Upload or send via API: video, image, or HTML in, one deployable Passport creative out. Delivery, identity, and smarts ride in the wrap.

The platform
Nothing is invented.
Vojo Passport™ puts the creative on rails. Vojo Harvester™ reads the glass where it is fitted. vTrust Score™ grades the play from the evidence actually present.
When a layer is missing, the score says so instead of filling the gap. That is the whole design, and it is why the number survives an argument.

Why we exist
DOOH still pays for delivery. Buyers deserve plays that earned it.
A lit panel is only the start. Quality, duration, and the rest of the play decide if it counts.
What follows is the gap, the rails, and the score that settles the buy.
Vojo is pledged to making DOOH — and advertising as a whole — a more trusting, transparent, and sustainable industry.
Buyers
need proof when the campaign demands it
Networks
install proof where inventory needs it, so verified supply grows with the fleet
SSPs / DSPs
need a score in the pipe, not another stack
The gap
The report says played.The panel says nothing.
Creative left the server. The player wrote a log. The buy cleared. Nobody asked the glass.
So the whole market pads. Networks deliver ten percent or more above what they sold, so the count cannot come up short. Buyers take the bonus and cannot tell generosity from a correction. Exchanges clear the trade on a number none of them can stand behind. Nobody wants the cushion. It is simply what you do when nobody can prove the play.

Dark. Wrong input. Half a play. Still billed.
That’s the gap. We exist to close it.
Vojo
Verification infrastructure for DOOH.
One product under the buy. Vojo Passport™ puts creative on the rails. Vojo Harvester™ watches the glass when it’s fitted. Together they feed a vTrust Score™.

How Vojo works
Wrap it. Run it. Score what actually played.
Three beats on every play, from creative wrap to what the glass actually did.
Wrap
01Creative enters through Passport
Wrap once. Passport puts every play on the rails, with delivery, identity, and smarts included.
Run
02It runs on your inventory
Keep your players and CMS. Vojo sits underneath and follows the play.
Score
03Harvester raises the bar
Fit Harvester, patented proof of display, and the sensor confirms what hit the glass. vTrust scores the full play from the evidence present. No Harvester? That glass layer stays empty. We never invent it.
Vojo Harvester™
Patented proof of display. The gold standard for glass.
Independent of the tag, the player, and the network. Patented proof of display when glass assurance matters.
Vojo Harvester™ is patented proof of display, independent of the tag, the player, and the network. A sensor on the panel that fingerprints the creative on glass. Tags and logs can't substitute for it. vTrust scores the full play; Harvester is the glass layer when fitted.
Patented
Proof of display, granted in the UK and US. The verification standard others measure against.
Independent
Not self-reported by the player, the network, or by us. The sensor watches the panel whoever delivered the ad.
On-glass
Fingerprints what rendered, linked to the Passport wrap on that play.

Score anatomy
One number per play. Every layer that was present.
Think of it like the reCAPTCHA score, for the physical digital medium.
The proof model shows one play against delivery. vTrust is the composite: layers weighted at play level, then aggregated upward.
vTrust is not a single check. It weights glass, quality, duration, and integrity from the evidence on that play. Harvester supplies the glass layer when fitted. Without it, that layer stays empty. Scores roll up to screen, site, and fleet views.

“We already do all of this”
Who says it ran? And who actually knows?
Today both answers are the same: whoever sold the slot. That is not a reporting problem, it is a trust problem, and it is why every rate ends up being a negotiation about how much benefit of the doubt you are owed. Vojo answers both questions on every play, from outside the sale.

Wrap, layers and composite score all stream back as one event per play. Vojo is third party to every metric available, composes vTrust Score, and sends it back. Webhook or pull.
Built for SSPs and DSPs clearing programmatic inventory. We are working with exchanges to bring verification into the pipe by default. Partnerships will be listed on this site as they go public. Not listed yet? Email partners@vojo-media.com.

Same play, one payload
The play_id and layers from scoring (passport, player, and harvester when fitted) stream as one event. PLY-204 at 94 is the same play you saw above, not a separate report.

Your threshold
Vojo scores; you clear. A 94 passes one bar and fails another, depending on the campaign rule, the exchange floor, or the buyer SLA. Your call in the pipe.

Third party to the metrics
Not the network’s rollup, not the player log. Vojo reads every layer present, composes the score independently, and sends it back.

Why it matters
Trust. Transparency. Sustainability.
Vojo is pledged to making DOOH — and advertising as a whole — a more trusting, transparent, and sustainable industry.
The programmatic era needs all three, not slogans. Trust in the evidence, transparency in the score, sustainability in cutting wasted spend and wasted delivery.
Trust
Evidence you don't take on faith
Vojo is independent and third party to every metric on the play. Vojo Harvester™ is patented proof of display when fitted. We never invent glass credit.
Transparency
The same play, the same score
vTrust Score aggregates every layer present, across play, screen, site and beyond, and streams back over the API. You see what counted; you set the threshold.
Sustainability
Less wastage, in the buy and on the planet
Don't pay for black screens, wrong input, or tag-success plays that failed on the glass. Don't serve unhealthy panels, or over-play to compensate for downtime you can't prove. Vojo Harvester™ monitors the fleet remotely: site visits only where something's wrong, not to vet screens already working. Spend and energy follow what actually delivered.
Who uses it
Use when you need it. Install where you need it.
One verification infrastructure, adopted in parts. Agencies call it per buy. Networks install on the screens that need it. Exchanges hook in over the API above.
Buy side
Agencies & buyers
Independent verification when the buy needs it, campaign by campaign. Passport verifies on any network today; vTrust Score aggregates every available metric across play, screen, site and beyond. As more networks install Vojo Harvester™, patented proof of display deepens the score, and verified supply surfaces in the public directory as it grows.
Buyer overviewSupply
Networks & media owners
You sell the inventory. Install Vojo Harvester™ where glass proof matters, on the screens that need it. Vojo is independent and third party to every metric; vTrust Score aggregates upward without replacing your CMS or player. Verified supply surfaces in the public directory as proof rolls out across your fleet.
Network briefingExchange
SSPs & DSPs
Independent, third-party verification built for programmatic scale. Vojo aggregates every available metric into vTrust Score across play, screen, site and beyond, then streams it back over the API. You set the threshold before clear, settle, or make-good.

Operators & integrators
You wire it in: wrap in Passport, deploy Vojo Harvester™ on the panels that need it, pipe vTrust Score into the CMS, player, or exchange APIs you already run. For in-house ops teams and integrators serving one network or many.

Commercial model
No long contracts. Pay for proof as you use it.
Everyone else sells this as a platform deal: a multi-year commitment and a round of sales calls before you can try anything. Four things, priced for how you actually use each one.
Free
Platform & CMS
The whole portal, for your whole team. Unlimited users, sites and advertiser accounts. No trial, no tier with the useful parts removed.
Per play
Verification
Passport rides inside the creative, so there is nothing to install and nothing to fit, whether you own the screens or are buying across networks you do not. You pay for the plays you score, and you stop when you stop.
Per screen
Vojo Harvester™
The on-glass sensor, fitted only to the screens worth proving. Priced by how many you take, so start with the sites where proof changes the rate.
Included
API + attest
Exchange and CMS hooks come with the infrastructure. Pull the score into your own pipe, or have it pushed. There is no separate integration fee.
Request pricing
Start on one screen. There is nothing to sign before you find out whether it works. And we have our own Smart DOOH Player if you want it: monthly per screen, though nothing in the verification needs it. See the player
