Wikipedia:Crowdreferencing

Crowdreferencing is the collective effort of individuals who, usually via the Internet, reference products and suppliers to help build a marketplace base, in exchange of a royalty limited in time on these products. An early precursor of the crowdreferencing business model is Vialgo.co (2013), an online booking platform for tourism activities that created the concept to build its activity and supplier base. In the case of Vialgo.co, the crowdreferencer earns 6% of the price of the four first activities sold by supplier crowdreferenced.
