Best for Ad-tech platforms and brands needing privacy-preserving identity matching via API rather than a full marketing suite. Brands needing one consistent, privacy-conscious identifier to connect CRM data to advertising and measurement partners. Advertisers wanting an identity graph backed by a large offline consumer data asset, with attribution built in. Brands already working with Merkle/Dentsu on media or CX who want identity resolution bundled into that relationship.
