Johannes Leonardo was created with the belief that we are only at the beginning of a fundamental shift in the way consumers will ultimately engage with brands. Technology is exponentially changing our world and as a result media no longer controls the conversation. Consumers do. Consumers who will only continue to become more empowered. More in control of what they see, more able to spread ideas and bring their own voice to a brand’s message.

Johannes Leonardo optimizes all we do against them. There will always be new media. There will always be new technology. But there is only one medium. The consumer is the medium. Johannes Leonardo empowers and liberates them through our ideas.



Jan Jacobs and Leo Premutico

Co-Founders and Chief Creative Officers

In 2007, Jan and Leo co-founded Johannes Leonardo based on the philosophy that the consumer has become the new medium. In the ten years since co-founding the agency, they’ve created transformative brand ideas for some of the world’s most influential companies. Their work for Google helped to usher traditional storytelling into the modern age and resulted in the mobile Grand Prix at the Cannes advertising festival. They re-positioned adidas Originals into challengers of the status quo with their strikethru campaign which has contributed to an unprecedented turnaround for the company, and was awarded the 2017 Entertainment for Music Grand Prix at the same festival. While the duo’s Live Mutual platform has not only allowed Mass Mutual to rise above the category and influence culture, it is also influencing the way the organization operates.

In addition to winning every industry accolade, the pair have twice been featured as one of Creativity's 50 most influential creative people. Prior to launching Johannes Leonardo, they served as ECDs at Saatchi & Saatchi New York where their work on P&G’s Tide’s 2008 Super Bowl spot helped the commercial be named one of the top 20 Super Bowl ads of all time by AdAge. In 2018, Johannes Leonardo was named to AdAge’s Agency A-List, a ranking of the nation’s top 10 advertising agencies.
