Haggadot.com was founded in 2007, by Eileen Levinson, a graduate student in Graphic Design at California Institute of the Arts. In her graduate seminar with Louise Sandhaus and Ed Fella, Eileen was given the assignment to imagine "the future of publication" and began the concept for an online, collaborative Haggadah.
Haggadot.com was then workshopped at the ROI 120 Summit in Jerusalem in 2007 and 2008, and incubated as a fellow project at PresenTense Institute in 2008. Along the way, Haggadot.com has benefitted from consultation with many Jewish "techies" including Dan Sieradksi, who developed a proof-of-concept Open Source Haggadah in 2003, and Aharon Varady & Efraim Feinstein, developers of the Open Siddur Project, which is rapidly building a library of open source siddur content.
Most recently, Haggadot.com received support from Natan & Jewish New Media Innovation Fund to expand the development of the website, which will relaunch in January 2012 with new features.
