Validation you can put in front of an examiner requires a validator with nothing to sell you.

Prominent Advisory Group is the independent model-validation practice of Ace Vo, PhD. The practice does one thing: test LLM and NLP systems used in financial document analysis against human ground truth, and document the results to model-risk standards.

Background

Ace Vo is an Associate Professor of Information Systems and Business Analytics, with research spanning applied machine learning, text analytics, and decision support systems. His work has appeared in Decision Support Systems, Information Systems Frontiers, the Journal of the Association for Information Systems, JMIR, and Communications of the AIS, among others.

He is the lead author of one of the first large-scale, peer-reviewed benchmarks of frontier LLMs against human-annotated ground truth on regulatory filings — the study this practice's methodology comes from. Alongside academic work, he has spent years in industry engagements on production NLP systems, including large-scale clinical and legal text pipelines, which is where the gap between benchmark claims and deployed reality became impossible to ignore.

Independence

This practice builds no models, resells no AI products, and accepts no vendor referral fees. Fees are fixed and agreed before testing begins, and thresholds are pre-registered — so no finding, favorable or not, changes what you pay. The academic affiliation above is provided for professional identification; engagements are conducted solely through Prominent Advisory Group.

Working with the practice

Engagements begin with a single 30-minute scoping call and run on a fixed fee with a 10-business-day standard turnaround. Communication is asynchronous by default — written findings, documented methods, one walkthrough session at delivery.
