Our client platform handles the entire process – from data onboarding and activation through ad platforms (SSPs) to targeting, measurement, and attribution. This enables advertisers to engage audiences in environments where cookies are not available, such as connected TV (CTV), Safari browsers, and other cookieless spaces, while optimizing campaign performance.
Our client offers a service that allows advertisers to identify and reach their target audience without relying on third-party cookies. They process billions of signals from people using their TVs and browsing the web, using our unique technology and patents to build an identity graph. This
identity graph helps our clients effectively recognize and engage with audiences across different environments.
