I kept noticing the same thing. Every decision, every piece of context, every "which prompt do I use for this" ran through me. I was the only one who knew how the whole business fit together, so I was the only one who could move any of it forward.
At some point I realized the problem was not the AI. The AI could do the work. The problem was that I had never actually built a team. I had never given anyone a name, a lane, or something they owned.
So I built it. Marketing has a name and a lane. Sales knows what a warm lead looks like. Operations handles the stuff I hate dealing with. Client Delivery thinks about the experience. My PA keeps me focused.
Now I direct the work instead of carrying it. Each agent knows the business and owns its lane, so the load is off me and the work gets better.
