OneStream sells a cloud-based Corporate Performance Management (CPM) platform, called the Digital Finance Cloud, to CFOs and finance teams at large enterprises and mid-market organizations. The platform handles financial close and consolidation, FP&A (budgeting, forecasting, and scenario modeling), and reporting and analytics. The core pitch is consolidation: OneStream replaces a fragmented mix of legacy CPM systems, spreadsheets, and point solutions with a single unified platform built on a common data model, giving customers a single source of truth and eliminating manual reconciliation. OneStream sells primarily through a direct sales force targeting CFOs, supplemented by roughly 300 implementation partners including Accenture, IBM, KPMG, and PwC. Revenue is primarily SaaS subscription (~85%+ of total), with a small and shrinking legacy on-premise license component and a modest professional services business (~6% of revenue) that OneStream is intentionally shifting to partners. The business follows a land-and-expand model: OneStream typically lands as the system of record for core finance, then expands into adjacent use cases and adds users over time, reflected in net dollar retention of 113% and gross retention of ~98%. OneStream is also layering AI products — SensibleAI Forecast, SensibleAI Studio, and agentic AI tools — as usage-based add-ons to the core platform. Growth vectors include displacing aging Oracle Hyperion and SAP installs, a pre-packaged mid-market offering (CPM Express), international expansion in Europe, and extending the platform into operational planning use cases like workforce and supply chain planning.
