C2C, or Consumer-to-Consumer, is a business model where consumers trade with each other using a third-party platform or marketplace. In this model, one individual sells a product or service to another individual. Popular examples of C2C platforms include eBay, where individuals can sell goods to each other, and Craigslist, where people can sell goods, offer services, or even rent properties. Other examples include classified advertising websites and online marketplaces like Etsy, where crafters and artists sell their goods directly to consumers. The platform provider typically makes money through fees or commissions on these transactions. The C2C model allows consumers to benefit from the profits of their transactions rather than having to rely on a business to act as a middleman.
