Introduction
biBerk describes direct online insurance for small businesses across lines such as BOP, general liability, workers’ compensation, commercial auto and professional liability. Cowbell’s published programs center on cyber coverage for small and midsize businesses, with separate options for technology E&O and cyber excess. If your priority is a direct route to common business lines, biBerk describes that path; if cyber limits, technology E&O or security services are central, ask a Cowbell-appointed agent which program is available for your risk. 3 23 30
Cowbell distinguishes admitted Prime 100 options from surplus-lines Prime 250, Prime One and excess products, with different revenue fit, limits and state availability. Do not use the broad program catalogue to infer that a specific business qualifies or that its limits can be combined; match the quote to its product and jurisdiction. 25 27 28

| Criteria | biBerk | Cowbell |
|---|---|---|
| Business role | 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. 1,2Company-reported. Company-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. | Your policy’s named insurer remains responsible for coverage; Cowbell is an insurance platform and agency that may act as a general agent. Cowbell Insurance Agency LLC identifies itself as a US P&C producer. 15,19,16Company-reported. Cowbell's current U.S. website and producer disclosure; the exact role can vary by product and placement. Cowbell identifies Zurich as a $60 million Series C investor and partner, while Zurich describes Cowbell as its technology collaborator for Select Plus. The reviewed sources do not describe Cowbell as a Zurich subsidiary or say that Zurich underwrites every Cowbell product. 18,33,17Company-reported. Ownership and commercial relationship characterization in Cowbell's 26 July 2024 financing announcement and current Zurich Select Plus page; no capitalization table was available. |
| Customer focus | biBerk targets small businesses across varied industries and lists examples such as accounting, food service, retail, and transportation. The homepage FAQ says availability depends on the state and type of insurance; the industry list is illustrative, not an eligibility guarantee. 3,1Company-reported. U.S. small-business audience and examples on biBerk’s national site; examples are illustrative. The homepage says availability depends on the state and type of insurance; listed categories do not establish individual eligibility. | Small and midsize businesses can compare Cowbell cyber options, while middle-market firms can consider broader programs; Prime 100 targets up to $100 million revenue and Prime 250/Tech up to $1 billion. 24,25,26,27,30Company-reported. Published U.S. product appetites; eligibility is subject to underwriting and product-specific class restrictions. |
| Coverage lines | 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. 5Company-reported. Entity: 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. biBerk describes its small-business BOP as combining General Liability and commercial property in one policy. Its page gives examples of third-party injury/property-damage liability and protection for buildings or leased space, contents, inventory, tools, and business income after covered property damage; the issued policy controls. 6Company-reported. Entity: biBerk brand. Product: small-business Business Owners Policy. State availability and exact terms depend on underwriting and the issued policy. Company-reported coverage description, not a policy-form determination. biBerk says its umbrella coverage applies only when the claim concerns coverage included in an appropriate underlying liability policy and that policy’s limits have been reached. An umbrella does not add a line such as commercial auto when the required underlying auto coverage is absent; the issued terms control. 7Company-reported. Entity: biBerk brand. Product: small-business umbrella/commercial excess. In New York, biBerk calls it commercial excess. Underlying coverage and exhaustion conditions are company-described; confirm the scheduled underlying policies and issued terms. biBerk’s commercial-auto page lists bodily-injury and property-damage liability, medical-payments/no-fault, uninsured-motorist, comprehensive, and collision coverage examples for business vehicles.

