The Chief of Staff handbook

Ask five Chiefs of Staff what they did last week and you'll get five jobs. Some run the leadership meeting, the planning cycle and board prep for a whole company. Alexa Gellman, who was Chief of Staff to a managing partner at a New York venture fund when we spoke, spent most of her week on deals. And 12% of Chiefs of Staff start the role with five years of experience or less, according to the Chief of Staff Network's 2026 Pathways Report. Advice that describes one of those versions and calls it the job misleads the rest.

I became Chief of Staff to the CEO at Spring in 2016. [SCOTT: confirm the "wish I'd had it then" framing, and add one thing you learned the hard way in the first months.] This handbook draws on what the Chief of Staff Network has learned since 2017: salary surveys going back to 2019, the dated career histories of nearly 2,900 Chiefs of Staff, more than 1,800 job postings from 2026 and more than a hundred podcast conversations with people doing the work.

What is a Chief of Staff?

A Chief of Staff is the primary strategic operator reporting directly to one senior leader, called the principal, and acts as that leader's trusted advisor and right hand. The tasks vary by company, and four core responsibilities sit underneath them everywhere.

We built the four from what more than 1,800 job postings ask for. Priorities and decisions: what reaches the leader, and preparing the decisions that matter. Running the operating rhythm: the meetings and reviews where a leadership team decides things once. Communication up and down: honest information travelling up and clear decisions travelling down. Cross-functional projects: the important work that belongs to no team, run until it can be handed off. When the role works, the leader gets hours back every week and decisions stop waiting on them. The full model, with the posting data and where the role stops, is in what a Chief of Staff does.

Two boundaries confuse people most. An executive assistant manages the leader's time and logistics; a Chief of Staff manages priorities and decisions. A COO owns operations through a team and a budget; most Chiefs of Staff own neither. Our comparisons with the executive assistant and the COO draw each line with pay and tenure data.

What types of Chief of Staff are there?

The role takes its shape from who the principal is, how large the company is and what the leader needs most this year. Fewer than half of the postings that name a principal say the CEO.

At a startup the role absorbs whatever has no owner yet. At a large company it's narrower, more defined and often one of several Chiefs of Staff.

Why the principal sets the shape

A Chief of Staff has no authority of their own, so the edges of your job sit exactly where your principal's do. A CEO's Chief of Staff can launch a company-wide planning cycle; a CTO's Chief of Staff runs the same rhythm inside engineering and has to negotiate with peers, sometimes the CEO's own Chief of Staff, for anything that crosses that line.

The job also moves when the principal does. Yorm Ackuaku supported four executives at Weight Watchers in a little over three years, with priorities changing almost every quarter. Nobody wrote "protect the culture" into her job description. After enough handovers she noticed nobody else was watching what people experienced day to day, so she took it on.

How to tell which version you're in

Answer three questions in your first two weeks, or before you accept an offer.

1. What does your principal own, and what don't they? Write down the two or three decisions in their remit you'll prepare most often. Anything outside that list needs someone else's agreement.
2. Is there another Chief of Staff? Find them in week one and agree who runs what where your lines meet.
3. What does the leader need most this year? A planning reset, a fundraise, a merged organization or a team doubling in size each pull the week toward a different core responsibility.

The common mistake is running a functional role as if it were the CEO's: you launch a company-wide process, and the first sign of trouble is a peer asking who agreed to it. Also watch for an unnamed principal. Most postings (59%) don't say who the role supports, and if the answer on the first call is "a few leaders," I'd price and scope it as a project role.

In a remote role (21% of 2026 postings), the weekly note does work a hallway conversation would do elsewhere. Our Archetypes Framework names the common patterns.

My advice: choose the principal before you choose the company. A strong principal at an ordinary company will grow you faster than a weak one at a famous name, so ask what happens to the role if your principal leaves.

What changes across the six levels?

Decision rights change across the six levels. Our Leveling Framework runs from Analyst/Associate to CXO, and one question tells the levels apart: does this person carry out decisions, shape them or make them?

The biggest pay step is the move into Manager, about $33,000 in average base. The step from Manager to Director, about $29,000, is where the role shifts from getting things done for the leader to deciding what gets done.

How to read an offer against the levels

Decision rights set the level because they set the cost of a wrong call, and the market pays for that exposure. In 2026 postings, a plain "Chief of Staff" title has a median advertised salary of $174,000. Titles that add VP, Director or Head reach $230,000, and Chief of Staff plus Strategy roles $250,000, according to the Chief of Staff Network's 2026 Pathways Report.

