Polikatikia.gr brings together residents, building management administrators and professionals of any kind, by connecting them through the same platform. It provides automated building management (via algorithms and IOT) that minimizes the resources cost (time and money) needed to manage a building the traditional way. It maximizes the managing efficiency and gives the opportunity to residents to take part in the management processes. It connects everyone within the building via communities and with professionals needed for any kind of services. It grows from a platform tool to become a network of communities, based around buildings (residences or workplaces), that has the ability to self-manage the buildings and connect as many services the users need, bringing immediacy, efficiency and secure transactions.
