tersOS runs a coworking space from one system: room and desk bookings, memberships and invoicing, a member app for iOS, Android and the web, community feed and chat, a live floor plan, screens on the walls, events, a shared inbox and CRM, newsletters, and tersAI, an assistant that answers questions and books rooms for staff, members and visitors. It is built by the team that runs tershouse, a coworking space in Sarajevo, and runs that space every day.
