With VojoA queried spot becomes a lookup: the play, its evidence, its score.
What your buyers get
Hand buyers the proof, not a percentage.
The report your buyers receive, built from the plays themselves.
Every play
A score on every play
Not a delivery percentage at the end of the month. Each slot that ran carries its own vTrust Score.
Every score
The evidence behind it
Which layers reported the play: Passport from inside the creative, and the glass where a Harvester is fitted.
Every site
Rolled up by screen and site
The same plays summed for the campaign, so a buyer sees the whole flight and can drill into any slot.
Start where it pays
Which of your sites need glass?
Describe one site. See whether Passport covers it on its own, or a Harvester belongs on the glass.
For this site
Passport, plus a Harvester on the glass.
- PassportRides inside the creative on every screen, with no hardware to fit.
- HarvesterWatches the screen itself. Always ships with Passport.
Why glass proof pays here
- A high rate invites the question of what actually ran. Proof from the glass is what lets you hold it.
What you’re buying
- Vojo Passport™On every screen the creative plays: which ad ran, where, and whether it finished. Nothing to install.
- Vojo Harvester™On the sites that matter: what actually reached the glass. Always ships with Passport.
- vTrust Score™One score per play that your buyers can check, rolled up by screen and site.
Questions
Questions media owners ask
- Do we have to change our player or CMS?
- No. Vojo is verification only. Your CMS and players keep scheduling and playing the inventory. Passport travels inside the creative as a standard HTML unit, and a Harvester sits on the screen itself, so nothing in your playback setup has to change.
- Do we need a Harvester on every screen?
- No. Passport covers every screen the creative plays on, with no hardware. Fit a Harvester where the argument is expensive: premium sites, audited buyers, panels you can't vouch for, and screens that are costly to visit. A Harvester always ships with Passport, never on its own.
- How is it priced?
- The verification portal is free. The rest is priced in your quote: either a monthly licence per Harvester, or pay as you go on what you verify, depending on which suits your estate.
