Kustos Ry is a public administrative network for Finnish in-house companies. Our goal is to secure and promote their business opportunities and welfare. Domestic in-house companies owned by public administration organizations are procurement units whose mission is to enable the best services for their owners. The companies significantly purchase services from the private sector, thereby strengthen the domestic regional and local economy. In addition, in-house companies maintain the security of society's supply, ensuring the operation of affiliated units also in crisis situations.
