The yardstick for AI in HR, calibrated for people leaders.

How we test, score, and publish

Yardstick Research is an independent software research and consulting agency for B2B AI tools. We test the tools ourselves, score them on outcomes that matter, and publish the results. Methodology in plain sight, so your CHRO can sign off and your bias-audit holds up. For CHROs, VP Talent, VP People, and HRBPs, we weight Data Readiness and Tool Stack heavily because in HR your existing HRIS-of-record, ATS data feeds, and payroll integrations determine what AI you can actually deploy, and clean employee-data hygiene is the precondition for EEOC hiring-AI guidance, NYC Local Law 144 bias-audit obligations, and GDPR / CCPA employee-data protections. Here's how that actually happens:

1. 01

   We evaluate every HR vendor on this list using public information and free-tier hands-on.

   Our researchers evaluate each vendor on the list using a defensible mix of inputs: vendor documentation and pricing pages, free-tier or trial-seat hands-on where the vendor offers one, video walkthroughs, third-party reviews (G2, Capterra, Gartner Peer Insights), published customer case studies, practitioner discussion (LinkedIn, HR Brew, HR Executive, SHRM, HR Tech Conference coverage, Josh Bersin Academy), and recent funding and news coverage. Where we can sign up and exercise the product directly, we do, and grade the output against a sample workflow: in the HR case, a candidate-sourcing query, a screening assessment, an employee-engagement pulse survey, or a learning-path recommendation. We do not pay for paid tiers and we do not run a held-out applicant-pool benchmark through every tool. Both are cost-prohibitive at the scale this guide covers.

   Every claim in a tear-sheet is labelled MEASURED (free-tier hands-on observation, or output graded against a sample workflow), ESTIMATED (cost-per-seat efficiency derived from the vendor's pricing page and feature limits), or CITED (vendor-published or third-party benchmark, with the source linked).

2. 02

   We score on outcomes buyers care about, with weights we publish.

   Vendor decks sell features. HR operators actually buy outcomes: time-to-fill, quality-of-hire, candidate-NPS, retention rate, and internal-mobility rate. We score five dimensions: Strategy & Use Cases, Data Readiness, Tool Stack, Team & Workflow, and Budget & Procurement. Industry benchmarks for mature HR operators sit at 55 / 55 / 45 / 55 / 60 percent of each dimension's maximum. The dimensions and benchmarks are public so your CHRO can sign off on the pick, and so vendors can't quietly negotiate them. The audit also captures your operating baselines (time-to-fill, quality-of-hire 1-year retention, voluntary turnover, employee engagement, tier-1 case deflection, adverse-impact ratio) and fans return-on-investment scenarios out per selected baseline.

3. 03

   We publish. Vendors check facts. Affiliate links are disclosed.

   Every vendor receives their scored tear-sheet seven days before publication and can flag factual errors (wrong pricing tier, misquoted feature, integration listed as native that's actually via a third party). Rankings can't be appealed; only factual corrections are accepted. Where the guide links to a vendor's product, that link may earn us a commission. Disclosed on every page where the link appears. Vendors do not pay for inclusion, placement, or ranking.
