What believers are saying

  • Fiscal 2025 revenue reached $601.9 million, up 23%, with subscription revenue up 28%.
  • Q4 2025 free cash flow hit $95.6 million, and non-GAAP margin rose to 5%.
  • Cox Enterprises adopted SensibleAI Agents, validating workflow automation inside large finance teams.

What critics are saying

  • Hg's April 1, 2026 buyout ended public-market scrutiny; employees now face private-equity targets.
  • Sonal Rana's February 20, 2026 lawsuit attacked merger disclosures, forcing distraction until closure.
  • If Microsoft embeds finance planning deeper into Excel and Copilot, OneStream loses its wedge.

What makes OneStream unique

  • May 19, 2026: SensibleAI Agents and Finance Agentic Layer extend finance AI with governance.
  • OneStream's 1,800-customer base and Fortune 500 penetration harden switching costs across complex enterprises.
