Vojo · Verification · Meridian M40
Vojo's campaign page for Meridian M40: plays booked and due, 92% verified HIGH or better, a vTrust roll-up of 82, 62% corroborated, and the four screens it ran on, each with its own score.
Swipe to see the whole page. One campaign on one scale: every screen it ran on, graded by the same rules. Sample data from a demo network.
One scaleFive questionsQuestions

One campaign, three reports

Three networks. Three formats. One scale.

Today each network grades its own delivery in its own terms. With one wrap, every play comes back the same way, wherever it ran.

One campaign, one creative, three networks

Only a play matched on the glass reaches MAX (75 and up). Where no Harvester is fitted, no glass credit is invented, and you set the score you’ll pay against.

Before you sign off delivery

Five questions. Send them to every network.

Fair to ask of anyone, including us. Copy them into your next email.

To: every network on the plan

  1. 01Who wrote this report?If it came from your own system, it's your account of your own delivery.
  2. 02Does it show what was sent, or what appeared?A schedule or playback log can't see a dark panel, a frozen frame or the wrong input.
  3. 03Which plays have evidence from outside the player?Which screens on our plan carry a sensor on the glass, and which plays did it match?
  4. 04Can we compare it with the other networks on the plan?Different formats and terms make a strong delivery look the same as a weak one.
  5. 05What would settle a disputed play?Another copy of the same log settles nothing.

What you’re buying

  • Vojo Passport™Wrap the creative once. Every play on every network reports from inside the ad, and the seller can't edit it.
  • Vojo Harvester™Where one is fitted, the same play seen from the glass. Always ships with Passport.
  • vTrust Score™Same rules on every network, so plays compare. You set the score you'll pay against.

Questions

Questions buyers ask

Do the networks have to install anything?
No. Passport travels inside the creative as a standard HTML unit and runs on any standards-based player, so operators run the creative they already know how to run. Video, image and HTML creatives can be wrapped when they can ship as a standards-based HTML unit. If you're unsure about a format, bring it to a demo and we'll say clearly what wraps today.
Is Passport independent of the network?
Yes, in the way that matters for a buyer: the report is written by the wrap, and the seller can't author or edit it. What Passport can't be is independent of the render it runs inside. That's what a Harvester adds where one is fitted: the same play, watched from outside the player entirely.
Which screens on our plan have glass proof?
A Harvester sits on a particular screen and always ships with Passport, so glass proof exists only where one is fitted. Ask which screens on your plan carry one; the score shows it on every play, because only a play matched on the glass reaches MAX.
