What makes a great Chief of Staff (and when you actually need one)

I need to be honest with you about something. When I first started seeing “Chief of Staff” titles popping up I realised that I watch way too many CIA/FBI/White House PEOC shows… But then the role was for startups across a whole range of business stages.

It felt like title inflation gone wild. Like calling yourself “Director of First Impressions” instead of receptionist, or “Chief Happiness Officer” instead of HR. The founder’s right-hand person used to just be called Sarah or Dave or “that person who somehow knows where everything is.” They didn’t need a title borrowed from the White House.

But after watching this role evolve over the past few years, talking to founders who swear by their CoS, and seeing the chaos that ensues when the wrong person gets hired into this role, I’ve completely changed my tune. The Chief of Staff position, when done right, isn’t vanity. It’s a secret weapon.

The question is: do you actually need one, or are you just hiring for problems you could solve other ways?

Let’s start with what a Chief of Staff actually is (and isn’t)

Before we get into whether you need one, let’s clear up what this role actually involves. Because there’s a ton of confusion, and a lot of it stems from the fact that the role is deliberately amorphous.

A Chief of Staff is not:

• An executive assistant with a fancy title
• Your future COO (though they might become one)
• A status symbol to make your startup look bigger
• A dumping ground for tasks you don’t want to do
• Your clone

A Chief of Staff is:

• Your strategic thought partner who complements your gaps
• The person who buys back your time by taking ownership of cross-functional initiatives
• Someone who can operate at 30,000 feet one minute and in the weeds the next
• The translator between your vision and your team’s execution
• A force multiplier for founder bandwidth

Primary VC describes the best alternate titles for Chief of Staff as “Head of Leverage,” “Information Grand Central Station,” and my personal favorite: “Repository for Misfit Projects.”

That last one is actually more insightful than it sounds. A great CoS thrives in the gaps. They own the projects that don’t fit neatly into any one function. The cross-functional initiatives that would normally die in no-man’s land between Product, Sales, and Ops.

Think of them less as “Chief of Staff” and more as “Chief Leverage Officer for the Founder,” as Crane Venture Partners puts it.

The four types of Chief of Staff (and which one you actually need)

Not all Chiefs of Staff are created equal. Bain Capital Ventures breaks down four distinct archetypes, and understanding which one you need is half the battle.

The Operator

This CoS is all about execution. They take strategic direction from you and turn it into reality. They’re the person who takes your board meeting action items and actually makes them happen. They build systems, create processes, and ensure things don’t fall through the cracks.

When you need this: Your company is scaling fast, you’ve got clear strategic direction, but execution is chaotic. Things are slipping. Follow-through is weak. You need someone to drive the operational engine.

Ideal background: Former project manager, operations lead, or consultant who’s transitioned to operator.

The Strategic Partner

This CoS is your thinking partner. They’re in every important meeting with you, challenging your assumptions, pressure-testing ideas, and helping you think through complex problems. They’re less focused on execution and more focused on helping you make better decisions.

When you need this: You’re facing big strategic questions. Should we enter a new market? How do we position for the next fundraise? What’s our three-year vision? You need someone to pressure-test your thinking.

Ideal background: Strategy consultant, former GM, or someone who’s been close to strategic decision-making at scale.

The Swiss Army Knife

This is the classic early-stage CoS. They do whatever needs doing. One day they’re prepping for board meetings, the next they’re solving a customer issue, the day after they’re helping with a product launch. Maximum flexibility, zero ego.

When you need this: You’re pre-Series A or early Series A. The team is small. Everyone wears multiple hats. You need someone who can context-switch like crazy and isn’t precious about what’s “their job.”

Ideal background: Early startup employee, generalist from consulting, or someone who’s already proven they can figure things out in ambiguous environments.

The Project Lead

This CoS owns specific high-stakes initiatives. Maybe it’s the fundraise. Maybe it’s launching in a new market. Maybe it’s a major product overhaul. They dive deep on one big thing rather than spreading across everything.

When you need this: You’ve got a specific, critical project that needs dedicated attention, but it doesn’t warrant a full department. It’s too important to be a side project for existing team members.

Ideal background: Someone with deep expertise in the specific area you need (fundraising, market expansion, M&A, etc.).

