How We Verify Vendor Pricing and Compliance Data

How we pick vendors for coverage

The 14 named vendors in the comparison matrix and the 8 additional vendors referenced in the at-a-glance table are selected by at least two of four inclusion criteria: (1) presence in G2's Leader or High Performer quadrant for Conversation Intelligence, AI Sales Assistants, AI Voice Agents, or Sales Engagement in the last 12 months; (2) procurement-data presence on Vendr's public marketplace or named in third-party buyer research (Marketbetter, Landbase, ColdReach, NimitAI, SyncGTM); (3) active 2025-2026 marketing presence (LinkedIn paid spend, public funding round, named in trade press); (4) a public case study or pricing reference from a recognisable buyer.

Coverage is reviewed quarterly. A vendor that no longer meets at least two criteria is removed from the matrix and the per-page review is archived rather than deleted. New vendors that cross the threshold are added at the next quarterly review. The 22+ figure on the home page reflects the larger at-a-glance set including vendors covered in shallower form on the categories explainer.

How we verify pricing

Enterprise AI sales platforms almost never publish list prices. Gong, Chorus by ZoomInfo, Clari Copilot, 11x, Artisan, and Regie.ai all gate pricing behind a demo or sales conversation. The reasons are commercial: pricing is volume-based, negotiated case by case, and bundled with services, integration scope, and contract length. Vendors actively discourage public pricing disclosure because list-price transparency removes a key lever in the sales motion.

As a result, published pricing on this site is reported as a typical band, not a list price, and is always flagged with an amber "vendor-stated" or "not independently verified" banner near the price. Pricing bands are sourced from converging signals: Vendr marketplace procurement data; Marketbetter, Landbase, ColdReach, NimitAI, Outdoo, Prospeo, SyncGTM, Capterra, TrustRadius third-party buyer research; G2 deal data; published case-study disclosures where pricing was referenced by the vendor or the customer; public US state and municipal RFP responses where AI sales tools are listed; customer interviews; the vendor's own published rate cards where they exist (Vapi, Retell AI, and Bland publish per-minute infrastructure pricing).

Where the signals converge inside a band, we publish the band. Where they conflict materially, we publish the wider band and flag the dispersion. Every pricing surface carries a "verify before purchase" instruction. The bands are intended as a procurement anchor to test against the vendor quote, not a substitute for a real quote. Pricing is refreshed quarterly. Vapi, Retell, Bland, and Synthflow per-minute rates are checked against the vendor's public pricing page each refresh.

How we verify compliance status

TCPA coverage references the FCC's Declaratory Ruling 24-17 (adopted 8 February 2024) which classifies AI-generated voice as an "artificial or prerecorded voice" under 47 U.S.C. 227(b)(1)(A) and (B). Statutory damages of $500 per call for negligent violation and $1,500 per call for wilful violation are read from the statute as written. FCC public notices and enforcement bureau orders are the canonical source for any updates.

California CIPA coverage references California Penal Code section 632 and the Ambriz v Google (N.D. Cal. 2023) and Javier v Assurance IQ (9th Cir. 2022) rulings, which extend two-party-consent obligations to AI analysis of call content where a California party is on the call. Two-party consent state list is cross-referenced from Reporters Committee for Freedom of the Press, the National Conference of State Legislatures, and individual state statutes.

EU GDPR coverage references Regulation (EU) 2016/679, particularly Article 6 (lawful basis), Article 22 (automated decision-making), and the European Data Protection Board guidelines on cold-marketing communications. EU AI Act (Regulation (EU) 2024/1689) is referenced where relevant; the bulk of the Act applies from 2 August 2026, so phase-in dates are explicit on the legal page.

Vendor compliance posture (whether a given vendor publishes a TCPA-compliance Trust Center page, what consent disclosures it ships in the default voice agent template, how it handles CIPA two-party consent) is verified from the vendor's own public documentation, support center articles, security or trust pages, and the actual product UI where accessible. Where the vendor does not publish a clear position, we record the gap rather than fabricate one.

How we handle conflicts of interest

As of May 2026, agenticsalescall.com has no affiliate, referral, or commission relationship with any of the 22+ vendors covered. There are no sponsored slots in the comparison matrix or the per-vendor review pages. There is no pay-to-rank logic anywhere on the site. No vendor has previewed, edited, or approved content in advance of publication.

If an affiliate or referral relationship is added in the future, the policy is: inline disclosure on every page that contains a paid link; blanket disclosure on the about page and on this methodology page; no change to ranking or scoring; explicit notice in the affected vendor's review section that an affiliate relationship exists. Ranking and scoring will not be influenced by commission rate.

Vendor outreach asking for inclusion, rating change, language softening, or removal of caveats is logged and refused. Threats of legal action are referred to counsel and do not change published positions unless the underlying factual claim is shown to be incorrect.

Refresh cadence

Pricing is refreshed quarterly. Compliance status is refreshed on the same quarterly cycle plus event-driven refreshes when: a new FCC ruling, declaratory order, or enforcement bureau action publishes that affects AI voice classification; a new state recording-consent statute is enacted; an EU AI Act phase takes effect; a high-profile CIPA, TCPA, or GDPR enforcement action is filed against a vendor that we cover; or a material corporate event (acquisition, leadership change, product withdrawal) is announced for any covered vendor.

The "Last verified" date in every page hero reflects the most recent full-site verification across pricing and compliance. Body-content statements like "as of April 2026 Retell is best-in-class" or "at April 2026 pricing the cost per meeting was $167" describe the state on a specific historical date and are honest historical records; they are not retro-edited when the page is re-verified. The current verification date is May 2026.
