About
Cognism is a B2B sales intelligence platform founded in 2016 and headquartered in London, United Kingdom. The company was built to solve a persistent pain point for European sales teams: the lack of a reliable, GDPR-compliant contact database for outbound prospecting. Cognism's platform combines a 440 million contact database with phone-verified mobile numbers, intent data, and technographic signals to help sales and marketing teams identify and reach their ideal buyers more effectively than legacy static databases allow.\n\nCognism's core product provides sales teams with verified business contact data, company firmographics, and buying intent signals through a prospecting interface and native integrations with CRM platforms including Salesforce and HubSpot. In 2025, the company launched Sales Companion, an AI-powered prospecting assistant that surfaces timely outreach recommendations and automates data enrichment workflows. Cognism differentiates from US-centric competitors like ZoomInfo through its deep European data coverage, GDPR-compliant architecture, and phone-verified mobile numbers — a premium that directly drives higher connection rates on cold calls.\n\nCognism reached $83 million in revenue in 2024, a 30% year-over-year increase, serving 6,400 customers on $123.5 million in total funding at a $450 million valuation. The company is the recognized leader in B2B sales intelligence for European markets and is expanding actively in North America. It competes with ZoomInfo, Apollo.io, and Lusha, but its compliance-first positioning and European market depth create a defensible niche that US-headquartered competitors have struggled to penetrate effectively.
