Hundreds of agents do the work across every function. Fairy tracks every decision they make — and routes the calls they can't make alone to the fallback: your team, or a vetted expert. Build with AI; never run without a backup.
AI runs the work · humans are the fallback
Start here — live today
The sign-off gate for AI-written code. When your agents touch payments, auth, or migrations, the merge blocks until a named senior engineer signs a verdict — inside 24 hours, one flat price, no hire. It's a required check in the GitHub flow you already have, and every sign-off becomes part of the record above.
Routed to the right one for the stakes. Four you already have — the fifth, a network of vetted experts on demand, is the one you can't build yourself.

How it works
Agents do the work across a function. When a decision needs a second opinion, Fairy gets it from the right place — your company's memory of past calls, your team, or a vetted expert — then records the outcome as precedent, so the next one like it clears on its own.

How Fairy keeps you accountable
Godmother scores each AI action for risk and won't let the consequential ones — money, data, access, destructive changes — proceed unowned. It clears the routine and routes the rest to a person, in real time. Nothing important happens silently.
Your team handles what it can. When a call needs judgment you don't have in-house, Fairy brings in a vetted expert — on demand, wired into the decision, not a consultant you go hunt down. It's the second opinion no approvals tool can give you, and every one becomes your company's memory.
Destructive, financial, access-control, and PII actions are held for a human by a deterministic floor the model cannot switch off — 89% on our 9-case audit. Add your own rules in Policy Studio — they can only tighten it, never loosen it.
Every decision, who owned it, the cost, and how it turned out — one audit-ready system of record. Your company's memory of every call it made, human-signed.
Every outcome is scored, so autonomy is earned, not assumed. Agents that hold up get more room; the ones that don't get reined in — and human review shrinks to only what truly matters.
Point any agent — built anywhere, on any model — at Fairy and it's accountable from the first call. Stand up new agents across a function too, governed from day one.

The thesis
For fifty years, software drove the cost of execution toward zero. AI finishes the job — soon every company runs on thousands of agents. What stays scarce is judgment: knowing which calls an agent can make on its own, and when to get a second opinion. That's the whole job now — and it's the one thing you can't hand to the agents themselves.
Fairy is that judgment. Agents run the business; the calls that matter get a second opinion from the right place — your memory, your team, or a vetted expert. And every second opinion becomes precedent, so you need fewer of them over time. Humans stay accountable; the company gets smarter as it runs.
