Cognism is a London-headquartered sales intelligence company that helps B2B revenue teams discover, connect with, and convert ideal buyers using accurate, compliant data. Founded in 2015 by James Isilay and Stjepan Buljat, the platform combines a large global B2B database with phone-verified mobile numbers, intent and signal data, and deep CRM integrations to make outbound prospecting more predictable and scalable. Its core focus is on high-quality European data and compliant processing aligned with GDPR and CCPA.
The flagship offering, Cognism Sales Companion, includes a web application, powerful segmentation and persona-building tools, and a Chrome extension that overlays Cognism data on LinkedIn, Sales Navigator, company websites and leading CRMs. Revenue teams can filter by company size, industry, seniority, skills, technologies and buying signals, then sync cleaned and enriched records directly into Salesforce, HubSpot, Microsoft Dynamics 365, Pipedrive, Outreach, Salesloft, Bullhorn and other tools. Phone-verified Diamond Data® gives users access to highly accurate mobile numbers and direct dials, significantly improving connect rates for outbound calling.
Cognism has grown rapidly through both organic expansion and acquisitions. It acquired Mailtastic in 2020 to add email signature marketing capabilities, and Kaspr in 2022 to strengthen its sales prospecting footprint in France. Backed by more than $128 million in venture funding, Cognism now serves over 4,000 customers worldwide, ranging from high-growth SaaS companies to large enterprises in sectors like technology, financial services and professional services. The company operates globally with hubs in London, Skopje and several other European cities.
Positioned as a premium alternative to US-centric providers, Cognism differentiates with its compliance-first data sourcing, extensive Do-Not-Call screening, and security posture including ISO 27001, ISO 27701 and SOC 2 Type II. The platform is consistently rated highly on G2, Capterra and TrustRadius for data quality, ease of use and support, making it a strong choice for teams that rely on phone-based outbound and need deep coverage across EMEA.
