BABL AI vs West Monroe: overview
BABL AI
BABL AI was founded in 2018 in Iowa City by astrophysicist turned auditor Shea Brown, a founding member of the International Association of Algorithmic Auditors. It runs independent, criteria-based audits and certifications, starting with automated hiring tools and now covering EU AI Act risk management. It also trains auditors through its own courses. The firm is small, and its strength is a clean separation between whoever built the system and whoever checks it.
West Monroe
West Monroe has operated from Chicago since 2002, has about 2,250 people, and is partly employee-owned. A chief AI officer joined in September 2025, and in June 2026 it launched WestMonroe.ai, a set of on-demand AI agents. Its advisory starts from operations and cost, which COOs tend to like. European regulation is a thinner part of its practice.
