Overview
Danggeun Market, known internationally as Karrot, is a Seoul company founded in 2015 that runs a hyperlocal second hand marketplace. Listings are restricted to a user's own neighbourhood so goods are handed over in person, which built unusually high trust and daily usage. The company has expanded into local advertising, jobs and payment services.
