We build a CFO agent named Charles, give him a team of specialist sub-agents (FP&A, Accounting, and Treasury), and watch the delegation logic in action as Charles routes questions to the right specialist instead of answering everything himself. Mike also breaks down how to use ChatGPT to write your own system prompts, why you should give the CFO a reasoning model while using cheaper models for the sub-agents, and how to publish the finished chat so your whole team can access it. By the end of this episode, you'll have everything you need to replicate this AI finance department in under 45 minutes.\n\nTimestamps\n\n00:00 – Intro\n\n00:03 – What we're building: AI CFO inside N8n\n\n00:23 – Mike's background and 100,000 hours of automation\n\n00:52 – Why N8n over Make, Zapier, or Power Automate\n\n02:00 – Setting up the chat trigger and naming the CFO\n\n05:00 – Using ChatGPT to write the CFO system prompt\n\n08:52 – Choosing the right AI model and saving on token costs\n\n13:27 – Building the FP&A sub-agent (and what FP&A actually does)\n\n16:36 – Adding the Accounting agent with code interpreter\n\n19:25 – Building the Treasury agent\n\n33:21 – Successful routing to FP&A and Treasury agents\n\n38:19 – Publishing the chat and embedding it in Slack, Teams, or a website\n\n39:22 – Mike's philosophy: train your team to build, don't just build for them\n\n41:14 – Where to find Mike and his free Finance Automation Insider newsletter\n\n\nKey Points\n\nUsing ChatGPT to write your own N8n system prompts is one of the fastest ways to get started — nothing knows ChatGPT better than ChatGPT itself, and what would have taken six hours of writing two years ago now takes minutes.\n\nThe delegation logic is non-negotiable.
