Inbounds.com scales high-ticket call campaigns with Retell AI voice agents

The problem

Inbounds.com's call center model was difficult to scale due to logistical complexity, high capital requirements, and lengthy agent training cycles of about 2.5 weeks. Out-of-hours outreach was hard to staff, data handoffs between systems were chronically inefficient, and early AI voice tools lacked the flexibility and response speed needed for high-ticket campaigns.

First attempt

Early AI voice solutions Inbounds.com tested lacked the flexibility to integrate with their lead gen pipeline and had unacceptable response times that disrupted natural conversation flow.
