How GroupM Built Privacy-first Data Collaboration for AI and Analytics
12-Week Delivery | Zero-Copy Collaboration
A global media group needed to collaborate on media data with clients and partners, but privacy regulations made traditional data sharing untenable. Raw customer data couldn’t be exported to shared environments.
Without data collaboration, campaign planning and ROI measurement were limited to what each party could see in isolation. Multiple clients and lines of business needed governed access — but with controls ensuring each party only saw authorised data.
ADA designed a Snowflake-based data exchange using zero-copy sharing. Clients and partners could query shared datasets without data leaving its source environment. Privacy was built into the architecture.
Child accounts per client provided governed access with audit trails. The solution included segmentation modules, activation connectors to Google and Meta, and attribution models for cross-campaign ROI.
