OneStream Surpasses 600 EMEA Customers and Triples AI Adoption

OneStream triples AI customer base and deepens investment across EMEA as Founder and CEO Tom Shea presents governed Finance AI framework at Web Summit

LISBON, Portugal, Nov. 6, 2026 /PRNewswire/ -- OneStream, the AI operating system for modern Finance that unifies core financial and operational processes, embedding the governance, context, and control required to make AI work for Finance, today announced it has surpassed 600 customers in EMEA and more than tripled its Finance AI customers in the region since the end of 2025. The news comes as Founder and CEO Tom Shea takes the stage at Europe's biggest tech event, Web Summit 2026, to detail a framework for auditable, contextualized AI for Finance.

"CFOs across Europe are realizing the real advantage of AI isn't the smartest model – it's AI operating within a strict framework of financial governance," said Tom Shea, Founder and CEO at OneStream. "AI is the reasoning engine, but enterprise software must be the trust engine. Our acceleration in EMEA proves leaders want a financial control tower that delivers answers they can act on without operational risk. We will continue investing heavily in the local teams and partners helping them build this secure foundation."

Accelerating EMEA Momentum
Over the past 12 months, OneStream helped more than 100 new EMEA customers modernize their tech stack and passed 600 customers in the region, with customers in more than 35 markets. Customers span industries including manufacturing, retail, banking and financial services, pharmaceuticals, and oil and gas. Notable EMEA customers include Grupo ACS, Delivery Hero, and Swatch.

Customers across the region are using OneStream to modernize core Finance processes, replacing fragmented legacy systems with a unified platform for financial close, consolidation, reporting, and planning. This unified foundation helps teams keep pace with complex regulatory requirements across EMEA, while providing the governed data necessary to leverage AI for accelerated insights and real business value.

OneStream's Finance AI adoption is growing alongside its broader platform growth. The number of EMEA customers using OneStream's Finance AI has more than tripled since the end of 2025.

To support this sustained regional acceleration, OneStream continues to scale its operations and partner ecosystem, building on its established regional presence across London, Manchester, Paris, Amsterdam, and Madrid.

"Finance leaders across EMEA are modernizing their core Finance platforms to keep pace with complex regulation and move faster," said Matt Rodgers, EVP, EMEA at OneStream. "That modernization is what enables them to take AI from pilots to enterprise-wide deployment, because it gives them a data foundation they can actually trust. Our momentum in the region underscores a fundamental shift toward governed, unified enterprise platforms that deliver real business value."

Building Trust in AI Agents

Shea will appear in a featured fireside chat titled "Why AI and SaaS Need Each Other" on Thursday, Nov. 12, at 1:25 PM on Stage 7. Moderated by Hope King, Founder of Macro Talk, and featuring Luminance CEO Eleanor Lightbody, the session will examine the evolving role of enterprise software as AI agents take on increasingly complex workflows. Shea will detail how governed data, strict access controls, and transparent audit trails determine how safely organizations can let autonomous agents act on their own.
