As your business grows, the need for support at the top becomes critical. But when you’re choosing between a Chief of Staff and an Executive Assistant, understanding their unique roles is essential.

Key Differences Between a CoS and an EA

Aspect Chief of Staff Executive Assistant
Scope of Work Strategic initiatives, project leadership, team alignment. Administrative tasks, scheduling, meeting support.
Decision-Making Makes high-level decisions and provides insights. Supports decision-making but doesn’t directly decide.
Focus Big-picture strategy and execution. Day-to-day administrative efficiency.
Business Impact Drives growth, efficiency, and alignment. Keeps operations running smoothly.

Who Do You Need?

  • Choose a Chief of Staff if you’re scaling rapidly, need operational alignment, or want a partner to take ownership of strategic initiatives.
  • Choose an Executive Assistant if you need help managing your calendar, scheduling meetings, or organizing your workload.

For many businesses, the choice isn’t either/or—it’s both. An EA manages the details, while a CoS drives strategy and execution.
