Armilla vs biBerk

Armilla describes AI-related insurance arranged through an MGA and separate model-assessment and contractual warranty services; biBerk sells small-business policies directly. Ask whether you need AI-specific protection or a listed business policy, and identify the insurer and terms. 3,5,4,9,10,11

Introduction

Armilla’s offering spans AI-related insurance, model assessment and a performance warranty; the warranty is contractual, not insurance. Armilla describes its insurance operation as an MGA, so the insurer—not the brand—takes policy risk. biBerk describes direct small-business insurance across common business lines. The two are not substitutes by label: identify the exposure you need to transfer before comparing products. 3 3 2 9 11

Armilla

Managing general agent

Carrier & MGA

5.2/ 10

Assessed provider: Armilla. Scope: Armilla Insurance Services Inc. as a company-named Lloyd's coverholder and AI insurance intermediary in North America, assessed against two named programmes and no others. For the AI Liability Insurance programme, also marketed as Armilla Insured, capacity is assessed as Armilla discloses it: a binding authority led by Chaucer and written by certain underwriters at Lloyd's, available to US insureds, offered through surplus lines insurers. For Armilla Guaranteed, a contractual performance warranty rather than insurance, no issuer is named and no capacity is assessed. The four reinsurers Armilla names on its broker page are attached to no programme and are not assessed as capacity for either. Financial resilience is scoped to Armilla's ability to sustain its own operations; the risk sits with the Lloyd's underwriters, whose capital is not Armilla's and is out of scope.

Key Differences Between Armilla and biBerk

For a company concerned about an AI model output causing third-party loss, Armilla’s advertised AI liability scope is the more specific starting point. It does not establish that a particular loss, fine or proceeding is covered; request the policy wording and insurer. biBerk lists small-business products such as a BOP, general liability and cyber add-ons, but its cyber option is an add-on to specified base policies rather than a stand-alone product. Ask whether the base policy and endorsement fit the exposure. 3 1 14 13

What to Confirm in Quotes

Ask Armilla who issues the policy and whether model assessment, monitoring or the separate warranty costs extra. Ask biBerk which base product supports any cyber add-on and what terms apply. Compare insurance policies separately from assessment and warranty contracts, then match exclusions, limits and reporting conditions. 1 5 13

CriteriaArmillabiBerk
Business role

Armilla offers AI insurance, performance warranties and model assessments, but the insurer—not the brand—takes on policy risk. Armilla describes its insurance operation as an MGA and Armilla Insurance Services as a Lloyd’s coverholder. 3,1,6Company-reported. Company descriptions of the Armilla brand and insurance operation; delegated authority and producer licensing have not been independently verified.

The reviewed corporate record identifies Armilla Insurance Services Inc. but does not establish California insurance authority; verify the licensed producer on your quote. Florida’s registry lists the company as a Delaware corporation. 8Verified. Exact entity spelling in corporate filing F24000002598, inspected on September 16, 2026. No California producer lookup was completed.

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. 9,10Company-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.

Customer focus

AI developers and companies deploying AI can approach Armilla, which markets to startups and large enterprises; its pages set no minimum revenue or funding stage and do not guarantee a bootstrapped company qualifies. 6,2Company-reported. Published customer descriptions; no inferred startup eligibility thresholds.

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. 11,9Company-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.

Coverage lines

If an AI error causes a covered third-party loss, Armilla’s standalone liability brief lists possible areas such as model errors, hallucinations, harmful outputs, agent mistakes, non-breach data leakage, property damage and regulatory proceedings. These are advertised scopes, not confirmation a particular loss or fine is insured. 3Company-reported. Direct product brief; no policy wording reviewed. Sample areas are not separately marketed general liability, cyber, media or property policies.

If you promise an AI system will meet a performance target, Armilla Guaranteed is a contractual warranty rather than insurance; Armilla says it funds remedies for missed metrics and may refund the buyer if remediation fails. Its FAQ lists misuse, unauthorized changes and external events as typical exclusions. 2,4Company-reported. Warranty description, distinct from affirmative AI liability insurance; no executed warranty or issuer agreement inspected.

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. 13Company-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. 14Company-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. 15Company-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. Which options apply depends on the policy selected and issued. 16Company-reported. Entity: biBerk brand. Product: small-business commercial auto. Vehicle eligibility and availability depend on underwriting and state; page examples do not establish coverage under an individual policy.

biBerk markets General Liability insurance for small businesses and says it is offered in many states. The page does not establish availability or eligibility for a particular business or state. 19Company-reported. Entity: biBerk brand. Product: marketed small-business General Liability line. 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. 21Company-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. 20Company-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.

Application process

Expect an AI risk assessment before Armilla proposes insurance or a warranty; its site directs buyers to contact the team, and coverage requires written confirmation and completed underwriting. 2,1Company-reported. Published process, not a submitted application, quote, binding test or promised turnaround.

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. 11,9Company-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.

Access to insurers

Ask for the insurer and syndicate named on your quote: Armilla names certain Lloyd’s underwriters and lists Chaucer, Axis Capital and Convex as backing partners, but does not identify the contracting insurer for each quote. 1,3Company-reported. AI liability only. Partner names do not establish that each participates in every placement; no ratings independently verified.

Before relying on a performance warranty, identify who owes the remedy and whether you have rights against a backing insurer; the brief lists Chaucer Group, Greenlight Re and Swiss Re but does not name the legal warranty issuer or California contract. 4Company-reported. Warranty partner disclosure only; no inference that backing partners directly insure the enterprise buyer.

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. 10Company-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.
