Auralis Labs — Multi-Tenant Voice AI Platform
Production-grade B2B multi-tenant conversational AI voice platform that handles inbound calls, books appointments in real time, and ships a white-label dashboard — all fully isolated per tenant business.
Tech Stack
Overview
Built a production-grade multi-tenant SaaS voice AI platform for Maximus Virgili (Auralis Labs). Each business that onboards gets their own dedicated phone number, a fully configurable AI voice agent with a custom personality, real-time Google Calendar integration for appointment booking, and a white-label dashboard. The platform is architected from day one for B2B scale — adding a new industry vertical (dental, med spa, salon) is a configuration change, not a code change.
