What is a Chief of Staff?

Helping leaders double their available mental bandwidth—that is the mission of a Chief of Staff.

A CoS must be operational as quickly as possible after taking up the position. To prepare for this adventure, you will put the best tools into practice during simulations based on real-life cases.

Educational expertise

For each topic in our program, a CoS will take part. Our content will also be delivered by our passionate instructors. To help you fully understand the day-to-day reality of the profession, you will have the opportunity to meet CoS with diverse backgrounds who will share their experiences and methods.

The origins of BeCoS

Welcome to a space dedicated to your well-being.

BeCoS was born from a simple observation: the Chief of Staff role is growing rapidly, but it is still not well understood, not very structured, and rarely taught. Yet this role is becoming essential for leaders who need to make decisions faster, communicate better, and run increasingly complex organizations. Created by Yahya Fallah, co-founder of Seven, and Grégoire Kopp, former Chief of Staff at OVHcloud, BeCoS was designed as a hands-on program: an intensive training course, built with Chiefs of Staff, to learn the job alongside those who actually do it.

Our B2C training programs offer an exceptional learning experience. Whether you want to develop new skills, deepen your knowledge, or improve in a specific field, our workshops are designed to meet your needs.
