Scaling Client Intake with Vapi Voice AI Agents: A Consultant's Case Study

Consultant Christian Ulstrup of GSD at Work used Vapi voice AI agents to replace scheduled discovery calls with an asynchronous voice intake system for his AI Action Sessions workshops. Participants call a dedicated Vapi phone line at their convenience, and transcripts plus AI-generated summaries flow into Slack via Zapier and are logged in HubSpot. For one recent client, 20 participants across the globe contributed over 3 hours of discovery, and the session earned a 5 out of 5 rating.
