In 2002 we were commissioned by Troostwijk Auctions (an important European auction house that specialises in large and industrial bankruptcies) to set up a web auction for the bankruptcy of KPN/Quest. This bankruptcy consisted of over 20,000 lots, with a combined purchasing value of over € 25,000,000. The auction attracted bidders from more than 60 countries. After this success, Troostwijk started using Auction-Experts software for all of its internet auctions. In the years that followed, physical auctions were gradually phased out. Nowadays, only internet auctions are organised. There are between 50 and 100 auctions a month on average, collectively featuring over 10,000 lots. Troostwijk now uses its own auction software.
