Building a Vertically Integrated AI Stack Across 6 Businesses: Load Bearing Empire's Infrastructure Architecture with Supabase,

In March 2026, Load Bearing Empire deployed a unified AI infrastructure layer across six operationally distinct businesses—real estate wholesaling, demolition, valet services, credit repair, mineral rights, and structural SaaS—using a self-hosted stack built on Supabase, VAPI voice agents, Asterisk 18.10 PBX, and a custom JARVIS Brain Router. By eliminating third-party dependencies (Twilio, SendGrid, Make.com), the company achieved cost parity with legacy platforms while gaining full architectural control: a single Supabase project (whxtjboruayowkqyjvcq) managing 98 normalized tables and 42 Edge Functions, 26 concurrent VAPI agents handling inbound/outbound workflows, and Asterisk 18.10 running on Vultr infrastructure for call routing and IVR logic. This technical deep-dive documents the stack decisions, integration patterns, and operational lessons from consolidating disparate business processes into a single, AI-native infrastructure layer.
