Marketplace business model is often referred to as C2C or consumer to consumer, B2C or business to consumer, B2B or business to business, or D2C or direct to consumer. eBay was mostly C2C, but then many businesses started selling on eBay as well, so it’s now B2C as well as C2C. Craigslist and Etsy are really the only mainly C2C marketplaces left, while businesses have all jumped into the marketplaces now. The model allows sellers to upload and sell their own products to consumers through the marketplace platform. This allows them to get their products in front of many potential consumers, and usually means giving up a percent of each transaction for the privilege of both exposure and using the marketplace platform.
