More than 340 vendors now claim AI-native demand generation capabilities — a 4x increase since 2022, per IDC's 2025 MarTech Landscape Report. Yet fewer than 18% of B2B revenue leaders report measurable pipeline lift from these deployments within 12 months. This guide cuts through the noise with a five-criterion evaluation framework covering intent signal quality, model transparency, CRM orchestration depth, compliance architecture, and time-to-value benchmarks. Criteria are weighted by procurement impact, scored on a 1–5 rubric, and paired with eight vendor interrogation questions and four disqualifying red flags. Written for VP-level demand generation, RevOps, and marketing technology leaders at B2B firms with $20M–$500M ARR evaluating or re-evaluating their AI demand generation stack in 2026.

In this buyer's guide, you'll learn:

  • Why 63% of B2B teams increasing AI demand-gen spend in 2025 still missed pipeline targets — and the vendor selection patterns that explain the gap.
  • How to apply a weighted five-criterion framework (intent quality, explainability, orchestration, compliance, and onboarding velocity) to any vendor shortlist.
  • What a best-in-class scoring rubric looks like across all five criteria, from 'poor' to 'best-in-class,' with specific, auditable benchmarks.
  • Eight interrogation questions designed to expose implementation gaps that vendor demos and pitch decks systematically conceal.
  • The four hard red flags — including compliance tells and attribution sleight-of-hand — that should immediately disqualify a vendor from your evaluation.
