About WhoWhere
See: Who saw your campaign
Capturing attention out-of-home drives purchase and builds brands, 79% of those exposed take some form of action*. WhoWhere measures the real-world reach of your retail media, events spend or live brand experience, not just OOH posters. We also work with event organisers and transport operators on crowd measurement and public safety, using the latest sensing technology to deliver rigorous, reliable data.
*Outsmart, 2026
Prove: The uplift it drove
Proving ROI means going beyond footfall counts. Using geofencing we run control trials that compare in-store traffic among people exposed to your ad against a matched group who weren't. Isolating the true uplift your campaign delivered.
Act: Retarget to supercharge your spend
Take your campaign further by serving geotargeted ads to the mobiles of people already exposed to your OOH, event or experiential activity. Using Mobile Device IDs, we handle targeting, serving and impact measurement end-to-end. Delivering a closed loop between physical exposure and digital response.
