Aidem

Niche privacy-first programmatic marketplace targeting European publishers and advertisers seeking cookieless, GDPR-compliant programmatic solutions

Aidem is a programmatic advertising marketplace founded in 2022, purpose-built for a cookieless, identifier-free advertising ecosystem. The platform connects publishers and advertisers through contextual and semantic targeting signals rather than personal data, making it fully compliant with GDPR and other privacy regulations by design rather than by adaptation. Aidem positions itself as a sustainable alternative to legacy programmatic infrastructure that relies on third-party cookies or device identifiers. The company primarily serves European publishers and advertisers who require privacy-compliant programmatic solutions, though its architecture is relevant globally as third-party cookie deprecation accelerates. Aidem's marketplace operates as a supply-side and demand-side intermediary, enabling monetisation and media buying without the consent management complexity typically associated with behavioural targeting. Its contextual engine analyses page-level content to match relevant advertising without profiling individual users. Aidem occupies a niche but growing segment of the programmatic market, competing with other privacy-centric or contextual advertising platforms. Its founding timing — coinciding with intensifying regulatory pressure and Google's cookie deprecation timeline — positions it as part of a broader industry shift toward privacy-preserving advertising infrastructure. The company is relatively early-stage and has a lean profile consistent with a startup operating in the European AdTech space.
