The check layer for high-stakes AI work.

AI made unfinished thinking look finished. Superuser is building the pre-send layer that catches the gaps — in the numbers, claims, assumptions and caveats — before work reaches a client, board, boss or market.

Why now.

AI adoption outran AI assurance

Every knowledge worker now ships AI-assisted output. Almost no one verifies it before it reaches a client, board or regulator. The drafting got automated; the checking didn't.

The moat is the referent

We don't grade opinions. Every check is tied to a source the user supplied — numbers, clauses, citations. Code proves the facts; AI only reviews the words. That's defensible and hard to fake.

Land in one wedge, expand across work

We start where the cost of a wrong number is highest — accountancy commentary — then extend the same engine to legal, research, consulting and sales.

Where we are

An honest stage report

We're early and deliberately so. The product is built, the verification engine works, and we're opening founding pilots with UK accountancy firms to lock in week-0 baselines and provable before/after deltas. We'd rather show you a real pilot than a vanity metric.

That discipline is the point: a product built on "provable, not made-up" can't lead with invented traction. The proof is the pilots.

The opportunity

A horizontal engine, one vertical at a time

The same engine that checks a management-accounts commentary checks a contract clause, a research citation, or a sales commitment. Each vertical shares the core — a verifiable referent and a conservative, human-in-the-loop verdict — so expansion compounds rather than restarts.

Talk to the founders

If you back category-defining infrastructure early, we'd like to show you the engine and the pilot pipeline.
