C2C, or consumer-to-consumer, refers to the business model where consumers trade with each other, typically facilitated by a third-party platform. This model is prominent in marketplaces where individuals buy and sell goods or services among themselves, often through online platforms. Examples of C2C platforms include eBay, Craigslist, and peer-to-peer marketplaces like Etsy. C2C transactions have grown significantly with the rise of the digital economy, allowing individuals to monetize personal assets, skills, or second-hand goods, and to shop from a wide array of unique or rare items.
C2B, or consumer-to-business, is a business model where individuals sell products or services to businesses. In this scenario, a consumer or end-user creates value that a business is willing to purchase. This can manifest in various forms, such as freelance work, crowdsourcing, or influencer marketing where individuals offer their expertise, content creation, or influence to businesses looking to leverage those assets for commercial gain. C2B models have become increasingly prevalent with the growth of the gig economy and the digital marketplace, enabling businesses to tap into a global pool of independent contractors and service providers.
