Matthias Koller becomes Co-CEO at Rosarot
Matthias Koller, the former CEO of Publicis Zurich, is joining the Zurich-based agency Rosarot. Among other things, he plans to strategically drive forward the agency’s campaigning and social media efforts.

Matthias Koller will join the owner-managed agency Rosarot as Co-CEO from June 2024. Together with founder René Karrer and as a member of the five-person management team, Koller will steer the fortunes of the agency in future.
Rosarot specializes in branding, campaigning, social media and performance. The independent agency has been in existence for almost 18 years and employs around 30 people. The portfolio consists of both small and large national and international clients from a wide range of industries.
As Co-CEO, Koller is to strategically drive forward the areas of campaigning and social media in particular and further shape the direction of the agency, the agency writes in a press release. His appointment completes the management team consisting of Nadine Ticozzelli, Michael Schmidt, Andreas Steiner and René Karrer.
Koller started his career 23 years ago as a trend scout before working for several years as a copywriter/concept developer and creative consultant. He joined Publicis Zurich 14 years ago as a consultant and worked his way through all hierarchical levels up to Managing Director. For the last eight years he has been a member of the Executive Board, and for the last two and a half years he has headed the agency as CEO.
"It was time for a change"
"I'm really looking forward to my new role and working with my talented colleagues at Rosarot," says Koller about his new role. "I'm particularly looking forward to the agile, fast and uncomplicated way of working in this creative environment. After 14 years at Stadelhoferstrasse, it was time for a change and I am convinced that the position at Rosarot suits me perfectly."
Rosarot founder and co-CEO René Karrer is also looking forward to working with Koller: "His extensive experience and passion for innovative communication will undoubtedly enrich Rosarot. Together we will continue the success story of our agency and set new standards."
