Building a Vertically Integrated AI Stack: How Load Bearing Empire Unified 6 Businesses on Supabase, VAPI, and Self-Hosted Aster

When you're running real estate wholesaling, demolition, valet services, credit repair, mineral rights, and SaaS simultaneously—each with different operational requirements—your infrastructure either scales elegantly or collapses under its own weight. Load Bearing Empire chose the former: a self-hosted, open-source foundation built on Supabase, VAPI agent orchestration, Asterisk 18.10 PBX, and custom routing logic that eliminated vendor lock-in with Twilio and SendGrid. This article breaks down how one Black founder architected a unified AI nervous system across 6 distinct business units using 26 VAPI agents, 98 database tables, 42 Edge Functions, and a JARVIS-style Brain Router deployed on Vultr—all running on infrastructure you can actually own and modify.
