We were founded in 2017 to develop identity solutions for digital advertising. Our work focuses on identity, GDPR, privacy, and addressability.

Our Adaptive Identity technology helps solve identity challenges in digital advertising by combining privacy with addressability. It learns and adapts to recognize users across different websites, devices, and channels, creating a scalable identity framework from fragmented signals.

We help media owners earn more revenue, advertisers get measurable results, and platforms maximize their data and inventory value. We work with media owners, AdTech platforms, and media buyers across the digital advertising ecosystem. In 2025, we acquired TrueData to expand our U.S. operations and improve our offerings.

Our mission is to support a sustainable digital economy, ensuring content and services are accessible and privacy-safe.

Our vision is to become the leading global identity provider for addressable and measurable advertising.
