We are thrilled to announce that Julien Mosse has joined Refinery89 as our new Chief Revenue Officer. Julien will lead our global revenue growth and international expansion across key European and Latin American markets.
In his role, Julien will oversee our Publishers, Brands & Agencies, AdTech Partnerships, and Marketing divisions, focusing on revenue growth opportunities in line with our vision to expand into high-value markets.
Julien’s career has been defined by scaling high-growth digital advertising organizations and driving profitability, including leading global operations at Ligatus and then Outbrain (now Teads), as well as pursuing his entrepreneurial side as the founder of Edisound, a pioneer in podcast distribution. He brings deep expertise in building cross-border sales organizations, strategic M&A, tech partnerships, and delivering performance across complex media landscapes.
“I am incredibly proud to partner with our founders Hugo, Rob, and our investors at Capital D, as we embark on Refinery89’s next chapter. The amazing vibes and deep talent within the current team are the perfect foundation for the rapid international expansion we are now accelerating.
What truly sets us apart in this consolidating market is the sheer solidity and power of our AdTech stack, which allows us to deliver unparalleled performance and transparency. With our premium exclusive inventory and strong institutional backing, the potential for both organic growth and strategic M&A is immense. I look forward to driving this vision forward and cementing Refinery89’s position as the definitive global partner for premium publishers and brands.” – shares Julien.
A new phase of global growth for Refinery89
Over the past few years, we have executed an ambitious roadmap to become the leading independent publisher network in Europe and LATAM. This growth is supported by a reinforced C-suite: after welcoming our new CFO, Rens Koning, in mid-2025 to steer financial scaling, Julien’s arrival as CRO marks a new era of market expansion. Together with our teams, we are accelerating our global footprint, deepening technological partnerships, and scaling innovative solutions for publishers and advertisers in a consolidating global market.
“Refinery89 is built to scale, and Julien knows how to scale,” said Hugo Welkers, CEO of Refinery89.
“Julien’s appointment is an important step in our global growth strategy. As we enter a decisive phase of international expansion, his proven ability to scale revenue, build high-performing commercial teams across borders, and navigate the complexities of both Publisher and Brand & Agency environments makes him the ideal leader to accelerate our growth across Europe, LATAM, and other premium markets worldwide. Besides his impressive track record, Julien is just a great person to work with both personally and professionally, so there was this immediate connection!”
As a Google Certified Publishing Partner, we remain highly dedicated to meeting top industry standards. We look forward to continuing to build strong relationships with both web and in-app digital publishers, while providing brands with exclusive access to relevant audiences through premium tech and groundbreaking frameworks like our Brand Building Outcome solution, designed to enhance campaign impact. Julien’s ambition further reinforces our commitment at Refinery89 to delivering high-quality, innovative, and scalable solutions for our clients while driving revenue growth.
