ABOUT
Your name is on the work. Mine is on the checker.
Superuser exists because AI made unfinished thinking look finished — and someone has to check before it ships.
Joel Davis, founder
I've spent 24 years helping teams at the brands below adopt digital, performance marketing, experimentation and AI. The pattern that kept repeating: the draft got faster, the checking didn't — and the errors that slipped through weren't typos, they were the number the room relied on. Superuser is the check I kept wishing existed: code that proves the numbers, AI that reads the words, and a verdict you can defend.
HOW IT'S BUILT — THREE RULES
Code does the maths. Every sum, variance and streak is recomputed deterministically — never estimated by a model.
Quotes are verbatim or blocked. Every "draft said" is string-matched against your document before you see it.
Honest coverage. Every report ends with a receipt of what was checked — and what couldn't be verified is marked, never asserted.

CHECKS CONSISTENCY AGAINST SUPPLIED EVIDENCE — NOT LEGAL OR AUDIT ADVICE.
