Building a Multi-Tenant AI Stack for 6 Businesses: Load Bearing Empire's VAPI + Asterisk + Supabase Architecture

Building a vertically integrated business empire on bootstrapped capital means every infrastructure decision has to earn its keep. When Domonique Luchin consolidated Load Bearing Capital, Load Bearing Demo, Quiet Hours Valet, Luchin Credit Repair, Petroleum Noir, and StructCalc AI under a unified AI stack, the requirements were brutal: eliminate SaaS sprawl (Twilio, SendGrid, Make.com), route intelligent voice agents across six distinct business models simultaneously, and maintain 98-table database integrity across heterogeneous workflows—all on self-hosted infrastructure. This article documents how we deployed the LB Empire OS: a JARVIS-pattern Brain Router orchestrating 26 VAPI agents, Asterisk 18.10 PBX on Vultr, and Supabase (project whxtjboruayowkqyjvcq) with 42 Edge Functions handling everything from real estate lead qualification to valet task distribution, built to scale from a phone into a full operational infrastructure without the cloud bill.
