We enable auctioneers to compete effectively online by providing them with the tools and technology to access a global online bidder base in a cost-efficient way.

ATG powers critical components of the auction value chain

Through the combined offering of technology, digital marketing capabilities and a global bidder base, auctioneers operating largely in the mid-market are able to operate more efficiently and grow their business.

We offer multiple auction selling formats from times online-only auctions, to live online-only auctions, to hybrid auctions.

Bidders from over 170 countries use our seven marketplaces to discover, bid on and pay for a wide range of unique curated secondary market items.

Our marketplaces each have a first mover advantage


ATG differentiates itself through scale, technology and a shared success model

Our large auctioneer base with very high retention rates demonstrates the value that our multiple marketplaces and network effect offer to our auctioneers.  Attracted by a scaled collection of unique curated secondary goods, we also have the largest online bidder base for curated auctions, with over 172m bidding sessions in FY22 which helps drive a virtuous cycle.

Our technology enables incremental volume at minimal additional cost. We are committed to continually improving the online bidding experience. Owning multiple marketplaces allows us to apply best practices across the platform, whilst also offering more opportunities for our auctioneers.

For over 50 years we have worked with partnership with auctioneers.  Our shared success model aligns ATG's ambitions with those of our auctioneer partners such that together we are united in growing the auction industry.
