EY announces alliance with Rillet to provide AI-native finance transformation - with risk and controls built in

• Improves audit readiness and helps accelerate finance modernization without the disruption of a full ERP placement
• Achieves integrated transformation that combines finance, technology, and risk and controls in a single operating model
• Leverages the EY organization's finance transformation experience and EY.ai for Risk capabilities with Rillet's AI-native platform

LONDON, April 29, 2026 /PRNewswire/ -- The EY organization today announces an alliance between Rillet (Gnau, Inc.), an AI–native enterprise resource planning (ERP) and accounting platform provider, and Ernst & Young LLP (EY US) to help create a market-first relationship that embeds finance transformation, AI-native automation and risk management into a single, cohesive operating model.

The Alliance brings together EY US finance transformation, technology consulting, risk and controls and operating–model capabilities with Rillet's AI–native, general–ledger–first finance platform. Together, EY and Rillet support organizations that have outgrown mid–market ERP systems and are seeking modern, scalable finance operating models.

The Alliance seeks to help companies embed accounting logic and automation directly into core finance workflows, including journal entries, reconciliations, revenue recognition, close management and reporting.

Michael Flynn, EY-Rillet Alliance Leader, EY US, says:

"Finance leaders are navigating relentless pressure to improve speed, insight and control, while managing mounting complexity and risk. The EY-Rillet Alliance is differentiating precisely because risk management and controls aren't a separate workstream: they are woven into the transformation from the start. That's how the Alliance will help clients build finance functions that are not just faster and smarter, but genuinely resilient."

Nic Kopp, CEO and Co-Founder at Rillet, says: 

"Finance transformation has long promised speed and insight, but integrating controls has remained a persistent challenge. With EY US, we're changing that. When AI is baked into the accounting logic from the ground up, controls don't just keep pace–they become stronger, more continuous and more defensible under audit."