Here's an illustration. A Series B company offers you "Chief of Staff to the CEO" at $150,000. In the final interview you ask which decisions you'll make without checking, which you'll recommend and which you'll only carry out. The answers: you'll run the leadership meeting agenda and the planning calendar, you'll draft the board deck for the CEO to rewrite, and nothing is yours to decide yet. That's Manager work, with a $144,464 average, so the offer is fair. If the CEO also wants you to decide which projects get staffed each quarter, that's Director work ($173,667), and you should say so before you sign.

Go by the decisions you'll own, since a "VP, Chief of Staff" at a 30-person company can be doing Manager work. And settle the level at the offer: only about 8% of completed Chief of Staff stints end with a bigger Chief of Staff title at the same company. If the company won't, write the decisions that would trigger a re-level and the review date into your mandate. Our guide to Chief of Staff skills shows what each level demands.

What does a Chief of Staff do each week?

Most weeks run on a fixed rhythm agreed with the principal: a prep block before the leadership meeting, the meeting itself, a standing one-to-one and a pass over what's slipping. Everything else, from a board deck to a reorg, fits around those fixed points.

Put the leadership meeting, the one-to-one and the weekly note on the calendar first; the rest of the week fits around them.

Without it, decisions get remade every week. Operating cadence, OKRs and KPIs are the most common responsibility in job postings, named in 61% of the more than 1,800 in the Chief of Staff Network's 2026 Pathways Report. Shelby Sly, Chief of Staff at Ridgeline, fixed hers as the company grew from about 200 people to more than 450 by cutting meetings with no clear outcome and moving status updates into writing, as she explains on our episode about moving to an async culture.

What does a Chief of Staff earn?

The average Chief of Staff base salary is $167,954 and the median is $160,000, according to the Chief of Staff Network's 2025 Salary Report (nearly 500 respondents). Level and company size move pay more than anything else.

Level more than doubles base pay from bottom to top, as the table above shows. Chiefs of Staff at companies with 5,001 to 10,000 employees average $217,385, against $141,705 at companies with 11 to 50. The gap between the best- and worst-paying industries is about $45,000, smaller than the gap between levels.

Among US Chief of Staff postings that list pay, the median advertised salary is $180,000, with a typical band of $150,000 to $200,000, according to the 2026 Pathways Report. That makes the Chief of Staff the best-paid operator role in the data outside AI leadership.

Our survey numbers are base pay only, so they look lower than "total pay" figures elsewhere. The Chief of Staff salary guide has every cut, from city to equity, with worked offers.

How do people become a Chief of Staff?

Most people become a Chief of Staff after about a decade of operating work. The median Chief of Staff starts with around 11 years of experience, according to the Chief of Staff Network's 2026 Pathways Report, and the backgrounds are broader than job postings suggest.

Operations (21%), sales (10%) and marketing (9%) each produce more Chiefs of Staff than consulting (7%) does, yet 27% of postings ask for consulting experience. If you're an operator without that background, you're the norm.

Most hires come from outside (64%, according to our 2024 hiring data), and the outside routes are often personal. Sharlene Guiriba moved from venture capital by asking investor friends which of their portfolio companies they believed in most were hiring; one introduction led to her role at Coverdash, as she describes on our episode about moving from VC to Chief of Staff.

The full playbook is in how to become a Chief of Staff. Our resume examples show how to write operating results, and new roles land on our job board every week.

What should you do in your first 90 days?

Listen first, then take ownership, then prove the role. Spend month one learning how decisions get made and taking one real task off your principal's plate, month two owning part of the rhythm, and month three running one strategic project.

The mandate is the piece most new Chiefs of Staff skip, and without it your scope becomes whatever was asked most recently. It's one page: why the role exists now, ranked priorities, three six-month outcomes, your decision rights and a review date. Our first 90 days guide has the listening tour questions and a day-30 memo, and the mandate guide has the template.

What's hard about the job?

The hardest part of the job is doing high-stakes work that no one can see, in a role whose edges were never written down.

Three problems come up again and again in our community. An unclear role means you get told off for doing too much one month and too little the next; our salary reports have long tied unusually wide pay at the Manager level to it. Invisibility means nobody notices who runs the machinery when it runs well, so promotion cases stall. And with no team, every new responsibility lands on one calendar.

