§ The result
Arena Analytics takes the total, XOR takes more of the criteria.
Under rubric v1.0, Arena Analytics and XOR finish 2 points apart, 32 to 30, as two Screening entries. XOR leads more of the criteria than Arena Analytics — 3 to 2 — but Article 11 Technical Documentation, which Arena Analytics leads, carries 20% of the rubric, and the weighted sum still falls to Arena Analytics. One criterion, Article 11 Technical Documentation, is both the widest raw gap (Arena Analytics 30, XOR 20) and the heaviest weighted swing, and at 20% weight it makes up 61% of the weighted advantage Arena Analytics holds across the 2 criteria it leads.
Vendor profile
Arena Analytics
Arena scores job applicants, mainly for healthcare and senior-living employers, on how likely they are to show up and stay in a specific role at a specific location, reroutes and sources candidates it rates likely to be retained, and applies the same outcome models to employee flight risk and internal mobility.
Vendor profile
XOR
XOR is a text-first conversational-AI recruiting platform that pre-screens and scores high-volume and hourly candidates with recruiter-defined knockout/scoring questions over SMS, WhatsApp, and Messenger, then auto-schedules interviews on the recruiter's calendar.
§ The record
Arena Analytics and XOR are both filed under Screening AI. They record no secondary category in common.
Both are in scope of EU AI Act, NYC LL 144, Colorado AI Act and Illinois HB 3773. Only Arena Analytics is in scope of Mobley v. Workday.

Weighted delta is the raw difference times the criterion weight, so the 5 figures above sum to +1.6 — the difference between the two totals before either is rounded. Shares are of 4.9 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +2 beside that +1.6.
§ Category-by-category
Raw score per criterion, with weighted delta.
Δ is Arena Analytics minus XOR.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.

Arena Analytics has 30 evidence rows across 7 of 7 criteria — 23 with a source URL, 7 documented absences; XOR has 18 evidence rows across 7 of 7 criteria — 11 with a source URL, 7 documented absences; some documentation or audit rows for Arena Analytics sit on a domain separate from the vendor's own site.
Provenance
The scores above are documented by 48 evidence rows on file for these two vendors: 30 for Arena Analytics, across 3 distinct source domains, and 18 for XOR, across 1 distinct source domain.
