Measurement
Check the delivery yourself.
Every ad that plays here is counted in our wrapper and signed with our key, whoever filled it. Fetch the key, verify the signature, count the plays.
Where an audience comes from
A package ships when all three describe the same people.
Screens that seeOn-screen sensors read their own audience: venue, mood, cohort, age, gender, attire, what people are carrying, what they are doing, and whether they stopped. Thirteen dimensions, on our own inventory.
A national mobile panelObserved store visits at national scale, which is where a brand-visitation index like “people who go to Chipotle” comes from.
Our own device graphProximity signals are read at each screen, so an exposure is recorded where it happened rather than modelled afterwards. Identifiers are hashed with a rotating pepper.
What comes back
- Verified delivery
- A play counts when the screen was operational, at least 95% of the scheduled duration ran, and it passed general-invalid-traffic filtering.
- Proof of play
- Every impression we report is signed with Ed25519. Verify them yourself against our public key. No account needed.
- Reach and frequency
- Deduplicated unique devices, average frequency, and a DMA-matched control group built alongside the exposed set.
- Attention
- Measured per play and priced into the floor.
- Outcomes
- The control leg is standing. Connect a conversion source (AppsFlyer, Adjust, Kochava, GA4, Meta Ads, Google Ads or Shopify) and outcomes run against your own numbers. The full connector list.
- Brand safety
- Every creative reviewed against IAB content category, age rating and venue context before it can serve.
The full methodology
Public and versioned: the hashing, the qualification chain, the confidence intervals, the retention windows, and the tables needed to re-derive every count unaided. Built against MRC OOH Phase 2.
