EY vs Ekimetrics: 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.
Ekimetrics
Ekimetrics has worked from Paris since 2006 and has more than 400 data scientists and consultants. Its advice centers on measurable return: marketing mix, customer value, and sustainability metrics. That focus helps a CFO judge AI spending, though it covers a narrower field than a general advisory firm. It bought customer analytics company Actable in February 2026.
