Consumer-to-Business (C2B)
Consumer-to-Business (C2B) is a business model where consumer input dictates the terms of the deal they receive from a business. This can come in the form of consumers giving feedback on a product or bidding for their desired price.
Example:
Everlane, an online clothing company, supplements its traditional B2C model with a C2B opportunity for its customers to name the price that they pay on certain items. In addition, Instagram influencers provide C2B services by leveraging their popularity and great photographs for the benefit of large corporate sponsors.
