SIGNAL TAXONOMY

Signals that arrive in the bid request

Every impression carries a proprietary signal payload that varies by supply channel. These are not inferred from third-party data — they are observed directly from the supply environment at the moment of impression.

SUPPLY-SIDE TRUTH

Signal at the point of impression

Other platforms proxy conversational intent from opt-in app data aggregated, delayed, cookie-dependent. Panxo captures signals at the point of impression: real-time, deterministic, and native to the inventory.


Observed, not modeled

Signals are captured at the moment of impression — real-time, deterministic, not probabilistic

No cookie matching required

Intent signals are inherent to the impression context — no user-level matching needed

Privacy-durable architecture

Zero PII, zero fingerprinting, zero third-party cookies. IAB TCF 2.2, GDPR, CCPA compliant
