What is airbnb? airbnb is an innovative company which is practically inventing the sharing economy. airbnb is the first innovation in the lodging industry since hotels grabbed all of the market share. The formula is elegantly simple: Property owner has space. Traveler needs a space. Both use airbnb to connect. airbnb does all of the global advertising, allowing a far greater reach than the property owner could ever have on his or her own. The resource already exists, but now it’s made profitable for everyone involved.
