May 6, 2026Follow No Goose Absolutely

Design partner programs prevent enterprise AI companies from building three products when they should have built one.

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 3, 2026The Human Is No Longer the Integration Layer

The ERP is not going away. The CRM is not going away. The landing page is not going away. But the human as the operating system between them is. The agent takes that job now.

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.

May 1, 2026Start With the Pain, Not the Platform

The temptation with agent projects is to start with the technology. That is how you end up with a demo that impresses nobody who actually has to use it.

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 30, 2026Background Agents Are the Underbuilt Layer

Coding copilots are crowded. Background agents — autonomous, scheduled, reviewable — are what enterprises actually need, and almost every product shipping today is a toy by their standards.

Apr 30, 2026Tech Context Is Tractable. Org Context Is Not

The hardest unsolved problem in agent infrastructure is not compute or sandboxing. It is context — and most of that context lives in people, not repos.

Apr 29, 2026The ERP Is Dead. The Agent Is Your Operating System Now

The ERP was supposed to solve the toggling-between-six-tools problem. It did not. The agent does — by becoming the operating layer on top of every system you already paid for.

Apr 29, 2026The Gap Is Infrastructure, Not Intelligence

The distance between an AI demo and an AI deployment is not a model gap or a harness gap. It is the absence of composable primitives for the boring parts of operationalization.

Apr 29, 2026The Primitives Are the Same Across Roles

Sandbox, tools, prompts, governance — the primitives are universal. Engineering agents and GTM agents share the same engine. Only the body changes.

Apr 28, 2026What the Build-vs-Buy Data Actually Shows

From Stripe to a five-person startup, the agent stack is mostly blue — built in-house. The harness is bought. The middle of the stack is built. The opportunity sits in turning blue dots green.

Apr 28, 2026Flexibility Is Not Optional for Agent Platforms

Multi-CLI, multi-model, multi-repo, self-hosted, and pluggable integrations are table stakes. No enterprise wants to be locked into one vendor's harness.

Apr 27, 2026Think Small to Win Big

The companies that try to skip to the grand AI vision will burn capital. The ones that start with one workflow per developer will compound their way into something much larger.

Apr 27, 2026The Forward-Deployed Model Is the Only One That Actually Works

Every agent needs to be personalized and context engineering is hands-on, so the vendor who embeds engineers inside the customer has a structural advantage. Self-serve ships shelfware.

Apr 27, 2026The Harness Matters as Much as the Model

Engineers report meaningfully different results from the same model run through different harnesses. The harness is not a thin wrapper — it is an opinionated layer that shapes agent behavior.

Apr 27, 2026The Mesh of Specialists Pattern

One mega-agent does not work. A fabric of small, single-purpose agents — each doing one thing with high confidence — coordinating through shared context does.

Apr 26, 2026Agent Build Versus Buy: Why Engineers Keep Building It Themselves

An engineer can ship a working agent harness in a week and a half. Code is cheap. So what does a paid agent platform offer that a week of engineering does not?

Apr 26, 2026The Agent Buyer Map: Who Builds, Who Buys

Companies with mature dev tooling build their own agent stack. Companies without it buy off the shelf. That buy cohort is the real addressable market.

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.

Apr 25, 2026Controllability Is Not Optional. Enterprise Teams Do Not Want Magic

Enterprise teams do not want magic agents. They want control over which submodules load, which tools run, and what the agent remembers — because they have been burned by black boxes before.

Apr 25, 2026The Coordination Crisis AI Tooling Created

When everyone can build, nobody knows what has already been built. Five teams independently spin up the same Slack bot, and the duplication goes undetected for months.

Apr 25, 2026Customization Is the Moat, Not Model Quality

Frontier labs want workflow quality to be a function of model quality, because that is what they sell. The contrarian bet is that customization beats probability.

Apr 24, 2026Internal AI Tools Have a Twelve-Month Shelf Life

Three weeks of work can match a dedicated AI vendor. Six months later, the same tooling feels like it was built in a different era — because in AI terms, it was.

Apr 24, 2026Triggered Workflows Generate Most of the Volume

Most enterprise agent value comes from background workflows, not from humans typing into a chat box. Machines do not sleep. Lean into triggered work or get out-shipped.

Apr 23, 2026Homegrown Platforms Decay

Internal agent platforms are built by ambitious individuals with other jobs. When those engineers move on, the platform becomes a liability.

Apr 23, 2026The Mesh, Not the Monolith

One mega-agent that handles everything is exhilarating to demo and chaotic in production. Enterprise wants a mesh of specialized agents with human pilots.

Apr 22, 2026The Convergent Agent Stack

Fifty companies building internal agent platforms have independently arrived at the same architecture. That convergence is the productization tell.

Apr 22, 2026What Workflow-First Looks Like in Practice

A customer success team, five fragmented systems, and a workflow agent that ships in a week. How small scoped wins compose into something that looks like a role.

Apr 21, 2026The Agent Infra Maturity Gradient

Mature engineering orgs reuse existing dev infra. Less mature orgs buy off the shelf. Scrappy teams hand-roll everything. The opportunity sits in the gap between them.

Apr 21, 2026The Unit of AI Consumption Is the Organization

Today every developer has a personal subscription. Tomorrow the organization has a shared agent fabric — pooled credits, role-based access, routed across models.

Apr 20, 2026The Submodule Problem Is the Whole Problem in Miniature

Submodules are a specific pain point, but they illustrate a universal truth. Enterprise codebases are not simple, and agents that cannot handle them cannot handle enterprise software.

Apr 19, 2026Start With Workflows, Not Roles

Role-based agents start with the hardest version of the problem. Workflow-first agents start small, ship in a week, and compound into something larger.

Apr 18, 2026The Mirror Problem

95% of enterprise AI projects fail not because the models are weak. They fail because the company cannot describe its own processes well enough for an agent to act.

Apr 17, 2026The Mega-Agent Fantasy Is Already Falling Apart

Enterprise AI is not one omniscient agent. The mega-agent fantasy collapses on contact with production, and the failure mode is always the same.

Apr 17, 2026The Procurement Trap

Enterprises that approach AI agents as a procurement decision keep discovering they actually have a software engineering problem. There is no vendor shortcut.

Apr 16, 2026The Demo Is Not the Deployment

A French CTO with twelve Claude Max seats can ship from his laptop and watch his product team file tickets and wait. That gap is the real problem.

Sep 9, 2025Beyond the Coast-to-Midwest AI Gap

Silicon Valley is building AI coding tools for Silicon Valley. The PE-owned manufacturer in Ohio with three tired developers is the underserved market that matters.
