당근 (Danggeun) operates a location-based community platform that connects neighbours in South Korea. What began as a second-hand marketplace has expanded into a broader local-life service: the 당근 app now covers used cars, listings for local businesses, neighbourhood discussions, hobby groups, apartments and cafés, part-time jobs and property, and moving, cleaning and repair services. Alongside the consumer app, the company runs 당근비즈니스, a set of tools for local businesses, and 당근페이, a payments service that extends neighbourhood connections into transactions.
Engineering work spans several domains. Location-based services (LBS) underpin the product's neighbourhood focus; machine learning and large language models (LLMs) are applied to personalisation and recommendation; advertising optimisation relies on scalable feed systems, data pipelines and data analysis to serve relevant content and offers.
The company describes a way of working in which teams define user problems first, form hypotheses and then validate them through rapid experiments and data analysis. The same approach is applied directly to product development. Employees are encouraged to take part in local meet-ups and to experience the frictions of neighbourhood life at first hand, in order to understand user needs. The stated orientation is towards community and warm connections between neighbours.
당근's operations are concentrated in South Korea.
