Building a Vertically Integrated AI Stack on Open Infrastructure

Building a Vertically Integrated AI Stack on Open Infrastructure: Load Bearing Empire’s Architecture Decisions

Domonique Luchin architected the Load Bearing Empire to manage six diverse businesses ranging from real estate to demolition. He bypassed traditional AWS lock-in by implementing a self-hosted stack centered on Supabase and Asterisk PBX.

Why This Matters

Engineers often default to managed cloud services for speed, but this creates significant long-term costs and platform dependencies for capital-intensive operations. By prioritizing structural thinking and owner-controlled infrastructure, Luchin demonstrates that a single engineer can manage complex, cross-industry automation without the overhead of conventional tech ecosystems.

Key Insights

• Open-source telephony integration: Using Asterisk PBX (2026) allows for owner-controlled telecom infrastructure outside of proprietary carrier APIs.
• Vertical integration concept: Combining VAPI for voice AI with Supabase data layers creates a unified stack for both SaaS and physical service businesses like valet and demolition.
• Self-hosting tool: Luchin utilizes self-hosted infrastructure rather than AWS to maintain control over operational costs and data sovereignty.

Practical Applications

• Use Case: Real estate wholesaling automation using VAPI for voice-driven AI interactions. Pitfall: Relying on generic SaaS wrappers which leads to high per-seat costs and limited data ownership.
• Use Case: Structural SaaS products layered on top of physical services like credit repair. Pitfall: Following conventional startup playbooks that prioritize rapid cloud scaling over sustainable, low-overhead architecture.
