Cognism is a B2B sales intelligence platform built around compliance and high quality mobile phone data. Founded in 2015 in London, it has become a leading data provider in Europe and a strong global alternative to ZoomInfo, known especially for phone verified mobile numbers it calls Diamond Data and for a compliance first approach that suits teams doing outreach under GDPR and similar rules. Its focus is accurate, usable, legally sound contact data.
Cognism's distinction is quality over sheer volume, and compliance by design. It verifies mobile numbers by phone, checks data against do not call registries, and is built to help teams prospect confidently in regulated markets. For sales teams selling into Europe or who prize reliable direct dials, that focus is a major draw.
Cognism is best for mid market and enterprise sales teams, especially those selling into Europe, that need accurate, compliant contact data and reliable mobile numbers. It suits teams that value data quality and legal confidence over the largest possible database. It is a weaker fit for very small teams on a budget, where Apollo or Lusha are cheaper, and in some US segments ZoomInfo still has deeper coverage.
The core strengths are phone verified mobile data, compliant contact and company data with do not call checking, buying intent through a Bombora partnership, and sales trigger events like funding and job changes. It offers unrestricted data views on many plans, a Chrome extension for prospecting on LinkedIn and company sites, and CRM and engagement integrations. Mobile accuracy and compliance are its standout attributes.
Cognism does not publish prices. It is quote based, typically sold per user with access to its data, and many plans offer unrestricted views rather than tight credit caps, which teams value. Pricing depends on seats, data packages and add ons like intent. Expect a sales led process and annual contracts. Request current pricing through the Cognism site.
Cognism integrates with Salesforce, HubSpot, Microsoft Dynamics and sales engagement tools like Outreach and Salesloft, plus a Chrome extension and API, so data flows into prospecting workflows. Its ecosystem is focused on feeding accurate, compliant data into the CRM and engagement stack.
Rather than AI as a headline, Cognism's edge is data operations: phone verifying mobiles, continuous validation, and compliance checking. It has added AI features for search and workflows, but its reputation rests on the accuracy and legality of the underlying data, which is what its customers buy it for.
Cognism is generally well regarded for usability and for support during onboarding. Its unrestricted data model and clear compliance reduce friction for teams worried about limits or legal risk. Its G2 reviews praise mobile data accuracy and compliance, with coverage in some niche US segments the occasional critique.
For a mid market or enterprise team, especially in Europe, that needs accurate mobile data and compliance confidence, Cognism is one of the strongest choices available and often worth its cost. The main cautions are quote based pricing and that in some US segments ZoomInfo has deeper coverage, so teams should test data for their specific target market during a trial.
