Current Spot Scores
Each score uses the rubric for that provider’s documented role. Providers with more than one role may have a score for each.
Armilla
Managing general agentCarrier & MGA
5.2/ 10Assessed 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.
WTW
BrokerBroker
7.0/ 10Assessed provider: WTW. Scope: WTW commercial insurance brokerage (Corporate Risk & Broking), assessed at brand level from WTW's terms, its 2025 SEC filing and U.S., U.K., Irish and Belgian regulator records. It does not assess one placement, one insurer, or WTW's consulting, benefits or investment businesses.

Read WTW reviewsAI-Specific Product or Broker-Arranged Program
Armilla’s materials distinguish its AI liability insurance, a contractual performance warranty and model-assessment services. Its public disclosure says the insurance is offered through surplus-lines insurers and underwritten by certain Lloyd’s underwriters; the specific carrier or syndicate for a quote remains to be confirmed. WTW’s North American terms describe a client-intermediary role for Corporate Risk & Broking and possible insurer-side services by affiliates in some arrangements. These are different roles and product types: an AI liability product or warranty should not be compared with a broker’s general placement capability as though they were the same policy. 3 1 6 1 3 2 4 9 10
Buyer Need and Product Scope
Armilla’s AI liability brief lists possible issues such as model errors, hallucinations, harmful outputs and agent mistakes; it does not establish that a specific event or regulatory fine is insured. WTW’s surfaced evidence here is for cargo and a data-center program that includes broader protection for construction and operations. WTW’s page says its data-center capacity is at least $3 billion aggregate, not per location or guaranteed to an applicant, and does not name the insurer. A buyer should first map the exposure, then request exact wording and limits from each company for the same event and insured entity. 3 12 9 10
Assessment and Placement Process
Armilla says buyers begin with an AI risk assessment before it customizes an insurance or warranty proposal; specific assessment deliverables, remediation and reporting terms need confirmation. Insurance coverage still requires underwriting and written confirmation; assessment work does not guarantee coverage. WTW’s terms distinguish quotes from insurer commitments and describe securing a binder after bind instructions, as well as reviewing policy documents against negotiated instructions. Ask Armilla what is included in an assessment versus its insurance offer, and ask WTW who the insurer and any delegated administrator will be on the intended placement. 2 1 9 10 9 10
What to Confirm in Quotes
For Armilla, request the legal warranty obligor or policy issuer, Lloyd’s underwriter details, territory, exclusions and any extra assessment or monitoring fees. For WTW, request the contracting intermediary, named insurer, compensation and policy wording. The reviewed WTW pages do not identify an insurer for the named data-center program; Armilla’s source also does not identify the Lloyd’s syndicate participating in a specific buyer’s quote. 4 6 7 11 9 10

What each provider documents about the services you may need
| Criteria | Armilla | WTW |
|---|---|---|
| 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. | For Corporate Risk & Broking engagements governed by its North American terms, WTW says it normally acts as the client’s insurance intermediary. The terms separately disclose that WTW or affiliates may provide insurer-side services, including in some MGA or program-manager arrangements. 9,10Company-reported. Corporate Risk & Broking engagements governed by WTW’s North American terms. This describes the ordinary role under those terms and the disclosed possibility of separate insurer-side services; it does not establish an insurer-side role in a particular engagement or make every WTW business exclusively buyer-side. WTW’s US product disclosures name Willis Towers Watson Northeast, Inc. as one of the licensed entities through which the group offers insurance products. WTW plc’s 2025 subsidiary exhibit lists that company among its subsidiaries as of December 31, 2025, but does not identify its direct or intermediate owner. 11,15Company-reported. WTW group-level US product-distribution disclosure and WTW plc Exhibit 21.1 dated 2025-12-31. “Licensed entity” is the company’s description; neither source verifies current authority by state or line, identifies the producer for a particular placement, or establishes the direct/intermediate ownership chain. |
| 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. | At WTW’s December 2024 Investor Day, management described Risk & Broking as roughly half large business and half middle market and below; the answer did not give a US-specific share. 13Company-reported. Management commentary in the December 3, 2024 Investor Day Risk & Broking Q&A. The answer says “our business”; it does not expressly characterize the split as worldwide, provide a US-specific share or customer count, or guarantee account-tier eligibility. WTW’s US manufacturing practice says it combines manufacturing expertise and data analytics in insurance-program design, and that its broking specialists have access to the global insurance market to identify insurer partners suited to a client’s risk. 12Company-reported. WTW’s US manufacturing industry page, “How we serve our clients.” This is a company-described practice approach, not independent evidence of actual placement breadth, a guaranteed insurer fit, or a placement outcome. |
| 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. | Under WTW’s North American Corporate Risk & Broking terms, an insurer quote is an offer, not confirmation of coverage, and may change or be withdrawn before the client orders binding. If the client chooses to bind, WTW says it will secure a formal insurer commitment, typically a binder. 9,10Company-reported. Commercial placements governed by WTW’s North American Corporate Risk & Broking terms, June 1, 2025, p. 4. An insurer commitment/binder follows the client’s order to bind; this does not establish a self-service online journey or promise that a quote will remain available. |
| Servicing and renewals | Armilla says buyers begin with an AI risk assessment before it customizes an insurance or warranty proposal. Confirm the assessment deliverables, monitoring and retesting terms in the proposal. 2Company-reported. Initial assessment described on the AI insurance page; reviewed evidence does not establish specific assessment deliverables, monitoring or retesting terms. Price monitoring and retesting separately unless the proposal includes them: reviewed pages do not explain insurance renewal or whether ongoing model monitoring is included in premium. 5,2Not publicly disclosed. Limited to public product and assessment pages reviewed September 16, 2026. | WTW’s North American terms say it reviews binders, policies and endorsements against negotiated specifications and client instructions and advises on errors or recommended changes. The terms also expect the client to review those documents. 9,10Company-reported. Clients governed by WTW’s North American Corporate Risk & Broking terms, June 1, 2025, p. 5. This describes a stated document-review process and the client’s separate essential review duty; it is not a guarantee all errors will be detected or corrected. |
