Conversant

A leading people-based personalization and performance advertising platform operating within Epsilon, known for its proprietary identity graph and cross-device targeting capabilities.

Conversant is a personalized digital advertising company that specializes in delivering individualized marketing experiences at scale. The platform combines a massive proprietary consumer data asset with advanced identity resolution technology to help brands reach specific individuals — not just audience segments — across devices, channels, and publishers. Conversant's core capabilities span affiliate marketing, personalized display advertising, email marketing, and cross-device identity matching, making it a comprehensive solution for performance-driven marketers seeking measurable outcomes. Conversant was formed through the 2014 merger of ValueClick and Commission Junction, rebranding the combined entity under the Conversant name. Shortly after, in late 2014, Conversant was acquired by Alliance Data Systems (ADS) for approximately $2.3 billion, integrating it into ADS's Epsilon marketing services division. This acquisition brought Conversant's identity graph and personalization technology together with Epsilon's loyalty data and CRM capabilities, significantly strengthening Epsilon's position in the data-driven marketing space. Within the AdTech ecosystem, Conversant is recognized for its people-based marketing approach, which predates the broader industry shift toward identity-based advertising. Its proprietary identity graph — built from billions of consumer transactions and behavioral signals — enables precise one-to-one personalization across the open web, making it a competitive alternative to walled-garden platforms. Conversant serves major enterprise brands across retail, financial services, travel, and automotive verticals, competing with platforms such as Criteo, LiveRamp, and The Trade Desk.
