Lotame

A leading independent data enrichment and identity resolution platform for the open web, now operating as part of Publicis Groupe's Epsilon division with a strong global footprint across publishers, agencies, and brands.

Lotame is a global data solutions company specializing in data enrichment, identity resolution, and audience activation for the open web. Founded in 2006, Lotame has built a reputation as one of the most sophisticated independent data platforms in the AdTech ecosystem, offering tools that help publishers monetize their audiences and enable marketers and agencies to reach relevant consumers at scale. In March 2025, Publicis Groupe announced the acquisition of Lotame, integrating it into its Epsilon data and technology division, with founder and CEO Andy Monfried retained to lead the business and the Lotame brand maintained as a distinct offering. Lotame's flagship technology, Spherical, serves as a unified data platform combining a Data Management Platform (DMP), Customer Data Platform (CDP), and identity resolution capabilities into a single solution. Its proprietary identity graph, Panorama ID, is a cookieless identity solution designed to help the industry navigate the deprecation of third-party cookies, enabling cross-device and cross-publisher audience matching without relying on legacy tracking infrastructure. This positions Lotame as a critical infrastructure provider for the post-cookie era of digital advertising. Operating across more than 100 countries, Lotame serves a diverse client base including publishers, brands, agencies, and data providers. Its integration into Epsilon strengthens its data assets and distribution capabilities, combining Lotame's open-web identity and enrichment expertise with Epsilon's first-party data and loyalty marketing strengths. Lotame competes with companies such as Nielsen, Oracle Data Cloud, LiveRamp, and Neustar in the broader data and identity resolution space.
