There's a class of work that almost nobody tracks: the prep.
The time someone spends going through emails before a meeting. The research on who you're about to sit across from. The summary of where a deal or project stands. The briefing document that lets a busy executive walk into a room already knowing what matters.
Most senior people have someone doing this for them. A chief of staff. An executive assistant. Someone whose job includes knowing what you need to know before you need to know it.
I was sitting with a client who runs a membership club in Austin. Packed schedule. Lots of meetings. We started adding up how much time his team was spending each week just getting him ready.
The number was around 20 hours.
What That 20 Hours Looks Like
It's not one person sitting down for a 20-hour shift. It's accumulated time.
Someone pulls the email history between their boss and the person they're meeting tomorrow. Someone checks the CRM for context. Someone summarizes the last three touchpoints. Someone puts together a one-pager so the boss can read it on the way to the meeting.
Multiply that across a full week of meetings — six, eight, twelve a week for a busy operator — and you're looking at something like half a full-time employee, just for prep.
Most people don't think about it this way because the cost is distributed and invisible. But it's real.
What the Digital Chief of Staff Does Instead
I built something I call a Digital Chief of Staff. It's a bundle of AI agents that collectively do the same job — briefings, context gathering, meeting prep — automatically.
Every morning, the system generates a briefing document. Every meeting on the calendar gets a section: who you're meeting, what you've discussed before, what context from email and CRM and prior conversations is relevant to this conversation.
My client reads it in 15 minutes. He walks into every meeting with the same level of preparation that used to take his team 20 hours to produce.
A friend of mine, Evan, has a version of this too. His runs twice a week. In addition to the text briefing, it produces a visual — an image that maps out the week at a glance, who he's meeting and when, built with Nano Banana image models. He told me it changed how he shows up to meetings. Not just the prep time. The quality of attention.
The Part Nobody Talks About
There's a lot of AI content about writing. Coding. Research. Summarization.
There's very little about what I think is the highest-ROI use case for most people: just knowing what's happening in your own schedule.
It sounds basic. But most people walk into meetings carrying only the context they happened to remember. They do a quick Google search on the way over, or skim the email thread for two minutes in the parking lot. If there was a relevant conversation three months ago, they probably don't remember it.
The briefing doc fixes this. It gives you a complete picture before you need it. And the people on the other side of the meeting notice — not because you tell them about the AI, but because you show up prepared in a way that feels unusual.
One of my AI consulting clients told me the automated follow-up emails it generates — sent three minutes after a call ends — create more trust than anything else he's done. People message him asking how it's possible. Most people take days. He responds in minutes.
The briefing is the same category of thing. It creates a level of attentiveness that used to require a large support staff. Now it requires a few agents and some setup time.
Who This Is For
This isn't just for executives with packed schedules. It's for anyone who regularly meets with people and needs context to make those meetings count.
Sales reps who need to know what happened on the last three calls before they pick up the phone. Consultants who juggle multiple clients and can't remember every conversation. Business owners who are networking constantly and want to walk into every coffee chat knowing something useful about the person across from them.
The barrier to setting this up is lower than most people think. The hardest part is usually the CRM — getting your contact and conversation data into a place where the AI can access it. Once that's done, the briefing generation is relatively straightforward.
What 20 Hours Back Actually Means
When I told Cam and Dan — the clients I was demoing this for — that the briefing prep used to take 20 hours and now happens automatically, Dan said something I keep coming back to.
“It's not really about the 20 hours. It's about what you stop worrying about.”
He was right. The value isn't just the time. It's the mental weight of knowing you're always prepared. Of not having to wonder whether you missed something important in the email history before a call.
That's what an actual chief of staff gives you. And now it's what the digital version gives you too.
