ATG's scalable marketplace technology for curated auctions seamlessly connects bidders from around the world to trusted auctioneers across three major sectors:

Industrial machinery, construction & farm equipment 

Art, antiques & collectables

Consumer surplus & retail returns

Each of our six marketplaces is the market leader in its respective sector and geography. By bringing together over 2,000 auction houses from across the world with bidders in 150 countries we generate a strong network effect and “virtuous circle”: auctioneers gain access to an increased bidder pool and higher visibility for their auctions while bidders are attracted by the incredible range and number of items available.
