Cognism

Cognism is a B2B data company headquartered in London, founded in 2015 and now operating with over 450 professionals across offices in Boston, Paris, Cologne, Skopje, and Zadar. The company builds sales intelligence, Data-as-a-Service (DaaS), and CRM enrichment products - all built around GDPR-compliant data pipelines. That compliance angle is the real engineering challenge: maintaining accurate, up-to-date contact and company data at scale while navigating some of the strictest privacy regulations on the planet.

The threat model here isn't external attackers breaching a perimeter - it's data integrity, regulatory exposure, and the operational risk of serving stale or non-compliant records to over 4,000 customers worldwide. Engineering teams work across data ingestion, enrichment, and delivery layers, where the margin for error is measured in fines and lost trust. The stack has to handle high-volume data processing, deduplication, and real-time CRM syncing while keeping audit trails clean enough to satisfy GDPR requirements.

With $83M in annual recurring revenue and a $436M valuation, Cognism operates at a scale where data quality isn't a feature - it's the product. Security and compliance engineering roles here sit close to the core business logic, not in a silo. If you're interested in building systems where data governance, privacy engineering, and production reliability converge, this is a company where those disciplines are load-bearing.
