Still relatively uncommon in Brazil, the role of Chief of Staff (CoS)—once limited to governments and military institutions—is increasingly gaining prominence across companies of all sizes and industries.
According to recent data from the Harvard Business Review, in the U.S., 78% of S&P 500 companies already have a CoS, while globally, 72% of companies with revenue above US$1 billion have adopted the role, according to McKinsey. In Brazil, 70% of unicorns are already seeking or have a CoS, according to recent LinkedIn data.
The CoS acts as a bridge between corporate strategy and execution, helping CEOs reduce operational workload, speed up decision-making, and align teams. In startups, they organize rapid growth; in large corporations, they promote efficiency and agile decision-making.
With a background in business, law, or engineering, and skills in communication, data analysis, and crisis management, the CoS can advance to positions such as COO.
To perform well in the role, continuous education is necessary: degrees in business, law, or engineering, an MBA, plus skills in data analysis, strategic communication, crisis management, and leadership of multidisciplinary teams.
The CSA (Chief of Staff Association) offers certifications for aspiring or current CoS, as well as periodic courses, events, and international networking opportunities, reinforcing the professional’s role as a strategic ally within companies.
