Johannes Leonardo

Independent, creatively-led agency competing with both independent shops and holding company networks for global brand accounts

Johannes Leonardo is an independent creative advertising agency headquartered in New York City, founded in 2007 by Jan Jacobs and Leo Premutico. The agency has built a reputation for producing culturally impactful, idea-led creative work that spans brand strategy, advertising campaigns, digital content, and experiential marketing. Its client roster has included major global brands such as Adidas, Volkswagen, Google, Stella Artois, and Diesel, among others. The agency operates as a full-service creative shop with a philosophy centered on creating work that transcends traditional advertising and enters broader cultural conversations. Johannes Leonardo has been recognized consistently in industry award shows including Cannes Lions, The One Show, and D&AD, cementing its reputation as one of the more creatively ambitious independent agencies in the United States. While not a technology company in the traditional AdTech sense, Johannes Leonardo operates within the broader advertising ecosystem as a creative agency partner. It does not offer SaaS products or programmatic technology platforms, but rather serves as a strategic and creative partner to brands seeking differentiated, high-impact advertising. Its independence from holding company structures is a key part of its identity and value proposition to clients seeking agile, senior-led creative talent.
