Chief of Staff: Salary and Responsibilities in 2026

In French tech scale-ups, the Chief of Staff has become one of the most strategic hires of the growth phase. Not an assistant, not a junior COO: the Chief of Staff is the CEO's operational right hand, the person who turns leadership decisions into concrete execution. They unblock cross-functional issues, drive strategic projects, and free up the leader's bandwidth so they can focus on what matters most.

It's a rare, highly sought-after role, and one that's often misunderstood. This guide clarifies what the job really covers in 2026.

Job description updated on 07/06/2026.

Key takeaways

• The Chief of Staff is the CEO's (or another executive committee member's) operational right hand: they drive strategic projects, streamline the flow of information, and structure decision-making processes.
• It's a cross-functional role, with no fixed scope and no team of their own to manage: the CoS adapts to whatever challenges and blind spots leadership faces at a given moment.
• In 2026, a Chief of Staff's salary in France ranges between €65,000 and €120,000 gross/year, with packages exceeding €100,000 for senior profiles at large Paris-based scale-ups.
• The typical career path combines a top-tier school (business or engineering) with experience at a strategy consulting firm or a startup.
• Natural career paths: COO, Operations Manager, and often entrepreneurship afterward.

Why is this role growing so fast in tech scale-ups?

The Chief of Staff isn't a new role, but it has seen remarkable growth in the French tech ecosystem since 2020. The reason is simple: as a startup moves through growth stages (Series A, B, C), the CEO can no longer steer everything alone. Issues multiply, teams grow, and decisions become more complex. The Chief of Staff becomes the central node that keeps strategy and execution aligned.

Most startups that hire a Chief of Staff do so once they've reached a certain size and are anticipating strong future growth. These are companies that have already found their Product Market Fit and are on the verge of becoming a scale-up. It's also one of the most competitive roles on the market: openings are rare and highly sought after by profiles coming from consulting firms.

Core responsibilities of a Chief of Staff

Responsibilities vary depending on company size and the priorities of the moment, but the core of the role revolves around five areas:

• Driving strategic projects: leading cross-functional initiatives (reorganisation, digital transformation, tool rollouts, international expansion), tracking milestones and reporting to leadership
• Optimising the CEO's time: preparing leadership committee meetings, briefings, summary notes, tracking decisions and following up with stakeholders
• Monitoring overall performance: driving and analysing the company's key KPIs, spotting early warning signs, formulating recommendations
• Cross-functional coordination: acting as the interface between teams (Sales, Marketing, Ops, Product, Finance, HR) to ensure smooth information flow and consistent priorities
• Supporting transformation phases: rapid growth, reorganisation, fundraising, entry into new markets — the CoS ensures operational continuity during turbulent periods

In some scale-ups, the Chief of Staff also handles HR topics (defining hiring needs, onboarding key hires) or finance topics (P&L tracking, preparing board meetings).

Key skills of a Chief of Staff

Strategic and analytical skills

The analytical dimension is central. The Chief of Staff must be able to step back from complex issues, quickly synthesise heterogeneous information, and formulate actionable recommendations. A solid understanding of finance (P&L, budgets, KPIs) is expected.

Operational skills

Beyond strategy, the CoS needs to be hands-on. They can't just analyse: they need to get into the details, unblock situations, and execute. This is often what distinguishes an effective Chief of Staff from an overly theoretical profile coming from consulting.

Soft skills

• Leadership through influence without hierarchical authority (convincing without imposing)
• Excellent interpersonal skills and the ability to bring together teams with diverging interests
• Fluent written and verbal communication, with a strong ability to synthesise
• Adaptability and prioritisation in a high-velocity environment
• Discretion and confidentiality (the CoS is exposed to the company's most sensitive information)

Tools and work environment

The Chief of Staff works in close proximity to leadership, which means an intense environment highly exposed to strategic decisions. Tools vary depending on company maturity:

• Project management: Notion, Asana, Monday, Linear (for tracking cross-functional initiatives)
• Reporting and data: Google Sheets, Metabase, Tableau, Looker (for tracking KPIs)
• Communication: Slack, Google Workspace, Zoom (daily coordination with all teams)
• Finance: financial modelling tools (advanced Excel, Pigment, Causal) for P&L tracking and board prep
• Recruiting: ATS (Lever, Greenhouse, Workable) when the CoS handles HR topics

Partial remote work is common, but regular in-person presence alongside the CEO is often expected, especially during intense transformation phases.

