Building a Vertically Integrated AI Stack on Supabase and Asterisk: How Load Bearing Empire Unified 6 Businesses

OPENING PARAGRAPH:

When you're running multiple service lines—real estate wholesaling, demolition, valet, credit repair, mineral rights, and SaaS—across different tech stacks, you hemorrhage money on integrations. We eliminated Twilio, SendGrid, and Make.com entirely, replacing them with a single Supabase instance (project ID: whxtjboruayowkqyjvcq), 26 VAPI agents, and Asterisk 18.10 PBX hosted on Vultr. This article breaks down the technical architecture we deployed on March 17, 2026: how we built a JARVIS Brain Router to orchestrate inbound calls across businesses, structured 98 relational tables for cross-domain data (real estate transactions, demolition scheduling, valet routing, credit scores, mineral lease tracking, and SaaS usage), connected 42 Edge Functions for real-time business logic, and eliminated vendor lock-in at every layer. If you're running a portfolio of AI-first businesses and want to ship faster while cutting AWS bills by 60%, this is the stack that made it possible.
