GMO Reduces Financial Reporting Review Time by 60% with Review AI

The Challenge

Scaling Fund Operations Without Compromise

As a leading asset manager, Grantham, Mayo, Van Otterloo & Co (GMO) faced growing complexity in financial reporting. Their manual review process relied on Excel spreadsheets, requiring hours of data extraction across 200+ documents. As reporting demands increased, the need for a scalable, automated solution became clear.

"We had a robust manual process, but with multiple drafts per fund and increasing complexity, we needed a solution that could scale and save our team time—without compromising accuracy."

— Tara Pari, Head of Fund Reporting, GMO

Where Legacy Approaches Fall Short

  • The existing Excel-based process created inefficiencies
  • Manual data entry overload: Team members spent hundreds of hours inputting and consolidating data across hundreds of documents instead of analyzing it.
  • Repetitive manual review: Time consuming to review checks for every draft 
  • Limited collaboration: Individual workbooks meant limited visibility, making it difficult to leverage historical reviews, extract insights into common issues, or identify inconsistencies across funds.
  • Cumbersome audit review: Aggregating data from various locations adds complexity and inefficiency to the auditing process.
