Vistar Media
Leading programmatic digital out-of-home platform, bought by T-Mobile in 2025.
New York, USA · founded 2012 · vistarmedia.com
What Vistar Media does
Vistar Media runs a DSP and SSP for DOOH: digital billboards, screens in shops, gyms, airports and taxis. Advertisers can buy these screens automatically, targeted by time and location.
T-Mobile bought Vistar for about $600 million in early 2025, alongside location-data firm Blis, to build an advertising business around its mobile network data.
How it makes money
Fees on DOOH media bought and sold through its platforms (now within T-Mobile).
Where it meets invalid traffic
DOOH has unusual fraud risks such as screens that are off or unseen; Vistar uses screen and venue verification plus audience-measurement data.
