Overview
Addingwell is a server-side Google Tag Manager (sGTM) infrastructure platform designed for digital marketing, web analytics, and DevOps teams. Following its acquisition by Didomi in 2025, the platform pairs server-side tag hosting with consent management, enabling organizations to collect first-party event data while maintaining regulatory compliance.
The platform helps marketers recover conversion signals that are typically blocked by ad blockers, browser restrictions, and third-party cookie deprecation. By processing tracking requests on multi-region cloud infrastructure, Addingwell reduces client-side script execution to improve website loading speeds and feed accurate event streams into ad platform algorithms like Google Performance Max and Meta Advantage+.
