Radio attribution just became real.
For the first time, you can know exactly which listeners heard a sponsor spot — and deliver them an experience the moment they did. Not 48 hours later. Within 30 seconds.
Here's how a sponsor campaign works with Phantone.
- 01
The radio network watermarks the sponsor spot in their ad management system before it goes to air. AM, FM, streaming, or podcast — all supported.
- 02
The spot plays during morning drive. 2 million listeners across the country hear it through their car radios, phone speakers, smart speakers, and earbuds.
- 03
Every listener with the station's app, the sponsor's brand app, or a partner app hears the signal decoded in real time. The experience fires within 500ms of the spot ending.
- 04
The sponsor sees verified listener counts — not Arbitron estimates — with creative-level attribution, DMA-level geography, and real-time delivery.
- 05
The station delivers a sponsor report with cryptographically verified impression counts. The conversation about reach moves from methodology to evidence.
What the listener experiences.
Appears on the listener's phone 30 seconds after the spot. Only listeners who heard it qualify.
