ArcSpan Integrates First-id for Persistent Cookieless Publisher Identity
ArcSpan, an AI-powered audience monetization platform for premium publishers, announced a native integration with First-id, a persistent, deterministic identity solution adopted by over 35,000 media and advertiser sites across 101 countries. This integration allows publishers using First-id to resolve audience signals within ArcSpan AMS without custom integrations. Publishers can build, analyze, and activate first-party audiences across direct, programmatic, and data collaboration channels. The combined solution addresses the challenge of fragmented user identities by providing a persistent identifier that works without third-party cookies or logins, enabling improved audience continuity, deduplicated reach, and enhanced monetization opportunities. The integration is live and available to existing customers, supporting ArcSpan's expansion across EMEA.
