Chief of Staff vs Executive Assistant: Which Does a CEO Need?

At some point a CEO looks at the week ahead and decides they need a senior person next to them. Then the job title gets fuzzy. One advisor says hire an executive assistant. Another says you have outgrown that and need a chief of staff. A recruiter sends a job description that asks for both at once, at the salary of neither.

The two roles sound close because both sit next to the CEO and both see everything. They solve different problems. An executive assistant fixes how your time, inbox and commitments are run. A chief of staff fixes how the company's priorities get turned into finished work across teams.

I run Virtual Assistant Capital, where we match companies with dedicated remote assistants, including executive assistants. We don't place chiefs of staff, so I have a stake in only one side of this, and you should read me with that in mind. For many founders the honest answer is the EA first. For some it isn't, and I'll say how to tell. This guide covers what each role owns, how to read the signs in your own week, what each one costs, and how to avoid hiring a blurred version of both.

The short answer

An executive assistant works on the CEO's capacity. They own the calendar, the inbox, meeting preparation, travel, follow-through and the running of the CEO's day.

A chief of staff works on the company's execution. They run the leadership team's operating rhythm, drive projects that cross departments, prepare major decisions, and act as a thinking partner to the CEO.

A useful test: if the person left tomorrow, what would break first? If it is your week, that was an EA. If it is the company's priorities, that was a chief of staff.

Harvard Business Review made the case for the role in Dan Ciampa's "The Case for a Chief of Staff", whose subtitle is that CEOs need more support than an executive assistant can provide. That is true of some CEOs. It isn't true of every CEO, and a lot of founders read it before they have fixed the simpler problem.

The main differences

The last row is a common pattern rather than a rule. Plenty of chiefs of staff stay longer, and plenty of EAs grow into operations. It is still worth knowing, because a strong chief of staff usually wants a next step, and you should plan for that when you hire.

What an executive assistant actually owns

We have a full guide to what an executive assistant for a CEO should own, so I'll keep this short. The heart of the job is five things:

• Time. The calendar is protected, shaped and defended by rules you agreed.
• Information. Your inbox is triaged, so you see only what needs you.
• Meetings. You walk in briefed, and decisions come out with named owners.
• Relationships. Investors, board members and key customers don't get left waiting.
• Logistics. Travel, board packs and events run without you carrying the details.

Notice how much of this is about follow-through. A strong EA already gives you a light accountability system. Many CEOs who think they need a chief of staff are really missing that, because nobody tracks what got promised in Tuesday's meeting.

What a chief of staff actually owns

The role varies more than any other at this level, which is part of why it is hard to hire. Most versions include some mix of these:

• The operating rhythm. Quarterly planning, weekly leadership meetings, goal reviews, and making sure each of these produces decisions rather than updates.
• Cross-functional initiatives. The projects that belong to no single department: a pricing change, entry into a new market, a reorganization, an integration after an acquisition.
• Decision preparation. Taking a messy question, gathering the facts from several teams and putting a clear recommendation in front of the CEO.
• Communication. Board updates, investor narratives, all-hands content and the CEO's message to the company.
• The honest mirror. Telling the CEO what the leadership team won't, and telling the leadership team what the CEO actually meant.

That last point is the one that doesn't fit on a job description, and it is why the role depends so much on trust. A chief of staff has no team of their own and gets things done through influence. If your VPs don't respect them, nothing moves.

Six signs you need an executive assistant

• You spend real hours each week on scheduling, travel or email that someone else could do.
• You go into important meetings underprepared.
• People chase you for replies, approvals and introductions.
• You forget what you promised, and so do others.
• Your calendar has no focus time, and you do your thinking at night.
• You can name your priorities, but your week doesn't reflect them.

Each of these is a problem with how your time runs. None of them needs someone to rethink the company.

Six signs you need a chief of staff

• Your calendar and inbox are already well run, and you are still the bottleneck.
• Important projects stall between departments because nobody owns the gap.
• Your leadership meetings are status updates and few decisions get made.
• You have several direct reports and no one to prepare hard decisions with you.
• Board and investor work is eating the time you need for customers and strategy.
• The company has reached the size where you can't personally see everything, so you need someone who can.

The first sign is the most important one. If your day is still chaotic, a chief of staff will end up doing EA work at chief of staff prices, and they will not be happy about it. They will also likely leave.

Does company size matter?

It matters less than people say, but it is a fair starting point. These are my own rules of thumb, not research, so adjust them to your situation.

Solo founder to small team. You likely need a part-time or full-time assistant. There aren't enough cross-functional projects to fill a chief of staff's week, because you and two others can settle most things over lunch.

A company with a real leadership team. A strong full-time EA pays off here, because your time is now the constraint. If you have people running sales, product and operations, this is often the stage where the EA is most valuable.

Several layers of management, multiple offices or a board that expects a lot. This is where a chief of staff starts to earn the title. There is enough work between the departments to fill a job, and usually an EA is working alongside them.

The stage where founders make the wrong call is the middle one. They feel overwhelmed, they hear "chief of staff" at a conference, and they hire someone expensive to fix what is mostly a calendar and follow-up problem.

