The paper explores the connections of the processes of social enterprise (SE) development and
deinstitutionalization of mental health services in Ukraine. The author argues that mental health social
enterprises in Ukraine are developing under the influence of hybridized American-European SE cultures.
The development precedes the process of deinstitutionalisation of mental health in Ukraine which leads
to the unsustainability and fragility of social enterprise development in Ukraine. At the moment, SE
development in Ukraine is a mechanism of temporal sustainability of existing programs for mental health
users and support of local communities.