Training and background to become a Chief of Staff

In France, Chief of Staff profiles almost all hold a Master's degree from a top business or engineering school. The main schools these profiles come from: top-tier business schools (HEC, ESCP, ESSEC, EM Lyon, EDHEC), top-tier engineering schools (Polytechnique, CentraleSupélec, Mines Paris Tech), and Sciences Po Paris with a Master's in Finance and Strategy.

Experience at a strategy consulting firm (McKinsey, BCG, Bain, Roland Berger) is the most valued background before a first CoS role. It provides analytical rigour, complex project management, and the ability to structure high-level recommendations. Profiles from investment banking or with prior startup experience (Strategy Associate, strategic project lead, Finance Manager) are also highly sought after.

There is no specific "Chief of Staff" training in France. It's a role learned through experience, not through a diploma.

Chief of Staff salary in 2026

Compensation depends heavily on company size, funding stage, and the profile's seniority level.

Junior / First CoS role (3-5 years of experience, ex-consulting)

• Annual gross salary: €60,000 to €75,000
• Often paired with BSPCE (stock options) in growing startups

Confirmed (5-7 years of experience, Series B/C scale-up)

• Annual gross salary: €75,000 to €100,000
• Package that can reach €110,000 with variable and equity

Senior (7+ years, mature scale-up or unicorn)

• Annual gross salary: €100,000 to €120,000 and beyond
• In Paris, the average salary is €83,000 gross/year, with a range from €61,100 (25th percentile) to €117,500 (75th percentile), according to Glassdoor France (June 2026)

Île-de-France concentrates the highest packages. In other regions, compensation is generally 10 to 15% lower.

Possible career progression

• COO (Chief Operating Officer): the most common progression, taking on operational leadership and managing a team
• Operations Manager / Head of Ops: a narrower scope, with direct responsibility over the operations of a specific area
• Strategy & Transformation Director: especially in large groups or post-IPO scale-ups
• Entrepreneurship: the 360° view gained alongside the CEO is a decisive advantage for founding or co-founding a startup

FAQ about the Chief of Staff role

What is the difference between a Chief of Staff and a COO?

The COO (Chief Operating Officer) runs the company's operations: they oversee teams, manage a defined scope, and hold direct hierarchical authority. The Chief of Staff is cross-functional and has no fixed scope: they have no team of their own but work across all of leadership's strategic issues. In scale-ups, the CoS role is often a stepping stone before becoming COO: they learn how the whole company operates, then take on an operational area. To learn more about this role, see our COO job profile.

Does a Chief of Staff need consulting experience?

It's not mandatory, but it's the most valued background on the market. Consulting experience brings analytical rigour, complex project management, and the ability to formulate high-level recommendations. Profiles from investment banking, a startup, or a corporate finance background can also access the role, provided they demonstrate strong execution ability and knowledge of the tech environment.

What is the difference between a Chief of Staff and an Executive Assistant?

The Executive Assistant manages the leader's calendar, travel, and day-to-day logistics. The Chief of Staff works on strategic issues: transformation projects, KPI tracking, coordination of leadership teams. The two roles are complementary but don't address the same level of responsibility or the same profiles.

At what point should a startup hire a Chief of Staff?

Generally once it reaches 50 to 100 employees, when the CEO can no longer track all strategic and operational issues alone. It's also a strong signal to teams and investors: the company is professionalising and equipping itself with the resources to reach the next stage. Hiring too early can result in an underused and frustrated Chief of Staff.

Does a Chief of Staff manage teams?

Generally not, at least not directly. The CoS exercises influence through coordination, persuasion, and the legitimacy granted by their proximity to leadership. In some scale-ups, they may have a few direct reports, but that's not the norm. The move toward a management role usually happens once the CoS takes on an operational area.

Can you become a Chief of Staff without a strategy consulting background?

Yes, notably through startup paths (Strategy Associate, strategic project lead) or finance paths (FP&A Manager, Finance Controller). What matters is the ability to manage complex topics in parallel, synthesise quickly, persuade without hierarchical authority, and thrive in a high-velocity environment.

Is the Chief of Staff role a good springboard to entrepreneurship?

Yes, it's one of the best. The CoS gains a 360° view of the company: strategy, finance, operations, product, HR, investor relations. They see how decisions are made, how crises are handled, how an organisation scales. This overall exposure is a decisive advantage for founding or co-founding a startup.

What is the difference between a Chief of Staff and a Business Developer?

Both profiles operate close to leadership, but their roles are very different. The Business Developer is outward-facing: prospecting, new markets, partnerships, closing. The Chief of Staff is inward-facing: structuring, coordination, strategic steering. In some early-stage startups, the same person may temporarily cover both roles, but as the company grows, the two positions specialise and become distinct.
