How APG SGA and Alma Quattro continue to connect brands with millions every day
As we move well into the first quarter of the 21st century, some companies continue to withstand the test of time—through decades, wars, and global crises. Our parent company, the Swiss-based APG SGA, is marking 125 years of successful operations this year and celebrating the story of the billboard as a timeless and trusted medium.
Founded back in 1900 in Geneva, the company was listed on the stock exchange as early as 1904 and has remained the market leader in Switzerland ever since. With over 500 employees, it operates in 17 cities, maintaining a network of both traditional and modern outdoor advertising media.

At the same time, while Serbia is out on the streets, the Serbian company Alma Quattro, which is 100% owned by APG SGA, is now in the year in which it marks 31 years of existence and operations—and can proudly state that it has been, and remains the market leader in Serbia. Since its founding in 1994, Alma Quattro has made an exceptional contribution to the development of a new communication channel and, as a pioneer, has consistently stayed one step ahead of the rest. Together, APG SGA and Alma Quattro operate across more than 150,000 surfaces, providing media support to both international and domestic clients and brands in achieving their advertising goals.
From the very beginning to the present day, Alma Quattro has facilitated thousands of business arrangements, established hundreds of millions of contacts, and, through our advertising media network, launched numerous businesses, products, and services. Today, when this matters more than ever, our company embodies everything that defines the global out-of-home industry.
Public transport shelters at over 800 locations represent a public asset that serves the people of Belgrade while also delivering advertisers’ messages across more than 1,700 advertising surfaces.

The shelter network is produced, installed, and maintained by Alma Quattro at its own expense as part of a Public-Private Partnership with the City of Belgrade. In doing so, the city secures long-term budget savings, thanks to Alma Quattro’s full financial and logistical support in maintaining this vital component of the public transport infrastructure.

As with all global providers in the OOH industry, the portfolio of APG SGA and Alma Quattro includes classic billboards, illuminated billboards, LED and LCD screens, city light displays, as well as large formats such as bigboards. All of these advertising media are available to advertisers and are positioned along key traffic routes across the city, including pedestrian zones, forming an extensive and well-distributed network.
With over 70,000 square metres of advertising space covered by Alma Quattro in Serbia, this represents a vast media resource and a powerful platform tailored to both small and large advertisers.
