Nutron Wall Network · Phoenix metro · Being built now
Walls where people wait. A framed poster or a smart screen. Paid to the owner. Counted for the advertiser.
Nutron leases wall space in the waiting areas of local businesses. Each wall gets a framed poster (static) for one local advertiser, or a smart screen (digital) playing short moving ads.
Each frame and screen ad can carry its own code to scan and keyword to text, so responses can be counted wall by wall. Screens also count the people in front of them, with a small camera sensor that saves no video or images and identifies no one.
Own a shop with a waiting area?
Get paid for a wall
For each frame or screen, you choose how you're paid: a flat monthly fee, or a share of the net ad revenue it earns. The numbers for your wall come in writing, before you sign. A screen also gives you part of its time for your own specials, prices and Wi-Fi password. Either way, we put it up at no cost to you and keep it up. A screen runs on your electricity.
Want customers from one part of town?
Advertise on the walls
Your poster in 10 waiting rooms in one ZIP code. Each of those shops carries one poster: yours. Or your moving ad on smart screens, near your business or across a part of town. Ads start at $5 for a basic ad on rotation. Designing the ad, peak hours, text codes and real-time reporting can add to the price, and your quote lists each one. Every format is priced in a written quote.

Money flows to the wall. Proof flows back.
Advertisers pay a flat monthly fee for frames, and for screens a monthly price that can be tiered by how many people actually look at them. Every format is priced in a written quote. Owners choose a flat fee or a share of what their frame or screen earns, with the numbers in writing before they sign. Nobody is paid per response or takes a share of an advertiser's sales.
- Solid line: money
- Dashed line: the count

Nutron: everything in between
- Signs and pays each business
- Finds and signs the advertisers
- Designs posters and moving ads
- Installs and keeps up every frame and screen
- Schedules what plays on every screen
- Counts and reports, location by location
Two counts and what they miss.
Responses, on frames and screens. A scan or a text counts to the wall it came from, so every location can be compared side by side.
The response count is the floor, not the ceiling. It can't see people who call the number on the ad or look the business up later, and we won't estimate them.
People, on screens only. A small camera sensor on the screen counts the people in front of it while each ad plays, and how many of them look at it. It has to see people to count them. The video is analyzed on the screen's own computer and each frame is erased within a fifth of a second, so it saves no video or images and identifies no one. What it sends is measurements, like counts and times.
Your quote states the number of viewers you're buying, and your agreement puts it in writing, so you know what you're paying for.
People counted is a sensor's count. It can miss people or count someone twice, and no outside auditor has checked it yet.
SAMPLE
Only measurements leave the screen, never video or images.
What it counts
- The people in front of the screen while each ad plays, and how many look at it
What it never keeps
- Video
- Images
- Who anyone is
The poster is the easy part. So is the screen.
Anyone can print a poster or hang a screen. Local advertising in small businesses breaks everywhere else.
Someone has to sign dozens of independent owners and keep every agreement straight. Someone has to keep every frame clean and every screen running. Someone has to answer the one question every advertiser asks: did anyone respond?
That usually runs on phone calls, a van and somebody's spreadsheet.
Nutron was founded in 2019 and is run by its three founders. We find what's costing a business time or money and build the system that fixes it. Usually it's work that crosses many people and places.
The Wall Network is that kind of problem, and we're building the system to run it.

The same work, pointed at your own business: the two-week operations audit
Built by Nutron, end to end.
Nutron is a Phoenix technology company: integrators, developers and solution architects who design and build software for businesses. We designed this network, and we write the software that ties it together.
- Each frame and screen can carry its own scan code and text keyword, so a response is traced to the wall that earned it.
- Each screen logs its plays, and a small sensor on it counts the people in front of it.
- One report brings it together: plays, people counted, scans and texts, by location.
The same team built a system that had to hold for 120,000 employees, and a claims flow still in production for the leading US glass-claims processor.

Straight answers about the Wall Network
What it is, who pays whom and where it stands.
What is the Nutron Wall Network?
Framed posters and smart screens for Phoenix-metro waiting areas, run by one local team. They're for auto repair and tire shops, collision centers, laundromats, barbershops, salons, cafes and vet clinics. Nutron leases the wall space from each business, sells it to local advertisers and can count the responses at each wall.
Who pays whom?
Advertisers pay Nutron. Ads start at $5 for a basic ad on rotation. Designing the ad, peak hours, text codes and real-time reporting can add to the price, and your quote lists each one. Every format is priced in a written quote.
Nutron pays the businesses that host the walls, and installs every frame and screen at no cost to them. For each frame or screen, a business chooses a flat monthly fee or a share of the net ad revenue it earns, with the numbers in writing before it signs. A screen also gives the business part of its time for its own specials, and runs on its electricity.
What kinds of businesses advertise?
Local businesses whose customers are the people in those waiting rooms. The clearest example is an accident attorney in an auto repair shop, where some of the people waiting are there after a crash.
Can a competitor advertise in the same shop?
Not in a shop with a frame. Each carries one poster, so a Poster Network's 10 shops are the advertiser's own. A competitor can run its own network in the same ZIP code, never in the same shops, whether on a frame or a screen.
Screens are shared with other advertisers. Whether a direct competitor can play on the same screen is set before you sign. Category Exclusivity keeps every competitor in your category off every frame and screen in the area you lock. It's custom priced.
Is the shop endorsing the advertiser?
No. A shop is paid a flat monthly fee or a share of the net ad revenue from its frame or screen, whichever it chose. Neither depends on how many people scan or text, and nobody at the counter is asked to recommend, sell or hand out anything.
Does a frame collect information about the people who wait near it?
No. A frame is a printed poster behind acrylic: no camera, no sensor, no screen. The only responses counted are from people who choose to scan the code or text the keyword.
Does a screen collect information about the people in front of it?
Yes, it counts them. A small camera sensor on the screen counts the people in front of it while each ad plays, and how many of them look at it. It has to see people to count them. The video is analyzed on the screen's own computer and each frame is erased within a fifth of a second, so it saves no video or images and identifies no one. What it sends is measurements, like counts and times.
Every screen carries a notice on it saying there's a camera sensor, what it counts and how to reach us. If you'd rather have no camera in your waiting room, a frame has none.
When do the first frames and screens go up?
Once founding shops and advertisers sign. We're launching in the Phoenix metro and signing them now. The first shops to sign form the first networks. Founding advertisers get first pick of shops and categories.
We won't show a network, a result or a client that doesn't exist.
Pick your side of the wall.
Owners: compare a frame and a screen, and have us call. Advertisers: check what's possible in your part of town. Either way, you'll hear from a person.
