The digital revolution has transformed the way we purchase almost everything—including advertising. Our business idea is a kind of "Airbnb for outdoor advertising," and here we will delve into how this model is changing the industry. Traditionally, purchasing billboard space could be a time-consuming affair: negotiations with various sign owners, long lead times, and sometimes a bit of a jungle to navigate. But what if you could book an advertising billboard as easily as booking a hotel room online? This is where the digital marketplace for outdoor spaces comes in—a platform where advertisers meet sign owners directly, with real-time visibility of the offerings.

The advantages of such a marketplace are hard to ignore. Efficiency increases dramatically. Instead of calling around or emailing back and forth with ten different suppliers, an ad buyer can log in, view all available billboards in their desired region or target group, and book with just a few clicks. A leading player in the U.S. puts it plainly: with a digital platform, advertisers can reach hundreds of media owners at once and execute outdoor purchases up to ten times faster than before. This means a campaign can be launched in just 48 hours instead of planning months in advance. In practice, we've seen examples where large digital OOH campaigns have been rolled out across countries in just a few days, thanks to programmatic technology—something that would have been science fiction just a few years ago.

The technical term for this is programmatic DOOH (Digital Out-Of-Home), which essentially means that the buying and selling of digital outdoor ads occurs automatically through software. Instead of manual negotiations, the system uses real-time bidding and data-driven management, much like online display advertising. For advertisers, this not only saves time but also ensures that the right ad appears in the right place at the right time. Through data, one can control which billboard displays car ads in the morning when commuters are passing by, and another campaign in the evening. The platform can automatically select the best spaces based on audience data—such as traffic flows, demographics in the area, etc. Machine learning can assist in optimizing the campaign on the fly: if a certain location is underperforming, the system can reallocate budget to better-performing spots. Instead of "spray and pray," we get precision-targeted outdoor advertising.

A key strength of the marketplace model is transparency and reach. Advertisers gain an overview map of available inventory – much like an Airbnb map but for billboards – allowing them to compare prices and viewing statistics. This dismantles old information monopolies, giving smaller players the same insights as large agencies. The platform also opens doors for new advertisers who may have previously believed outdoor advertising was too complicated or expensive. With simpler booking processes, clear pricing, and flexible options (e.g., shorter campaign periods on digital screens), the medium becomes more accessible. It’s akin to how Airbnb made it easy for anyone to rent accommodations globally – we make it simple to “rent” an ad space in urban environments.

For media companies and sign owners, this also brings advantages. They can reach more clients without each deal requiring personal sales efforts. An analysis indicates that the biggest benefit of programmatic OOH is precisely the efficiency of selling multiple media spaces through a single platform—reducing time spent on administration and price negotiations. Additionally, unused ad inventory can be automatically filled (because nobody likes a blank billboard). The result is higher occupancy and revenue over time for sign owners, while advertisers avoid delays with their campaigns due to "paperwork" holding things up.

A prime example of this new agility was when a well-known cosmetics company needed to launch a product quickly in the U.S. Through a programmatic OOH platform, they could plan and roll out a nationwide billboard campaign in 1,000 cities in just two days. What traditionally would have required weeks of coordination was now resolved in a snap via the system. Flexibility is also a game-changer: a campaign can be paused or altered in real-time. If the weather changes or news impacts consumers' moods, messages can be swapped out mid-campaign—something that was practically impossible with printed posters before.

Another dimension is data-driven measurement. A digital outdoor platform can provide measurable insights into exposures, engagement, and even conversions (e.g., by matching mobile data to see if people exposed to the billboard later visit a store or website). This gives outdoor advertising something it has historically lacked: clear ROI tracking. A programmatic OOH campaign generates a wealth of data that can be analyzed to optimize future advertising. It removes much of the guesswork—marketers can see what works and what doesn't in an entirely new way.

In summary, outdoor advertising is following the same path as many other industries: digitalization, automation, and platform logic. The "Airbnb model" for billboards makes it easier for buyers and sellers to connect and execute campaigns quickly and smoothly. For marketers, this means more flexibility, precision, and speed. You can book outdoor advertising at lunch and see it live that same week—and if needed, adjust the message the next day. This revolution is great news for anyone tired of cumbersome media buys and fragmented inventory data. In our digital marketplace, the physical and digital blend: we take the best of online advertising (targeting, speed, measurability) and apply it to the tried-and-true billboard. The result is outdoor advertising 2.0—just as creative and eye-catching as always, but now with turbo under the hood.
