## Research Scope and Use

Use this comparison to evaluate At-Bay and StartupInsurance.ai for Tech 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 describes its Tech E&O policy, Stance and published limits. StartupInsurance.ai lists Tech E&O as a program line arranged by ContractorNerd Insurance Services, LLC, and says it checks customer contracts for accuracy warranties and uptime promises the policy may not cover.

## What Is Technology Errors and Omissions (E&O) Insurance?

Technology errors and omissions (E&O) insurance addresses claims that a technology product or service caused a customer or other third party a financial loss. It doesn't extend to cyber incidents, bodily injury or professional services outside the quoted product. [11](https://doas.ga.gov/sites/default/files/2025-08/SPD-SP048%20Insurance%20and%20Bonding%20Guidelines%20August%202025.pdf "Insurance and Bonding Guidelines") [12](https://www.thehartford.com/professional-liability-insurance/errors-omissions-insurance/technology "Technology Errors and Omissions Insurance") [13](https://www.chubb.com/content/dam/chubb-sites/chubb-com/us-en/business-insurance/digitech-enterprise-risk-management-digitech-erm/documents/pdf/17010186-digitech-erm-12.17.pdf "DigiTech Enterprise Risk Management")

## Key Differences in Tech E&O Insurance

### Who Places the Risk

At-Bay places Tech E&O through its producer and describes the policy terms it sells. ai lists “Tech E&O and Professional Liability” as a program line, and ContractorNerd Insurance Services, LLC arranges it as agent/broker of record rather than underwriting it. [4](https://www.at-bay.com/licenses/ "Licenses") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [9](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [10](https://www.contractornerd.com/terms-and-conditions/ "Terms and Conditions")

### Contract Warranty Gaps Versus Form Highlights

ai says most tech E&O forms leave out coverage for accuracy warranties and uptime promises a startup takes on in customer contracts, and that it reads those contracts against the policy before binding (its free policy check). [9](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights")

