Marketers are done using incomplete data, duplicated IDs or hashed emails, and they’re quickly shifting towards the next wave of efficient data collaboration and privacy guarantees. Defensible AI will need accurate and private seed data. We are the enablers of that transition for publisher and brand identity, enabling them to finally unify and see 100% of their site visitors with accuracy, compliance and ownership.

AdFixus provides you the critical ingredient - a stable and truly durable ID. We’re the pioneer of federated anonymous identity, enabling businesses to build out and transact securely on a cross domain, deterministic and anonymous ID. It’s yours to own and securely shareable with your data collaborators.

Rebuilding your tech stack beyond 2025 requires a true defensible USP beyond open exchange, cohorts, contextual or AI tools. The only guaranteed answer is to own your anonymous user data and create 100% addressability from it. One source of truth in your stack puts open web publishers on par with walled gardens to build platinum-tier ad products that deliver scale, accuracy and user privacy.

All accurately and securely.

Audience quality
“What we saw using the AdFixus platform and our cookie form is that traffic from a number of sources generated a large volume of IDs," he continues. "This latest release of the AdFixus Platform reduced the number of unwanted [ghost] profiles by an additional 20 per cent, greatly enhancing the quality of Carsales’ audiences.

Cohort visibility
"In the past six weeks, deploying AdFixus has allowed us to gain insights on nearly 600,000 unique 7News.com.au browsers, with many coming from Safari, or social referrals which [previously] meant little to zero insight – simply put, a blind cookie we knew nothing about. Now we can drop them into cohorts."

User insight
“SATC uses AdFixus to create an anonymous, privacy compliant identifier called the SATC ID which is assigned to users of consumer facing SATC websites who consent to the use of cookies. The identifier sits in a durable first party cookie which persists across our various domains and has resulted in us having a much more accurate picture of our users’ behaviour across our websites. This has led to a better understanding of our users’ online customer journey, reduced the time to statistical significance for our on-site experiments, and allowed us to deliver more relevant digital experiences to users considering a South Australian holiday.”

User recognition
“With third-party cookies gone, we had lost the ability to clearly distinguish new visitors from returning policyholders. AdFixus ID gave us that visibility back. Now we can accurately track and understand the behaviors of new versus returning users, which has been critical for how we shape acquisition and retention strategies.”
