Overview
Didomi is a consent and preference management platform that helps organizations capture user consent, activate first-party data, and maintain compliance across global privacy regulations. It serves more than 2,000 clients across media and publishing, banking and finance, healthcare and pharmaceutical, retail and ecommerce, and gaming.
The core Consent Management Platform (CMP) supports GDPR, more than 20 US state privacy laws (CCPA/CPRA, VCDPA, CTDPA, CPA and others), Quebec Law 25 and LGPD, along with technical signal standards including IAB TCF v2.2, GPP, Google Consent Mode v2, Microsoft UET Consent Mode and AWS Consent Mode. Consent experiences are localized in more than 45 languages and unified across web, mobile app and connected TV. A separate Preference Management Platform collects zero- and first-party data across web, mobile, email and in-store touchpoints, and Advanced Compliance Monitoring scans sites for unauthorized trackers and generates audit reports.
Didomi also offers Addingwell by Didomi, a server-side tagging product that routes first-party data to protect it from ad and tracking blockers while preserving consent-backed transmission, and a Privacy Requests module that automates access, deletion and opt-out fulfillment. The company was founded in 2017 by CEO Romain Gauthier and is headquartered in Paris, France, and holds ISO/IEC 27001:2022 certification for its information security management system.
