EY is rolling out agent-native development across its global engineering organization with Factory, deploying Droids to more than 5,000 engineers in one of the largest enterprise deployments of software development agents in production today.
EY is rolling out agent-native development across its global engineering organization. Over the past six months, EY has deployed Factory's software development agents to more than 5,000 engineers, making this one of the largest enterprise deployments of software development agents in production today.
This rollout reflects a shift in how engineering work is carried out inside enterprises. Rather than using AI as a lightweight assistive layer, EY has embedded Droids across its software development lifecycle, allowing parts of engineering workflows to be delegated while still meeting enterprise requirements for quality and security.
For agents to operate in production and daily workflows, they must operate inside the systems engineers already rely on. At EY, Droids run directly within existing development environments, including GitHub, Jira, Slack, and internal DevOps tooling. This allowed Factory to quickly take on execution-heavy work such as refactoring, code changes, and documentation updates across large repositories.
In this revised workflow:
This enables true delegation without introducing parallel workflows or bypassing established review processes.
At enterprise scale, engineering work takes place in long-lived, interconnected codebases shaped by years of development. Droids are designed to operate in this environment by drawing on a shared knowledge graph that captures organizational context and historical codebase structure. This allows Droids to implement complex changes across repositories while preserving enterprise standards and institutional knowledge.
"Bringing Factory's Droids into our ecosystem allows us to quickly solve for the technical debt, and lack of automation and consistency across large codebases, a problem we're seeing across all enterprises when it comes to accelerating their AI capabilities. We're making the Droids available firm-wide because they have become a true cornerstone of scalable software strategy. The Factory team took our partnership even further and made sure we can harvest the data we need to track impact with our custom-built performance index tool."
The initiative is led by Stephen Newman, EY's Global Head of Engineering, and Martin Nicolas Ausilio, Director of Engineering. Supported by EY's Customer Engineering organization, the deployment will continue expanding across additional business units and regions throughout 2026, embedding agent-native development more deeply into EY's global delivery model.
"At EY, technology transformation is a cornerstone of our strategy. Factory's Droids enable us to accelerate innovation and deliver new capabilities faster than ever while maintaining the security and rigor that define how we operate globally."
"Our partnership with EY represents a significant milestone in how software development agents are changing the way enterprises operate," said Matan Grinberg, co-founder and CEO of Factory. "There is concrete and dramatic ROI to be found in agent-native development, and distinguished enterprises like EY are leading the charge in realizing that value today."
EY's deployment demonstrates how agent-native development can be adopted at enterprise scale. By integrating agents directly into production workflows and holding them to the same standards as engineers, EY has established a repeatable model for adoption that maintains engineering quality while materially increasing velocity.
The practices EY has put in place now serve as a reference point for other enterprises evaluating how to introduce agent-native development across their engineering organizations.
