What reviewers across the web say
Cognism scores well with buyers (4.5 on G2 across ~1,200 reviews, 4.7 on Capterra) and is the community's default recommendation for GDPR-compliant European data and verified mobile numbers. The consistent knocks are expensive, opaque pricing that shuts out small teams, weaker US coverage, and the gap between the headline accuracy claim and the full database. Data-subject privacy complaints drive a much lower Trustpilot score.
