Blockboard


Blockboard (originally BlockChalk) was a mobile application that helped people form closer bonds with their neighbors. I co-founded Blockboard in 2010 with Dave Baggeroer and Josh Whiting, with seed funding from a group of respected investors including Battery Ventures, Kapor Capital, Founder Collective, Harrison Metal, Naval Ravikant, and Joshua Schachter.

As an iPhone app, Blockboard used GPS to determine in which neighborhood you were located and then gave you access to a shared virtual bulletin board on which neighbors could share information about everything from crime and safety to things for sale. By integrating with 311 services the app also enabled users to directly report problems (such as graffiti, potholes, and broken streetlights) to their city.

Blockboard was acquired by Klout in 2012 and is no longer available. Happily, services like Nextdoor have arisen which address many of the same problems we were trying to solve with Blockboard.
