Spot on about medical, Muhammad, but HIPAA and legacy EHR integrations can create high technical friction. Home services like HVAC, commercial lending, and property management are incredible alternatives with massive ROI. Whether it is capturing an after-hours $5,000 AC repair, warm-transferring qualified lending leads to brokers, or triaging 2 AM pipe bursts for property managers, speed to lead is everything. The real key to charging $2,000+ setup fees is selling the live calendar query and CRM sync using tools like n8n to GoHighLevel or ServiceTitan, rather than just the voice prompt itself.
