About Us

Nextdoor is the world’s largest social network for the neighborhood. Nextdoor enables truly local conversations that empower neighbors to build stronger and safer communities.

Building connections in the real world is a universal human need. That truth, and the reality that neighborhoods are one of the most important and useful communities in our lives, have been a guiding principle for Nextdoor since it was founded in 2011. Neighbors in the United States, United Kingdom, France, Germany, the Netherlands, Italy, Spain, and Australia are using Nextdoor to:

  • Find a trustworthy babysitter or recommended house painter
  • Spread the word about a lost dog
  • Organize a neighborhood watch group or quickly get the word out about a break-in
  • Share information during a natural disaster
  • Receive information from local public agencies
  • Find a new home for an outgrown bicycle

Nextdoor is a privately-held company based in San Francisco with the backing of prominent investors including, Benchmark Capital, Greylock Partners, Kleiner Perkins, Axel Springer, and others.

Nextdoor is free, and it’s easy to sign up.

Our Manifesto

We are for neighbors.
For neighborhood barbecues. For multi-family garage sales. For trick-or-treating.
We’re for slowing down, children at play.
We’re for sharing a common hedge and an awesome babysitter.
We’re for neighborhood watch. Emergency response. And for just keeping an eye out for a lost cat.
We believe waving hello to the new neighbor says, “Welcome” better than any doormat.
We believe technology is a powerful tool for making neighborhoods stronger, safer places to call home.
We’re all about online chats that lead to more clothesline chats.
We believe fences are sometimes necessary, but online privacy is always necessary.
We believe strong neighborhoods not only improve our property value, they improve each one of our lives.
We believe that amazing things can happen by just talking with the people next door.

We are Nextdoor. We are simply you and your neighbors, together.
