From discovery to decision: How Reddit drives real business outcomes [ENG]

Discovery has fundamentally changed. In a fragmented, privacy-first landscape, visibility is no longer just about reach, it’s about being trusted and chosen. As traditional signals weaken and AI reshapes how people search, consumers are becoming more deliberate: actively researching, comparing, and validating before making decisions.

In this session, Bella Jagger, Senior Client Partner at Reddit and Peter Mittermayer Team Lead LCS AT/CH/BE and Reddit Advertising AT/BE at Aleph explore what this means for advertisers today. Drawing on real campaign examples, she unpacks the growing gap between influence and decision-making and the role of the “validation layer,” where conversations and communities drive action.

For marketers, the opportunity is clear: show up in high-intent moments, build strategies that earn trust, and turn that intent into measurable outcomes.