## Offering Details

| Criteria | At-Bay Tech E&O Insurance | StartupInsurance.ai Technology Errors & Omissions (Tech E&O) Insurance |
| --- | --- | --- |
| Role in This Line | At-Bay places Tech E&O insurance through its disclosed producer, At-Bay Insurance Services LLC, which is licensed as an insurance producer in all 50 states. At-Bay says eligible new excess-and-surplus (E&S) Tech E&O business has been written on its own carrier paper, At-Bay Specialty Insurance Company, since August 2023. [4](https://www.at-bay.com/licenses/ "Licenses") [5](https://www.at-bay.com/press_releases/at-bay-begins-issuing-policies-on-its-own-paper/ "At-Bay Begins Issuing Policies on its own E&S Paper") (Evidence: Company-reported; scope: Producer role from the current license page; carrier role from a 2023 transition announcement covering Cyber and Tech E&O together, not confirmed for every current quote..) | StartupInsurance.ai's coverage list places "Tech E&O and Professional Liability" as one program line, and ContractorNerd Insurance Services, LLC arranges it as agent/broker of record rather than underwriting it. [9](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") [10](https://www.contractornerd.com/terms-and-conditions/ "Terms and Conditions") (Evidence: Company-reported; scope: Homepage coverage list and ContractorNerd's terms and conditions on its producer role; the page bundles tech E&O with professional liability in this one catalogue entry rather than describing them separately..) |
| Issuing Insurer | The current Tech E&O product page does not name an issuing insurer. At-Bay's 2023 announcement says new E&S Tech E&O business is quoted on At-Bay Specialty Insurance Company paper, but that is a historical statement, not a per-quote disclosure. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") [5](https://www.at-bay.com/press_releases/at-bay-begins-issuing-policies-on-its-own-paper/ "At-Bay Begins Issuing Policies on its own E&S Paper") (Evidence: Company-reported; scope: Tech E&O product page checked today names no insurer; the carrier-transition release is dated August 2023 and does not cover every current state or account..) | The homepage's carrier panel does not identify which panel carrier underwrites tech E&O placements; the reviewed pages do not disclose a specific insurer for this line. [9](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Not publicly disclosed; scope: Homepage carrier panel; the panel is program-wide, not broken out by coverage line..) |
| Coverage Features | At-Bay says its Tech E&O policy expands breach-of-contract coverage beyond a standard technology liability policy, carries no exclusion for breach of warranties, guarantees or consequential damages, and extends intellectual-property infringement coverage to trade-secret misappropriation, cybersquatting, improper deep-linking and source-code license violations, in addition to standard software copyright infringement. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Product-page coverage highlights; the issued policy and endorsements control actual terms..)<br><br>At-Bay describes negligence coverage for improper installations, coding errors, data-processing flaws, failed implementations and network outages, plus contractual-indemnity coverage for obligations a technology company owes customers from an alleged wrongful act. It also counts service credits issued to settle a claim as payable damages under the policy. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Product-page coverage highlights; the issued policy and endorsements control actual terms..) | StartupInsurance.ai says most tech E&O forms leave out coverage for accuracy warranties and uptime promises that a startup takes on by signing a customer contract, and that it reads customer contracts against the tech E&O policy before binding to catch that gap. [9](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage "wording that still says yes" section; describes a general gap the brokerage says it looks for, not the terms of a specific StartupInsurance.ai-placed tech E&O policy..)<br><br>StartupInsurance.ai says one major carrier added a blanket AI exclusion to "D&O, E&O and fiduciary" forms at renewal; the page does not specify whether "E&O" here means technology E&O, professional E&O, or both. [9](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage "wording that still says yes" section; the E&O reference is ambiguous between the two E&O lines the program sells, so this claim is not conclusively tech-E&O-specific..) |
| Limits and Retentions | At-Bay says it writes primary and excess Tech E&O insurance for businesses with revenue up to $5 billion and limits up to $10 million. Through its Broker Platform, brokers can get automated quotes only for businesses up to $100 million in revenue and $3 million in limits. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Published appetite ceilings, not guaranteed offers; underwriting and the appetite guide control individual accounts..) | Not described in the reviewed sources. |
| Risk Services | Every At-Bay Tech E&O policy includes access to At-Bay Stance, a security platform with vulnerability monitoring, vCISO advisory and tabletop exercises, and security awareness training, the same InsurSec package structure marketed with its cyber product. Managed detection and response (MDR) is a separate purchase sold by At-Bay Security, LLC. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Product-page InsurSec and footnote descriptions; MDR pricing is described as estimated and subject to change..) | StartupInsurance.ai's free policy check reads a startup's customer contracts against its tech E&O wording, flagging places where the contract promises something (like an accuracy warranty) the policy doesn't cover. [9](https://www.startupinsurance.ai/ "Startup Insurance | Coverage that clears the review") (Evidence: Company-reported; scope: Homepage service description; a marketing offer describing what the review covers, not a report on any specific customer's tech E&O policy..) |
| How to Apply | You apply for At-Bay Tech E&O coverage by emailing a submission to underwriting@at-bay.com or by requesting an automated quote through At-Bay's Broker Platform. [3](https://www.at-bay.com/insurance/tech-eo/ "Tech E&O Insurance Coverage and Policy Highlights") (Evidence: Company-reported; scope: Product-page submission instructions; the Broker Platform route is limited to accounts within its lower appetite ceilings..) | "Tech Errors & Omissions" is one of seven boxes on StartupInsurance.ai's online quote-intake screen, described there as coverage for "claims from your tech products or services failing." The same screen shows no separate box for general professional liability. [8](https://quotes.startupinsurance.ai/ "Apply for Startup Insurance | StartupInsurance.ai") (Evidence: Company-reported; scope: Initial coverage-selection screen of the quote application; the absence of a distinct professional-liability box shows how the flow packages this line, not that professional liability is unavailable..) |
| Claims Support | At-Bay's claims-handling page describes a cyber incident roadmap and breach-coach hotline for ransomware and system-interruption events, but the reviewed page does not describe a separate process for a Tech E&O claim that does not involve a cyber incident, such as a professional-liability or contract dispute. [6](https://www.at-bay.com/claims/ "Claims Handling") (Evidence: Not found in reviewed sources; scope: Claims-handling page as read on 2026-09-23; does not establish that no Tech E&O-specific process exists, only that this page does not describe one..) | Not described in the reviewed sources. |
