I just built something insane in n8n :- an AI “Ops Brain” that can run an entire company from one inbox. One brain. Eight departments. 18 Task. Zero chaos. ✨ HR (resumes, onboarding, leave) ✨ Finance (invoices, reimbursements, summaries) ✨ IT (access, incidents, resets) ✨ Sales (lead scoring, proposals, deal steps) ✨ Support (ticket intent, replies, SLA alerts) ✨ Operations (vendors, logistics, planning) ✨ Marketing (captions, calendars, analysis) ✨ Compliance (policy checks, contract summaries) The architecture: → Gmail trigger receives request → CEO Brain classifies intent → Routes to the correct department agent → Agent calls the appropriate tool (18 n8n sub-workflows) → Returns structured output → Escalates to Slack if human review needed No hard-coded routes. No manual triage.
