Case Study: Christie’s achieves precise in-market audience targeting and brand transformation with Quantcast's AI and machine learning

Christie’s transforms its 255-year-old brand with machine learning and AI

Christie’s, the 255‑year‑old global auction house, needed a way to connect with a small, international, high‑net‑worth clientele while preserving trust and privacy. Because each lot is unique and future offerings are unpredictable, the company required agile, targeted audience outreach that used its first‑party data thoughtfully rather than broadly.

Partnering with Quantcast, Christie’s adopted a privacy‑first strategy and leveraged the Quantcast Platform powered by Ara™ (AI and machine learning) to surface real‑time insights and identify niche, in‑market audiences. The approach enabled selective partner outreach, improved matching of bidders to relevant lots, enhanced client experience, and fed actionable insights back into social campaigns.
