  • Rising Demand for Private Market Data: The total global assets under management in private markets reached approximately $11.87 trillion in 2023 and are projected to grow significantly, highlighting the increasing importance of effective data management in this sector.
  • Challenges in Data Management: Investment firms face issues such as data fragmentation, quality control, and the need for transparency, which complicate their ability to aggregate and validate private market data effectively.

Introduction

In recent years, private markets have experienced a remarkable surge in popularity among investment managers. As firms seek to diversify their portfolios and capture higher returns, exposure to private equity, private debt, and other alternative investments has become increasingly common. According to recent reports, total global assets under management (AUM) in private markets reached approximately $11.87 trillion in 2023 and are projected to grow to $15 trillion by 2025 and more than $18 trillion by 2027. However, with this growth comes a host of challenges related to data management, particularly when it comes to mastering private market data.

The Challenge of Aggregating and Validating Private Market Data

Investment management firms aspire to treat private market data with the same rigor and standardization as public market data. However, the reality is that private market data often lacks a consistent schema or standardized identifiers, which creates significant confusion for firms trying to aggregate, master, and validate multiple sets of data from various vendors.

This lack of standardization leads to several challenges:

  • Data Fragmentation: Firms often find themselves managing data across numerous systems and platforms, making it difficult to create a unified view of their investments.
  • Quality Control: The absence of standard identifiers complicates the process of reconciling data from different sources, resulting in discrepancies and inconsistencies that can affect decision-making.
  • Investor Demands for Transparency: As investors increasingly demand transparency in reporting, firms must ensure that their data is accurate, comprehensive, and easily accessible. This is particularly critical in private markets, where data is often opaque and less readily available than public market data.
