Kinro vs 
Marsh Professional Liability (E&O) Insurance
Kinro's quote-file intake and Marsh's named industry specialists reflect different scales of E&O brokerage.
What Is Kinro Insurance?
Kinro helps U.S. small businesses identify insurance needs and shop available coverage through an agency. Buyers can start online, request a policy review, or contact the team for help. 1,2,3
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. 5,6,7,8
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. 11,12,13,14
Key Differences in Professional Liability (E&O) Insurance
Broker Scale and Named Industries
Kinro and Marsh both broker professional liability/E&O rather than underwrite it. Kinro says the product "can underwrite differently" by operation and that market fit depends on carrier appetite, naming consultants, agencies, tech services and professional firms. 4
Marsh names enterprise-scale verticals its specialists serve — including banking, insurance companies, asset managers, accountants, attorneys, architects and engineers, media, technology, and healthcare and biotechnology — and says it staffs the practice with attorneys, economists and actuaries. Kinro’s reviewed materials do not describe that specialist staffing mix. 9 4
What the Base Coverage Addresses
Kinro describes E&O as covering claims tied to alleged errors, omissions, missed deadlines or service mistakes, plus defense and claim-handling questions a general liability policy may not reach. 4 Marsh's reviewed materials add a coverage scope Kinro’s reviewed materials do not mention:
Marsh says professional liability coverage can protect a company against liability and defense costs from a claim alleging an error, omission or negligence in performing professional services, and that many policies also cover privacy violations and computer security breaches. 9Company-reported. Marsh professional liability page opening description; illustrative policy description, not a specific policy form.
How Each Broker Builds Your Submission
Kinro's reviewed materials lay out a specific quote-file intake: the services you provide, client types, revenue, contract terms, prior claims, retroactive dates, and whether you handle regulated, technical, financial or operational advice, often reviewed together with cyber, general liability and D&O. 4 Marsh's reviewed materials describe the specialist team it applies to a client's exposure but do not lay out an equivalent submission checklist. 9
What to Confirm in Professional Liability (E&O) Insurance Quotes
- Ask Kinro which carrier it would route your submission to, since market fit and underwriting depend on carrier appetite for your operation. 4
- Ask Marsh which insurer it intends to place your professional liability policy with, since its pages don't name one. 9
- Confirm whether Marsh's privacy-violation and computer-security coverage is included in your quote or requires a separate cyber policy. 9
- Neither publishes limits or retentions on the reviewed pages; get both in writing. 4 9
