A privacy-first identity solution that creates unified, consented user profiles across platforms, cross-browser, and cross-device without third-party cookies, enabling accurate targeting and personalization while ensuring regulatory compliance.
Our proprietary Unified Identity is a privacy-first identity solution designed to create a consistent, secure view of users across platforms, devices, and ecosystems — without relying on third-party cookies. It enables organizations to recognize and engage users through a persistent, consented identity that respects data privacy standards and user choice.
By stitching together fragmented identifiers into a unified user profile, the system empowers more accurate targeting, personalization, and measurement across digital touchpoints. Built to support interoperability with leading adtech, martech, and data platforms, it ensures seamless integration and scalability.
With compliance at its core (GDPR, CCPA, and beyond), Unified Identity Management gives businesses the tools to build trusted relationships with users while maximizing addressability and long-term value.
We conducted benchmarking tests with an early client to evaluate two key aspects:
As shown in the following figure on the left, our Unified ID successfully identifies the same user across two different browsers (e.g., Chrome and Safari), in both standard and private browsing modes (Note: third-party cookies do not work in Safari and private modes).
The figure on the right compares the performance of our method against first-party cookies on the same device, tested on a real e-commerce website with over 1 million monthly visitors. The results show that our solution can reduce duplicate user profiles by approximately 15–20% per week — significantly lowering computational costs and increasing user engagement.
The table provides a theoretical comparison between our solution and two widely used alternatives in digital marketing. Four key properties are evaluated: (i) availability of hard-identifiable signals, (ii) ability to merge and deduplicate user profiles dynamically, (iii) support for anonymous users, and (iv) SDK size.
As shown on the table, our Unified ID performs comparably to state-of-the-art solutions, and even outperforms them in certain scenarios, such as private browsing mode and cross-browser identification. It’s important to note that solutions relying solely on first-party cookies are vulnerable to common user behaviours — like regularly clearing browsing history, which causes IDs to change frequently over time.