The mistake most founders make is hiring the wrong archetype for their actual needs. They hire a Strategic Partner when they actually need an Operator. Or they hire a Project Lead when they need a Swiss Army Knife.

When you actually need a Chief of Staff (the honest answer)

You probably need a Chief of Staff if:

Your calendar is a nightmare and you can’t think. If you look at your diary and it’s wall-to-wall meetings with barely any space for actual thinking or strategic work, that’s a red flag. Airtree Ventures points out that when you have only a “smattering of time to do other ‘real work’ and thinking,” it’s time to consider a CoS.

You’ve become the bottleneck. Everything flows through you. Decisions wait for you. Projects stall until you weigh in. Your team is frustrated because they’re blocked on you, and you’re frustrated because you can’t get to everything. A CoS can make decisions on your behalf, unblock teams, and keep momentum going.

You’re drowning in cross-functional coordination. You’ve got Product building something, Marketing preparing to launch it, Sales needing to sell it, and Customer Success preparing to support it. Getting all these functions aligned is eating your entire week. A CoS can own this coordination, run the cross-functional standups, and escalate to you only what actually needs your input.

You’re entering a high-intensity period. Fundraising is a perfect example. It can consume 85%+ of a founder’s time. During strategic growth periods like fundraising, a CoS can either run the business while you fundraise or actively help with deck assembly, investor materials, and communications.

Your leadership team needs alignment. You’ve hired great functional leaders, but they’re operating in silos. A CoS can facilitate leadership team alignment, run effective exec meetings, track OKRs across functions, and ensure everyone’s rowing in the same direction.

You’ve hit 100+ people. This is often the inflection point. Below 100 people, the founder can still maintain relationships across the org. Above 100, you need someone to be your eyes and ears, surface problems before they blow up, and ensure culture doesn’t erode as you scale.

You probably DON’T need a Chief of Staff if:

You really just need an Executive Assistant. If your main pain point is calendar management, travel booking, and inbox management, you don’t need a CoS. You need a fantastic EA. EAs are incredible and critical for growth. But they’re a different role with different compensation and different career trajectories.

You’re sub-20 people and pre-product-market fit. At this stage, everyone’s a Swiss Army Knife by necessity. The founder’s bandwidth issues are real, but they’re also inevitable. That salary might be better spent on engineering talent, your first sales hire, or marketing.

You’re hiring for status. If you’re thinking “it would make us look more legit to have a Chief of Staff,” stop. Nobody cares. And you’ll end up with resentment, redundancy, and an expensive mistake.

You want to hire a clone of yourself. The whole point of a CoS is to complement your gaps, not mirror your strengths. If you’re a product-focused founder, you don’t need another product person.

You can’t articulate what they’d actually do. “Figure it out” is not a job description. If you can’t define clear priorities, outcomes, and success metrics, you’re not ready to hire for this role.

What makes someone great at this job

The non-negotiables:

Context-switching superpower. One minute they’re in a board deck, the next they’re troubleshooting a customer issue, then they’re back to three-year strategy. They don’t lose the plot when jumping between altitude levels. This is probably the single most important skill.

Ego checked at the door. Crane VC nails this: “They don’t need to be the face, the star, or the founder’s shadow. They just need to win with you.” The best CoS leads from behind.

Bias for action. They solve problems without waiting for permission. They don’t bring you problems, they bring you solutions with a recommendation on which one you should pick.

Comfort with ambiguity. The role is deliberately unstructured. If someone needs clear swim lanes and defined responsibilities, they’ll struggle in this role.

Strong opinions, lightly held. They care deeply and have informed perspectives, but they don’t make it personal when you disagree or change direction.

Exceptional communication. They’re the translator between you and the team, between functions, between strategy and execution.

The “nice to haves” that become critical:

Product intuition, analytical rigour, operational instincts, and people radar. The best CoS can sense when something’s off before you can articulate it. They pick up on team dynamics, culture issues, and brewing conflicts early.

How the role actually differs from other positions

Chief of Staff vs. COO

A COO owns operations as a function. They have a department, direct reports, clear KPIs, and long-term accountability for operational excellence. A CoS is a proxy for the CEO on specific initiatives. They work across functions but typically don’t have large teams reporting to them. Many CoS become COOs eventually. But they’re not the same role.

