Acxiom

One of the largest and most established consumer data and identity resolution providers globally, serving Fortune 500 brands across multiple verticals

Acxiom is one of the world's largest and most established data and identity management companies, with roots dating back to 1969. The company provides enterprise brands with customer intelligence, data connectivity, and marketing solutions built on one of the industry's most comprehensive consumer data repositories — covering hundreds of millions of individuals across the globe. Acxiom's core offerings include identity resolution, data enrichment, audience segmentation, and data connectivity services that enable marketers to build accurate, privacy-compliant customer profiles across channels and devices. Acxiom operates as a subsidiary of IPG (Interpublic Group) following its acquisition in 2018, though it continues to function as an independent data services business serving clients outside the IPG network. Its flagship platform, Acxiom Real Identity, underpins many of its solutions by linking disparate data signals to persistent, people-based identities. The company also operates the LiveRamp data connectivity platform — though LiveRamp was spun off as a separate public company in 2018 when IPG acquired the Acxiom Marketing Solutions division. In the AdTech ecosystem, Acxiom occupies a foundational role as a data infrastructure provider. Its proprietary consumer data, identity graph, and data onboarding capabilities are used by major financial services, retail, automotive, and media companies to power personalization, customer acquisition, and measurement programs. Acxiom competes with Experian Marketing Services, Oracle Data Cloud, and Epsilon, and is widely regarded as one of the most trusted and scaled data providers in the industry.
