About

Led by Kevin Liggett — twenty-plus years designing enterprise systems for complex regulated environments. Correctness, provenance, and auditability as first-class requirements. Based in Canada, serving clients globally.

Our Approach

Evidence-first AI — zero trust in generated content

AI is a tool, not a source

AI analyses evidence — it never generates facts. Every conclusion traces back to a published, citable reference.

Authoritative sources only

Published databases and peer-reviewed literature — recognized sources, not web scrapes. Every score traces to verifiable, published data.

Zero trust in AI output

A hard grounding gate blocks any output that lacks traceable evidence provenance. No hallucinated citations, no unverifiable claims.

How can we help?

Product questions, enterprise inquiries, partnership opportunities — we reply to every message.
