Wave 9 measured Hannover Rück Property Cat XL Treaty Reinsurance across Cody Gate-1 (3 providers, 18 datapoints, German queries, 0 errors). a fleet wave is queued for Wave 9b — Usability axis on this wave reflects structural defaults for the catalog_only B2B reinsurance close. The hannover-re.com surface carries the line-of-business overview, the lean-operations differentiator (Hannover Rück runs one of the lowest expense ratios in global reinsurance, a structural cost advantage on follow-line capacity), and the specialty-lines positioning (aviation, marine, credit + surety, agricultural). The brand surface is text-readable and code-extractable for the line description; the per-breed access profile under a real agent-fleet test lands in Wave 9b. The renewal cycle is intermediated by the same broker layer that intermediates Munich Re — Aon, Guy Carpenter, Gallagher Re. Hannover Rück differentiates on price discipline and capacity flexibility, not on a different procurement path.
One label, many breeds. From a plain reader to an autonomous operator, the kinds behind ChatGPT, Perplexity, and Claude Code:
Found, and able to transact?
Two questions, measured separately. A brand can be recommended and still un-buyable, or perfectly buyable and never found.
When someone asks an agent to secure Property Cat XL Treaty capacity, does it route to Hannover Rück?
Hannover Rück comes up about a quarter of the time. The rest of the time, an agent recommends an alternative first.
Discoverability · 18-datapoint auditOnce an agent is on Hannover Rück's site, can it reach a broker-submission pathway for a Property Cat XL Treaty renewal?
Search-class agents surface a quote in some runs; the full agent-fleet access profile lands in a later wave.
Evidence · 65 / 100 A measure of how provable and consistent the result is, grounded in cross-method ground-truth agreement (the methods that ran returned the same price), not a separate measured run. A confidence layer on the two scores above, not a third sales axis.
What this means for Hannover Rück.
On product discovery, Hannover Rück is not lacking findability — the brand is in the global top five reinsurers, named in every Property Cat XL capacity question alongside Munich Re, Swiss Re, SCOR, and Lloyd's syndicates. The gap is not the brand-own surface. It is the B2B reinsurance procurement mode: Property Cat XL Treaty placements do not run on a public-facing self-service flow. They run through the broker layer (Aon, Guy Carpenter, Gallagher Re). The agent reaches hannover-re.com, reads the line-of-business overview and the lean-ops differentiator, then routes the broker submission. Hannover Rück owns the price-discipline story, the broker owns the placement.
What changes the outcome is closing the surface-to-broker gap. The brand-own page surfaces the lean-ops story cleanly. The remaining lever is on the channel side: the agent reads the hannover-re.com line description, then has to identify the right reinsurance broker to submit through. Named Hyperize offerings here: Answer Pages on "Welcher Rückversicherer bietet die niedrigste Expense Ratio bei Property Cat XL Capacity?" that route directly to the brand-own lean-ops differentiator plus the broker-channel discovery, and Reference Pages that make Hannover Rück's specialty-lines taxonomy (aviation, marine, credit + surety, agricultural, cyber) agent-readable rather than human-readable. If your brand sits behind brokers, distributors, or tied agents, this is the AI test that decides whether agents reach you first or your channel does.
The proof isn't more content. It's a repeatable lift in whether agents find, verify, cite, recommend, and complete the brand journey directly — re-measured each wave.

Fairness note
Wave 9 Q2 2026 partial measurement. Single task (Hannover Rück Property Cat XL Treaty Reinsurance, quote_ready close, European primary insurer 1 January renewal placement). AI Visibility from Cody Gate-1 (Q2-2026, openai/perplexity/anthropic, DE language, 18/18 valid datapoints). AI Usability axis pending a fleet wave (queued Wave 9b) — current Usability score reflects structural defaults for the catalog_only B2B reinsurance close, not a measured per-breed access profile. Fairness Review pending the sector fairness grid.
How the score was produced.
Discoverability is audit-pipeline-derived. 3-provider sample (openai, perplexity, anthropic), 3 query variants per task, 2 runs per variant · 18 valid datapoints scored against a five-state handoff cascade. [S1]
AI Usability is derived from the access-profile above (usability-derivation/v1): how far the best agent reached (close state) modulated by how many agent classes succeeded. The per-class profile is the truth; the score is a reproducible summary of it, not a separate rating. Fleet phases (HTTP / Coding / Browser / ACT) produce the profile. [S2]
Agent Success Score = (AI Visibility × 0.20) + (AI Usability × 0.70) + (Evidence × 0.10)
On a 0–100 scale, displayed 0–10. AI Usability bundles the agent's reach + completion; AI Visibility is audit-derived discoverability. Weighting is public; the per-prompt derivation is not.
Measurement scope
Confidence C · one measured task on a 3-provider track (openai, perplexity, anthropic). Confidence promotes to B with a second task plus a fourth provider on the next wave.
