Premium B2B contact data with GDPR-compliant EMEA coverage and Diamond Data
Cognism is a leading sales intelligence platform that provides verified B2B contact data with specialized focus on European, Middle Eastern, and African (EMEA) markets. Founded in 2015 in the UK, Cognism was built from the ground up to comply with GDPR and other international privacy regulations, making it the trusted choice for go-to-market teams targeting global markets. The platform gives sales, marketing, and revenue teams access to over 200 million verified B2B contacts across EMEA, North America, and APAC regions. Cognism's standout feature is Diamond Data — phone-verified mobile numbers that achieve 98% accuracy, significantly higher than the industry average of 60-70%. Each Diamond contact's mobile number is manually verified by Cognism's team, who physically call numbers to confirm they're correct and currently in use. Cognism combines premium data quality with AI-powered prospecting tools through its Sales Companion feature, which provides real-time signals like job changes, funding announcements, and hiring trends. The platform integrates seamlessly with major CRMs including Salesforce, HubSpot, Microsoft Dynamics, and sales engagement platforms like Outreach and Salesloft.
