Nextdoor, a hyper-local social network that launched in October 2011, today rolled out a second version and announced a $21.6-million round of funding.
Nextdoor connects users within the same neighborhood. Used in more than 8,000 U.S. neighborhoods, the social network has de facto come to be used largely as a digital neighborhood watch group. Users must prove that they live within the area designated by the local administrator, and each such area must have at least three members.
The second version of the Web-only social network creates a dedicated page for safety and security content. It also allows users in one neighborhood to share some of their content with users in nearby neighborhoods.
The funding round — which will help Nextdoor expand into more markets and, likely, develop mobile apps — was led by Palo Alto’s Greylock Partners. It drew new investments from Google Ventures and Jeff Bezos’s Bezos Expeditions.