Chief of Staff vs. Executive Assistant

An EA manages the executive’s time and logistics. Calendar, travel, inbox, expense reports. They’re tactical and focused on the CEO’s day-to-day efficiency. A CoS manages the executive’s priorities and strategic initiatives. Board prep, cross-functional projects, team alignment, special projects.

Chief of Staff vs. VP of Operations

A VP of Operations owns specific operational functions: supply chain, facilities, IT, maybe people ops. They build and scale these functions. A CoS is more horizontal — they work across functions on whatever’s most important, less about building a specific capability and more about driving alignment on priority initiatives.

Chief of Staff vs. Business Operations

BizOps typically focuses on data, analytics, planning, and optimising specific areas of the business. CoS is broader and more strategic, closer to the CEO, involved in more sensitive discussions, and handling more ambiguous problems that don’t fit neatly into any function.

The career path question (because it matters)

The CoS role typically only lasts 2–3 years. This isn’t a bad thing — it’s actually a feature, not a bug.

For the person: it’s an incredible learning experience. They get exposure to every part of the business, work directly with the CEO, build a broad operational playbook, and figure out what they actually want to do long-term.

For the company: you get someone highly motivated to prove themselves, build things, and earn their next role (either internally or externally).

Common career paths for great Chiefs of Staff: VP of Operations or COO, Head of a specific function (Product Ops, People Ops, Business Ops), Head of Special Projects, General Manager of a business unit, or founder (many CoS use it as apprenticeship for starting their own companies).

The key is being upfront about this. Bain Capital Ventures recommends quarterly professional development conversations about: (1) how they’re progressing toward longer-term goals, and (2) how they might achieve those goals within the company. If you try to keep a great CoS in the role forever, they’ll leave.

How to hire one (and not screw it up)

Define the archetype first. Go back to the four archetypes (Operator, Strategic Partner, Swiss Army Knife, Project Lead). Which one do you actually need right now? Be specific. Don’t say “all of them.”

Focus on complementary skills, not familiar ones. If you’re a technical founder, you probably want someone with go-to-market experience. The temptation to hire someone like you is strong. Resist it.

Look for track record of over-delivering. Ask for examples of times they over-delivered on projects they owned, then dig deep on the “how.” Generalist skills matter, but what really matters is someone who sees what needs doing and just does it.

Test for chemistry. This is the most important relationship they’ll have at your company, and you’ll work together constantly. If the chemistry isn’t there in interviews, it won’t magically appear on the job.

Set clear initial priorities. You can’t give them a perfect job description because the role is fluid. But you can give them clear priorities for the first 90 days — specific enough to evaluate performance but flexible enough to adapt.

Give them real access from day one. The mistake most founders make is ramping a CoS up slowly. A CoS without full context is useless. Give them everything and they’ll figure out how to help.

Red flags to watch for

• High ego, low energy. If they want credit, need to be in the spotlight, or don’t have the stamina to keep up with startup intensity, it’s not going to work.

• Can’t context-switch. If they need to “deep work” on one thing for hours without interruption, this role will frustrate them.

• Treats it as a stepping stone to “real” work. If they see this as a brief resume line before moving to what they actually want to do, they won’t invest enough to be effective.

• Brings problems without solutions. A CoS who constantly escalates decisions to you without thinking through options first isn’t doing their job.

The bottom line: It’s about leverage, not status

A Chief of Staff is one of the highest-leverage hires you can make at the right time in your company’s lifecycle. But it’s also one of the easiest to screw up.

The role works when you genuinely need someone to multiply your effectiveness, when you hire for complementary skills, when you give them real access and authority, when you’re clear about what success looks like, and when you help them grow toward their next role.

The role fails when you hire for status, when you treat it as a dumping ground for tasks you don’t want, when you hire too early before you have real leverage opportunities, or when you try to keep them in the role forever.

Before you post that job description, ask yourself honestly: do I need a Chief of Staff, or do I just need to get better at prioritisation, delegation, and saying no? Sometimes the answer is the latter.

But if you’re legitimately drowning in cross-functional coordination, becoming the bottleneck for everything, or entering a high-stakes period where you can’t afford to drop balls, then the right CoS isn’t a luxury. They’re a necessity.

Just make sure you hire the right person for the right reasons. Your future self will thank you.
