Companies Using Tealium AudienceStream

Established companies, many of them large, in retail, health care and insurance. When we loaded their pages on 14 November 2026, CDW, Texas Instruments, ABN AMRO, Travelers, EssilorLuxottica and Penguin Random House all sent data to Tealium's tealiumiq.com servers. Of the 301 matched companies, 34.25% have more than 1,000 staff and 26.67% were founded before 1960.

Our November 2026 crawl counts 553 domains calling tealiumiq.com, after removing 901 alias, microsite, platform, duplicate and ID-sync domains. They're domains, not customers: in our page-source census, the 160 domains that print their Tealium account share 73 accounts. 301 domains match a company. Since 16 March 2026, 958 domains dropped the signal from every hostname we crawl.

0.18% of Customer Data Platform at TechnologyChecker.io, 29th of 68 rows, on the cleaned 553 domains. Segment leads with 25.45%, Adobe Experience Platform Identity Service has 24.87% and Lotame 8.38%. The share counts domains, not contracts or revenue.

In our Customer Data Platform table the largest rows are Segment (78,243 domains), Adobe Experience Platform Identity Service (76,447), Lotame (25,769) and RudderStack (21,179). Other customer data platforms we profile include mParticle (19,070) and Treasure Data (5,607). Tealium iQ isn't an alternative: it's the tag manager that sends AudienceStream its data.

By matched companies: the United States (144), Australia (38), the United Kingdom (15), the Netherlands (13) and Germany (12). The domain list behind Australia's figure includes 23 University of Melbourne faculty and centre sites, each listed as its own domain. The Dutch and German rows hold banks, insurers and telecoms such as ABN AMRO, a.s.r. and Deutsche Telekom.

Both ends. 34.25% of matched companies with a known size have more than 1,000 employees and 14.53% more than 10,000, while 1 to 10 employees is the largest single band at 23.53% and 11 to 50 adds 14.88%. The large end includes banks, insurers and retailers such as Travelers, ABN AMRO and CDW.

Mostly established. Of matched companies with a founding year, 26.67% started before 1960, the largest group, and 65.56% before 2000. The 2010s add 17.22% and the 2020s 6.11%. That matches a list of banks, insurers, hospital systems and long-standing retailers rather than young software firms.

On our data, a large, long-established company in retail, health care or insurance, in the US, Australia, the UK or the Netherlands, that already runs Tealium iQ (96.56% of domains) next to Google Tag Manager (70.52%) and often Adobe Analytics (18.08%). More than a third of matched companies have over 1,000 staff.

Yes, through AudienceStream. Tealium sells it as its customer data platform; its product page calls it the Tealium AudienceStream Customer Data Platform. The company also sells Tealium iQ, a tag manager. On our data the two go together: 96.56% of the 553 domains calling AudienceStream's servers also load Tealium iQ.

Collecting customer data from websites and apps and passing it to other tools. Tealium iQ manages the tags on a page, and its Collect tag sends events to Tealium's servers. There, AudienceStream builds visitor profiles and audiences, and Tealium's documentation describes a data layer enrichment feature that returns those profile attributes to the page.

Tealium iQ is the tag manager. It runs in the browser and loads utag.js from Tealium's tags.tiqcdn.com host. AudienceStream runs on Tealium's servers and turns the events iQ sends into visitor profiles and audiences. Our Tealium page counts iQ installs; this page counts sites calling tealiumiq.com. 96.56% of these domains also load iQ.

A site adds one script, utag.js, which loads from tags.tiqcdn.com under a path that names the Tealium account and profile, such as /utag/cdw/main/ on CDW's site. That file carries the tags and load rules set up in Tealium iQ and fires them on the page. When the Collect tag is on, events also go to Tealium's collect endpoint for AudienceStream.

The domain of Tealium's data collection servers. Tealium documents collect.tealiumiq.com as the endpoint that receives events, with regional versions such as collect-eu-west-1. On the sites we loaded on 14 November 2026, pages also called a visitor-service host on the same domain to fetch the visitor's profile. A call to tealiumiq.com is what puts a domain on this page.
