AllSides was founded in 2012 by John Gable, a former Republican political aide turned Silicon Valley manager working at Netscape, and Scott McDonald, a software developer.[7][1][8][9] AllSides uses a "multi-partisan" methodology first developed by conservative professor Timothy Groseclose and his collaborator Jeffrey Milyo.[10] AllSides partnered with activist Joan Blades to launch a classroom program, AllSides for Schools,[11] and has partnered with other organizations to provide programs such as Mismatch, a platform to connect users who differ politically and geographically.[12][13]
