The Davos for chiefs of staff
The Global Chief of Staff Dialogue is the world’s largest in-person conference for chiefs of staff, held over two days with keynote presentations, breakout sessions and a gala dinner. It gathers hundreds of chiefs of staff from dozens of countries, representing multiple industries and companies. Like Davos for global leaders, the Dialogue offers chiefs of staff a forum to define best practices and collectively scan the horizon for emerging opportunities and threats.By framing each Dialogue as “COS + Year”, we both timestamp each iteration and place our event among the great conferences of the world.
