OneStream was founded by the inventors of FDM (formerly Upstream) and Hyperion Financial Management (HFM). Their solution, OneStream XF, is a single, unified Corporate Performance Management software platform for financial consolidation, planning and analytics which enables your business to be agile and adaptable to change while reducing your total cost of ownership. The key difference to most of the other 'big vendor' competitor solutions is that it is truly one unified solution eliminating the need to install, build, learn, integrate and maintain multiple products or applications.

OneStream XF is an extensible platform that can easily accommodate additional solutions such as Account Reconciliations, Tax, Close Management, Workforce Planning, Profitability and Cost Analysis and more with no additional software, modules or applications to buy or install, integrate, deploy and learn.
