David sells AI chatbots to dental and medical practices. $800 for setup, $200/month for maintenance. Fifteen clients. $4,600-$5,400/month. Fifteen hours of work per week. Not hypothetical — this is a documented income report from a real person running this business solo.
The Business Model
Setup fee: $800 per practice. Covers building the chatbot, training it on the practice's FAQs, services, insurance policies, and scheduling system. Takes David 3-4 hours per setup.
Monthly retainer: $200 per practice. Covers ongoing maintenance, answer updates, performance monitoring, and minor tweaks. Takes about 30 minutes per client per month.
The math:
- 15 clients × $200/month = $3,000 recurring
- 2-3 new setups per month × $800 = $1,600-2,400
- Total: $4,600-5,400/month
- Hours worked: 15/week
- Effective rate: ~$85/hour
Why Dental Practices Pay For This
A typical dental practice gets 30-60 calls per day. Half are routine: "Do you accept Delta Dental?" "Saturday hours?" "How much for a cleaning?" Every missed call is a potential patient worth $500-2,000/year walking away.
A receptionist costs $3,000-4,000/month. David's chatbot handles 60-70% of those inquiries for $200/month. Practice managers do not need a sales pitch to see the value here.
What the chatbot handles:
- Insurance acceptance questions
- Appointment scheduling and rescheduling
- Service pricing and descriptions
- Office hours and location
- New patient intake forms
- Emergency triage (routes urgent cases to staff)

How He Got His First 15 Clients
Months 1-2: Cold-called 50 dental practices. Offered free 2-week trial. 5 said yes. 4 converted to paying clients.
Months 3-4: Asked happy clients for referrals. Dental communities are tight — word spread. Got 6 more clients through referrals.
Months 5-6: Created a simple one-page website showing case studies. Ran $200/month in Google Ads targeting "dental practice chatbot." Got 5 more clients.
Current acquisition cost: ~$100 per client through referrals and ads. Lifetime value at 12-month average retention: $2,400+. Payback period: less than 1 month.
Where It Goes From Here
David's target is 50 clients ($10,000+/month recurring) by end of 2026. At that scale, he hires a part-time assistant ($1,500/month) for setup and maintenance while he focuses on sales and expands into other medical specialties — dermatology, physical therapy, optometry.
With 100+ clients and an assistant, this is a $25,000+/month business at 70% margins. Built on a service he learned in 2 weeks, running on less than $100/month in tools.

The Core of It
