What Retell AI is
Retell AI is a voice-agent platform for building AI phone agents that handle inbound and outbound calls, priced usage-based at roughly $0.07-$0.31 per minute depending on the LLM and voice you pick. It ships a drag-and-drop agent builder, simulation testing, batch outbound calling, and HIPAA/SOC 2 Type II compliance. New accounts get $10 in free credits — enough to build and demo a client prototype before you pitch it.
Key features
- Drag-and-drop agent builder with real-time function calling (booking, payments, warm transfer)
- Simulation testing before launch plus continuous QA on past calls
- Batch outbound calling with conversion tracking
- Knowledge base with streaming RAG that auto-syncs from your website content
- SIP trunking, branded caller ID, and verified phone numbers
- HIPAA, SOC 2 Type II, and GDPR compliance
💰 Sell it as a service
The offer
Build and manage AI receptionists and missed-call recovery agents for local service businesses — med spas, HVAC, law firm intake — on Retell's infrastructure.
What to charge
$2,000-$3,500 setup + $300-$500/mo management. Your hard cost is roughly $0.10-$0.15/min, so a client doing 1,000 minutes a month costs you about $150 — the rest is margin.
How it gets delivered
Build the agent in the no-code builder, wire bookings into the client's calendar and CRM via webhook or Make/Zapier, run simulation tests, then forward or port the client's number. First build takes a weekend; repeat builds take a day.
This is one offer. AI Operator Academy is where operators build the full stack — packaging, pricing, fulfillment, and a peer group selling the same services. $999/yr.
