Case Study: Hyperion Insurance Group achieves centralized control, transparency and deeper financial reporting with OneStream Software

Hyperion Insurance Group - Customer Case Study

Hyperion Insurance Group is an international insurance broker and underwriter with over 4,500 employees operating across 30+ countries and four main divisions. After five years on Anaplan, the finance team faced reconciliation problems, limited reporting and audit capabilities, weak role segregation and a fragmented landscape of legacy systems—driving a need for stronger controls, standardized close processes and deeper, auditable management reporting.

Hyperion selected OneStream (with implementation partner inlumi) and rolled out a phased implementation for consolidation and reporting, planning and forecasting, and account reconciliations, plus MarketPlace solutions for Reporting Compliance and People Planning. By integrating OneStream with their Unit4 ERP and using its built‑in ETL and unified data model, Hyperion gained centralized control, richer dimensional reporting, guided month‑end workflows across 40 countries, improved audit trails and local-level reporting—boosting transparency, governance and user adoption.
