Marsh vs Startupinsurance: Technology E&O Insurance

A startup with signed customer contracts can have StartupInsurance.ai, an agent, read them against the E&O wording before binding; Marsh, by contrast, pairs technology specialists with data-center insurance programs.

Areas of coverage

Marsh

  • role: Marsh treats technology errors and omissions (tech E&O) as one of its financial and professional liability specialties, with dedicated attention to the technology industry, and separately names it as a building block within its data-center insurance programs. Marsh professional liability page and data-center insurance page.company-reportedSource ↗Source ↗
  • eligibility: Marsh names technology among the specialized industries its professional liability (E&O) experts serve, alongside banking, insurance and asset management, media and healthcare. Marsh professional liability page, What We Offer section.company-reportedSource ↗
  • coverage: Marsh says off-the-shelf technology E&O policies were not built for the scale and concentration of modern data centers and can leave gaps. It designs data center programs that combine technology E&O with property, casualty and other lines. Data center insurance page, Closing the gaps in conventional coverage section; describes a gap in standard tech E&O for one customer segment (data centers), not the general product.company-reportedSource ↗
  • insurer: The reviewed pages do not name a specific technology E&O insurer. Marsh professional liability and data-center insurance pages as read on 2026-09-23.not-disclosedSource ↗Source ↗

StartupInsurance.ai

  • role: 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. 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.company-reportedSource ↗Source ↗
  • coverage: 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. 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.company-reportedSource ↗
  • coverage: 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. 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.company-reportedSource ↗
  • insurer: 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. Homepage carrier panel; the panel is program-wide, not broken out by coverage line.not-disclosedSource ↗
  • application: "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. 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.company-reportedSource ↗
  • services: 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. Homepage service description; a marketing offer describing what the review covers, not a report on any specific customer's tech E&O policy.company-reportedSource ↗

What Are the Key Differences Between Marsh and StartupInsurance.ai Tech E&O Insurance?

Large-Scale Program Design vs Startup Contract Checks

Marsh places technology E&O through professional-liability specialists and data-center programs, and says off-the-shelf tech E&O wasn't built for modern data-center scale, density and aggregation. StartupInsurance.ai says most tech E&O forms leave out the accuracy warranties and uptime promises startups accept in customer contracts, and reads those contracts against the policy before you buy. Choose Marsh if you run or build data centers or need a large custom program; choose StartupInsurance.ai if you're a startup whose MSAs promise accuracy or uptime. [6] [5] [10]

How You Buy

StartupInsurance.ai's online quote screen includes Tech Errors & Omissions as one of seven coverage boxes, for claims when your tech product or service fails. Marsh doesn't describe an online application; you work with its specialists. [9] [6]

What Should You Confirm in Marsh and StartupInsurance.ai Tech E&O Insurance Quotes?

  • Ask both which insurer will issue your policy. StartupInsurance.ai's broker of record is ContractorNerd Insurance Services, LLC. [6] [10] [3]
  • Bring your MSAs to StartupInsurance.ai, and ask Marsh how contractual uptime or accuracy promises are treated on its placement. [10] [5]
  • Ask StartupInsurance.ai whether the blanket AI exclusion it mentions on some D&O, E&O and fiduciary renewals applies to your form. [10]
  • Get limits and retentions from both; neither publishes them. [5] [10]

Marsh designs technology E&O for data centers and large professional-liability accounts, saying off-the-shelf forms weren't built for their scale. StartupInsurance.ai lets startups select Tech E&O online and checks customer contracts for accuracy warranties and uptime promises the policy won't cover.
