Agency Echelon
Reference

A secure environment in which two or more parties match and analyze their data without either party seeing the other's raw records. Clean rooms are how advertisers measure and target on walled gardens (Google Ads Data Hub, Amazon Marketing Cloud, Meta Advanced Analytics) and how retailers, publishers, and brands collaborate on Second-Party Data. Vendors include LiveRamp, Snowflake, Habu (LiveRamp), and InfoSum.
