Summary
Editor's update, October 2026: 19 Oct 2026 accuracy audit: retired Lightning Tag and Cartographer names removed, positioning updated for Publicis ownership.
A data collaboration platform, now part of Publicis Groupe as Epsilon Lotame, helping marketers and publishers enrich first-party audiences and activate segments across CTV and mobile without relying on third-party cookies.
Lotame, now branded Epsilon Lotame within Publicis Groupe, is a data collaboration platform serving marketers, agencies and publishers. It centres its value proposition on the Spherical platform, which connects, enriches and activates audience data, with cookieless addressability through Panorama ID and the Panorama Graph. By focusing on first-party data enrichment and second-party data sharing, it allows media owners to maintain high-value audience segments without third-party cookies.
The platform's primary strengths include its Revenue & Monetization tools for media owners and its integration with the Lotame Data Exchange (LDX) and curated marketplaces. AI and machine-learning modelling, including lookalikes, helps users discover new target audiences, and more than 100 connections, including The Trade Desk, Google Display & Video 360, Amazon, Roku, Snowflake and Tealium, support activation across CTV and other screens.
However, there are trade-offs to consider, most notably the reported sluggishness of the platform despite its simple user interface. The site now addresses marketers first, so publisher-specific tooling is less prominent than it once was, and it may not offer the breadth of generic enterprise features found in larger marketing clouds like Adobe. Additionally, the lack of transparent pricing means publishers must engage in custom negotiations to determine total cost.
