Cognism

Cognism is a B2B data provider focused on reaching decision makers by phone and email, with particularly strong coverage in Europe and the UK. It is best known for Diamond Data, mobile numbers that its team has verified by phone, which gives cold callers a much higher connect rate than unverified numbers.

The platform lets you search for contacts and companies with detailed filters, reveal emails and mobiles, enrich CRM records and track intent signals. Cognism puts a lot of emphasis on compliance, checking data against do-not-call lists in several countries and building its processes around GDPR, which matters to teams selling into Europe. It also owns Kaspr, a lighter LinkedIn contact finder aimed at individual users.

Cognism suits mid-market and enterprise sales teams, especially those doing outbound calling into EMEA, that need reliable mobile numbers and compliant data.

Pricing is custom and only available through sales, with annual contracts and no monthly option. Buyer reports put typical contracts at about $18,000 to $36,000 a year or more, made up of a platform fee plus per-seat costs, with phone-verified data costing extra.
