Designed Publicis Media's first data signal recovery solution.

Privacy changes across browsers and platforms were quietly eroding the signal media buying depends on. Attribution windows collapsed, audience match rates dropped, and campaign performance degraded without anyone being able to point to the cause.

• Built a server-to-server integration layer to reconstruct signal upstream of the browser.
• Integrated clean room technology so first-party data could be used at scale without breaching privacy boundaries.
• Packaged the whole stack as a client-facing solution with a clear ROI narrative, not just a technical fix, but a commercial position.

• 30% of lost audience signal recovered.
• Directly protected client media ROI through the peak of the privacy transition.
