Calendar Coordinator Agent

Replaces a $60k Executive Assistant. Books across calendars, blocks focus time, kills double-booking.

The Problem

An SMB owner spends $60k/yr on an Executive Assistant whose biggest day-to-day pain is calendar Tetris — finding overlapping windows across 4 people, defending focus time, rescheduling when a client cancels. The work is 90% pattern matching across availability JSON.

The Outcome

New booking request hits the agent → it pulls 5 calendars (Google + Outlook), finds 3 mutual windows that respect each person's focus blocks and timezone, drafts a hold on all calendars, sends a Cal.com booking link with those 3 options to the requester. Confirms within 4 minutes.

Day in the Life

8:30am: scans the week, blocks 2x 90-min focus windows on the owner's calendar before clients can grab them

Throughout day: any new meeting request → checks 4-team availability via Cal.com event-types, returns 3 options that don't crash with focus blocks or PTO

5:00pm: emails owner the next-day agenda — meetings, prep needed, drive time between offsites, any back-to-back stacks that should be re-spaced
