The before: a database full of dormant patients
The clinic chain had thousands of past patients in Viber and no time to call them. People who came once and never rebooked were not unhappy, they just drifted, and nobody followed up. That dormant base was the clinic's biggest untapped asset and its biggest blind spot at the same time.
Weeks 1-2: a reactivation pilot
We put a MyChatBot Viber agent on two locations, with services and pricing in a Product Spreadsheet and recall logic in Business Domain docs. The agent reached out to lapsed patients with a warm, personal message, answered their questions, and booked a return visit straight into Google Calendar, all in natural language, no call center.
Weeks 3-4: rollout to 12 locations
With reactivation working, we cloned the agent across all 12 clinics, each with its own calendar and pricing but one shared CRM. Every reawakened patient became a tracked lead with a chat link, so head office could see exactly which locations were refilling their schedules.
Where humans stepped in
Medical questions never get improvised. Hand-off Control routed anything clinical or sensitive to staff via Flight Control in Telegram, with silent hand-off so the patient felt one caring conversation. The agent handled scheduling and recall; the clinic handled care.
The result: 38% of lapsed customers recovered
In four weeks the chain recovered 38% of its lapsed Viber customers, appointments that would never have happened without a follow-up nobody had time to send. The dormant database became the cheapest growth channel they had. The lesson: most "lost" customers are simply waiting for a reason to come back.
