O, cyber, and related lines, alongside a growing small-business product line for other industries. Coverage may be issued by Corgi’s own risk retention group, an affiliated admitted carrier, or a partner insurer, so the issuing entity and available protections depend on the specific product and state. 1,2,3,4,5
What Is Marsh?
Marsh is a global insurance broker and risk advisor. In the United States it places coverage through core Marsh teams and through Marsh McLennan Agency for many middle-market buyers, including technology, cyber, property, casualty and benefits programs. 7,8,9,10
What Is Professional Errors and Omissions (E&O) Insurance?
Professional errors and omissions (E&O) insurance, also called professional liability insurance, addresses claims that professional services or advice caused a client financial loss. What's covered depends on the services actually scheduled in the policy, not the product label alone. 13,14,15,16
Key Differences in Professional Liability (E&O) Insurance
A Named Specialist Team, or No Service Description at All
Marsh says it employs attorneys, economists and actuaries alongside coverage specialists to assess a client's professional liability exposure from multiple angles, given the complexity of these risks:
Marsh says it employs attorneys, economists and actuaries alongside coverage specialists to assess a client's professional liability exposure from multiple angles, given the complexity of these risks. 11Company-reported. Marsh professional liability page.
Corgi's Miscellaneous E&O listing describes no comparable advisory or risk-assessment service; the reviewed pages present it as a self-contained product card. 6
Named Industry Specialties Versus a General Catch-All
Marsh names industries its professional liability experts serve, including banking and broker/dealers, insurance companies and asset managers, venture capital, accountants, attorneys, architects and engineers, media and entertainment, technology, and healthcare and biotechnology. 11 Corgi instead markets Miscellaneous E&O broadly to service-based businesses, separated from its own named Tech E&O, Real Estate E&O and Lawyer E&O products rather than broken out by specialized industry. 6
What the Base Policy Can Include
Marsh says professional liability coverage protects against liability and defense costs from an error, omission or negligence claim, and that many policies also cover privacy violations and computer security breaches. 11 Corgi describes Miscellaneous E&O as covering negligence, errors, or failure to perform professional services, without addressing privacy or computer-security exposure in the reviewed pages. 6
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask Marsh which specialists (attorney, economist, actuary) actually reviewed your exposure, and what that review changed about the placement. 11
- Ask Corgi whether Miscellaneous E&O includes any privacy or computer-security coverage, since the reviewed pages don't address it either way. 6
- Get the issuing insurer from both; neither reviewed page names one for this line. 11 1
- Request published limit and retention figures from both, since neither shows them. 11 6
