Verification infrastructure for digital out-of-home, modular by design.

  • Platform overviewHow the parts fit together: wrap the creative, read the glass, grade the play.
  • PassportFor everyone. Wrap creative once, verification rides inside. Harvester-compatible by default on fitted screens.
  • HarvesterPatentedOn-glass sensor that produces Proof of Display, independent of the player log.
  • vTrust ScoreOne comparable score from all the proof on a play. Glass proof counts only where a Harvester is fitted, never invented.
  • IntegrationsAPI, webhooks and MCP, pipe verified plays into the exchanges and tools you already use.

Questions

Questions platforms ask

Who decides whether a play clears?
You do. Vojo scores every play and sends the score back; the bar is your campaign rule, your exchange floor or your buyer's SLA. A 70 clears a HIGH bar and misses a MAX one, and that call is made in your pipe, not ours.
What happens on screens without a Harvester?
Plays still score from the evidence that is there, but never into MAX (75 and up). Only a Harvester match on the glass can reach that band. If no Harvester is fitted, glass credit is not invented.
Which exchanges are you integrated with?
We are working with exchanges to bring verification into the pipe by default. Partnerships will be listed on this site as they go public. If you run a platform and want to talk, email [email protected].
