We’re building a network that will reach everywhere.
And imagining what it becomes.
Every device we’re building shares a useful set of properties: a permanent and redundant connection home, an identity fused into silicon — and lots of idle time.
This page is about how we put that idle time to work.
A device has more spare
than processing power.
When we started thinking about idle capacity, we assumed the answer was compute. It isn’t — compute turns out to be the least interesting thing a Justworx device has going spare.
A device on the Justworx Air Network is also a fixed point in physical space. It has a permanent identity that cannot be forged or copied. It sits on the customer’s electrical system. It is listening to the radio spectrum around it. And it will do all of this for years at a time, in places conventional infrastructure never reached.
None of that is compute. All of it is scarce.
One device that senses something is a feature. Millions of them, in known places, with identities that can’t be faked, become an instrument — one no data centre can build, because each device is installed to do a real job and pays for itself doing it. The spare capacity comes free.
Five programmes follow from that. Each monetises a different thing a Justworx device has spare.
Five things a Justworx device has spare.
Grid
The spare cycles — and the spare places they’re in.The AI industry’s fastest-growing cost isn’t the model, it’s the pipeline feeding it. Collection, cleaning, deduplication and vectorisation — work that splits into millions of independent pieces, none of which needs to happen in a data centre.
Explore Grid →Sentinel
The spare position on every electrical system we reach.Electrical arcing faults precede a significant share of building fires, and they’re detectable — but only by something watching the waveform continuously, at the point of use. Smart meters sample fast and report slowly; the data dies at the meter for want of a pipe wide enough to carry it.
Explore Sentinel →Beacon
The spare radio — and the places it will reach.Every Justworx device listens for the network the moment it powers on. Having it also notice a tag nearby turns the whole fleet, as it grows, into a finding network — one that will cover mine sites, farms, plant rooms and depots, because that’s where our devices are headed.
Explore Beacon →Root
The identity we burned in before anyone required it.Every Justworx device carries a unique cryptographic key fused into silicon at manufacture. We did that years ago for our own reasons. Regulators have since decided it should be mandatory — which turns an architectural choice into a head start.
Explore Root →Witness
Proof that something really happened.As generative systems make every image, document and reading trivially fakeable, the scarce commodity stops being data and becomes provenance. A reading signed by device-burned silicon proves it came from that specific hardware, in that place, at that time.
Explore Witness →We know exactly how this goes wrong.
The idea that millions of small owner-operated devices could become valuable infrastructure is not new. The most famous attempt is worth studying closely — not because the technology failed, but because the economics did.
The problem wasn’t expensive hardware. It was that the money came from the wrong side of the transaction. Between mid-2021 and mid-2022, the largest network of its kind earned roughly $92,000 from data actually crossing it — against $53.3 million from selling hardware to the people hosting it. Its founder’s own figures put data transfer at about $6,500 a month against $2M in total revenue.
Almost none of the money came from customers using the network. Nearly all of it came from new participants buying in. That structure has exactly one outcome: early hosts earned extraordinary returns because few devices shared a fixed pool, later hosts earned nothing because the arithmetic guaranteed it, and when growth stopped so did everything else.
Three rules we’ve written into the design
- We will never sell a device on the promise of what it might earn. Justworx hardware is bought because it switches, senses or tracks something. Anything these programmes contribute is a by-product of a device that pays for itself doing its actual job.
- We will never publish a yield. No projected returns, no earnings calculators, no “typical device earns.” If compensation exists it’s a share of revenue we’ve actually been paid — never a forecast, never an issuance, never an investment.
- We won’t build capacity and hope. Supply is the easy half, and it’s the half that bankrupts you. No workload goes live until someone is paying for the output.
None of this is restraint on our part — it’s structural. There is no token, no yield and no return to promise, so there’s none to break. Our devices are built to do a job, and they’ll do it whether any of this exists or not. That isn’t a smaller version of the original idea. It’s the only version that was ever going to work.
Air will make connectivity free.
This is what we’re building on it.
Every programme on this page is in development. None of it ships today, and we’d rather tell you that plainly than let a roadmap read like a product catalogue.
What exists today is the hard part we’ve spent six years on: the design for a private wireless network that builds itself, hardware identity fused into every unit, and a model where the fleet grows with every product a partner ships. Everything above is what that foundation will make possible.
Forward-looking. Programme names (Grid, Sentinel, Beacon, Root, Witness) are working titles for capabilities in development — not products available today. This page describes what the foundation we’re building makes possible, not a shipping roadmap.
