Tealium

Enterprise CDP built on top of Tealium's long-established tag management layer, unifying and activating customer data in real time.

Visit Tealium Alternatives

Tealium grew out of Tealium iQ, a client-side tag management system, and extended that data-collection layer into a full customer data platform (AudienceStream) that unifies web, mobile, server-side, and cloud events into real-time customer profiles. From those profiles it can trigger actions and route data to marketing, analytics, and AI destinations, applying consent rules centrally before data reaches any downstream tool. Because its collection layer originated in tag management, it is often chosen by enterprises that already use Tealium for tagging and want to extend the same governed data layer into a CDP rather than adopting a separate vendor for collection and activation. It is cloud-hosted, processes very high event volumes, and lists over 1,300 pre-built integrations.
