The result to aim for
For Westfield Days, Unibail-Rodamco-Westfield has integrated AI into commercial real estate: connected mirrors to test makeup and futuristic outfits generated by AI, with 500,000 visitors to Europe.
What was done
The Hub La Poste (3 December 2025), interview with Tristan Ehringer. 900 million visits per year, about 60 centres. The visuals of the international campaign (Rosa Paris) are displayed by the AI according to the markets (example: a fashionista in Paris is not the same in Saudi Arabia); On average 800 prompts per visual. Westfield Days: first edition with AI, "instagrammable" experiences. Other brick, non-generative: Digeiz analyzes anonymized video streams (RGPD). Mantra: "IA is never stronger than when it is driven by humans."
