CPA firms are the audience for USI Insurance Services, which runs the CNA-underwritten AICPA program for sole practitioners and regional firms. Founder Shield, a brokerage, serves venture firms, SaaS marketplaces and software developers. USI's AICPA program serves CPA firms; Founder Shield targets venture-backed and technology businesses and often packages E&O with cyber. ## Founder Shield vs USI Insurance Services Professional Liability (E&O) Insurance Summary USI says the AICPA Professional Liability Program it runs for CPA firms is underwritten by CNA, while Founder Shield's E&O page names no specific insurer and instead commits to carriers rated A- or better by AM Best. [4](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") [3](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?") ## What Are the Key Differences Between Founder Shield and USI Insurance Services Professional Liability (E&O) Insurance? ### A Named Insurer Versus a Rating Standard USI names the specific underwriter behind the professional liability program it runs for CPA firms: USI's own page states that the AICPA Professional Liability Program is "underwritten by CNA," naming the carrier for that specific program. USI's general Business Services E&O placements do not name an insurer. [4](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Company-reported; scope: Direct quote from the AICPA program page; CNA underwrites only this named program, not USI's other professional-liability placements..) Founder Shield does not name an insurer for its E&O line; it instead commits to placing policies only with carriers rated A- or better by AM Best, chosen for the client's industry. [3](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?") ### Profession-Specific Program Versus Broader Client List USI markets its named program specifically to sole practitioners and regional CPA firms, and has been the endorsed AICPA Program provider since 1994. [4](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") Founder Shield instead names a wider range of client types for its E&O line: venture capital firms, consultants, media and advertising agencies, SaaS marketplaces, and software developers who perform services for others. [1](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance") ### Services Bundled With Coverage USI says CPA firms enrolled in its program get supportive claims handling and exclusive access to risk-management resources, including engagement-letter templates, in addition to the coverage itself. [4](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") Founder Shield's E&O page does not describe a comparable risk-management service; it lists coverage for defense costs, regulatory-proceeding defense, lost earnings and employee or contractor error claims. [1](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance") ## What Should You Confirm in Founder Shield and USI Insurance Services Professional Liability (E&O) Insurance Quotes? - If your business is not a CPA firm, ask USI whether its general Business Services practice, rather than the named AICPA program, would place your E&O. [4](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") - Ask Founder Shield to name its A- or better AM Best-rated carrier for your placement, since its page states a rating floor rather than a carrier. [3](https://foundershield.com/insurance-faqs/general-faqs/how-do-you-decide-which-carriers-to-approach/ "How Do You Decide Which Carriers to Approach?") - Ask USI for the specific limit, retention and premium for your firm, since the AICPA program page does not publish figures. [4](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") - Neither Founder Shield's page publishes limit figures for E&O; request specific amounts directly.

[1](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance") (Evidence: Company-reported; scope: Product page; the issued policy and declarations control actual coverage..) | USI describes the policy as insuring a CPA and their practice against third-party claims that professional services caused financial harm, providing a defense and paying damages for covered claims arising from high-risk situations tied to new clients, changing business plans, or new laws and regulations. [4](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") (Evidence: Company-reported; scope: Program page description; actual insuring agreements, exclusions and conditions are set by the issued CNA policy form..) | | Role in This Line | Founder Shield is a retail insurance brokerage, described on its site as “the innovation arm of The Baldwin Group,” and places Founder Shield Errors & Omissions Insurance with third-party carriers rather than underwriting the policy itself.

Founder Shield says E&O (professional liability) is often packaged with technology E&O and cyber coverage since the two types of claims tend to intertwine. [1](https://foundershield.com/coverage/errors-and-omissions-insurance/ "Errors & Omissions Insurance") (Evidence: Company-reported; scope: Errors & Omissions Insurance product page..) | For CPA firms, USI runs the AICPA Professional Liability Program through its USI Affinity division as the endorsed producer, rather than underwriting the policy itself.
