The starting point
The clinic was spending ~₺850K/mo on ads. WhatsApp drew 80+ daily messages — but operators averaged 4–6 hours to reply. In that gap, prospects either moved to a competitor or stopped messaging.
Consultation bookings were strong; procedure conversion was stuck at 18%. No-show rate sat at 32%. Management was reverse-engineering “which campaign actually produced a procedure” by hand at month-end.
The intervention
1. WhatsApp AI agent — instant first touch
In 14 days a Wasender + OpenAI bespoke WhatsApp agent went live. It:
- Quoted approximate price bands (not specific quotes — sensible ranges)
- Proposed appointments against the doctor’s calendar
- Pushed budget-and-intent-qualified leads into the CRM
2. Voice agent — no-show prevention
A Retell-based voice agent calls 48 hours and 2 hours before the appointment. If cancellation comes in, it instantly proposes an alternative. No-show went from 32% to 14% within eight weeks.
3. Sales AI follow-up sequences
For “I’ll think about it” walk-aways, a 14-day intelligent follow-up sequence:
- Anonymous post-procedure patient experience videos
- Financing options
- “Want to ask a question?” warm touch
- Limited-time consult-only offer
Outcome
After six months:
- Consultation → procedure: 18% → 41%
- Cost per procedure (ad-attributed): −47%
- Monthly procedure volume: 2.3× (the constraint became the doctor’s calendar, not demand)
- Referral volume: +34% (driven by the automated post-op chain)
“Aydın’s team didn’t sell us a bot. They diagnosed a years-old funnel leak in our procedure stage and closed it with AI. Now my growth problem is how to expand the doctor’s calendar.”
