# At-Bay vs Corgi Professional Liability (E&O) Insurance

At-Bay sells MPL through licensed producers and a broker platform; Corgi quotes miscellaneous E&O on a 1-14 day specialty path, not its instant Tech & AI flow.

## Research Scope and Use

Use this comparison to evaluate At-Bay and Corgi 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

At-Bay miscellaneous professional liability is submitted by licensed insurance professionals or quoted on At-Bay's Broker Platform. Corgi treats miscellaneous E&O as a specialty product with a 1-14 day quote, separate from instant-quote Tech & AI Liability and from named real-estate and lawyer E&O.

## 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. [7](https://www.corgi.insure/disclaimers "Disclaimers & Licensing") [8](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [9](https://www.prnewswire.com/news-releases/corgi-insurance-launches-admitted-insurance-carrier-302860246.html "Corgi Insurance Launches Admitted Insurance Carrier") [10](https://content.naic.org/sites/default/files/publication-loc-zu-listing-companies-summary.pdf "NAIC Listing of Companies") [11](https://content.naic.org/insurance-topics/risk-retention-groups "Insurance Topics: Risk Retention Groups")

## 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](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [14](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [15](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [16](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

### Who Can Start the Quote

A buyer cannot treat these two miscellaneous E&O paths as the same checkout. At-Bay markets MPL through At-Bay Insurance Services LLC and aims the product page at licensed insurance professionals submitting business, not at a retail self-serve form. Corgi lists miscellaneous E&O as a specialty coverage with a 1-14 day turnaround, kept apart from the instant-quote Tech & AI Liability product.

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. [8](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [12](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..)

[3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")

### What That Means for the Policy Shape

At-Bay publishes MPL as a named product with a claims-made-and-reported structure and a professional-services definition written for each insured, so the quote should spell out those terms before you compare price. Corgi describes miscellaneous E&O as broad professional liability for service businesses facing negligence or failure-to-perform claims, and it keeps that form distinct from named Tech, real-estate and lawyer E&O products. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [12](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance")

### How Binding Happens

At-Bay directs MPL submissions to underwriting by email or through automatic quotes on its Broker Platform, where a broker can create a quote, customize limits and retentions, and bind. Corgi's miscellaneous E&O stays outside the self-serve instant application used for core coverages, so timing and underwriting questions belong in that 1-14 day specialty process. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [12](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance")

## What to Confirm in Professional Liability (E&O) Insurance Quotes

- Ask At-Bay whether the quote is claims-made-and-reported and how professional services are defined for your firm. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite")
- Ask Corgi whether you are on miscellaneous E&O or a named profession product, and the expected quote window. [12](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance")
- Get the issuing insurer from both; neither reviewed page is a substitute for the binder. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [12](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance")

## Offering Details

| Criteria | At-Bay Miscellaneous Professional Liability (MPL) Insurance | Corgi Miscellaneous E&O |
| --- | --- | --- |
| Role in This Line | At-Bay markets MPL as one of its own named insurance products, sold through its disclosed producer, At-Bay Insurance Services LLC, with the product page directed at "properly licensed insurance professionals" submitting business rather than at direct retail buyers. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [4](https://www.at-bay.com/licenses/ "Licenses") (Evidence: Company-reported; scope: Current MPL product page and license disclosures; this describes the distribution channel, not who bears the underwriting risk..) | 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. [8](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [12](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..) |
| Issuing Insurer | The current MPL product page does not name the insurer that issues the policy. A September 2023 press release named United Specialty Company in connection with MPL, but that historical reference does not establish the current issuing insurer for a new MPL quote. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [5](https://www.at-bay.com/press_releases/at-bay-doubles-mpl/ "At-Bay Doubles Miscellaneous Professional Liability Appetite") (Evidence: Not found in reviewed sources; scope: Reviewed MPL page as of 2026-09-23 and the September 2023 press release; restates the existing provider fact that MPL's current issuer is unresolved, distinct from the August 2023 Cyber/Tech E&O transition to At-Bay Specialty Insurance Company paper..) | 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. [7](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..) |
| Who It’s For | At-Bay says it provides primary MPL for businesses of all revenue sizes with limits up to $5 million, subject to state restrictions and eligibility requirements detailed in a separate MPL appetite guide. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Current MPL appetite paragraph; the linked appetite guide's specific eligibility requirements were not independently opened for this record..) | 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. [8](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [12](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..) |
| Coverage Features | At-Bay lists MPL coverage highlights including automatic coverage for acquired subsidiaries, claims-made-and-reported coverage, coverage for independent contractors, disciplinary-proceedings defense, a duty-to-defend contract, personal-injury coverage (including emotional distress), punitive damages where insurable, a professional-services definition written for each insured, and an 80/20 hammer clause. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Product-page coverage-highlights list; an 80/20 hammer clause is a settlement provision where the insurer pays 80% and the insured pays 20% of costs after the insured declines a recommended settlement. The issued policy and declarations control actual wording, limits and exclusions..) | 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. [8](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [12](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..) |
| Limits and Retentions | At-Bay publishes an MPL limit ceiling of up to $5 million, with state restrictions that are not detailed on the product page itself. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") (Evidence: Company-reported; scope: Current appetite paragraph; this is an advertised ceiling, not a guaranteed available limit for any specific applicant..) | 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. [8](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [12](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..) |
| Risk Services | Not described in the reviewed sources. | The reviewed pages do not describe risk-management or claims-handling services specific to Miscellaneous E&O policyholders. [8](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [12](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..) |
| How to Apply | At-Bay directs MPL submissions to underwriting by email or through automatic quotes on its Broker Platform, which At-Bay describes as a workflow of creating a quote, customizing limits and retentions, and binding the policy. [3](https://www.at-bay.com/insurance/mpl/ "MPL Insurance: Coverage Highlights & Appetite") [6](https://www.at-bay.com/brokers/platform/ "Broker Platform") (Evidence: Company-reported; scope: Current submission instructions and the general broker-platform workflow description; MPL-specific automation details were not separately confirmed..) | 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. [8](https://www.corgi.insure "Corgi Insurance: Startup Insurance, Quoted in Minutes") [12](https://www.corgi.insure/startup-insurance "Startup Insurance | Corgi Insurance") (Evidence: Company-reported; scope: Homepage and startup-insurance page policy-card labeling..) |
