What is Hack to End Homelessness?
Hack to End Homelessness brings together Seattle's housing advocacy community and service providers with the best minds in technology and innovation. Our goal is to design and build solutions to all forms of homelessness, from the homelessness we see on the streets to the hidden problem of family homelessness.
Why Hack to End Homelessness?
We believe that the technology industry can and should be a leading force for good in our city. Every member of our community is impacted by the twin issues of homelessness and affordable housing. As Seattle grows, we want to make sure it remains a dynamic, safe, and affordable place for all of us to live.
What projects will be worked on at the hackathon?
Potential projects range from data visualization and infographics, to creating new social networks and crowdfunding platforms, to helping with critical internal IT needs. The projects proposals all come directly from experts at local service providers and advocacy organizations, which ensures that what you work on over the weekend is fulfilling an urgent need of the community. And those experts will be present throughout the course of the weekend working one-one-one with your team.
