How Cavline works
One screen. Two sides. Money moves in a loop.
A business lists the screen on its wall, an advertiser books it, and 70% of what they pay flows straight back to the business.

For advertisers
Reach people where they actually are
Pick your screens
A live map of real venues — every pin is a screen with its photo and its price right on it. Pick the ones your customers walk past every day; your ad plays inside the business, not lost in a social feed.
Know the price before you pay
Set how long your campaign runs with a dial and watch the price and estimated views update as you turn it. Every screen is priced on what it's actually worth — its size, placement, foot traffic, and neighborhood.
No contracts, no agencies, no surprises.
Watch it work, live
Every walk-in, QR scan, and lead shows up in real time. See the audience around your screens — age, gender, income — and change or pause your campaign whenever you want.
Cavline vs. the billboard
Our mission: raise the quality of an out-of-home impression — and let you track it.
A roadside billboard is seen for a few seconds by someone driving past. A Cavline screen is watched for minutes by someone who already walked in. Here's the difference, line by line.
- Time with your ad2–3 seconds, glanced at 65 mph~20 minutes, the average time a customer stays in the venue
- Who's watchingA driver whose eyes belong on the roadA customer already seated, waiting, and looking at the screen
- SafetyCompetes with traffic for a driver's attentionZero drivers. Zero distraction. Indoors, at eye level
- FormatStatic vinyl, or a still slide — roadside video isn't allowedFull video, looping every minute, on screens built for it
- How it's measuredTraffic counts: everyone who drove past, looking or notSensor-counted walk-ins, dwell time, and audience demographics per screen
- Proof anyone actedNoneTrackable QR codes, with every scan tied back to the exact screen
- FlexibilityOne position, one creative, locked in for monthsMany venues, swap creative anytime, weather and holiday rules
- PriceThousands per month for one faceFrom $23 per two weeks per screen
Dwell time is the network average measured by our own sensors. Prices are live marketplace listings. Roadside video restrictions vary by state; most prohibit motion on highway-facing displays.
The only screen network that pays local businesses.
Spend your ad dollars where they stay in the neighborhood — 70¢ of every one goes straight to the café, gym, or barbershop showing your ad. Not a media conglomerate.
For hosts
The screen on your wall should be paying you
Your screen, on the market
Sign up as a host, list the screen you already have — or buy one — and advertisers can start booking it. Your foot traffic becomes a second income for your business.
Rather stay hands-off? A cohost can manage the screen and sell the ads for you, paid out of your share.
Reject anything. Earn from everything.
Every ad waits for your tap before it ever touches your screen — reject anything that doesn't fit your space, no explanation needed. Everything you let through pays you 70% of the campaign, straight into your wallet.

Everything people ask us
What is Cavline, in one sentence?
Cavline is a marketplace where local businesses rent out the screens in their space to advertisers, and earn money from the people already walking through their doors.
Who owns the screen?
The business does. A host either uses a screen they already have on the wall or buys one, then puts it on Cavline for advertisers to book. Cavline doesn't own the hardware — the host stays in control of their space.
How much do hosts earn?
Hosts keep 70% of the profits from every campaign that plays on their screen. Prefer to be hands-off? A cohost can manage the screen and sell ads for you — you share part of your 70% with them (15% if the screen is yours, 30% if the cohost supplied the screen).
What does advertising cost?
Every screen is priced individually based on its size, placement, foot traffic, neighborhood, and how often your ad plays. You see the exact price — and an estimate of the views you'll get — in the app before you pay anything.
What counts as a view?
A real person walking into the business while your ad is on the screen. We price by walk-ins — one visitor is counted as seeing your ad at least once during their visit, and since ads repeat every minute, one visit can mean your ad was seen multiple times.
Where is Cavline available?
We're live today and expanding soon across New York State and New Jersey. Download the app to see the screens near you.
Do I need the iPhone app?
Hosts run their screens from the iOS app. Advertisers can do everything right here at cavline.app — build campaigns, generate designs with AI, set weather rules, track QR scans and live walk-ins — no download needed.
How do I get started?
Download Cavline on iOS and sign up — as a host if you have a business with foot traffic, or as an advertiser if you want to reach it. Advertisers can also start on the web: log in at cavline.app and launch from the browser.
