OneStream, the leading enterprise Finance management platform that modernizes the Office of the CFO by unifying core Finance and operational functions including financial close, consolidation, reporting, planning and forecasting announced the successful completion of its acquisition by Hg, a leading investor in European and transatlantic technology and services businesses. Minority investors include General Atlantic, a leading global investor, and Tidemark, a leading technology investment firm.
The all-cash transaction values OneStream at approximately $6.4 billion in equity value. With the completion of the transaction, OneStream’s Class A common stock has ceased trading on the NASDAQ.
Backed by investors with deep expertise in scaling category-leading platforms for the Office of the CFO, OneStream is now privately held, with Tom Shea continuing to serve as CEO and the current OneStream leadership team remaining in place.
“Following an exceptional year of growth, including more than doubling our AI customers year over year in 2025, today’s news marks an exciting next step for OneStream,” said Tom Shea, founder and CEO of OneStream. “We believe the leaders in Finance AI will be defined over the next 24 to 36 months, and we are making deliberate, long-term decisions to lead at this critical inflection point. Our strategy, leadership, and commitment to customers and partners remain at the center of this. With Hg’s partnership, we are well positioned to accelerate innovation, scale globally, and deliver even greater value to Finance leaders around the world.”

OneStream continues to lead Finance AI and is uniquely positioned for tremendous growth in the future. We’re excited to be a part of their continued expansion, innovation and value creation.”
