A type of business model that facilitates interaction between customers. Customer to customer businesses provide individuals with a place to converse, exchange and interact with other people. Also sometimes referred to as "C2C".

Many C2C businesses have online operations. Online auctions and classifieds such as Ebay and Craig's List are examples of very successful customer to customer business models. These sites don't look to directly sell goods to their members, instead the customers are exchanging with other customers.
