Curated supply path

Most programmatic spend runs on inventory you don’t control

Open exchange buying gives you reach. It doesn’t give you much say over which domains your ads run on, which environments they appear in, or what you’re paying for.

AdChat’s curated supply path runs on a vetted list of around 5,000 publishers, with in-app inventory excluded by default. You get first-look auction access and a cleaner path from publisher to exchange to your DSP.

How it Works

How it works

Open exchange buying vs 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 around 5,000 publishers, screened for quality and fraud.

Every domain is vetted before it enters the path.

Deal floors set more predictable pricing and steadier delivery.

Attention filters, and optional contextual, point the deal toward inventory where the creative tends to perform.

More working media per dollar.

Higher viewability and attention.

Steadier delivery and pacing.

Stronger KPI efficiency in controlled tests.

What we tune

Six conditions we set and tune

AdChat curates the inventory and buying conditions that turn media dollars into high-quality impressions. Here’s what that means in practice.

Vetted publishers

Every domain in the path is screened for quality and fraud before it gets in. No made-for-advertising sites, no spoofing, no inventory you wouldn’t pick yourself. In-app is excluded by default, since most of it is rewarded or forced view that inflates viewability and VCR without signaling real intent.

Delivery conditions

Web only, no mobile app inventory unless you ask for it, plus device and browser filters so ads reach real users in real contexts. The web-only default is deliberate: in-app distorts the engagement signal the rest of the campaign depends on.

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 floors set more predictable CPMs and steadier pacing than open auction buying, where pricing and delivery swing on auction dynamics you don’t set.

Attention overlays

Third-party attention data (Lumen) applied to display and video, so the deal favors high-attention inventory. Pre-filtering at the SSP makes the DSP a better bidder: it only bids where the creative has the best chance to engage.

Contextual overlays

Optional contextual segments (Peer39) layered onto the deal when relevance matters. The page someone’s reading often signals intent better than a third-party audience does. Applied at the deal, so you pay the data CPM once instead of the vendor fee plus the DSP’s markup. Not every campaign needs them, but they’re there when targeting precision counts.

How we curate

Reach is easy. The right inventory takes curation.

Most curated supply strategies chase reach, spreading buying as wide as the inventory allows. We start from the brief instead. Every brief has its own definition of the right inventory, so we build the site list, format mix, and quality thresholds to match the campaign’s goals from day one, rather than taking whatever the open exchange or an “open” PMP happens to serve.

We work with premium SSPs that meet our standards for inventory quality, transparency, and fraud screening, and we build the deal structure, floor strategy, and enforcement on top of that. The curation is what keeps outcomes consistent across campaigns, not the size of the supply pool.
