Rings is a relationship intelligence platform for businesses that win on their networks — investment firms, banks, recruiters, and BD and partnerships teams where relationships drive revenue. Rings unifies people, companies, communications, relationships, and deal activity into a live relationship graph. Use Rings to power custom apps, dashboards, workflows, artifacts, and AI experiences with your organization’s relationship intelligence. This documentation covers two primary ways to build with Rings:
  • REST API — programmatic read and write access to contacts, companies, processes, notes, activities, and relationship data. Use it to build custom apps, dashboards, workflows, analytics, and integrations directly on Rings data.
  • MCP server — connect Claude, ChatGPT, and other AI agents directly to Rings. Agents can search and reason over your network, prep meetings, update records, and use Rings data to build custom apps, dashboards, reports, and other artifacts on your behalf.
