Co-Founder
Kampart
Digital communications agency in Stuttgart: brand development, high-end campaigns, and media production – for clients including Hansgrohe and Otto/Leger Home.
Kampart was a digital communications agency based in Stuttgart that Marius Rieg co-founded in 2022; it operated until 2026. Its focus: building brands, conceiving campaigns, and producing media that moves people.
Its services ranged from high-end brand development and campaign concepts to website design and app development, AI-assisted image and video production, and software built with tools like Claude Code and Codex.
Projects included product presentations for Hansgrohe, the visual language for Leger Home by Otto, and standalone visual worlds such as the Stahlrenner road bike production. The experience from Kampart now feeds directly into Luftschloss and Gieske Studios.
