About us

The Collective for Social Interventions (KOI) is a group that produces social critique aimed at achieving broader social change. Our activities consist of socially engaged research, political education, and publishing. We are committed to solidarity and social justice.

The non-governmental organisation was founded in 2013 when its members were still part of the initiative New Left Perspectives and the social center “Haspel” in Sofia. We maintain a partial archive of the initiative that was set up in 2011, which you can find here[1] .


KOI is a partner organisation of the Rosa-Luxemburg-Stiftung and the Clean Clothes Campaign.
