Guidestar Report


Sahana” means “relief” in Sinhalese, a language of Sri Lanka, where the first "Sahana" product.  It was developed in the immediate aftermath of the 2004 Indian Ocean earthquake and tsunami by the Lanka Software Foundation (LSF).  In early 2009, at the request of the LSF, the software project spun off to become it's own US-based non-profit organization with a mission to develop open source software for humanitarian purposes.  Since then, the SSF has developed a number of open source software products and implemented solutions used by some of the world's largest relief organizations, as well as a myriad of emergency services agencies in uniquely vulnerable nations such as the Philippines, Nepal and Bangladesh.

Devin Balkind (President, Director): Devin works at the intersection of the nonprofit sector, the Free/Libre/Open-source (FLO) movement, and grassroots community organizing initiatives to help each benefit from the best practices of the others. He began his career as an entrepreneur who developed a challenge-based crowdfunding platform for nonprofit organizations. During this experience, he realized that a lack of collaboration among nonprofits was limiting the social sector’s effectiveness much more than its lack of funding. Since then, Devin has been applying FLO methodologies to civic challenges by developing and deploying software tools and operational techniques for a wide range of groups including software development communities, grassroots organizing initiatives, new media publications, conventional nonprofits, small farms, community spaces and, most recently, disaster relief coalitions. Devin holds a Bachelor of Science from Northwestern University.
