Every play, receipted.
Out-of-home has always asked buyers for trust. We’d rather hand you a receipt.
One counter, whoever fills the slot.
Our ad server injects its own signed impression trackers into every slot it serves — regardless of whose demand fills it. Direct buy, programmatic, house creative: the counting authority doesn’t change when the buyer does, so the numbers you’re quoted and the numbers you’re billed on come from the same counter.
A receipt, in the literal sense.
Delivered impressions generate play receipts signed with Ed25519 on our rails — which screen, when, which creative. A receipt is a few hundred bytes you can store, forward, or drop into an audit, and the signature travels with it.
Verification doesn’t go through us. Receipts check out against our public key set — a JWKS anyone can fetch — so you, your client, or their auditor can verify a play without asking our permission.
Receipts cover the measured portion of delivery.
Where our sensing and signing stack runs, plays come back signed — and any receipt can be checked against the public key set without asking us.