When Chiefs of Staff in our 2025 Salary Report named what would make them leave, the top answers were bad management (14.5%), pay (13.7%) and lack of advancement (13.4%). Write the mandate so the edges are visible, send a weekly update so your work is on the record every Friday, and renegotiate scope at your six-month review, or sooner if it has doubled. The longer an informal scope runs, the more it looks like the job you agreed to.

Renegotiate or leave?

When the job goes wrong, renegotiate first. Chiefs of Staff who stay at the same company step up on their next move 61% of the time, against 48% for those who leave, and people who leave inside a year step up only 38% of the time, according to the Chief of Staff Network's 2026 Pathways Report.

The conversation works when the problem is the edges of the role and the principal still wants it to succeed. Three signs tell you which situation you're in.

To renegotiate, bring a one-page draft to your one-to-one: what you're doing today, what was agreed, the two or three decisions you need to own and what you'll hand back. Ask your principal to announce any new decision rights to the leadership team, because if you announce them, peers read it as a land grab. In the first month the work you handed back will drift back to you; redirect it every time. By month three, check whether decisions you now own are still being reopened in the leadership meeting.

A new principal resets all of this. When the leader changes, the old mandate stops binding anyone, so write a fresh one within the new leader's first month.

How long do people stay, and where do they go next?

Most Chiefs of Staff stay about two years and leave more senior than they arrived. The median completed stint is 20 months, with the middle half running 12 to 30 months, and 53% step up on their next move, according to the Chief of Staff Network's 2026 Pathways Report, based on more than 1,200 moves with rank stated before and after.

The odds of a step up peak at two to three years. Staying past three years pays in another way: the share whose next role is VP or above rises to 35%.

Founding is the fastest-growing exit: 1.8% of moves in 2020, 10.4% in 2025. And 78% of Chiefs of Staff change function across the role, which makes it one of the few reliable ways to switch careers at a senior level. Our Pathways report maps a typical route for each destination, and Chief of Staff vs COO covers the most-asked-about one.

How is AI changing the role?

AI makes the Chief of Staff more valuable, because AI is only as good as its context and the Chief of Staff holds more of a company's context than anyone except the principal. Drafting and summarizing get cheaper. Knowing what the leader wants and where the company disagrees stays scarce, and that knowledge sits with the Chief of Staff.

The status deck, the meeting notes and the first draft of the update are moving to tools. What's left is deciding what the leader should see and checking tool output against what's actually happening. One in four Chief of Staff postings asks for AI skills, according to the Chief of Staff Network's 2026 Pathways Report. In our 2025 Salary Report, Chiefs of Staff who describe themselves as AI-first average $189,128 in base pay, against $148,999 at the least AI-mature end.

Our guide to AI and the Chief of Staff covers workflows, policy and governance, and the Chief of AI Fellowship is our program for Chiefs of Staff who want to lead adoption.

How do you hire a Chief of Staff?

Hire one when you've become the bottleneck, then write down what the role will own before you write a job post. I'd put more failed Chief of Staff hires down to skipping that step than to anything else, because "help me with everything" gives neither side a way to tell, six months later, whether it worked. Write down what the hire should give back in six months too (hours of your week, decisions that stop waiting, one project shipped), because that's how you'll judge the salary.

Set the level from the decisions on that page and the pay from the level. Drop the consulting requirement, since operations, sales and marketing each produce more Chiefs of Staff than consulting does. Our guide to how to hire a Chief of Staff covers scoping, sourcing, interviews and onboarding, and the job description guide has a template and three examples. When you're ready, post the role on our job board or reach candidates through our talent network.

How do you know a Chief of Staff is working?

You know it's working when fewer decisions wait on the leader and the same decisions stop coming back. A good Chief of Staff makes the principal's week quieter and the company's priorities clearer within two quarters.

Check four things at the six-month mark. Are the outcomes in the mandate met or visibly moving? Does the leadership meeting decide things once, with owners and dates that hold? Does the principal hear bad news early and from the Chief of Staff? And has at least one cross-functional project, like a planning cycle, a reorg or board preparation, become something that runs without you? Board and investor work appears in a third of Chief of Staff postings (33%), so it's often the clearest place to see the difference.

If most answers are no at six months, rewrite the mandate with your principal before you start looking for another job.
