Make money when you’re outbid

In a typical auction there is only one winner and everyone else loses. Many auctions don’t attract enough bidders and some get none at all. GBM™ turns any auction into a great experience where you either win or you make money.

You place a bid, and if someone outbids you, you get your bid back, plus a share from the pot called an incentive.
