The Challenge & Problem Space

The client operates a high-ticket international consulting practice with 25 senior partners across London, New York, Singapore, and Dubai. Their manual appointment booking and standard Calendly links were causing severe operational friction:

  • Link Fatigue & Abandonment: Over 43% of prospective VIP clients dropped off when sent generic self-service calendar links via email.
  • Timezone Disasters: Frequent confusion between BST, EST, SGT, and GST leading to missed pitch calls and lost high-value retainers.
  • Last-Minute Rescheduling Overhead: Executive assistants spent 15+ hours weekly manually emailing back-and-forth to reschedule conflicting sessions.
  • No-Show Costs: Standard email reminders ended up in spam folders, resulting in a 28% no-show rate on first-time discovery calls.

The Solution & Technical Architecture

Aximo Labs engineered a multi-channel conversational booking agent that converses like a human executive assistant on WhatsApp, Website Chat, and Email, interfacing directly with Google Calendar API and Calendly webhook listeners.
