The neutral, multi-DSP Supply-Side Platform built exclusively for in-store retail media. True RTB auctions across 35+ DSPs — delivering 30–80% CPM uplift versus waterfall models.
Programmatic DOOH (Digital Out-of-Home) advertising uses automated real-time bidding (RTB) auctions to buy and sell digital screen advertising inventory. Adflux's Supply-Side Platform (SSP) connects retail media screen networks to 35+ global demand-side platforms (DSPs) including The Trade Desk, Google DV360, and Xandr, enabling retailers to maximise revenue from every available impression.
Eight distinct advantages that make Adflux the programmatic SSP of choice for retail media network operators.
While most SSPs in DOOH connect to 3–6 DSPs, the Adflux Programmatic SSP connects to 35+ programmatic DSPs globally — including all major programmatic buyers, retail media DSPs, and performance-led demand sources.
All 35+ DSPs bid simultaneously in a true real-time auction — the highest bid always wins, driving CPM uplifts of 30–80% versus traditional waterfall models.

Every impression enters a live auction across all connected demand sources simultaneously — ensuring the highest clearing price for every ad slot.
Adflux SSP is specifically aligned to the targeting and compliance requirements of in-store retail environments across all major verticals.
A concise comparison for retail media monetisation and programmatic DOOH.
| Feature | Adflux SSP | Vistar | Broadsign | Hivestack |
|---|---|---|---|---|
| Auction Model | True RTB mediation across all connected DSPs → highest clearing price | Strong DSP/SSP RTB but vertically integrated | RTB via Reach + Place Exchange but within own ecosystem | Full-stack RTB, but with commercial conflicts across buy/sell/data |
| Multi-DSP Access | 35+ DSPs simultaneously, creating maximum competition | Broad DSP access but prioritises buyers within ecosystem | Broad DSP access but prioritises buyers within ecosystem | Broad DSP access but prioritises buyers within ecosystem |
| Conflicts of Interest | No owned media, no DSP bias, no CMS lock-in | Vertically integrated — natural incentives to optimise own stack | Vertically integrated — natural incentives to optimise own stack | Vertically integrated — natural incentives to optimise own stack |
| Retail Media Suitability | Purpose-built for in-store networks — CMS stays in control | Excellent demand pipes but less flexible, control shifts to platform | Excellent demand pipes but less flexible, control shifts to platform | Excellent demand pipes but less flexible, control shifts to platform |
| Commercial Transparency | Clear structure, no hidden margin stacking, higher retailer revenue | Standard SSP/DSP margin stack | Standard SSP/DSP margin stack | Standard SSP/DSP margin stack |
Adflux SSP delivers maximum monetisation through neutral, multi-DSP RTB auctions, while Vistar, Broadsign, and Hivestack offer strong demand but come with ecosystem lock-ins and commercial conflicts. For retailers who want to retain control of their CMS while maximising programmatic yield, Adflux SSP is the clear choice.
Dynamic floor pricing, deal type waterfall management, and real-time fill rate optimisation work together to maximise revenue across every impression opportunity.
