Kleinanzeigen's 2025 “Green Sunday” campaign centres on the coined term “GRÜNSTIG” (green + good value), positioning secondhand shopping as a sustainable and budget-friendly counterpoint to Black Friday. 
The campaign was developed by agency "The Goodwins" who describe it as a multi-channel rollout across TV, online video, display, and social. The campaign’s film was produced by berlin based AI Studio TEKTITE under the direction of Hauke Hilberg, with “green production” as a center of the agencies positioning explicitly highlighted as part of the approach.
The project's approach included AI casting (even with casting videos to align early on characters) and AI styling as part of the workflow.
All frames where AI generated, and polished in post, the sound layer was classically produced by berlin based sound studio "The Fridge". For more insights and the film watch Hauke's case study keynote in the Commercial Content Club.
