OneStream and Microsoft have announced a major expansion of their strategic partnership to accelerate the adoption of artificial intelligence within finance departments. The announcement was formalized on May 15, 2026, in a joint press release highlighting a clear ambition: to make AI a central driver of transformation for the Office of the CFO.
As part of this strengthened collaboration, the two companies plan to invest jointly over the next three years to develop infrastructure, use cases, and artificial intelligence capabilities dedicated to corporate finance.
An alliance focused on transforming the finance function
This partnership builds on the complementarity between OneStream’s financial AI capabilities and Microsoft’s cloud and AI infrastructure, particularly Azure and Microsoft Foundry.
The stated objective is to help finance departments leverage their data more effectively in order to improve:
- strategic planning,
- financial forecasting,
- reporting,
- data analysis,
- and financial process automation.
According to the two partners, this new phase of collaboration should enable finance teams to transform growing volumes of data into reliable, actionable insights more quickly.
Three major areas of development
The agreement is based on three strategic priorities.
Strengthening AI infrastructure
OneStream plans to expand its computing capabilities on Azure infrastructure to support its financial AI technologies, including:
- SensibleAI quantitative forecasting models,
- generative algorithms,
- and AI agents designed for finance functions.
This development should address the growing needs of large enterprises in terms of financial data analysis and processing.
Developing new use cases integrated with Microsoft 365
The two groups also aim to develop new use cases connected to the Microsoft ecosystem, including:
- Microsoft 365 Copilot,
- Excel,
- Teams,
- and the entire Microsoft 365 suite.
The ambition is to enable finance professionals to access advanced analysis, forecasting, and anomaly detection capabilities directly from their everyday work tools.
Accelerating the global adoption of financial AI
The partnership also includes commercial and support initiatives designed to help companies modernize their financial systems and migrate to AI-driven workflows.
The two parties are particularly targeting organizations seeking to replace legacy financial environments with more integrated and automated platforms.
A shared vision of AI for CFOs
In the press release, Tom Shea, co-founder and CEO of OneStream, emphasizes that finance departments are entering a period in which AI is becoming an essential tool for addressing economic volatility and improving decision-making speed.
For her part, Katy Brown highlights Microsoft’s commitment to strengthening enterprise capabilities through AI-driven platforms that can transform data into a strategic advantage.
Enhanced integration of AI agents
The announced developments also include deeper integration of OneStream’s SensibleAI agents within Microsoft tools.
Users will therefore be able to perform:
- advanced financial forecasting,
- natural-language analysis,
- and financial anomaly detection directly in Excel, Teams, or Microsoft 365 Copilot.
This approach illustrates the two companies’ desire to bring AI use cases closer to finance teams’ everyday work environments.
Further announcements expected at OneStream Splash 2026
The technical details and next innovations related to this partnership will be presented at the OneStream Splash User Conference and Solutions Expo, held from May 18 to 20, 2026, in Orlando.
The event should enable customers and partners to discover more concretely the future integrations between OneStream technologies and Microsoft’s AI ecosystem.
