May 5, 2026The Long Game in Agent Companies

Agent companies are marathons you sprint through. Frameworks commoditize, monetization pins to infrastructure, and proximity to real builders is the moat.

May 4, 2026Agents in Production: GTM Mesh and the Death of the ERP

The same mesh-of-agents pattern that closes the gap between ad click and revenue is the one that retires the ERP dashboard. Two examples, one architecture.

May 3, 2026From Agent to Platform: Why the GTM Is Services-Shaped

There is no winner-take-all platform in agents. The GTM is services-shaped, the harness is commoditized, and coding-agent companies have a narrow window to pivot before the floor falls out.

May 2, 2026Why Homegrown Agent Platforms Break

Every large company is quietly building an internal agent factory. The stack looks the same everywhere, and most of these systems will be in disrepair within a year.

May 1, 2026The Agent Harness Problem

Enterprise agents need layered interfaces, real software skills, and flexible platforms. The harness around the model matters more than the model.

Apr 30, 2026The Atomic Agent Mesh: Architecture, Build-vs-Buy, and the Review Layer

Enterprise AI will not be one mega-agent. It will be a mesh of atomic, auditable units, and the companies that nail review and context will own the next infrastructure layer.

Apr 29, 2026Context Engineering Is the Hard Problem

Models keep getting better, but agents without deep codebase and organizational context are just expensive autocomplete. Context engineering is the bottleneck nobody has productized.

Apr 28, 2026Workflows, Not Roles: Why Scoped Agents Win

Role-based agents promise to replace a job and require infinite context engineering to deliver. Workflow-based agents start small, ship in a week, and compound.

Apr 27, 2026Knowledge Work Automation Is Software Engineering. Period.

Enterprises treating AI agents as a procurement decision will fail. Agents are software, every obvious idea commoditizes in weeks, and the bottleneck has moved from writing code to reviewing it.

Apr 26, 2026The Operationalization Gap: Where AI Demos Go to Die

The gap between an AI demo and an AI deployment is called software engineering. Most organizations are not equipped to close it, and that is where all the value lives.
