Phone-verified B2B contact data and intent signals for EMEA-focused sales teams
Best for
Cognism is a B2B sales intelligence platform from Cognism (London, founded 2015) that provides phone-verified mobile numbers and intent signals for revenue teams. Its Diamond Data database spans 18 EMEA and North American markets, integrating with Salesforce, HubSpot, Dynamics, Salesloft, Outreach, and Pipedrive.
What Cognism does:
- •Diamond Data Phone-verified mobile numbers manually checked by Cognism's research team, reportedly achieving two-to-three times higher connect rates than standard B2B databases.
- •Intent signals Bombora-powered buyer intent data identifies companies actively researching solutions in your category, so reps prioritize accounts ready to buy.
- •AI Persona Builder Define your ideal customer profile and Cognism surfaces matching contacts with relevant firmographic and technographic filters.
- •CRM integrations Native connectors for Salesforce, HubSpot, Microsoft Dynamics, Pipedrive, Salesloft, Outreach, and Bullhorn keep enriched data synced across your stack.
- •Automation integrations Connect via Zapier and Make to trigger automated lead routing, enrichment workflows, and CRM updates without manual data entry.
- •API and batch delivery REST API for Data-as-a-Service delivery lets teams build custom data pipelines and integrate Cognism into automated [agentic](/glossary/agentic-ai) workflows.
- •Compliance screening Built-in GDPR and DNC list checking across 18 EMEA markets reduces legal risk when prospecting internationally.
Pricing:
- •Sales Intelligence Platform Per-user subscription with monthly prospecting credits for search, export, and Diamond Data access. Includes CRM integrations, compliance screening, and intent signals. Contact Cognism sales for a custom quote based on team size and credit volume.
- •Data-as-a-Service (DaaS) Custom pricing based on data volume and delivery requirements. API access and batch delivery for teams building automated enrichment pipelines. Third-party reviews estimate starting costs around $15,000 per year.
Limitations:
- •Opaque pricing with no self-serve option Cognism requires contacting sales for all quotes. No public pricing page, no free trial, and no way to evaluate cost before committing to a demo process.
- •No built-in outreach tools Cognism provides data but not email sequencing or dialer functionality. Teams need separate tools like Salesloft, Outreach, or Instantly for actual prospecting campaigns.
- •Credit-based model can surprise users Monthly credit allocations vary by plan tier, and heavy prospecting teams may exhaust credits before month-end, requiring costly top-ups.
- •Enterprise-oriented onboarding The sales-led process and premium pricing make Cognism impractical for solo operators or small teams without a dedicated outbound budget.
Our Verdict
Cognism delivers high-accuracy, phone-verified B2B contact data with strong EMEA coverage and built-in GDPR compliance. It scores 8.1/10. It is a solid choice for revenue teams that prioritize connect rates over sheer database volume. The main drawback is opaque, enterprise-level pricing that requires a sales conversation.
For the Basic User, Cognism offers a straightforward UI for daily prospecting. Diamond Data phone-verified numbers solve the frustration of bounced emails and dead phone lines. Compliance screening for 18 EMEA markets removes legal guesswork. The downside is that pricing is not public and onboarding requires a sales call, which may deter individual reps or small teams wanting to try before buying.
For the Vibe Builder, Cognism's REST API and native Zapier and Make connectors enable automated CRM enrichment and lead routing workflows. Set up triggers that push verified contacts into HubSpot or Salesforce the moment intent signals fire. The DaaS tier supports batch delivery for larger data pipelines. Limitation: DaaS pricing is custom and requires a sales conversation, which slows down builders who want to test integrations quickly.
Skip it if you need self-serve pricing or a free trial to evaluate before committing -- consider Apollo.io instead. Skip it if you want built-in email sequencing and dialer tools in one platform -- Apollo.io or Lemlist cover that. Skip it if your primary market is the US and you need maximum database size -- ZoomInfo maintains a larger US-centric footprint.
