The short answer
Cognism and ZoomInfo are both B2B sales intelligence platforms built around a contact database, but they specialize in different territory. Cognism is a single-product sales intelligence tool built around phone-verified mobile data (“Diamond Data”) and GDPR/CCPA-first compliance tooling, with its strongest coverage in the UK and EMEA. ZoomInfo is a much larger, multi-product GTM data platform (Sales, Marketing, Talent, Operations) with a bigger US-centric database, intent data, and an AI copilot, sold to a much wider customer base. Neither publishes public pricing; both are quote-only via demo.
If your ICP sells into the UK or EMEA, you need phone-verified mobile numbers and built-in GDPR/CCPA (DNC/TPS) screening, and you want a simpler, single-product tool rather than a large multi-line suite, Cognism is the more specialized pick (reported ~$22,500/yr estimate for a 5-seat plan, quote-only).
If you need broader US contact depth, intent signals, and a platform that spans Sales, Marketing, Talent, and Operations with deep native integrations (Salesforce, HubSpot, Microsoft Dynamics, Salesloft, Outreach, Marketo), ZoomInfo’s larger scale is the stronger fit (reported ~$37,500/yr estimate for a 5-seat Advanced plan, quote-only).

Vendor profile
Cognism
Cognism is a UK-founded sales intelligence platform built around phone-verified mobile and direct-dial data it markets as “Diamond Data,” CRM enrichment, and GDPR/CCPA-first compliance tooling (DNC/TPS screening, ISO 27001, SOC 2 Type II). Founded in 2015 and headquartered in London with additional offices in the US, North Macedonia, and Croatia, it employs roughly 559 people as of 2026 (reported, up from 481 in 2023), including around 150 quota-carrying reps. Customer count is reported at approximately 6,400, a third-party estimate not confirmed on Cognism’s own site. Notable case-study clients listed on cognism.com include Redgate, Mollie, Druva, AVEVA, Kinaxis, Darwinbox, ComplyAdvantage, Coralogix, Allego, and YuLife. Cognism’s stated strength is EMEA/UK phone verification; its acknowledged weaker point is US contact depth relative to ZoomInfo. There is no public pricing page; quotes require a demo.

Capability comparison
Both platforms cover the sales-intelligence core: contact data, filtering, CRM enrichment, and compliance tooling. The gaps show up in database scale, geographic strength, product breadth, and integration depth. Cognism leads on EMEA phone verification and compliance focus; ZoomInfo leads on scale, intent data, and platform breadth.

| Intent / sales trigger signals | ✓ (included) | ✓ (core strength; sold as add-on module) |
| AI-assisted prospecting | Unverified (not confirmed on homepage) | ✓ (Copilot AI sales agent) |
| Product line breadth | ✕ (single product: sales intelligence only) | ✓ (Sales, Marketing, Talent, Operations) |

Strengths & tradeoffs
Both platforms cover the sales-intelligence core (contact data, filtering, CRM enrichment) and each side wins rows the other does not. The honest differences are geographic specialization, product breadth, and reported cost.
| Axis | Cognism | ZoomInfo |
|---|---|---|
| Scope | Single product: sales intelligence with phone-verified data and compliance tooling | Multi-product GTM platform: Sales, Marketing, Talent, Operations |

| Scale | ~559 employees; ~6,400 customers (reported estimate) | ~3,500 employees; 35,000+ customers, over half the Fortune 500 |
| Compliance | GDPR/CCPA-first (DNC/TPS screening, ISO 27001, SOC 2 Type II) built around European data law | Broader compliance posture, not positioned as an EMEA-first specialist |
| Intent data | Included as part of the platform | Positioned as a core strength, sold as an add-on module |

| Customer base | ~6,400 (reported, third-party estimate) | 35,000+ (per ZoomInfo’s own About page) |

Direct G2 fetches for both products returned HTTP 403 during research, so the ratings and review counts above come from secondary aggregator summaries, not a live G2 pull; anyone publishing or relying on these numbers should re-check both G2 listings directly before citing them. Reviewer sentiment themes are also paraphrased from aggregated summaries rather than individually attributed verbatim quotes, since G2 fetch was blocked for both. On raw scale, ZoomInfo’s review pool and customer base are roughly an order of magnitude larger than Cognism’s, which reflects company size and market breadth more than product quality. The choice here is about geographic ICP, product breadth, and budget, not which tool is “better.”
Both tools’ data is sourced from publicly available information and third-party cross-checks as of July 2026. Direct G2 fetches for both products were blocked (HTTP 403); ratings, review counts, and all pricing figures for both vendors are reported/third-party estimates, not confirmed live pulls or official price lists. Verify directly with each vendor before buying. This comparison is independent; we take no affiliate or referral fees from either vendor.
