Headline
Converge — 70% reduction in call handling cost.
Appointment-based businesses — clinics, allied health, professional services, beauty and wellness — spend a disproportionate amount of staff time on routine inbound calls. Bookings, reschedules, cancellations, basic FAQs. The calls arrive outside business hours and queue during peaks. Reception capacity is consumed on work that should not need a human.

Challenge
Appointment-based businesses — clinics, allied health, professional services, beauty and wellness — spend a disproportionate amount of staff time on routine inbound calls. Bookings, reschedules, cancellations, basic FAQs. The calls arrive outside business hours and queue during peaks. Reception capacity is consumed on work that should not need a human.
Approach
Built Converge as a multi-tenant SaaS voice automation platform. Twilio Voice with Media Streams for real-time audio. OpenAI Whisper for STT, GPT-4o for conversation handling, ElevenLabs for natural TTS. Spring Boot 3 / PostgreSQL / Cloud Run for the production backend. Per-tenant isolation: separate Twilio sub-accounts, separate AI persona, separate appointment schedules.
Outcome
70% reduction in call handling costs versus human equivalent. $0.40 per call, against $2.70 to $7.68 for human handling. 90 day payback period. Live in production with healthcare and professional services clients. Multiple tenants today, the platform scaling without the engineering team scaling.
