Nextdoor

Nextdoor is a private social networking service and mobile app that connects residents within a local area. Launched in 2011 in the United States, it operates as a neighborhood-specific platform where members join by confirming their street address, creating a sense of locality and accountability. Content is intended for people who live nearby, and users can adjust their visibility through privacy settings.

Core features include a neighborhood feed for posts, requests for recommendations, discussions about safety or neighborhood issues, and classified listings such as items for sale or services offered. The platform also supports organizing events and sharing emergency alerts or lost-and-found notices. Some cities and local organizations use Nextdoor to disseminate official information to residents.

From a business perspective, Nextdoor monetizes primarily through advertising and sponsored content aimed at local audiences, as well as services for businesses to connect with nearby customers. The company has expanded internationally, operating in the United States and several other countries, with neighborhoods spanning urban and suburban areas.

In reception, Nextdoor is described as a tool to strengthen local ties and foster neighborly exchange, though it has faced scrutiny over privacy concerns and content moderation. The platform emphasizes real-world proximity and accountability, seeking to balance open conversation with safety guidelines.
