Most programmatic spend runs on inventory you don’t control
Open exchange buying gives you reach. It doesn’t give you control over which domains your ads run on, which environments they appear in, or what you’re actually paying for.
AdChat’s curated supply path runs on a curated list of ~5,000 carefully vetted premium publishers. The result is more premium inventory, more predictable economics, and stronger campaign performance.
The difference between open exchange buying and a curated supply path
Open Exchange
Ads compete in auctions across millions of domains, most of which aren’t vetted.
You can’t always see where your ads ran or why performance varied.
Buying conditions shift based on uncontrollable auction dynamics.
Viewability and delivery are inconsistent flight to flight.
Curated Supply Path
Ads run on a hand-curated list of ~5,000 premium, fraud-free publishers.
Every domain is vetted for quality before it enters the path.
Deal floor strategy locks in predictable pricing and stable delivery.
High-attention and optional contextual filters ensure ads appear where they’re most likely to perform.
More premium reach per dollar.
Higher viewability and attention.
More stable delivery and pacing.
Stronger KPI efficiency.
What We Control
Six conditions set before your campaign runs
AdChat curates the inventory and buying conditions that turn media dollars into high-quality impressions. Here’s what that means in practice.
Premium inventory
Every publisher and domain in the path is vetted and fraud-free. No made-for-advertising sites, no domain spoofing, no inventory you wouldn’t choose yourself.
Delivery conditions
We filter by environment (web only, no mobile app inventory unless specified) and apply device and browser filters to ensure ads reach real users in real contexts.
Quality thresholds
Viewability minimums are set and enforced, not just reported. If inventory doesn’t meet the threshold, it doesn’t enter the path.
Economic controls
Deal floor strategy balances efficiency and delivery stability. You get predictable CPMs and consistent pacing rather than the volatility that comes with open auction buying.
Performance overlays
Third-party high-attention audience filters applied to display and video inventory. Ads run where attention is highest, not just where impressions are cheapest.
Contextual overlays
Optional interest-based contextual audience segments that can be layered onto the deal for additional relevance. Not every campaign needs them, but they’re available when targeting precision matters.
What It Delivers
Better inventory conditions produce better campaign outcomes
The benefits of the curated supply path show up differently depending on campaign goals. Here’s what clients consistently see.
More efficient CPM and eCPM
Every publisher and domain in the path is vetted and fraud-free. No made-for-advertising sites, no domain spoofing, no inventory you wouldn’t choose yourself.
Higher viewability and active attention
Enforced viewability thresholds and high-attention filters mean your ads are actually seen. Not just reported as viewable, actually seen.
More stable delivery and pacing
Predictable deal economics mean campaigns deliver consistently throughout the flight without the pacing volatility that comes with open auction dynamics.
Better KPI efficiency
Performance varies by campaign goal, but premium inventory consistently produces stronger results than open exchange buying across awareness, consideration, and conversion objectives.
Stronger video view efficiency
In premium environments, viewability and attention uplift combine to improve effective CPV. Your video assets reach the open web at display CPMs, on inventory you actually control, not wherever the open exchange sends them.
MFA-free and fraud-free by design
Every publisher in the path is vetted. Made-for-advertising sites and fraudulent inventory are excluded before the deal is set up, not filtered out after the fact.
Built With Index Exchange
We work with one SSP because quality doesn’t scale by adding more
Most curated supply strategies spread buying across multiple SSPs to maximize reach. We work exclusively with Index Exchange, and that’s intentional. Index Exchange operates one of the largest premium publisher networks in the world. Their inventory quality standards, transparency infrastructure, and fraud prevention protocols are what make the curated path work. Adding more SSPs would add volume. It wouldn’t add quality.
We build our deal structure, floor strategy, and quality enforcement to deliver consistent outcomes across campaigns, rather than variable results that depend on which SSP won a given auction.
Premium publisher network, fraud-free by design.
Full supply path transparency from publisher to impression.
Enforced viewability and quality thresholds at the deal level.
Consistent outcomes across campaigns and markets.
Extending the Supply Path
Add an audience intelligence layer to your Deal ID
MixBright is our research platform that generates brand, category, and audience research and turns the findings into clear, structured outputs. Those outputs can be mapped to contextual targeting segments and applied directly to an AdChat PMP Deal ID.
For campaigns where audience relevance matters as much as inventory quality, this gives you a supply path that’s curated for both. It’s an optional layer, not a requirement. Most large agency clients have their own planning infrastructure and targeting methodologies. But for teams looking for a sharper starting point, MixBright can provide it.
