Valarian

Valarian builds infrastructure for organisations operating in high-trust, high-stakes environments. Our core product, ACRA, is a secure, compartmentalised backbone designed to run and protect mission-critical applications — now proven at the edge in portable GPU clusters as well as in the cloud and on-premise. We developed ACRA when existing infrastructure failed to meet real-world risk — where segmentation breaks down, audit trails disappear, and lateral movement cannot be contained. Valarian is a UK-founded and UK-led company, and backed by leading defence and national security investors. We are a homegrown team with backgrounds across defence, secure communications, high-assurance systems, and enterprise software — engineers and operators who have worked in environments where a lost signal or a missed audit can carry real consequences. We design like users because we’ve been them.

pubX

An End-to-End Advertising Marketplace. Built on Trust. pubX connects publishers and advertisers through a transparent, data-driven marketplace built to deliver more efficient, higher-value programmatic outcomes for both sides. We use Agentic technology to drive real results at scale and ensure maximum active media is delivered to campaigns. Trusted for 5 years to build and deploy machine learning technology for publishers at scale, we've built the publisher relationships that make this possible. That foundation is what separates us from the experimental - our technology is battle-tested, our data is real, and our results speak for themselves. For publishers: first-party data becomes a competitive advantage, with sales agents negotiating the best value for every impression. For advertisers and agencies: buying agents autonomously evaluate premium inventory, build high-performing segments, and activate campaigns - powered by data unavailable through traditional programmatic. One platform. Two powerful solutions. Full transparency on both sides. A founding member of AgenticAdvertising.org.
