Pubstack, a privately owned company headquartered in France, was founded in 2018. The company, which employs approximately 50 people, specializes in advertisement monitoring and analytics solutions for publishers, primarily focusing on RTB and programmatic technologies.
On September 17, 2026, Pubstack appointed Yann Stadnicki, a technology leader with expertise in AI machine learning and large-scale systems from Microsoft Research and Criteo, as its chief technology officer (CTO). This appointment aims to strengthen the company's leadership as it enters a new phase of technology and international growth, particularly to accelerate its "Spark" product, central to its Supply Intelligence vision. Previously, on May 6, 2026, Pubstack released its State of Programmatic Q1 2026 EU5 Benchmark. The report revealed a highly fragmented European programmatic market, noting that UK publishers experienced significant volume pressure while the price per impression remained resilient.
