EY and Microsoft are putting more than $1 billion behind a bet that most companies still don’t know how to actually use AI. The five-year joint investment, announced on May 21 in London, is designed to help enterprise clients move AI projects from the “cool demo” phase into full-scale production systems.
The partnership pairs Microsoft’s Forward Deployed Engineers with EY’s industry specialists to build secure, sector-specific AI solutions. Target industries include finance, healthcare, energy, consumer and retail, government, and industrials.
EY is eating its own cooking first
Before selling AI transformation to clients, EY plans to transform itself. The firm is positioning as “client zero,” deploying Microsoft 365 E7 and agentic AI features across its global workforce of more than 400,000 employees.
EY Global Chair and CEO Janet Truncale framed the challenge not as a technology problem but a people problem. Most business leaders already expect AI to reshape work, she noted. The harder part is preparing people to actually use it.
Truncale also made a point that will matter to workers watching this space closely: AI transforms roles and boosts productivity without reducing headcount.
What the partnership actually covers
The investment is structured around moving companies past the pilot stage. In English: lots of enterprises have built small AI proofs of concept that impress the board but never make it into daily operations. This partnership is designed to close that gap.
Microsoft’s contribution centers on its Forward Deployed Engineers, a team model where Microsoft embeds technical staff directly with client organizations rather than offering remote support. Combined with EY’s consulting army, the idea is to provide both the technical infrastructure and the change management expertise needed to make AI stick.
The “agentic AI” component deserves a quick translation. Agentic AI refers to systems that can take autonomous actions on behalf of users, going beyond simple chatbot responses to actually executing multi-step tasks. Think of it as the difference between asking an AI to draft an email and asking it to handle your entire inbox triage, schedule follow-ups, and flag urgent items without human intervention at each step.
EY and Microsoft have worked together for years, with prior collaborations producing co-developed solutions and joint industry awards. This new commitment represents a significant escalation of that relationship, moving from project-level cooperation to a strategic, multi-billion-dollar alignment.
