Nextdoor (NYSE: KIND) is a verified-by-address neighborhood social network founded in 2008 and headquartered in San Francisco.
Consumer social media / local advertising, not a vertical B2B SaaS. Neighbors post recommendations, lost pets, safety alerts, crime reports, and marketplace listings to their verified neighborhood and adjacent ones.
High within the consumer neighborhood-network category in English-speaking markets, modest as a B2B platform.
The data inside Nextdoor is primarily community-generated consumer content (posts, replies, recommendations, marketplace listings, event RSVPs, safety alerts) plus advertiser performance data (impressions, clicks, conversions, audience segments) and business-page metadata (claims, recommendations, reviews, deals).
Mature (founded 2008, public since 2021 via Khosla SPAC).
API access requires partner approval and is scoped to advertising/content-sharing use cases, no general-purpose data API for businesses to extract their own followers, posts, or recommendations. Conversion API (CAPI) requires non-trivial server-side instrumentation; SMBs typically need a CDP (Adobe, MetaRouter, Segment) or developer help to implement. Full sourced list under Sources below.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
