ArcSpan

ArcSpan helps publishers take full control of their audience data — turning fragmented first-party signals into a structured, monetisable asset.

Our platform, ArcSpan AMS, consolidates data from across a publisher's ecosystem — editorial behaviour, content consumption, registration data, contextual signals and more — into a unified audience layer. From there, publishers can build and activate high-value segments across programmatic channels, enriching bid requests and driving measurable CPM uplift without dependency on third-party cookies.

Key capabilities include:

• Identity Resolution — ingest and resolve hashed email and first-party IDs across environments, building a durable, cookieless identity spine
• Contextual Enrichment — apply ArcSpan's custom LLM-powered taxonomy to classify content at scale, enabling precise contextual targeting for buyers
• Audience Activation — push enriched segments directly to GAM, SSPs and DSPs, with flexible integration across the programmatic stack
• Audience Insights — give editorial, commercial and ad ops teams visibility into who their audiences are and how they behave, powering smarter packaging and direct sales
• Operational Efficiency — a single platform replaces multiple point solutions, reducing complexity and freeing up internal resource
  

ArcSpan is built for publishers, by people who understand the programmatic ecosystem — and is designed to integrate cleanly with existing tech stacks, including clean room environments and identity frameworks.
