Shadow AI is real. The policy is one page.
Marketing is using ChatGPT for copy. Sales is using an agent for follow-up. Support is testing a triage tool. None of it went through you. None of it has a documented approval point. Then a customer asks why the response they got sounded like AI. You realise you cannot answer who decided to send it.
AI mistakes are owned by the deployer of the decision. The tool does not absorb accountability. The founder does, by default, when no policy exists.
