First-ID

First-ID, a privately owned company headquartered in France, was founded in 2022 and operates with approximately 10 employees. The company reported $1.5M in revenue as of 2024. Specializing in data, targeting, and identity solutions, First-ID provides offerings designed for publishers navigating changes in advertising strategies due to the deprecation of third-party cookies and associated revenue impacts on Safari and Firefox environments. The company offers a cross-publisher first-party cookie solution that operates across all browsers, including Chrome, Safari, and Firefox, and various environments. This solution aims to enable publishers to regain control of their inventory through enhanced identification, making 100% of their audience cross-site addressable within the publisher's Data Management Platform (DMP) for both advertising and personalization. It allows publishers' campaigns to utilize their own data to target internet users across all browsers. The solution has undergone testing with brands from the Prisma Media group and Cerise Media, demonstrating its capability to improve identification for cookie-less inventories and support advertisers and agencies in identifying customers on media brands.
