I build agentic systems that outlive the demo.
Mark Rizzn Hopkins is a Dallas operator who designs multi-agent systems and ships them as products through Decision Science Corp, SanctumOS, and Reps.
If you need a company that ships applied data science and AI you own, that's Decision Science Corp. If you want the agent stack itself — Tasks, CRM, Broca, SanctumBox — that's SanctumOS. If you need operators paid for real-world capture, that's Reps. This page is the origin story and the door, not the product catalog. Quasar, the old agent habitat, is offline as of October 2026 while Sanctum reboots it.
