Publicis Media Strengthens Agency Leadership: Simon Kramm Named CEO of Spark Foundry; New Hire Joel Koch Named Chief Client Officer at Zenith

Spark Foundry, the world’s fastest-growing agency brand within the Publicis media universe, is expanding its leadership team in Germany. Effective immediately, Simon Kramm has assumed the role of CEO and is responsible for the agency’s client business and strategic direction.

Kramm joined Zenith—the largest media agency in the German Publicis network—two years ago from PIA Media. Until now, he has served as Chief Operating Officer, supporting Germany CEO Jennifer Andree. He will now bring his strengths—such as working with large teams and his specialized experience with clients in the beauty, retail, and entertainment industries—to his new role. He is supported in the management of Spark Foundry Germany by Managing Partners Carolin Hedderich, Sahra Farsi, and Ben Heuser. Kramm reports to Karin Ross, Chief Operating Officer of Publicis Groupe DACH and CEO of Publicis Connected Media DACH.  

Simon Kramm: “I am very grateful for the past few years, during which I was able to help shape Zenith’s strong growth alongside Jenny. Now I’m looking forward to bringing my experience to my new leadership role at Spark Foundry—working with incredibly exciting clients and potential new clients, and alongside an ambitious team that I’ve had the pleasure of working with on several Power of One projects.”  

At Zenith Germany, experienced agency executive Joel Koch is joining the leadership team led by Jennifer Andree (CEO). He will assume the role of Chief Client Officer in the coming months. With his proven expertise at the intersection of media, data, and technology, Koch will, for example, help make Publicis Connected Identity more accessible to advertisers and thereby create added value. Previously, Koch served as managing director of the agency PION3ERS, a spin-off of the Omnicom Media Group.

Jennifer Andree: “Last year, Zenith won the most new business in Germany, with billings exceeding 250 million euros. Simon played a key role in this success. He is now taking the next step in his career within Publicis Media. In Joel, I welcome an agency manager who has extensive experience in building and scaling agency structures, leading interdisciplinary teams, and developing new consulting and product approaches for modern brand communication. I’m very much looking forward to working with him and Zenith’s leadership team to support existing and new clients on their ongoing transformation journey.”

Joel Koch: “Today, agencies must excel technologically, organizationally, and creatively. With its integrated structure within Publicis Groupe Germany, I see Zenith as a pioneer for the entire market in precisely this regard. Its strong growth confirms the success of this approach. I look forward to working with Jenny and our colleagues to develop innovative organizational models that open up new business opportunities for clients and enable sustainable growth.”
