Unified financial close and planning platform for enterprise
OneStream is an enterprise financial platform that unifies financial close, consolidation, reporting, and planning in a single extensible solution, eliminating the need for multiple EPM point solutions. Founded in 2010 and public since 2024, OneStream serves over 1,400 large enterprises with a platform that handles consolidation and close alongside budgeting, forecasting, and reporting. The MarketPlace provides 150+ pre-built solutions extending the core platform for specialty use cases. OneStream's extensible dimensionality handles complex enterprise structures—multi-entity, multi-currency, and multi-GAAP requirements—within a single model. Financial planning models connect directly to close and consolidation data, ensuring plan vs. actual comparisons use consistent definitions. AI-powered forecasting (Sensible ML) provides machine learning models for financial forecasting integrated within the planning workflow. The platform's single application approach eliminates integration between separate close, consolidation, and planning tools. OneStream competes primarily against SAP BPC, Oracle Hyperion, and IBM Planning Analytics in the large enterprise EPM market. Its modern cloud architecture, compared to older on-premise alternatives, and its unified approach have driven rapid growth. Gartner consistently rates OneStream as a Leader in Cloud Financial Planning and Analysis Solutions.
