The 4 types of Chiefs of Staff
Behind the scenes in the business world, the role of Chief of Staff (CoS) is shrouded in mystery, surrounded by a variety of multi-talented personalities. Today, we reveal the four personas behind this strategic and versatile role, at the crossroads of expertise and leadership.
The "Parliamentarian"
Like a skilled diplomat, this first profile focuses on external affairs and corporate issues. Often graduating from prestigious institutions such as Sciences Po, they have worked their way up through the ranks of government ministries before ending up working for the big boss. They could sometimes be confused with a chief of staff. Their expertise in politics and mastery of external relations make them a valuable asset to the leader.
The "CAC 40"
This second profile comes from prestigious business schools such as HEC Paris. As an executive assistant to a senior manager, they spend much of their time coordinating meetings. This role often proves to be a springboard to positions of greater responsibility, with a more specific and operational scope. Considered a "high potential" within the company, they are destined to take on a future management position.
The "Scale-up"
Young and full of entrepreneurial potential, the third profile is firmly focused on new technologies. With a forward-looking vision, they are often driven by a desire to join the world of venture capital (or have already done so), become a COO, or even start their own business. This bold profile is a catalyst for change and innovation within the organization.
The "Right Hand Man"
The fourth profile is rarer and often more experienced. Aspiring to reach the position of CEO, they generally come from a large consulting firm, have specific expertise, or come from a large group. Seeking to become the next CEO, they position themselves as the CEO's right-hand man. Like a semi-dolphin (🐬), they seek to give the company new momentum and are ready to take on the most ambitious challenges.
