Kellanova Taps Clean Room Data and AI to Enable Real-Time Personalization

Kellanova is pushing the frontier of precision marketing, piloting a clean room and generative AI integration to deliver real-time, privacy-safe consumer personalization at scale.

The pilot involved using clean room environments — secure digital spaces that allow brands to match their first-party data with retailer or partner data without exposing individual identities. Layering generative AI on top enabled Kellanova to produce dynamic content and offers tailored to specific audience segments in real time.

The approach allowed Kellanova to test personalized messaging and promotions based on where consumers are in their purchasing journey — while maintaining full compliance with data privacy regulations. The pilot also uncovered opportunities to streamline internal collaboration between marketing, data science, and retail partners.

The result: higher engagement, stronger conversion potential, and a blueprint for scaling personalization that is both precise and privacy-forward.
