Runbook is an autonomous operations platform that turns how an operations team works into AI agents that run jobs end-to-end inside the systems the business already uses. Agents work across phone, email, SMS, Teams, Slack, web chat, ERP, CRM, spreadsheets, vendor portals, and legacy systems, including tools without APIs through browser automation. Teams describe a workflow in plain English and provide SOPs, training documents, call recordings, carrier rules, and work history so the agent learns how the operation actually runs, including edge cases and tribal knowledge. Rather than acting as a copilot, the agent owns the complete workflow, from the first inbound request through system updates and closure. It can automate appointment scheduling, accounts payable and receivable, order management, status updates, vendor coordination, calls, follow-ups, and system entries.
