VERRIX is built by Human Machines Group LLC.

Geoff Gibbins
Founder, Human Machines Group LLC
Geoff Gibbins spent a decade building AI advisory products at the institutions that manage the retirement savings, investments, and financial decisions of millions of people — Vanguard, Citi, UBS, and Mastercard. At Vanguard he was directly involved in the design and development of Digital Advisor, one of the first institutional robo-advisory products in the US.
Building those systems from the inside, one question came up repeatedly: how do you know whether to trust an AI advisory response before it reaches a client? There was no good answer. No validated methodology. No production tool.
Human Machines Group LLC was founded to build the answer.
The company
Human Machines Group LLC was founded in 2025.
VERRIX is the company's primary product — a platform for measuring whether AI financial advisory responses can be trusted, built on the first pre-registered behavioral study of AI financial advisors.
The company is independent. The research is pre-registered and conducted without external funding. The products are built on the same validated methodology as the published research.
Human Machines Group LLC is based in the United States.
