Direct peers

• Hivestack: Hivestack is a direct competitor as a global programmatic DOOH supply-side and demand-side platform, offering ad-server technology, SSP capabilities, and DSP connections similar to VIOOH's Trading Manager, with overlapping integrations for media-owner inventory.
• Vistar Media: Vistar Media operates as a DOOH SSP powering programmatic trading of digital out-of-home inventory across media owners, directly comparable to VIOOH's marketplace role and serving the same buyer (DSP/agency) base.
• Place Exchange: Place Exchange is a programmatic DOOH marketplace/SSP that connects media owners with DSPs (including The Trade Desk), serving the same dual-sided audience as VIOOH with comparable real-time bidding and audience-targeting capabilities.
• Broadsign Reach: Broadsign Reach is Broadsign's DOOH SSP for programmatic buying of out-of-home inventory via DSPs, offering supply-side platform and yield-management capabilities that directly overlap with VIOOH's Trading Manager offering.

Broad incumbents

• JCDecaux: JCDecaux is the world's largest OOH media owner and VIOOH's flagship SSP partner covering 30,000+ screens; they share programmatic DOOH focus but JCDecaux operates an even broader media-owner and infrastructure portfolio spanning transit, street furniture, and billboards globally.
• Clear Channel Outdoor: Clear Channel Outdoor is a major global OOH media owner with operations spanning billboards, transit, and airports; while broader than a pure SSP, it competes at the supply-side platform layer for programmatic DOOH inventory and campaigns relevant to VIOOH's buyer base.
• Talon Outdoor: Talon is a global out-of-home agency with proprietary programmatic planning/trading platform (Talon Advance) that interfaces with multiple DOOH SSPs; it competes with VIOOH at the planning-and-buying layer for advertiser budgets in the same pDOOH ecosystem.
• Google Display & Video 360 (DV360): DV360 is a leading omnichannel DSP that integrates with VIOOH for programmatic DOOH buying; as a broader incumbent in digital advertising technology, it has the scale and product breadth to grow DOOH capabilities that intersect with VIOOH's marketplace.
• The Trade Desk: The Trade Desk is a major DSP that connects with VIOOH for programmatic DOOH inventory access; it operates across CTV, display, and OOH and could deepen its own OOH marketplace, making it both a partner and a competitive incumbent in the broader ad-tech stack.

Emerging players

• FRAMEN: FRAMEN is a German DOOH screen network and technology provider that integrates VIOOH's SSP into its inventory; it overlaps at the intersection of media ownership and programmatic aggregation, offering smaller but comparable marketplace capabilities in DACH.