What each role costs

Executive assistant. The US Bureau of Labor Statistics puts the median annual wage for executive secretaries and executive administrative assistants at $76,590 in May 2025. That is salary alone. Payroll taxes, benefits, equipment and recruiting come on top. Our guide to what an executive assistant costs lays out the whole bill.

Chief of staff. I couldn't find a government wage figure for this title, and I won't quote a number from a recruiter's blog as though it were data. In practice the pay tends to sit above a senior EA's, and at larger companies it can move toward VP level, especially with equity. Our cost guide uses a rough planning band of $85,000 to $110,000 a year for senior EA and chief of staff level support in the US, and that is a market band rather than a survey. Expect a true strategic hire at a bigger company to cost more. Get real quotes for your city, whether that is Austin, Toronto, Sydney, Auckland, Dublin or London.

Remote executive assistant. Our pricing is published:

• Essentials, $899 a month: 20 hours a week, suited to a founder with a lighter load.
• Executive, $1,599 a month: a full-time dedicated virtual executive assistant.
• AI Manager, $2,599 a month: full-time and AI-fluent, for someone who also runs your AI-assisted workflows and keeps your CRM in shape.

All plans have a $0 recruitment fee, a free shortlist of two to three VAs in 72 hours, month-to-month terms and a 30-day replacement promise. You pay only once your assistant starts.

The cost difference is the practical reason to try the EA first. A month-to-month remote EA is a small, reversible test. A chief of staff is a senior hire with a long search and an awkward exit if you got the need wrong.

The hybrid trap

Many job posts say "EA / Chief of Staff". I understand why. A small company can't afford two people and wants one who does everything. Sometimes it works, usually with a rare person who is happy doing both for a while.

More often it fails in one of two ways. You hire a brilliant operator, and they resent booking flights within six months. Or you hire a brilliant EA, give them a strategic title, and they are left running cross-functional projects without the authority or the background to do it.

If you do want one person across both, be honest about the split. Write down what percentage of the week is support work and what percentage is project work, and pay for the more senior of the two. Then tell your leadership team what authority this person actually has.

A cleaner way to get there is to promote. A strong EA who has been in the room for a year or two knows your priorities better than any outside hire. Hand them one real project, see how they do, and let the role grow if they want it and are good at it. Some of the best chiefs of staff started this way, and it is a much safer bet than a job title on day one.

Can you run both?

Yes, and at a certain size you should. The clean split looks like this:

• The EA owns the CEO's time and the logistics of everything.
• The chief of staff owns the content of the priorities and the work across teams.

The EA books the board meeting, and the chief of staff writes the narrative. The EA protects your focus block, and the chief of staff decides with you what the focus should be spent on. Agree on who owns what early, because both will see the same inbox threads, and overlap here creates tension fast.

Should either role be remote?

An EA works remotely for most of the role. Calendars, inboxes, briefs and travel are screen work, and what matters is enough overlap with your hours and secure, delegated access. The same setup works for a CEO in Chicago, Vancouver or Melbourne.

A chief of staff is harder. The job relies on trust with your leaders and on reading a room, so if your leadership team is in one office, a chief of staff probably should be too. If your whole company is remote, a remote chief of staff is perfectly reasonable.

Where AI changes the picture

AI tools now write meeting notes, draft replies and summarize long documents. That takes hours out of both roles, and it raises the bar for each. An EA who uses these tools well can take on work that used to need someone more senior, such as a first draft of a board update or a research brief.

That is the thinking behind our AI Manager virtual assistant: AI handles the volume, and a person stays accountable for the result. It doesn't make that person a chief of staff. It does mean you can often go further with a strong EA before you need one, which is my opinion based on where the role is heading, not a measured result.

FAQ

Is a chief of staff higher than an executive assistant? Usually, yes, in pay and in scope. A chief of staff typically works at a senior level and takes part in leadership decisions, while an EA supports the executive directly. A very senior EA can still be more valuable to a CEO than a weak chief of staff.

Can an executive assistant become a chief of staff? Yes. An EA already knows the CEO's priorities and the company's people. The usual path is to take on one real cross-functional project, then more, with the title following the work. It suits EAs who want project ownership, and not all of them do.

Do I need a chief of staff or an executive assistant first? Most CEOs should fix their time first, so an EA usually comes first. If your calendar and inbox already run well and projects still stall between departments, you may be ready for a chief of staff.

What does a chief of staff do that an EA doesn't? They run cross-functional initiatives, shape the leadership team's agenda, prepare major decisions and act as a thinking partner to the CEO. An EA makes sure the CEO's time and commitments are handled.

Can a virtual assistant be a chief of staff? Not in the strategic sense. A remote assistant can handle the follow-through side, including action tracking and meeting preparation. We match assistants, not chiefs of staff, so if you need someone to run strategy across your leadership team, you should hire for that role directly.

How much does a virtual executive assistant cost compared with a chief of staff? With us, a full-time virtual executive assistant is $1,599 a month, with no recruitment fee and month-to-month terms. A chief of staff is a senior salaried hire, so it costs far more and takes much longer to fill.

The short version

An executive assistant runs your time, and a chief of staff runs the work between your teams. If your week is the problem, hire the EA. If your week is under control and projects still stall, look at a chief of staff. Avoid the blended job post unless you are honest about the split, and remember that a strong EA can sometimes grow into the bigger role.
