About the Company

GBM

Online auction platform with bidder incentives

GBM operates gbm.auction, an online auction platform that pays bidders a payout whenever another bidder places a higher bid using its Bidder Incentive Auction™. The system uses proprietary auction technology to create ongoing bidding incentives, so bidders can earn cash rewards even if they don’t win, while auctioneers can push higher final prices. It differentiates itself from typical online auctions by replacing the zero-sum dynamic with continued participation incentives and is connected to Bidwrangler, a related platform. The goal is to increase bidding activity and hammer prices, improve bidder engagement, and grow the collectibles market.
