Out-of-home is the oldest form of advertising. This is the product it never had.
Dropsignal puts an ad for every thing you sell on screens people pass every day. This is the story behind it.
The story
Outdoor advertising has always worked. A screen someone passes on the drive in, at lunch, at the gym, on the way home does something a feed cannot: it puts you in the physical world your customers already move through, next to nobody else's bid.
Online, catalog advertising is enormous. Point Google or Meta at an inventory feed and every item gets its own ad. Physical space never got that product, because creative was manual. So outdoor stayed sold the old way: one creative, one flight, a start and an end date. Nobody sold continuous coverage of a changing catalog.
Dropsignal is that product. We look at your website and make an ad for every thing you sell. If it has its own page, it gets its own ad. The ads run on screens across your trade area, each with its own response URL, a short web address on your own domain. Somebody types it in and lands right on what they saw.
How it's different
One ad per item
An agency prices per concept, so the answer is one ad. We make one for every thing on your site and keep the set current: add something to your site, it gets an ad. When it comes off, the ad comes down. Month to month, cancel anytime.
Planned from your business
We find where you do business from your site and draw a trade area ten miles around each place. You can add more anywhere you want to be seen. We pick the screens inside them, and you see the plan on a map.
Closing the loop
Every ad carries a response URL, a short web address on your own domain. When somebody types it in, they land right on what they saw, and you see every visit on your dashboard. Every play is logged by time, place and creative. Delivery is promised; response is counted.
Who's behind it
Dropsignal is built by Archway, an AI-native studio founded by Christian Aaselund. He spent over a decade as CTO at Clear Channel Outdoor, building the technology behind digital out-of-home advertising, and was an early sponsor of the medium's move to programmatic.
That experience is where the mechanics come from. Dropsignal buys the same screens the national brands run on, the same digital billboards and transit shelters, and plans every buy from the advertiser's side of the table rather than the seller's.
