Chief of Staff has become one of the most popular and least consistently defined roles in startups.
At one company, the person is effectively the founder's strategic partner.
At another, they run key company initiatives.
Elsewhere, they own board preparation, fundraising support, hiring, operations and internal communication.
Sometimes they are doing all of those things.
Sometimes the role is really an Executive Assistant with a more senior title.
Sometimes it is the work of a COO that the company is not ready to name yet.
That ambiguity is not automatically a problem.
Early-stage jobs are often broad.
The problem begins when the founder cannot explain what leverage the person is meant to create.
"I need help" is not enough
Founders reach a point where there is simply too much happening.
Customer meetings.
Hiring.
Investor updates.
Planning.
Product decisions.
People issues.
Partnerships.
Internal communication.
Suddenly, a Chief of Staff seems like the answer.
It may be.
But "the founder is busy" is not a sufficient role definition.
Every good founder is busy.
You need to understand what kind of work is being lost because of that busyness.
Are strategic projects not progressing?
Are decisions failing to reach the wider company?
Does the founder spend too much time coordinating work between teams?
Is nobody preparing the information required for important decisions?
Does hiring keep getting deprioritised?
Are board and investor processes consuming too much leadership time?
The clearer the problem, the clearer the role becomes.
A Chief of Staff should create leverage, not dependency
The best Chiefs of Staff make the organisation more effective.
They should not simply make the founder more comfortable.
There is a subtle difference.
If every problem starts flowing through the Chief of Staff because nobody else knows where to send it, the role can become another bottleneck.
If the Chief of Staff becomes the only person who understands what the founder wants, communication becomes weaker rather than stronger.
Good Chiefs of Staff reduce unnecessary dependency.
They create clarity.
They help important work move.
They make sure decisions become action.
They connect things that would otherwise remain disconnected.
Eventually, some of the systems they build should operate without them.
Decide whether the work is strategic or operational
Chief of Staff roles often combine both.
But the balance matters.
A strategic Chief of Staff might work heavily on company priorities, board materials, market analysis, fundraising, special projects and executive decision-making.
A more operational Chief of Staff might own planning rhythms, cross-functional execution, internal communication and business operations.
Some are highly analytical.
Some are relationship-led.
Some effectively become the founder's extension across the company.
You need to know which capability matters most.
Hiring a former consultant because they are excellent at analysis may not help if the real problem is organisational coordination.
Hiring a brilliant operator may not solve the need for someone who can model strategic decisions and support fundraising.
The title does not answer the question.
The work does.
Do you need a Chief of Staff or an operator?
There is a point where startups use Chief of Staff as a catch-all title for unresolved organisational design.
That is worth challenging.
Perhaps you need a Head of Operations.
Perhaps you need an Executive Assistant.
Perhaps you need a Finance lead.
Perhaps you need a Talent leader.
Perhaps you genuinely need a COO.
A Chief of Staff is particularly useful when the problems cut across functions and sit close to executive decision-making.
If the responsibilities belong clearly inside one function, hiring directly into that function may create more accountability.
This is why role definition matters so much.
The broader the title, the easier it becomes to avoid deciding who actually owns what.
Trust matters more than almost anything
Chiefs of Staff often have access to information very few people inside the company see.
Board discussions.
Financial information.
People issues.
Fundraising.
Strategic disagreements.
Founder concerns.
That requires trust.
But trust should not be confused with similarity.
The founder does not need to hire somebody who thinks exactly like them.
In fact, that may reduce the value of the role.
A good Chief of Staff should be capable of challenging assumptions privately and representing decisions clearly once they have been made.
They need discretion.
Judgment.
Emotional intelligence.
The ability to understand which conversations belong where.
Those qualities are difficult to assess through a conventional interview alone.
Go deeper into how the person has handled sensitive situations before.
Avoid hiring for polish alone
Chief of Staff candidates are often impressive communicators.
Many come from consulting, investment banking, venture capital, strategy or other demanding professional environments.
That can be valuable.
It can also make interviews unusually polished.
Go beyond presentation.
Can they execute?
Can they follow something messy all the way through?
Can they work without a perfectly defined project?
Can they communicate with engineers in the morning and investors in the afternoon?
Can they identify when something is not worth doing?
Can they handle detail without losing the larger picture?
Can they disagree with a founder without turning it into a performance?
That is the job.
Give them a real organisational problem
A practical discussion usually produces better evidence than abstract questions.
Give the candidate context.
The company has three major priorities.
Engineering is behind.
A senior hire has fallen through.
The board wants an updated plan.
The founder is spending too much time in customer meetings.
Two teams disagree about ownership of an important initiative.
What do they do first?
There is no perfect answer.
You are looking for how they structure ambiguity.
Which questions they ask.
What they escalate.
What they delegate.
What they consider noise.
What they believe only the founder can solve.
That is much closer to the work than asking where they see themselves in five years.
Think about what happens after the role works
Chief of Staff is often a transitional position.
That can be a strength.
Some people move into operations.
Product.
Strategy.
Business development.
General management.
Leadership roles.
Others remain Chiefs of Staff as the organisation grows.
Discuss this early.
If the candidate expects the role to become COO within a year and the founder sees it as a long-term staff position, the mismatch will eventually surface.
The company does not need to promise a precise path.
It should be honest about the possibilities.
The founder has responsibilities too
Hiring a Chief of Staff does not work if the founder refuses to share context.
The person needs access.
They need to understand how decisions are made.
They need to know what the founder is worried about before those concerns become public priorities.
They also need space to develop their own judgment.
A founder who delegates tasks but not context has hired an assistant, regardless of the title.
A founder who delegates responsibility but continues to override every decision has created confusion.
The relationship requires deliberate work on both sides.
Hire one when coordination becomes a strategic problem
That is usually the point.
Not simply when the founder is overwhelmed.
Not because other startups have one.
Not because the title attracts ambitious candidates.
A strong Chief of Staff becomes valuable when important work repeatedly crosses organisational boundaries and the leadership team lacks the bandwidth to keep it moving.
They connect decisions with execution.
They create leverage around the founder without becoming a permanent layer between the founder and the company.
When that is the problem, the role can be transformational.
When it is not, a more specific hire is usually better.
