Closer is a platform for regenerative communities that combines operational tools with governance infrastructure. It offers booking and calendar management, events and ticketing, subscriptions and payments, inventory and resource management, learning and knowledge sharing, RESTful API access, and token-enabled governance features such as voting, Proof of Presence, and Proof of Sweat. Closer also develops Closer Agent, a sovereign AI system for community knowledge and task management that runs on community-controlled infrastructure and is currently in alpha. The platform serves regenerative villages, intentional communities, and organizations managing shared spaces, resources, memberships, and participatory governance.
