At-Bay vs biBerk: How Do They Compare for Business Insurance?

At-Bay offers cyber, technology E&O and miscellaneous professional liability, with coverage described as underwritten by non-admitted insurers. At-Bay Insurance Services LLC is its disclosed property-and-casualty agency and surplus-lines broker. ^1,5Company-reportedUS brand and disclosed producer; company statements, not regulatory verification.

biBerk says it sells small-business insurance directly without an insurance broker. This is its company-reported channel description. Its California/Massachusetts notice names four insurers collectively as issuing most policies and lists each insurer’s licensed jurisdictions, but does not identify the insurer for a particular transaction, product, or policy or guarantee product availability in a jurisdiction. ^14,15Company-reportedCompany-reported description of biBerk’s U.S. small-business sales channel on its About page; not a claim about every transaction, product route, producer role, or policy issuer.

Large technology companies may fit At-Bay’s published Tech E&O appetite, but the quote route matters: its product page lists up to $5 billion revenue and $10 million limits, while its broker platform lists $100 million and $3 million. These are ceilings, not guaranteed offers. ²Company-reportedCurrent product-page appetite; no inference of pre-revenue, industry-specific or California eligibility.

A September 2023 Tech E&O appetite PDF still accessible on At-Bay’s site has lower revenue and limit ceilings than the current product page and lists restricted classes including autonomous AI. It should not be treated as current eligibility guidance; ask underwriting for the applicable appetite version. ^12,2Company-reportedLegacy document has inconsistent autoquote revenue figures internally. Current HTML controls description of advertised ceilings, but current class eligibility remains unresolved.

biBerk targets small businesses across varied industries and lists examples such as accounting, food service, retail, and transportation.

Businesses needing miscellaneous professional liability can ask At-Bay about primary coverage with limits up to $5 million and a tailored definition of professional services; state restrictions apply, and the product is claims-made-and-reported with a duty to defend. ⁴Company-reportedCurrent MPL page; eligibility and policy wording remain underwriting-specific.

If you need limits above primary Cyber or Tech E&O, At-Bay lists excess options for those lines; this does not establish a general commercial umbrella policy. ^3,2Company-reportedShared umbrella-excess key used only for explicitly marketed excess products.

biBerk offers cyber and data-breach protection as an add-on to General Liability, Professional Liability, or a Business Owners Policy (BOP); the page does not present this as a stand-alone product. The types of response expenses and affected-person services depend on the selected base policy and terms. ¹⁸Company-reportedEntity: biBerk brand. Product: small-business cyber add-on. Jurisdiction and availability depend on state and underwriting. Company-reported page description; the issued policy and endorsement control coverage.

Do not assume a past carrier announcement identifies today’s insurer: At-Bay’s 2023 announcement said eligible new E&S Cyber and Tech E&O would use At-Bay Specialty Insurance Company, but it does not settle a current California quote or MPL issuer. ¹¹Company-reportedHistorical announcement effective August 7, 2023; no buyer-specific policy reviewed.

Ask who will issue your MPL policy: the current product page names no insurer, and a 2023 announcement naming United Specialty Company does not establish the present carrier or California availability. ^4,13Not found in reviewed sourcesCurrent issuer not established; preserve source spelling without converting historical brand wording into a verified legal-entity record.

biBerk says the four insurers it names—Wellfleet Insurance Company, Berkshire Hathaway Direct Insurance Company, National Liability & Fire Insurance Company, and Wellfleet New York Insurance Company—collectively issue most policies sold by biBerk.

The homepage states that availability depends on state and type of insurance; this is not a claim that every applicant can complete an online purchase or bind coverage.

NerdWallet’s February 2026 biBerk review reports that, during 2022–2024, state regulators received far more complaints from biBerk commercial liability and commercial property policyholders than NerdWallet expected given biBerk’s market share; NerdWallet says biBerk received its lowest possible score for this complaint factor. This is NerdWallet’s report of company-level complaint data, not a raw count or evidence about every biBerk product, a particular policy, or the quality of claim decisions. ²⁷VerifiedNerdWallet U.S. small-business-insurance review, updated February 13, 2026 and accessed September 29, 2026.
