Assertive Yield announced the appointment of Mathieu Gallienne as director of publisher development in France and Benelux. Mathieu will lead commercial strategy and regional growth initiatives, strengthening Assertive Yield’s presence across French-speaking Europe and the Benelux markets.

Mathieu brings deep ad tech and programmatic experience, with a record of building publisher relationships and accelerating revenue through data-driven monetisation solutions. In his new role, he will focus on expanding Assertive Yield’s market footprint, driving growth, and partnering with publishers to modernise their ad stacks.

"Publishers in France and Benelux are navigating the same stack complexity as everyone else — without the same level of local support," said Nils Lind, CEO of Assertive Yield. "Mathieu changes that. Deep regional relationships, strong technical grounding. Right person for the market."

Mathieu’s appointment follows the company’s strategic decision to expand its footprint across Europe and increase its presence in key markets.

Mathieu Gallienne, director of publisher development at Assertive Yield, commented: "I’m thrilled to join Assertive Yield at a time of strong product momentum. I look forward to working with publishers across France and the Benelux region to deliver measurable yield improvements and long-term technical partnership."
