The problem
Stop blind offline spend.
Billboards. Radio. Local TV. Direct mail. You pay for them every month. None of them tell you what they earn in store.
No data.
Billboards come with photos. Radio with ratings. TV with GRPs. Mail with a drop count. Nothing on who came into your stores.
Data you can't trust.
Platforms report store visits from phone GPS. Our study of 150,000 visits across 400 sites: about 95% of those visits are wrong. Clean dashboard. Wrong numbers.
Either way, you pay to reach people who will never come in. That spend has a name: media waste.
Kairos AI barometer
Media waste, channel by channel.
The share of spend that reaches people who never set foot in your stores. Measured in store.
Across our studies, that share runs from 18% to over 77%. That is not a measurement gap. That is cash lost on every campaign.

How it works
Measured by in-store sensors.
Our own sensors, in your stores. No GPS. No third-party location data.
Sensors in your stores.
We ship them. Your team sticks them near the door. Free, no wiring, no IT ticket. From day one, every visit is observed, 20x more precise than GPS.
Matched to your media.
Each visit is matched to campaign exposure. Billboard by billboard, station by station, ad set by ad set.
Budget steered by store revenue.
Money moves every week to the media that contributes most to each store's revenue. Same budget.
How we measure →The sensor
The sensor behind every number.
A small device near your door. It is what lets Kairos AI steer your budget by store revenue.
Passive.
It only broadcasts a signal. It collects no personal data.
10-year battery.
No power outlet, nothing to plug in. Nobody can unplug it, so no visit data gets lost.
Free.
No hidden cost. No subscription. Replaced free if one fails.
Trains Kairos AI on your stores.
Your own store visits train our algorithms. That is what lets Kairos AI steer each dollar by its contribution to your store revenue.
Why not GPS?
5%
of GPS visits are accurate within 16 feet (5 m). In a city center, GPS can't tell your store from the one next door.
35%
of GPS visits are accurate within 330 feet (100 m). Not reliable in a mall or along a retail strip either.
20x
more precise than GPS. The visit is observed inside your store. The only way to steer every dollar toward store revenue.

FAQ
Questions, answered.
Everything you need to know about recovering the media budget you spend blind.
Get early accessDo I need to be a big chain?
No. Kairos runs in 45,000 stores with Europe's largest chains. The US offer is built for retailers with 1 to 200 stores. If you buy billboards, radio, local TV or mail and can't tell what they earn in store, part of that budget is lost today.
Do I need more budget?
No. We start from the media you already buy. Sensors are free, with no hidden cost.
Do you promise more store visits?
No. We measure visits. We don't promise them. We steer your budget by its contribution to store revenue. On promotions and sales events, we also read the incremental lift with a control group.
How is this different from GPS or foot-traffic data?
GPS visits are mostly inferred. Our study of 150,000 visits across 400 sites found about 95% of them wrong. Our sensors sit in your stores. Every visit is observed.
Can I keep my agency?
Yes. Your agency keeps buying. You get an independent read on what each budget earns in store.
