Spark Engine transforms raw on-page data into high-value signals, deterministic, real-time, and impression-level. It surfaces dozens of metrics that prove the real quality of your inventory.
Exclusive supply chain access at scale
Pubstack’s unique position in the ad stack gives the Spark Engine visibility into sell-side signals. This allows us to uncover hidden value in a publisher’s inventory and surface it to buyers.
Real-time supply packaging
The Spark Engine package your inventory with buyer-relevant signals in real time. Ensuring faster, broader exposure and better performance in open auctions and curated deals.
Built with the buy-side in mind
Our Engine is co-designed with buyers; it continuously learns what the buy-side seek and adapts in real time, unlocking exclusive campaigns and higher revenue.
In traditional programmatic, buyers see only basic information: domain, ad slot, device, user ID. But that’s just the surface.
Signals go deeper at scale.
Signals are real-time data points extracted directly from the page that reveal the true quality of an impression.
