About PerfxAd

Mission

PerfxAd is an independent, bilingual publication covering structural shifts in digital advertising and marketing technology. We observe the ecosystem — buy-side and sell-side, programmatic and walled-garden, global and local — and report what we find with source-driven rigor.

We do not sell products, services, or leads. We do not take sides. Our only obligation is to our readers: practitioners, researchers, and decision-makers who need accurate, timely, and contextualized information about the ad industry.
