There are a few distinct categories of online marketplaces: peer-to-peer (P2P), business-to-customer (B2C), and business-to-business (B2B). Whomever sells and whoever buys on the platform are referred to by these terms. P2P marketplaces are online platforms similar to Airbnb in which the majority of users (both customers and job providers) are private individuals. Businesses are able to connect with and sell to individuals through the use of B2C marketplaces such as tennerr Marketplace. B2B markets link firms on a more specific level, such as GREXI and LoopNet, which are both commercial property platforms.
