Tellia, the AI CRM that books, coordinates & reminds for you
Tellia connects an AI agent to your operation: it books appointments by phone and WhatsApp, organizes calendars and on-site/online visits, and reminds your team of every meeting. It all shows up on a web dashboard with real-time KPIs.
What Tellia does for your team
An AI agent that doesn't just talk: it books, coordinates, and notifies the right people at the right time.
24/7 call reception
A voice agent answers every call around the clock, books the appointment directly on the available rep's calendar, and confirms via WhatsApp.
On-site & technical visits
Coordinates sales, technical, or real-estate visits: proposes time slots based on the field team's real availability.
Automatic team reminders
Notifies each person ahead of their meeting or visit, and reschedules automatically when someone cancels.
Dashboard & KPIs
Web dashboard with booked appointments, show-up rate, calls handled, and per-rep load, in real time.
