Nextdoor

The dominant hyperlocal neighborhood social network with verified residential audiences, uniquely positioned between social media and local search advertising

Nextdoor is a neighborhood-focused social networking platform used by over 90 million verified neighbors across more than 300,000 neighborhoods in 11+ countries. The platform enables residents to share local recommendations, safety alerts, community events, and buy/sell listings, while giving businesses and advertisers the ability to reach highly targeted local audiences based on precise geographic proximity — down to the neighborhood level. In the AdTech ecosystem, Nextdoor offers a unique hyperlocal advertising proposition that neither traditional social platforms nor programmatic networks can replicate. Its advertising products include Neighborhood Sponsorships, Local Deals, and display advertising formats that allow national brands, regional businesses, and local SMBs to engage with verified, location-authenticated users. The platform's first-party data is particularly valuable because users must verify their home address to join, creating a high-trust, high-intent local audience. Nextdoor went public via a SPAC merger in November 2021 (NYSE: KIND) and has been focused on monetization growth and international expansion. The company competes with Facebook/Meta's local features, Google's local advertising products, and platforms like Patch and Alignable, but maintains a differentiated position as the only scaled, dedicated neighborhood social network with verified residential data at its core.
