Methodology

Where ratings come from

Every platform we cover is rated against a 1.0–5.0 scale based on two inputs: verified operator submissions (people who run the platform in production at their company) and our own head-to-head evaluation across the four use case categories.

• Verified operator reviews are weighted highest. Verification requires a public LinkedIn profile whose current or recent role matches the role the submitter claims — the same standard G2 holds reviewers to. Contact details are used only for verification and are never published or shared with vendors.
• Editorial evaluation is run by our panel against a standard scenario set per use case. Results inform the long-form description on each vendor page.
• Public reporting on product status (retirements, regulatory actions, executive changes affecting customer outcomes) can shift a rating even when live reviews are still arriving.

Use case categories

A platform that wins for customer service does not necessarily win for cold outbound. We rank platforms within each category independently, and the homepage filter changes the order accordingly.

• Sales teams — inbound qualification, outbound recovery, booking.
• Marketing teams — speed-to-lead, campaign follow-up, attribution.
• Engineering teams — voice as infrastructure, embedded in product.
• Customer service — deflection, escalation handling, multi-turn support.

What we don't do

• We do not accept payment from voice AI vendors for placement.
• We do not invent reviews or roll up G2 / Capterra / TrustRadius averages without re-verification. When we surface external reviews on a vendor page, the source platform is labeled and the text is verbatim — never edited or paraphrased.
• We do not edit reviews to favor or disfavor a vendor.

Corrections

If a vendor disputes an assessment, we will re-evaluate against the same standard scenario set and update the long-form description if warranted. Ratings do not change without new operator data or material public reporting.
