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.
Aon
BrokerBroker
6.7/ 10Assessed provider: Aon. Scope: Aon group commercial insurance brokerage, assessed at brand level from Aon's published terms, its 2025 SEC filing, and U.S., U.K. and Irish regulator records. It does not assess a single producing entity, insurer or placement, and it is not a ruling on Aon's consulting or benefits businesses.
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.

Broker and Managing General Agency Roles
Aon’s U.S. Commercial Risk terms describe Aon as broker of record for certain insurance programs. Armilla describes its insurance operation as a managing general agency (MGA), meaning it works under authority delegated by insurers; the insurer, not the Armilla brand, carries policy risk. These are different roles in a placement, not interchangeable versions of one policy.
Aon’s U.S. Commercial Risk terms describe Commercial Risk Solutions U.S. as broker of record for certain insurance programs. Separate electronic-delivery terms name Aon Risk Services Companies, Inc. acting for itself and licensed brokerage subsidiaries to deliver arranged policies; the terms define an insurer as the policy issuer and risk bearer. These group-level descriptions do not identify the producer or authority for a particular placement. 1,2Company-reported. Company-reported U.S. Commercial Risk brokerage and electronic-delivery terms; certain programs only. No specific insured, licensed producer, appointment, policy issuer, state authority or placement was matched.
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. 17,15,20Company-reported. Company descriptions of the Armilla brand and insurance operation; delegated authority and producer licensing have not been independently verified.
If you need a middle-market brokerage relationship or are evaluating a specialist AI route, the public descriptions point to different scopes. Aon’s Middle Market practice serves mid-sized organizations across North America without a published numeric cutoff. Armilla markets to AI developers and companies deploying AI, from startups to large enterprises, but does not promise that every startup qualifies.
Aon markets a dedicated Middle Market practice for mid-sized organizations and says it serves growing businesses across North America. The reviewed page gives no numerical size cutoff and does not establish U.S.-only eligibility; Aon’s broader global client statement describes the parent’s client base, not this practice’s eligibility rules. 4,3Company-reported. Company-reported marketing page, North America; no numerical revenue, employee-count, state or U.S.-only eligibility definition is stated.
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. 20,16Company-reported. Published customer descriptions; no inferred startup eligibility thresholds.
What the Intake Requires
For selected U.S. programs, Aon says it helps prepare underwriting information and applications and obtains the client’s instructions to bind a specific program. Armilla says buyers should expect an AI risk assessment before it proposes insurance or a warranty; coverage still requires written confirmation and completed underwriting.
For certain U.S. Commercial Risk programs, Aon says it consults with the client about market conditions, insurers to approach and program strategy, helps prepare underwriting information and applications, and obtains the client’s instructions to bind specific programs based on Aon’s proposal. The client signs applications that require a signature. 1Company-reported. Company-reported contractual terms for certain U.S. Commercial Risk programs; not a universal workflow, online checkout claim, insurer role or guarantee that a quote can bind.
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. 16,15Company-reported. Published process, not a submitted application, quote, binding test or promised turnaround.
If your concern is a specific AI deployment, give Armilla the model and use-case details requested during its assessment and ask which insurer would issue the policy. If you need several commercial lines, ask Aon which producing entity and insurer would handle each one. Neither company-level description identifies the issuer for a specific quote. 16 1 2
What to Confirm in Quotes
- Ask Armilla whether the proposal is insurance or a performance warranty, which legal entity acts as producer or MGA, and which insurer takes the risk. 17 18
- Ask Aon to identify the producer, insurer, state authority, policy terms, and compensation for every proposed coverage. 1
- Compare the written scope, limits, exclusions, retentions, and claims-notice duties. AI insurance and a broader commercial placement should not be treated as equivalent coverage based on brand descriptions. 16 1
