An AI chief of staff is an AI agent that keeps a leadership team's work moving. It sorts what comes in, turns real asks into tasks with an owner, hands work to the right person or agent, follows up and briefs you. Ours works for VantaSoft's three owners. It prepares and drafts, and leaves money, outside messages and calendar commitments to us.
VantaSoft runs on a team of 13 AI agents that work alongside the company's three owners. Most of the agents belong to one department, such as finance, content or engineering. Vance, our chief of staff agent, works for the owners themselves. This is what he did in the 30 days to October 30, 2026.
| What he did in 30 days | Count |
|---|---|
| Emails he read, labeled and summarized for our CEO | 2,505 |
| Emails that became a task on the CEO's list, linked back to the email | 304, about 1 in 8 |
| Jobs he handed to other agents on our shared task board | 18, spread across 9 agents |
| Of those 18 jobs, finished | 13 |
| Of those 18 jobs, waiting on an owner's decision, approval or files | 3 |
| Of those 18 jobs, withdrawn | 2 |
Handing work to other agents sounds like the heart of a chief of staff's job, yet it came to 18 jobs in a month. Most of his day protects the owners' attention. He sorts what comes in so that only what needs one of us reaches us, and he keeps track of what is still open.
What does an AI chief of staff do all day?
Ours spends most of the day reading and sorting, and a small part handing work out. He checks the CEO's inboxes every half hour, keeps the task list numbered and current, sends a morning rundown and gathers progress from other agents before the monthly board meeting. The table shows a normal week and what reaches an owner.
| When | What he does | What reaches an owner |
|---|---|---|
| Every 30 minutes | Reads new email in the CEO's inboxes, labels each one and writes a one-line summary | A short alert in a private channel, plus a task when the CEO owns the next step |
| Every 5 minutes | Gives each new task a short number, such as T-13 | Any owner can write "T-13" in chat, and the agents can look up exactly which task he means |
| Weekday mornings | Sends a rundown of the day's meetings | One message before the day starts |
| Every morning | Adds the day's recurring to-dos to the task list | Only to-dos the CEO has to do himself |
| Monday, Wednesday and Friday | Lists local business networking events in the next 30 days | A short list for the owner who runs sales |
| The day before a company holiday | Posts a heads-up in the company channel | Nobody is surprised by a closed office |
| Before each monthly board meeting | Asks each agent for progress and drafts that meeting's section of the board notes | A prep brief for our COO |
| Fridays | Checks the agents' files and settings for security problems | A short report of what changed |
Email is where the volume is. In those 30 days, one email in eight turned into a task. The rest got a one-line summary and nothing on the list. When the CEO answers an email himself, Vance closes the task it came from, so the list does not fill up with finished work. Our step-by-step guide to building an AI email triage system covers that part, and our post on our AI scheduling assistant covers the morning rundown.
The board notes follow one rule we care about. When an agent does not answer in time, its line in the draft reads "(no update received)." He leaves the gap visible instead of filling it with a guess, because the owners would rather see a blank than read progress nobody reported.
The task numbers sound minor. They let an owner write "T-13 is done" and nobody has to ask which task he means. The list has handed out 412 numbers since we started numbering on September 25.
What does an AI chief of staff hand back to the owners?
Anything that spends money, speaks for the company to outsiders, commits someone's time or cannot be undone goes back to an owner. Ours drafts the email, lays out the full calendar invite or prepares the payment link, then waits. With three owners, a yes from any one is enough, and each decision goes to the owner who runs that area.
| He does on his own | He prepares it, and an owner decides |
|---|---|
| Read, label and summarize email | Send any other email outside the company |
| Reply "You're welcome!" to a note that is only a thank-you | Create or change a calendar invite |
| Add, number and close tasks | Spend or move money, apart from one small errand an owner approved in advance |
| Hand a job to the right agent | Send a message to many people at once |
| Ask other agents for progress and post routine team notices | Make a legal decision, or do anything that cannot be undone |
The two exceptions in that table are standing approvals. The CEO decided once that a plain thank-you deserves a short reply without a draft, and that one repeat errand could be paid for without asking. Each one is written down and covers that single action only.
Two more rules make the job work with more than one owner. Nobody has to collect three approvals, so a draft does not sit waiting for the slowest reply. When two owners' instructions conflict, he does nothing that cannot be undone and asks them to settle it rather than picking a side himself.
Who decides what is written down too. Each owner has the final say in the departments he runs, so a pricing question goes to the owner who runs pricing, not to the CEO by default. We learned that one the hard way, and our post on what 101 handoffs from our agents to people taught us tells the story.
Most of the value sits in preparing right up to the line. When a customer signs an agreement that calls for a payment link, sending that link is the next step, and he does not wait to be asked. For our own agent service, he creates the link from the signed terms and leaves the email that carries it in the CEO's drafts. All that is left for a person is to read it and press send. Our guide to human in the loop for AI agents covers how to choose which actions get an approval step.
What did we take off our AI chief of staff's plate?
We took two jobs away from him, both because sending them through him added a step. Since October 13, email about our active projects goes straight to our project manager agent, who reads those inboxes himself. Since October 17, any agent can hand its own work to another agent. Vance still sets up every new agent we add.
