◉ Status — Outline, full write-up in progress

This page is a structural placeholder. The full operator-substrate write-up — describing the architecture of the Atteste Substrate, the day-to-day operating loop, what the AI handles vs. what the human signs, and the lessons we've learned running it — is in active drafting and will publish here.

The thesis in one sentence

A SaaS company can be operated end-to-end by a single human plus an AI agent if the AI has access to a custom-fit Substrate that captures everything the business knows.

What the substrate captures

The day-to-day operating loop

Every morning, Claude reads the overnight signals from the substrate and produces a briefing — what changed, what needs human attention, what's drifting. The operator reviews the briefing, approves or modifies the proposed actions, and the substrate executes the work that doesn't require a human signature. Drafts go to an outbox; the human reviews and presses send.

By evening, the substrate has captured the day's decisions, conversations, and changes. The next morning, the loop runs again, smarter than yesterday.

What the human still does

What the AI does

The three risk gates

Three constraints make this safe rather than reckless: the audit log captures every command (append-only, hash-chained, on hardware we control); the substrate refuses to type passwords or 2FA codes (credentials stay with the human); and destructive operations gate through an outbox for explicit approval (no silent `rm -rf`, no auto-send).

What this means for your business

The operator-substrate pattern isn't unique to a SaaS company. The same structure applies to any business where most of the day-to-day work is information-handling rather than physical operations: professional services, advisory, software, content, financial services. If you're curious whether the pattern fits your business, get in touch.
