AdXact, AdXcelerant’s demand-side platform (DSP), today (15th October, 2026) announced a partnership with VIOOH, the leading global premium digital out-of-home (DOOH) supply-side platform (SSP). The integration gives AdXact advertisers programmatic access to VIOOH’s DOOH inventory, while bringing additional demand to VIOOH and its media owners.

The partnership, which aims to make programmatic DOOH more accessible to media agencies and advertisers, marks a significant expansion of the inventory available through AdXact’s DSP. By accessing VIOOH inventory through AdXact, advertisers can manage DOOH within the same platform they use for their other campaigns, making it simpler to make strategic decisions and optimise performance.

For VIOOH, the connection creates a new channel for advertiser demand, bringing its inventory to AdXact’s buyers and expanding opportunities for its media owners. Key markets for the partnership include the US, EMEA, LATAM, and global airports.

"This partnership represents another exciting step in our vision for making premium digital out-of-home more accessible, flexible, and connected to the broader advertising ecosystem," said Dan Ryan, CEO of AdXact. "By integrating VIOOH’s premium inventory into our DSP, we’re giving advertisers more opportunities to reach audiences in meaningful moments, while opening new pathways for demand to reach VIOOH’s media owners. We see tremendous potential in what we can build together as programmatic DOOH continues to evolve."

"We’re delighted to partner with AdXact and bring VIOOH’s premium digital out-of-home inventory to its advertisers,” said Frances McCann, director of DSP partnerships, Global at VIOOH. "This integration opens a valuable new channel of demand for our media owners, while giving AdXact’s buyers simple, programmatic access to high-traffic screens that reach audiences on the go. Together, we’re making DOOH easier to plan, buy, and include alongside the rest of a campaign, and helping more advertisers unlock the impact of the channel."

Programmatic DOOH can be used as a standalone solution or as part of a wider multichannel campaign. It gives advertisers a brand-safe, high-impact way to reach audiences in the real world, with the flexibility to adjust campaigns quickly and the transparency that comes with programmatic buying. 

The integration is live and available now.
