The core activity of the company biddr is to provide an online auction platform that serves as an interface between auction houses and bidders. The platform offers three main services: 1. Auction marketing: The publication of auctions on the platform to make them accessible to a global audience. 2. Live online auctions: The conduct of auctions in real-time, allowing interested parties worldwide to participate. 3. Acceptance of written bids (so-called pre-bids) prior to an auction. The company enables auction houses to conduct their auctions online and offers bidders the opportunity to participate in auctions without being physically present.
