Creating a virtuous circle that benefits both auctioneers and bidders

ATG is an aggregator in the large and fragmented auction industry. We simplify and integrate multiple parts of the online auction process, from the cataloguing of items to marketing, auction hosting, bidding and most recently payment solutions.  In doing so, we enable auctioneers to become genuine online businesses in a cost-efficient way.
