About Fatdoor

What we're about

Fatdoor is a software platform that harnesses the spirit of community and the power of technology to help neighbors connect locally. Users can safely communicate, share resources, and make use of innovative robotics. It's a neighborhood social network, town square, and bustling village bazaar all in one integrated place.

Fatdoor.com was originally a venture backed company in 2007 that was funded by a CEO of PayPal, and professors in the Stanford University Computer Science department including Dr. Hector Garcia-Molina (Oracle board member) and Dr. Rajiv Motwani, one of the first investors in Google and faculty advisor to Sergey Brin and Larry Page.     The assets of the original Fatdoor sold to Google in 2011.   The current Fatdoor is a self-funded restart with the same name with the original CEO. 

Use Fatdoor to communicate, collaborate, and connect...

  • Rent a room, house, or car to your neighbors.
  • Invite everyone to the awesome block party coming up.
  • Let neighbors know that you found an adorable cat with no nametag in your backyard.
  • Notify nearby folks of a car accident down the street.
  • Have food and other stuff delivered to your door by the Fatdoor Bot Appetit™ (an autonomous delivery vehicle being tested in Palo Alto, national roll-out next year).
  • Record and share the neighborhood baseball game from the air with multiple angles—how cool is that? (Using the Skyteboard™, a web-connected quadcopter, in preorder now).

Redefining Your Neighborhood

Our mission is to use the latest technology to build something refreshingly old-fashioned: strong neighborhoods connected by a shared sense of community and identity.

Whether you're a gadget geek or a tech novice—a user of a gazillion apps or someone who fondly recalls when Kindle was a verb and not a device—you'll find it easy to use Fatdoor's intuitive website and mobile apps to keep track of everything going on in your neighborhood.

How Fatdoor is a Good Neighbor

We believe neighborliness begins at home. That's why we created a blend of services and features that respects your privacy and security while still offering plenty of convenience and fun.

Your Privacy

At Fatdoor, you have complete control over your information. You choose your level of privacy for each post—share with the community or just with verified neighbors. And your home address? That's your business. We never display your address publicly. Instead, we show relative distance away from the places and things you care about.

  • You decide the where, how, and who when it comes to sharing your personal information.
  • We never share your home address with other users or with third-party advertisers. (We hate spam too!)

Your Safety

Whether you're sharing news on the community board, or with a select group of neighbors, you can rest easy knowing that Fatdoor values your security.

  • All neighbors go through address verification.
  • All neighbors use their real names online. (No hiding behind vague handles. Yeah, we're talking to you, sketchyguy85.)
  • Your website is secure with password protection and industry-standard encryption.

How You Can Be a Good Neighbor

The first step to being a good neighbor is to actually meet the people living near you. At Fatdoor our goal is to bridge the gap between the online world and the real world to help neighbors get to know each other in a safe environment. We believe genuine connections create robust communities.

Sure, lending a cup of sugar is nice, but neighborliness goes beyond that. We all learned the Golden Rule way back in kindergarten, but sometimes we need a reminder: treat others the way you want to be treated. Simple, right?

Be Respectful

  • Discuss and debate but don't attack.
  • Contribute to discussions without hijacking the conversation.
  • Communicate privately when the message is only relevant to a small few.
  • Don't use offensive language or post inappropriate content. In other words, don't say anything that would embarrass your mom.

Be Helpful

  • Participate in community discussions.
  • Answer questions and offer friendly advice.
  • Let neighbors know when you have a room, house, car, etc. for rent. They may have family and friends in town.
  • Share your favorite restaurants or other cool local businesses that you like.
  • Pass along important news or fun events.
  • Team up on neighborhood projects.

Be Yourself

  • Use your real, full name. People like to talk to other people, not their user handles.
  • Have a complete profile, including photo. This inspires trust.
  • Sign up just as you. We think it's great if you're part of a couple, family, or business, but our goal is to connect individuals.
