4 stages of bringing AI into a company — and which one yours is stuck at

Boris Cherny, creator of Claude Code at Anthropic, described a ladder of AI adoption: from "locked down" to AI-native. We've climbed most of it the hard way ourselves. I'll lay it out as a route — with marks at the spots where almost everyone stumbles.

"We've brought in AI" means different things at different companies: one engineer's productivity has multiplied, while the rest of the team hasn't rebuilt its processes yet. Boris Cherny offers a scale that brings order to this mess. Below is a retelling in our own words, with examples from how we at MILAGPT are building a network of AI employees.

Stage 0: AI "exists", but under lock and key

A familiar picture: the company bought access to a chatbot, wrapped it in approvals, routed it through a corporate gateway and cut it back to old models. Agents: zero. The result lives in a chat window and dies there.

The diagnosis is precise: the bottleneck here isn't technology, it's process. The company counts the cost of tokens instead of the cost of the result, and at the table where decisions are made there's no one who has actually worked with agents. The way out isn't technical but organisational: come to an agreement with those who pay, and tear down the blockers.

Stage 1: one engineer, one agent

The first real step: a person gets an agent as a partner. An edit that used to take half a day gets done between meetings. But the work is synchronous — you sit and proofread every line, because the agent doesn't check itself.

What moves you up isn't a smarter model but a self-verification loop you trust.

Tests, builds, a linter, a run in a real environment — so that the agent checks itself before you see the result. Until this loop exists, adding more agents is pointless: you'll just multiply the amount of proofreading.

Stage 2: an orchestrator of ten agents

Here one engineer conducts 5–10 agents, each with its own isolated branch so they don't elbow each other. Automatic code and security review are on by default. You look at the final diffs, not the process. A backlog of weeks fits into half a day.

This is exactly how we live at MILAGPT: a panel of several analyst agents fans out over a task, synthesises the conclusions — and a human reads the result, not thirty intermediate screens.

Stage 3: autonomy under supervision

The turning point. The agent no longer waits for a task — it watches its sources itself (channels, mail, data) and opens work itself. The question "did you read the code?" gives way to "what context was the model missing, and how do we give it next time?".

That's how our AI employees work: morning scheduled jobs check the systems on their own and flag problems, and the AI employee of a travel company reads the conversations with clients on its own and brings the owner a "pulse" in the morning: how many people are waiting for a reply, who is going cold. Nobody gave it these tasks — it found them.

The trap of this stage, one we stepped into too: scaling up agents before the self-verification loop has earned trust. You get confident reports about things the agent never double-checked. One rule cures it: the agent must prove the result with a run, not a story.

Stage 4: AI-native

The loop is closed: most agents are launched by AI itself; the human sets the intent and steps in where something went wrong. A migration that used to take a quarter turns into a workflow you just launch and check now and then. Only a handful have got here — but the whole ladder is already visible.

How to tell whether AI is really paying off

The framework's best idea is about the metric. Don't count tokens. Count the manual equivalent:

?Would your team have done this work by hand — and how many hours and how much money would it have cost?

The half-day edit, the weeks-long backlog, the quarter-long migration — those are the units of measurement. And the reverse filter: "would an engineer have done this at all?" If not, you're automating rubbish.

Which stage are you starting from

If you personally proofread every agent reply, you're at stage 1, and the next step isn't "more agents" but a self-verification loop. If the agents are working but you're the one carrying tasks to them, that's stage 2 — time to hand them the sources of context.

You can spend a year climbing this ladder, or do it faster with someone who has already climbed it. Our AI employees are a ready-made stage 3: an agent that finds work itself, checks itself and brings a result, not a process.

Take an AI employee for a test drive and look at your company from the next stage up.
