What is Tealium?
Tealium is a customer data platform that collects data from websites, apps, servers and other sources, unifies it into customer profiles and activates it in real time across more than 1,300 integrations. The company is based in San Diego and is best known for Tealium iQ, one of the longest-running enterprise tag management systems, which it built on to create a full CDP.
The platform is made of several connected products. Tealium iQ manages client-side tags and consent, EventStream handles server-side data collection and quality, and AudienceStream builds profiles and audiences. DataAccess stores events for the long term, Moments iQ captures zero-party preferences, and Predict adds machine-learning scores. Newer features cover reverse ETL, zero-copy warehouse activation and feeding consented data to AI models and agents.

Tealium FAQ
What is Tealium used for?
Tealium is used to collect customer data from websites, apps and servers, manage marketing tags, enforce privacy consent and build real-time customer profiles. Companies then send that data and audiences to ad platforms, email tools, analytics systems and warehouses to personalize experiences and measure campaigns.
Is Tealium free?
Tealium does not advertise a free plan. Its products are aimed at enterprises and are sold through custom quotes, with the price depending on which modules you need, such as Tealium iQ, EventStream or AudienceStream, and on your data volume. Contact the sales team for a demo and quote.
What is Tealium iQ?
Tealium iQ is Tealium's tag management system. It lets teams add, edit and remove marketing and analytics tags on websites from one interface rather than changing page code. It also handles client-side consent and data collection and acts as the entry point for data that flows into the wider Tealium CDP.
Tealium vs Segment: what's the difference?
Both collect events and route them to other tools. Tealium grew out of enterprise tag management and offers deep consent controls and real-time audiences for large brands. Segment, owned by Twilio, is developer-friendly, has a free plan and is popular with startups and SaaS teams.
Does Tealium integrate with Snowflake?
Yes. Tealium offers a Snowflake connector and a Snowflake Audience Discovery App, and supports reverse ETL and zero-copy activation with cloud data platforms. This lets teams use warehouse data in Tealium audiences or send Tealium event data into Snowflake for analysis.
