Klaus Nadler becomes Chief Sales Officer at Zattoo
Starting in 2025, Klaus Nadler will join Zattoo’s management team as Chief Sales Officer. With his many years of experience leading agencies and marketing firms, as well as his extensive expertise in digital advertising, he is expected to further build on the streaming provider’s strengths in digital advertising. He succeeds Oliver Knappmann, who was responsible for Zattoo’s advertising division.

As Chief Sales Officer, Nadler will play a key role in strengthening Zattoo's advertising marketing, as the TV streaming provider writes in a press release. In his position, he will drive the development of innovative, data-based advertising formats and advertising strategies, tap into new revenue potential in the area of connected TV and ensure that the advertising solutions meet the requirements and expectations of stakeholders. As CSO, he is also responsible for the management and strategic control of all advertising-related teams at Zattoo. This includes the Ad Sales team in Switzerland and Germany, Ad Operations & Programmatic Management and Key Account Management.
Nadler has more than 25 years of experience in strategic leadership, digitalization and business development of media and communications companies. Since October 2023, he has been a Partner at Leader Selection Executive Search, specializing in the placement of leaders in the fields of digital transformation, technology and media. Previously, he was Lead Partner Digital Marketing at Deloitte, where he and his team developed and implemented innovative strategies for data-driven marketing and media solutions.
From 2017 to 2021, he was CEO of Carat Germany. Further stations in his career include leading positions at the Goldbach Group, where he was responsible for the digital focus and market entry in Germany, as CEO of GroupM Services in Switzerland and at IP Deutschland (RTL Group) and Versatel.
"I am looking forward to further advancing Zattoo's advertising strategy and developing innovative solutions for our advertising partners together with our highly qualified team," the new CSO is quoted as saying. "By focusing on data-driven advertising formats and concentrating on the needs of our customers and users, we will position Zattoo as the leading partner for digital advertising in the DACH region."
Zattoo justifies Oliver Knappmann's departure with a realignment of the position as part of the ongoing strategy process. "I would like to thank Oliver Knappmann for his great contribution to the development and successful establishment of our advertising business and for the introduction of numerous innovative advertising formats, in particular Dynamic Ad Substitution. He was an extremely valued member of the management team and played a key role in shaping Zattoo for more than a decade," said Zattoo CEO Roger Elsener.
