EY vs Elder Research: overview
EY
EY was formed by the 1989 merger of Ernst & Whinney and Arthur Young and employs about 400,000 people. Its advisory teams cover responsible AI, AI risk, and compliance programs, and its technology risk leaders have spoken publicly about how far real AI assurance still has to go. That candor is useful for buyers who want an honest view of what can be certified today. Like the rest of the Big Four, it sells implementation as well.
Elder Research
Elder Research has advised on analytics since 1995 from Charlottesville, Virginia, and has around 170 staff. ManTech, owned by Carlyle, bought it in December 2025. Its readiness work rests on decades of hands-on modeling, so its view on whether your data can support a use case is grounded in practice. European regulation is outside its usual territory.
