Business Description

Overview Nextdoor is the essential neighborhood network connecting over 105 million Verified Neighbors 1 to the people, places, and information that matter most in their local communities. Operating in over 350,000 neighborhoods across 11 countries, Nextdoor fosters trusted, real-world utility through locally relevant content and services, including news, real-time safety alerts, neighbor recommendations, for sale and free listings, and events. This focus on practical local value drives genuine, high-intent local engagement and supports a diverse ecosystem of neighbors and partners seeking to connect with neighbors. Our platform is powered by unique geospatial technology and a proprietary advertising system that enables businesses of all sizes to reach highly engaged audiences with a local focus. Through these capabilities, Nextdoor helps strengthen local communities while providing partners — including small businesses, national brands, publishers, and civic and government agencies — with effective tools to communicate and engage locally at scale. As of December 31, 2025, Nextdoor had 21.0 million Platform Weekly Active Users (“Platform WAU”) and reached 1 in 3 households in the United States. Our Platform and Our Users In 2025, we launched the new Nextdoor initiative, the first phase of a multi‑phase product transformation designed to create more engaging experiences for neighbors and partners and deliver enhanced value for advertisers. This evolution expands the platform beyond primarily neighbor-generated content to a dynamic feed enriched with timely, locally relevant information — including news and alerts — with artificial intelligence (“AI”) and machine learning (“ML”) used to help surface and personalize content for neighbors. The Nextdoor Ecosystem Nextdoor is built on the unique combination of neighbor identity, trust and proximity. Our platform is powered by our core constituencies: neighbors, businesses, and public agencies seeking to build stronger, more connected communities. Neighbors use Nextdoor to connect with their neighbors, follow local news, participate in conversations, discover and support local businesses, and exchange goods and services. Businesses use our platform to reach high-intent audiences through free Business Pages and targeted advertising, while public agencies — including fire departments, law enforcement, and municipal offices — share real-time updates, critical alerts, and community information. This ecosystem is further enhanced by more than 4,000 local news publishers whose content accounted, as of December 31, 2025, for approximately 7% of total feed volume, as well as alert partners such as Waze, Weather.com, and the U.S. Geological Survey. These partnerships deliver real-time traffic, weather, and safety notifications, increasing the relevance and utility of our platform. Key Features and Technology The user experience anchors on the Feed, a dynamic, personalized stream of neighbor posts, discussions, news, alerts, and community updates tailored by location. Our Search functionality connects neighbors to local businesses and resources, enabling discovery and recommendations that help drive visibility and loyalty for local businesses. Additionally, For Sale & Free facilitates a local marketplace where neighbors can buy, sell, or donate items within their communities. Our platform is built on a rich local data set that includes event details, recommendations, and insights into neighbor and neighborhood interests and behaviors. This proprietary data powers our unique local knowledge and neighbor graph, enabling more relevant content experiences for neighbors and more effective advertising solutions for businesses. Through ongoing enhancements in AI and ML capabilities, we continue to improve content personalization, notification relevance, and ad performance. By seamlessly connecting neighbors, businesses, and public agencies, we continue to evolve Nextdoor into the most useful, real-time resource for neighborhoods—with a clear ambition: if it’s happening in your neighborhood, it’s on Nextdoor. 1 Verified Neighbors are individuals who have joined Nextdoor and completed the verification process for their account. 6 Table of Contents Our Advertising Solutions Nextdoor offers a comprehensive suite of advertising solutions designed to deliver measurable results for businesses of all sizes.…
