As access to and affordability of mental health treatment is a major issue in Thailand (1 psychiatrist per 250,000 people), we are utilizing the WHO optimal mix of services as a guide to identify the optimum solution possible given the circumstances. Sati App is positioned as an application that provides "on-demand listening" or peer support to anyone experiencing distress and in need of assistance. We are collaborating with the government, private sector, and public sector to ensure that the service is delivered at no cost in order to reach the greatest number of people possible.
