Known for strong European coverage and phone-verified mobile numbers, Cognism is a B2B sales-intelligence platform built to supply compliant contact and company data. Its team manually verifies direct dials, so reps can reach the right prospects on the first attempt. The data comes paired with buying-intent signals, technographics, sales triggers, and CRM enrichment. Cognism leans hard on compliance, checking numbers against do-not-call lists across regions, which matters for teams selling into the UK and EU where data regulation is genuinely tight. Its Diamond-verified mobile dataset connects at notably higher rates than most competing databases, the main reason teams pick it for calling motions. Like ZoomInfo and Apollo, though, it is a broad firmographic database that gives good data without ever being the full picture, and its intent ships as a premium add-on. At Nebor we choose the data source based on the client ICP rather than defaulting to one generic database. When a client sells into Europe and needs clean, compliant mobile data that other sources miss, Cognism is a strong fit, so we sometimes connect it as one source among many. In that role it feeds verified numbers and intent into a Clay-centered system, where they get enriched, scored, and routed alongside other providers. Pricing is quote-based with a platform fee plus per-seat cost, so it earns its place mainly where European depth is the real requirement. Leaning on any single database leaves gaps. The working engine comes from how the data is actioned, not the export.
