The agentic stack — four layers
Not thirty boxes. One line of work: from a model you rent to plumbing you own.
Rented
Model
Pick one brain for the job. Hard reasoning · everyday work · cheap volume. Swap models. Don’t build your company on a single chat window.
Rented / product surface
Workspace
Where work happens. Code · multi-step projects · slides & prototypes. Still a product. Still someone else’s UI.
Your systems
Tools & data
Connect once, stop copy-paste. APIs · MCP-style connectors · the apps your team already lives in. This is where productivity shows up.
Owned · non-negotiable
Governance
Identity · audit · human gates · kill switches. Memory and CI/CD only matter if this layer holds. Regulators examine plumbing — not demos.
Intelligence is rented. Plumbing is owned.
