ArcSpan

Founded in 2020, ArcSpan is a B2B enterprise-level customer data platform (CDP) and audience monetization platform. The platform is a sell-side platform where ad publishers can gain access to first-party audience data that leverages deterministic and probabilistic AI models to build and dynamically update relevant audiences. The platform has monetization solutions for both onsite and offsite advertising across a variety of digital channels.   

The firm was established by leaders in the digital media publishing space, hailing from firms such as Accordant Media, Dentsu, NewsCorp, and Beeswax. It claims that its platform is purpose-built for ad publishers, designed to address the challenges of customer identity resolution brought about by changes in privacy regulations. The firm claims that its platform can boost addressable audience revenue by 30%–200%, a 2x–3x boost to addressable audience sizes and a 3x–4x increase in ad engagement. 

In October 2021, ArcSpan Media launched “Audience Engine,” an omnichannel audience monetization platform purpose-built for publishers. In May 2023, the firm launched ArcSpan AMS, an audience monetization system aimed at helping first-party publishers maximize their audience monetization strategies.
