Comparison
Chief of Staff vs Mavy
Mavy positions itself as your "Personal AI Executive Assistant" — broadly available, conversational, useful for many kinds of users. Chief of Staff makes the opposite bet: build for one specific person rather than for everyone.
The fundamental difference
Mavy is for everyone. Chief of Staff is for one specific person. "For everyone" means the interface optimizes for the average user, not the highest-volume one. Voice models, contact intelligence, and goal alignment require dense communication signal to learn — a product designed for a 15-emails-a-day user cannot retrain its UI for the 150-emails-a-day user. Chief of Staff is built explicitly for the funded startup CEO. Below that volume, the product tells you it's not for you during onboarding.
