The document discusses spare capacity, or unused and underutilized business resources like empty hotel rooms or plane seats. It introduces BBX, which allows businesses to "bank" their spare capacity by listing it on BBX's online marketplace and directories. BBX then helps sell this excess inventory and capacity. In exchange, businesses earn BBX pounds that can be used for business or personal expenses or to gain marketing and networking benefits. BBX also offers an ambassador program where members can refer other businesses and earn a percentage of their BBX sales.