This is a catalogue-membership claim only, not a reviewed detailed-offering conclusion or coverage determination. biBerk markets Professional Liability insurance, also called Errors and Omissions (E&O), for businesses seeking protection over alleged errors or omissions in professional services. This is a catalogue-membership statement, not a determination of terms or eligibility. 13Company-reported. Entity: biBerk brand. Product: marketed small-business Professional Liability/E&O line. This is a catalogue-membership claim only; the page reviewed does not establish individual eligibility or policy terms. biBerk markets Workers’ Compensation insurance for small businesses and describes quotes and policy purchases online or with an insurance expert. State rules and underwriting determine whether it can quote a particular employer. 12Company-reported. Entity: biBerk brand. Product: marketed small-business Workers’ Compensation line. This is a catalogue-membership claim only, not a reviewed detailed-offering conclusion or coverage determination. | You can compare Cowbell’s distinct admitted Prime 100/100 Pro, non-admitted Prime 250/Prime One and follow-form excess Prime Plus programs; their revenue fit, limits, coverage and jurisdiction differ. 23,25,26,27,28,29Company-reported. Current U.S. broker-resource catalogue and product overviews. Product descriptions are illustrative and actual forms control. Cowbell advertises up to $3 million for Prime 100 Pro, up to $10 million for select Prime One risks including AI and quantum exposures, and up to $5 million excess through Prime Plus; underwriting and policy terms control. 26,28,29Company-reported. Selected differentiators in current U.S. product overviews; these are maximum advertised limits, not guaranteed buyer terms. Eligible technology firms up to $1 billion revenue can ask about non-admitted Prime Tech, combining Tech E&O and cyber with up to $5 million limits; Prime Tech Plus is a separate excess option up to $5 million. 30,31Company-reported. Current U.S. Prime Tech and Prime Tech Plus marketing overviews; product appetite and actual terms are subject to underwriting. Private companies under 250 employees and $50 million assets may consider Zurich Select Plus for D&O, EPL, fiduciary or crime; Zurich says appointed E&S wholesalers use Cowbell’s platform. 32,33Verified. Current Zurich Select Plus U.S. wholesale offering. Availability through a wholesaler does not guarantee eligibility or inclusion of all four modules. Use your issued policy to decide what is covered: Cowbell says product overviews are examples only and do not alter coverage, conditions, exclusions, availability or underwriting. 25,26,27,28,29,30,31Company-reported. Disclaimers in the current U.S. Prime 100, Prime 100 Pro, Prime 250, Prime One, Prime Plus, Prime Tech and Prime Tech Plus overviews. |
| Application process | biBerk describes an online path in which a business answers questions, chooses coverage, and pays online; it also says applicants can speak with an insurance expert. Its homepage says availability depends on the state and type of insurance; the description does not establish that every applicant can complete or bind online. 3,1Company-reported. Company-described online quote and purchase route and expert assistance for U.S. small-business applicants. 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. | Buyers work through an insurance agent or broker; appointed agents use Cowbell’s platform to quote, bind and issue eligible products, and no direct-buyer quote path was documented. 22,15,23,25Company-reported. Current public U.S. buyer and broker paths. This does not establish that every listed agent can access every Cowbell product. |
| Access to insurers | 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. Its California/Massachusetts notice separately lists each insurer’s domicile and licensed jurisdictions, but does not identify which insurer issues a particular product or policy or guarantee that a particular product is available in any jurisdiction. Check the insurer named in the issued policy. 2Company-reported. Company disclosure provided to California and Massachusetts applicants and insureds; it describes the four named insurers collectively as issuing most policies sold by biBerk and separately lists each insurer’s domicile and licensed jurisdictions. It does not identify which insurer issues a particular product or policy or guarantee that a particular product is available in any jurisdiction. | Ask which insurer is on your declarations: Cowbell names Palomar for Prime 100/100 Pro, Palomar and Chaucer for Prime 250, Chaucer for Prime One, and more general carrier descriptions for excess, Tech Plus and Select Plus. 25,26,27,28,29,31,32,21Company-reported. Named paper providers in the current reviewed product materials. The quote and policy must identify the actual insurer for a specific product, state and account. |
| Servicing and renewals | biBerk’s policyholder support page lists online routes for policy changes, business and driver updates, payments, certificates, renewal or reinstatement requests, and claims. The page does not establish turnaround time, approval, or eligibility for a requested change or renewal. 4Company-reported. Tasks and online routes listed on the public U.S. policyholder support page; not a service-level, approval, or renewal-eligibility claim. | Cowbell pairs cyber coverage with risk ratings, policyholder insights, security connectors, training and resiliency support; included access may be limited or trial-based, while some services require a subscription. 36,25,29Company-reported. Current U.S. resiliency-services catalogue and cyber product overviews. Eligibility, third-party terms and whether a service is bundled depend on the policy and service agreement. Ask your agent how to request changes or cancel; Cowbell directs policyholders to agents for cancellations and agents to Cowbell for endorsements. Prime 100 renewal proposals start around 60 days before expiry; Prime 250 requires a signed application and underwriting. 34Company-reported. Current public FAQ for P100 and P250; other products and individual policy terms may use different servicing and renewal procedures. |
| Claims assistance | 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. 14Verified. NerdWallet U.S. small-business-insurance review, updated February 13, 2026 and accessed September 29, 2026. The review attributes the comparison to NAIC company-level data but does not identify the insurer mix for a specific biBerk policy. It reports commercial liability and commercial property complaint experience for 2022–2024 relative to market share; complaint contents and underlying counts are not stated in the reviewed passage. | Cowbell says its in-house cyber claims team and response panel are available 24/7; have your policy number, incident date, details and contact ready. The issuing insurer and policy determine coverage and payment. 35,25,28Company-reported. Cowbell's current U.S. cyber claims-services page and product overviews; company-reported service description, not an independently measured outcome. |
