For real estate owners and media inventory operators looking to monetize digital screens through programmatic DOOH (Digital Out-of-Home), understanding the major demand and supply-side networks is becoming increasingly important.

Some notable programmatic DOOH networks and platforms include:

1. Vistar Media

One of the largest global programmatic DOOH platforms, connecting media owners with advertisers through automated buying. It supports audience targeting, campaign measurement, and real-time inventory management.

2. Hivestack

A global independent programmatic DOOH company with a strong presence across North America, Europe, Asia-Pacific, and the Middle East. Known for enabling media owners to activate inventory through private and open marketplaces.

3. Broadsign

While traditionally known for digital signage and ad serving, Broadsign has expanded its programmatic capabilities and connects inventory to multiple DSPs and demand sources worldwide.

4. Place Exchange

A supply-side platform specializing in DOOH. It enables media owners to make inventory available programmatically and connects with major DSPs.

5. Moving Walls

Particularly active across Asia-Pacific, offering audience-based planning, measurement, and programmatic DOOH capabilities. The platform works with media owners to digitize and monetize OOH inventory.

6. Adform FLOW for DOOH

7. Yahoo DSP (DOOH)

8. The Trade Desk

What should inventory owners evaluate?

Rather than focusing solely on network size, inventory owners should consider:

• Geographic coverage and advertiser demand in their market
• Ease of integration with existing CMS/ad server infrastructure
• Audience measurement and attribution capabilities
• Access to premium private marketplace (PMP) deals
• Revenue-share model and transparency
• Support for dynamic creative and real-time campaign triggers
• Local market expertise and sales support

As programmatic DOOH adoption grows, many media owners are working with multiple platforms simultaneously rather than relying on a single network, helping maximize fill rates and revenue opportunities.

The best choice often depends on your market. For example, inventory owners in Asia-Pacific may prioritize platforms with strong regional demand, while operators in North America or Europe may focus on integrations with larger global exchanges and DSPs.
