List of Pitches from Saturday's event

Folks that are interested in pitching a project on Saturday morning:

Email me at so we have a sense of how many folks want to pitch. You'll have about 1-2 minutes to make your pitch.

And, it would be super great if you could show up at City Hall at about 9:30 if you're interested in pitching a project. Thanks!

Goal of the event.


  • Hack on civic data hub project?
  • Run it kinda like startup weekend, just shorter?
  • It could even be a wiki-a-thon with two tracks: one for editing pages and one for building apps using the ruby gem / node module.
  • Link up with Random Hacks of Kindness, which happens to be holding its (twice yearly) Global Hackathon on the *same days*, e.g. hold both events in the same location or hold a unified event. There is currently no RHoK Global Hackathon event for Seattle -- we can host it, post our problem definitions there. Note if the national Hack for Change folks do not know about RHoK, we should definitely get them in contact with each other.
  • Get in touch with City of Seattle, King County Emergency Services, NetHope, etc. -- find out what they might need.
  • Look at the RHoK problem definitions (requests for tech help posted by humanitarian organizations, governments).
