Didomi

Didomi builds a consent and preference management platform (CMP) that helps organizations collect, store, and prove user consent for data privacy regulations including GDPR, CCPA/CPRA, and comparable laws across dozens of jurisdictions. The platform covers consent collection across web banners, mobile SDKs, connected TV, and email, feeding a unified preference center where end users can manage their own choices in over 45 languages.

Didomi was among the first consent management vendors to achieve IAB Europe’s Transparency & Consent Framework (TCF) v2.0 certification, and it integrates with Google Consent Mode and other ad-tech consent signaling standards. That certification matters in a category where "compliant" is often asserted rather than demonstrated — TCF certification is independently auditable through IAB Europe’s own registry, giving privacy and legal teams a verifiable basis for their consent claims rather than a vendor’s word alone.

Paris-based and founded in 2017, Didomi has grown to roughly 165 employees and reports over 2,500 brand customers across 35+ countries, backed by a $40 million Series B round. The company competes in an increasingly crowded and commoditizing consent-management field against OneTrust, Cookiebot, Usercentrics, and others, differentiating primarily on multi-channel coverage (web, mobile, CTV) and European-first regulatory design.