The owners also go straight to the specialist agent when the job is obvious. A question about an invoice goes to the finance agent, and a blog question goes to the content agent. Vance takes the work with no clear owner and the work that crosses departments.
For an owner setting one up, that is the part to copy. Give the chief of staff the work nobody else owns, and let people go straight to the specialist when the owner of a job is obvious. If the chief of staff is the only way in, every request ends up waiting on one agent.
Is an AI chief of staff the same as an AI executive assistant?
Not quite, though in a small company one agent can do both. An AI executive assistant looks after one person's inbox and calendar. An AI chief of staff looks after the gap between a decision and finished work, across the leadership team. Ours does both, because a company our size has no separate assistant.
| AI executive assistant | AI chief of staff | |
|---|---|---|
| Works for | One person | A leadership team, or one owner across the whole business |
| Looks after | That person's inbox, calendar and errands | What came in, who owns it, and what is still open |
| Hands work to | Rarely anyone | People and other agents |
| What you get | Replies, bookings and reminders | Tasks with owners, briefings and follow-ups |
Anthropic uses the term the same way. In a report on how work is changing inside the company, published October 16, 2026, Anthropic describes an executive assistant who built an agent for scheduling and email triage and then moved on to "higher-order 'chief of staff' tasks." The same report mentions an engineer who "set up an agent chief of staff to triage agent requests."
Ours cannot do the part of a human chief of staff's job that rests on relationships. He does not sit in meetings, push back on an owner face to face or settle a disagreement between two people, so that work stays with the owners.
How do you set up an AI chief of staff for your business?
Write a short charter before it starts. It should say who the agent works for, who decides what, what it can read, what it does alone, what it drafts and waits on, where tasks go, when it briefs you, how you correct it and what you check after 30 days. Copy the left column below and write your own answers.
| Charter line | Our answer |
|---|---|
| Who does it work for, and who breaks a tie? | Three owners. Any one can approve. When two disagree, it holds off on anything permanent and asks them to settle it. |
| Who decides what? | Each owner has the final say in the departments he runs. Decisions go to that owner. |
| What can it read? | The CEO's inboxes, calendars and task list, the agents' shared task board and our internal notes. |
| What does it do alone? | Sort and summarize email, add and number tasks, hand jobs to agents and ask them for progress. |
| What does it draft and wait on? | Outside emails, calendar invites, payment-link emails and anything permanent. |
| Where do tasks go? | The CEO's list holds only what he must do himself. Agent work lives on the agents' board. |
| When does it brief you? | Weekday mornings, short alerts through the day, and before each board meeting. |
| How do you correct it? | Each correction becomes a written rule, with a date, in its job description. |
| What do you check after 30 days? | Emails sorted against tasks made, jobs waiting on an owner, and anything that slipped. |
The task line keeps the owner's list readable. When agents park their own work on it, it grows faster than anyone can read it, so the CEO's list holds his next steps and the agents keep their work on their own board.
Write corrections down. Vance's written job description holds about a dozen dated standing rules, and more than half were added right after one of us corrected something he did. They run from sending a short email reply with every calendar invite to which owner gets a given decision. A correction said once in chat can get lost. A written rule is there every time he starts work.
What does an AI chief of staff cost?
There are two costs: what you pay for the agent, and the time the owners spend answering it. A done-for-you agent from VantaSoft starts at $1,000 for the build, paid once, plus $200 a month for hosting and maintenance, per our pricing page on October 30, 2026. Owner time is harder to price, so count it from week one.
Our month gives a sense of that second cost. Three of the 18 jobs Vance handed out were waiting on an owner's decision, approval or files. That time is part of what any agent costs, the same way managing a new hire is part of what the hire costs.

Frequently asked questions
What is an AI chief of staff?
An AI chief of staff is an AI agent that keeps a leadership team's work moving between a decision and the finished job. It sorts incoming email and requests, makes tasks with an owner, hands work to people or other agents, follows up and sends briefings. People approve anything that spends money, speaks to outsiders or cannot be undone.
Can one AI chief of staff work for more than one owner?
Yes, as long as you write down who decides what. Ours works for three owners. A yes from any one of them is enough, each owner has the final say in his own departments, and when two of them disagree, the agent holds off and asks them to settle it.
Can an AI chief of staff send emails or book meetings for me?
It can, if you let it. Ours sends one kind of email on his own: a one-line "You're welcome!" to a person whose latest note is only a thank-you, which the CEO approved in advance. Every other outside email is a draft, and every calendar invite is shown in full and waits for an owner's yes.
Do you need a big company to use an AI chief of staff?
No. Ours works for a company with three owners and no separate assistant. A small team can get a lot from one, because the owners are the people every decision waits on. Start with one loop, such as email that turns into tasks or a morning rundown, and add the rest once that loop runs well.
How is an AI chief of staff different from ChatGPT?
ChatGPT answers when you ask it something. A chief of staff agent works on a schedule, with access to your inbox, calendar and task list, and takes the next step without being asked, inside the limits you set. Our comparison of an AI agent vs a chatbot covers the difference in more detail.
