Nextdoor

Nextdoor runs a two-sided platform. On one side, it attracts residents with free neighbourhood networking, local recommendations, alerts and classifieds. On the other, it sells access to that verified local audience to paying advertisers through self-serve and campaign-based ad products. Free business pages and free public agency tools help seed supply, engagement and local presence, which can then be converted into paid advertising demand.

Nextdoor Holdings, Inc. operates a hyperlocal social platform where verified residents interact with neighbours, exchange recommendations, discuss local issues, receive alerts and use local marketplace-style features. The product is delivered through web and mobile surfaces, and its core consumer value proposition is a trusted neighbourhood network built around address verification rather than broad social identity.

The company makes money primarily by monetising its owned audience through advertising. Its commercial products include a self-serve ads platform for small businesses, enterprise brands, agencies and public sector organisations, plus free business pages that function as an organic entry point into paid promotion. In practice, Nextdoor is both a consumer social platform and a walled-garden advertising platform focused on neighbourhood-level targeting and local intent.
