Since its founding in 2015, ProjectTogether has accompanied more than 2,000 social initiatives and impact start-ups and involved tens of thousands of citizens, 8 federal ministries, 11 state governments and 60 municipalities in 10 innovation programmes and participation processes such as #WirVsVirus and UpdateDeutschland. Several times, the German government took over the patronage for ProjectTogether's activities, most recently in 2022 for Alliance4Ukraine. ProjectTogether also runs the Farm-Food-Climate Challenge and Circular Futures. ProjectTogether works at the intersection of civil society, government and business on the question of how to bring hundreds of actors into joint collective action on major societal challenges.
