Auction Technology Group, an operator of marketplaces and auction services for curated online auctions, completed the acquisition of Vintage Software, a platform that facilitates estate sales across the US for $40m. "As a leading US estate sale listing site, estatesales.net is a natural fit for ATG as we unlock further areas of value within the secondary goods market and facilitate another part of the circular economy. We are excited by the multiple growth opportunities ahead, including enabling more sellers of unique and specialised secondary items to cross-list across multiple marketplaces and gain access to a larger pool of bidders and buyers, as well as the opportunity to develop ESN into the leading online estate sales platform in the US. We look forward to welcoming Micky and the estatesales.net team into ATG," John-Paul Savant, Auction Technology Group Chief Executive Officer.
