Data clean room
Privacy-preserving environment for joining first-party + platform data.
A data clean room is a privacy-preserving environment (Google Ads Data Hub, Amazon Marketing Cloud, LiveRamp Embedded Identity, AWS Clean Rooms) that lets advertisers join their first-party CRM data with platform-side ad-exposure data without either side seeing the raw user-level data. Key infrastructure for post-cookie attribution, lookalike-audience building, and ROAS measurement. Typical cost: $20K–$200K/year minimum for tier-1 clean rooms.
Example
DTC brand uploads first-party purchaser-list to Amazon Marketing Cloud, joins with AMC's exposure data, finds that AMC-DSP impressions had 12% incremental purchase lift over un-exposed control — re-allocates display budget toward AMC.
