Corgi routes miscellaneous E&O to a 1–14 day specialty quote; THREE lists E&O within an online-quoted Business Owners Policy. ## Research Scope and Use Use this comparison to evaluate Corgi and THREE by Berkshire Hathaway for Professional Liability (E&O) Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote. ## Summary Corgi places miscellaneous E&O in a specialty quote path with a stated 1–14 day turnaround, separate from its instant-quote products. THREE lists E&O in a combined BOP and directs buyers to an online quote or Small Business Advisor.

Corgi suits technology startups wanting packages organized from pre-seed through growth, with dashboard changes as the business grows; firms seeking only a direct single-carrier policy should compare alternatives. Issuers vary by product and state.

Berkshire Hathaway Direct Insurance Company is named as issuer on THREE’s sample policy.

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [10](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [11](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [12](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [13](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance") ## Key Differences in Professional Liability (E&O) Insurance ### Quote Timing and Product Route Corgi separates miscellaneous E&O from its instant-quote Tech & AI Liability and says specialty policies take 1–14 days to quote. THREE directs small-business applicants to an online quote and says licensed Small Business Advisors can help, with E&O listed as a BOP category. If timing is central, ask Corgi for an expected turnaround on your submission and ask THREE whether E&O is part of the package being quoted. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [7](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") ### Policy Structure and Published Terms Corgi describes miscellaneous E&O as broad professional liability for service businesses but publishes no limit, retention or sample structure for this product. THREE also does not publish a separate E&O limit or deductible, instead pointing to the quote-specific summary; its E&O sits within the combined BOP. Buyers need the proposed documents from either provider to compare limits and exclusions, and should verify whether the desired line is separately selectable. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") ## What to Confirm in Professional Liability (E&O) Insurance Quotes - Ask Corgi for the expected quote date, the proposed limit and retention, and whether the policy is issued by an affiliated or third-party carrier. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [1](https://www.corgi.insure/disclaimers "Disclaimers & Licensing") - Ask THREE to show E&O as included in the BOP quote and provide its limit and deductible. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") - Compare the exclusions and covered professional services in each offered form; Corgi's public summary is broad, while THREE cautions that its sample is illustrative. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") ## Offering Details | Criteria | Corgi Miscellaneous E&O | THREE Business Owners Policy | | --- | --- | --- | | Role in This Line | Corgi lists Miscellaneous E&O as a specialty coverage quoted with a 1-14 day turnaround, separate from its instant-quote Tech & AI Liability product and from its Real Estate E&O and Lawyer E&O products, which target specific professions. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [6](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Company-reported; scope: Homepage and startup-insurance page policy-card labeling as of 2026-09-23. No dedicated product page was found; direct URL guesses (/miscellaneous-errors-and-omissions, /misc-eo) returned 404s..) | THREE presents Errors and Omissions as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant..) | | Issuing Insurer | No page names the carrier that issues Miscellaneous E&O coverage. Corgi's general disclosures say coverage may be underwritten by affiliated carriers, including Technology Risk Retention Group, or by third-party partner carriers depending on product, jurisdiction, and risk profile, without identifying which applies to this line. [1](https://www.corgi.insure/disclaimers "Disclaimers & Licensing") (Evidence: Not publicly disclosed; scope: Disclaimers page general underwriting disclosure, checked for a line-specific statement and finding none as of 2026-09-23..) | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy..) | | Who It’s For | Corgi targets Miscellaneous E&O at service-based businesses generally, positioned as a catch-all for professional-liability exposure not covered by its technology-, real-estate-, or legal-specific E&O products. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [6](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Company-reported; scope: Catalog description; no industry, size, or state restrictions are published for this line..) | The reviewed product page does not state separate eligibility rules for Errors and Omissions; the general quote and advisor route is not proof that a particular business qualifies for it. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [7](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms..) | | Coverage Features | Corgi describes Miscellaneous E&O as broad professional liability coverage for service-based businesses facing claims of negligence, errors, or failure to perform professional services, distinct from its named Tech E&O, Real Estate E&O, and Lawyer E&O products. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [6](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Company-reported; scope: One-sentence catalog description; no policy form, insuring agreement, exclusion, or claims-made/occurrence trigger is published for this line..) | THREE's Business Owners Policy page lists Errors & Omissions among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Official THREE package marketing for Errors and Omissions. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy..) | | Limits and Retentions | No limit, retention, or illustrative policy structure is published for Miscellaneous E&O, unlike Corgi's Tech E&O and Umbrella pages, which show example limits. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [6](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Not publicly disclosed; scope: Reviewed pages as of 2026-09-23; limits would appear on an actual quote..) | The reviewed public product page does not state a separate limit or deductible for Errors and Omissions; THREE says the quote-specific insurance summary lists limits and deductibles. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible..) | | Risk Services | The reviewed pages do not describe risk-management or claims-handling services specific to Miscellaneous E&O policyholders. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [6](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Not found in reviewed sources; scope: Homepage and startup-insurance page as read on 2026-09-23; general claims-handling disclosures on the disclaimers page are not specific to this line..) | Confirm in your quote. | | How to Apply | Miscellaneous E&O sits outside Corgi's instant-quote flow; the site groups it with policies quoted in 1-14 days rather than through the self-serve online application used for its core coverages. [2](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [6](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Company-reported; scope: Homepage and startup-insurance page policy-card labeling..) | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. [7](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the route for the overall THREE product.
