Advertisers interested in a tool to unify user identification, optimize cross-device targeting, and measure performance across digital channels

About ID5

ID5 offers a privacy-first, adaptive universal identity platform built for the evolving landscape of digital advertising. Its core offering, the ID5 ID, is a persistent, encrypted identifier that leverages both deterministic and probabilistic signals to create durable, consent-aware user profiles across web, in-app, CTV, and audio environments. The ID5 Graph then intelligently connects those identifiers at individual and household levels, enabling cross-device targeting, frequency capping, and measurement across channels. Designed to be resilient to regulatory changes and third-party cookie deprecation, ID5’s machine learning technology adapts dynamically to signal loss and fragmentation, maintaining consistent identity resolution. It integrates with more than 100,000 media properties and major adtech systems, supporting publishers, SSPs, DSPs, and brands by increasing addressable audiences and improving campaign performance.
