LiveRamp Holdings, Inc.
LiveRamp · RAMP · San Francisco, California
LiveRamp (NYSE: RAMP) is the publicly traded data collaboration and identity infrastructure company spun out of Acxiom in 2018, anchoring the post-cookie addressable stack with RampID, ATS, and the Habu clean room.
LiveRamp is the public-company anchor of the independent identity stack. RampID is the connective tissue that lets advertisers, publishers, and measurement partners reconcile audiences without third-party cookies; ATS is the publisher-side embed that authenticates the impression at the source; and Habu, acquired in early 2024, extended the company into the data clean room layer where walled gardens and brand first-party data actually meet.
The corporate history matters for understanding the competitive landscape: LiveRamp and Acxiom were the same company until October 2018, when Interpublic Group bought Acxiom’s Marketing Solutions business for $2.3 billion. The remaining public entity renamed itself LiveRamp Holdings and kept the ticker. That makes Acxiom — now an IPG/Omnicom asset post the 2024–2025 holdco merger — the most consequential adjacency in any LiveRamp competitive read, alongside Epsilon under Publicis and a thinner ring of independent ID players including ID5, The Trade Desk’s UID2 consortium, and ad-tech-side identity graphs.
