About
Premium B2B sales-intelligence platform known for phone-verified "Diamond Data" mobile numbers and GDPR-compliant European coverage. ~4.6/5 G2.
Across the review sites
What people love
- Reviewers repeatedly cite how much manual prospecting time Cognism saves once contact data is set up correctly.
- Diamond Data's phone-verified mobile numbers noticeably lift connect rates versus other providers, especially in Europe.
- New users get productive fast — reviewers describe the interface as intuitive with a short learning curve.
- Native CRM integration lets teams push enriched contacts straight into their existing workflow.
- Overall data accuracy and reliability come up again and again as the reason reps trust their outreach lists.
What could be improved
- Coverage outside Europe (APAC, niche industries, smaller companies) is noticeably thinner than the strong UK/EU dataset.
- Data isn't uniformly fresh — reviewers flag bounced emails, wrong numbers, and outdated contacts in a meaningful minority of records.
- Batch export/download limits (e.g. saving contacts 25 at a time) slow down building large target-account lists.
- Account owners report limited control over billing, payment methods, and renewals, which they say favors Cognism's retention over their own flexibility.
- Not everything Cognism captures reliably flows through to connected CRMs, forcing manual cross-referencing.
- A cluster of Trustpilot reviews from non-customers allege Cognism sourced and shared their personal mobile numbers without consent, a recurring GDPR-compliance complaint distinct from product reviews.

What people are saying
"I use Cognism mainly for prospecting into UK and European accounts, and the biggest win for me has been the mobile number accuracy, my connection rates are noticeably better than what I got with ZoomInfo, and it saves me a lot of time I used to lose to corporate switchboards."
"Cognism is a powerhouse for B2B lead generation and database enrichment. The coverage of contact details and direct-dial numbers is outstanding, especially for European markets. The learning curve is very gentle, meaning our team got up to speed almost instantly. Furthermore, their strict GDPR compliance gives us absolute peace of mind regarding data security."
"We do battle a little with contact details in Italy. It's a little bit more sparse than the contact details we use in the UK."
