The Winning Project: Privacy-First Cookieless User Attribution Network
The Marketing Consultancy UK award was won by the digital agency Brainlabs. Brainlabs was recognized for deploying a cookieless, privacy-first user attribution and automated media planning system for a prominent UK retail brand.
As third-party browser cookies are phased out globally, the client struggled to identify which digital channels directly generated conversions, threatening their marketing investments. Brainlabs engineered a machine learning attribution engine built entirely on first-party data and mathematical marketing mix modeling (MMM).
The system ingests anonymous customer purchase telemetry, first-party web metrics, and localized physical store traffic data, correlating them to digital marketing campaigns without tracking individual user histories. This gives the client a reliable, privacy-compliant view of user behavior, optimizing media spend allocation and driving conversion growth.
Judges' Verdict
"Brainlabs has delivered a practical solution for the modern, privacy-first web. Their cookieless attribution models demonstrate that marketers can achieve strong returns without relying on invasive tracking."
