What Does a Chief of Staff Do? Role, Responsibilities and When to Hire One
What Is a Chief of Staff?
A Chief of Staff is a senior leader who works directly with the CEO or another senior executive to drive priorities, coordinate the leadership team and make sure strategy turns into action. The role sits at the centre of the business, connecting the executive's agenda with the work happening across every function.
The position has long existed in government and the military, and it is now well established in businesses in London and the US. Founders, CEOs and managing partners increasingly see a Chief of Staff as a way to extend their capacity without adding another layer of hierarchy.
Because the role varies from one organisation to the next, employers often ask what a Chief of Staff actually does and when the business needs one. This guide answers both questions.
What Does a Chief of Staff Do Day to Day?
A Chief of Staff keeps the leadership agenda moving by managing strategic priorities, running key meetings and following through on decisions. Their work spans planning, coordination and problem-solving at the highest level of the business.
Typical responsibilities include setting and tracking strategic priorities with the CEO, running the leadership team's agenda and managing cross-functional projects that do not sit neatly with any one department. Many Chiefs of Staff also prepare materials for the board, investors and other key stakeholders, making sure the executive is well briefed.
A Chief of Staff often acts as the CEO's proxy, representing them in meetings, making decisions within an agreed remit and communicating messages across the business. They also own the operating rhythm: the cycle of leadership meetings, planning sessions, reporting and reviews that keeps the organisation aligned.
How Is a Chief of Staff Different From an Executive Assistant?
A Chief of Staff focuses on strategy, priorities and the leadership team, while an Executive Assistant focuses on managing the executive's time, communications and logistics. The two roles are complementary, and many senior leaders have both.
An EA ensures the CEO is in the right place, with the right information, at the right time. A Chief of Staff ensures the CEO's time and the leadership team's effort are directed at the right priorities. In practice they work closely together, with the EA often coordinating the schedule that supports the Chief of Staff's operating rhythm.
How Is a Chief of Staff Different From a COO?
A COO runs the operational functions of the business and usually has significant line management responsibility, while a Chief of Staff typically works across the leadership team without owning a large function. The COO is accountable for delivery in specific areas, whereas the Chief of Staff is accountable for alignment and follow-through across the whole agenda.
Some Chiefs of Staff later move into COO or other senior operating roles, which is one reason the position attracts ambitious, commercially minded candidates.
When Is It Time to Hire a Chief of Staff?
It is usually time to hire a Chief of Staff when the CEO or founder is stretched across too many priorities and important work is slipping through the gaps. The need often becomes clear during periods of rapid growth or change.
Common signs include a founder who is personally involved in too many decisions, a growing list of strategic initiatives with no clear owner, and leadership meetings that produce discussion but little follow-through. Misalignment within the leadership team, where functions pull in different directions, is another strong indicator.
Businesses preparing for investment, an acquisition or international expansion also benefit from a Chief of Staff. These periods demand intense coordination, careful stakeholder management and a high standard of board and investor preparation.
What Should You Look For in a Chief of Staff?
The best Chiefs of Staff combine excellent judgement, absolute discretion, commercial and analytical skill and the ability to influence without formal authority. They need to be trusted by the CEO and respected by the leadership team.
Judgement matters because a Chief of Staff constantly decides what needs the CEO's attention and what can be resolved elsewhere. Discretion is essential, as they will have access to sensitive information on people, finances and strategy.
Commercial and analytical skill allows them to understand the numbers, assess options and contribute meaningfully to decisions. Influence without authority is perhaps the defining capability: a Chief of Staff must move projects forward through relationships and credibility, often with colleagues more senior than themselves.
How Should You Structure the Chief of Staff Role?
Structure the role with a clear remit, a direct reporting line to the CEO or senior executive, and agreed measures of success. Without these, the position can drift into general administration or become an undefined strategic role that frustrates everyone.
A clear remit sets out which priorities, projects and meetings the Chief of Staff owns, and where their authority begins and ends. The leadership team should understand this from the start, so that the role is seen as supporting them rather than bypassing them.
Success measures might include progress on agreed strategic initiatives, the effectiveness of the operating rhythm or the quality of board and investor preparation. Reviewing these regularly helps the role evolve as the business grows.
How Do You Hire a Chief of Staff Successfully?
Hiring a Chief of Staff successfully depends on a precise brief, a targeted search and close attention to cultural fit with the CEO. Because the working relationship is so close, chemistry and working style matter as much as experience.
Candidates come from a range of backgrounds, including consulting, finance, operations, senior executive support and internal strategy roles. A well-targeted search will usually surface stronger candidates than advertising alone, as many suitable people are not actively looking.
The interview process should test judgement and problem-solving through realistic scenarios, and give the CEO meaningful time with shortlisted candidates. Eden Recruitment Group supports employers in London and the US with Chief of Staff appointments, with an emphasis on culture-first matching and long-term fit.
Does the Chief of Staff Role Differ Between London and the US?
The core of the Chief of Staff role is broadly similar in London and the US, although titles, scope and seniority vary between organisations in both markets. In each case, the role is shaped far more by the needs of the CEO than by geography.
In both cities, the title is common in growth businesses, private equity and investment firms, financial services, professional services and founder-led companies. Employers hiring across both markets should define the role consistently, so that candidates in each location understand the level and remit being offered.
Final Thoughts
A Chief of Staff can transform how effectively a CEO and leadership team operate, turning strategy into coordinated action. The role works best when it is introduced at the right moment, structured with a clear remit and filled by someone with the judgement and influence to make it succeed.
For growing businesses in London and the US, a well-chosen Chief of Staff often becomes one of the most valuable appointments a leader can make.
