Cognism
B2B sales intelligence with phone-verified contact data, strong in EMEA
About
Cognism is a London-based B2B sales intelligence platform known for its "Diamond Data" — mobile numbers individually verified by phone and cross-referenced against do-not-call lists — which makes it a favorite for teams prospecting in the UK and Europe. It layers contact and company data with technographics, Bombora-powered intent signals (on higher tiers), and CRM enrichment, all delivered through Salesforce and HubSpot syncs or its API.
Honest limitations: pricing is quote-only (third-party sources cite packages starting around $12,750/year), it is a data platform rather than an engagement tool so you still need a sequencer, and US/APAC coverage is thinner than its European data.
