Core pillars

Three problems buyers are solving for.
Three things HBX was built to do.

Transparency

Every signal visible. Every path validated.
  • Human MediaGuard scans 100% of bid requests — no sampling
  • FraudSensor scans 100% of impressions
  • Verified supply paths, end to end

Granularity

Target anything. Report on everything.
  • Any oRTB 2.6 signal targetable, down to show level
  • Near real-time reporting across every dimension
  • Custom metrics and formulas built to your spec

Efficiency

Every request earns its place.
  • Atomic QPS counting — no overages, no silent throttling
  • Traffic shaping applied to every bidder
  • rCPM controls and multi-armed bandit optimization
Inventory

One exchange. Every screen and every speaker.
