Integrating Data Across Portfolio Companies: Best Practices and Tools

Private Equity

Last Updated: April 6, 2026

Every company operating in private equity is on a journey to become a data-driven organization. As portfolios expand and become more heterogeneous, firms need a way to connect data from portfolio companies.

Private equity firms have traditionally struggled with fragmented data across their portfolio companies. Legacy systems, disparate reporting tools and metrics, and a lack of centralized operational platforms have created organizational blind spots and hidden opportunities for value creation.

Enter data integration. 

Forward-thinking firms are working towards creating centralized data ecosystems backed by powerful analytics and scalable digital platforms.

Integrating data from portfolio companies allows firms to reduce dependency on spreadsheet-heavy reporting and transition towards continuous intelligence.

Companies like Hexaware empower private equity firms with digital engineering, data platforms, and analytics to help eliminate data fragmentation and accelerate business decisions.

Why Data Integration is Critical in Private Equity

Portfolio Complexity is Increasing Rapidly

PE firms invest across different industries, geographies, and stages of operational maturity. Each portfolio company may operate on different technologies and platforms, including:

  • ERP software 
  • CRM platforms 
  • Finance tools 
  • Data repositories 
  • Analytics software 

This variation results in a data ecosystem that isn’t connected and takes longer to analyze and report.

Access to Continuous Investment Intelligence Is Required

Investors and operating partners have realized that quarterly reporting is not enough. They want visibility into important metrics on a continuous basis. Metrics such as: 

  • Sales and revenue 
  • Operational metrics 
  • Customer acquisition costs 
  • Supply chain efficiencies 
  • Digital transformation status 

Having integrated data enables firms to monitor and report on these metrics in near real time.

Let’s take a look at what fragmented data looks like in private equity.

The Anatomy of Fragmented Data in Private Equity

Fragmented data exists when data points are siloed within systems and aren’t standardized or connected to other systems.

Sources of fragmented data in private equity include:

Outdated technology: Many portfolio companies operate on outdated software systems that don’t integrate well with others.

Erratic data definitions: Different companies may understand the same metric in different ways—e.g., net revenue. 

Manually created data: Data that is logged into Excel, Google Sheets, and other forms of spreadsheets.

Lack of data standards: Each system may have its own owner, allowing data standards to diverge.

Fragmented data causes several issues that affect firms’ operational efficiency.

Issues caused by fragmented data include: 

  • Slow investment research 
  • Inability to benchmark company KPIs against other investments
  • Incomplete view of performance 
  • Missed opportunities for cost savings and revenue generation
  • High operational costs 
  • Increased reporting time and effort due to messy data
  • Loss of confidence in reporting 
  • Greater risk of human error in spreadsheet-based reporting

Core Principles of Data Integration in Private Equity

Standardized Data Models

Data integration does not imply that all your portfolio companies should use the same systems. However, you should strive to build a centralized data layer that gives you access to information.

Common Data Definitions 

Common definitions should be agreed upon. For example, what does revenue or EBITDA mean to your organization? These definitions allow you to easily compare investments against each other.

API-first Integration 

Integration should not be done by forcing systems to communicate with each other. Adopting a strategy where integrations are powered by APIs allows for flexibility when connecting systems.

Cloud-native Infrastructure

When building your tech stack, try to use cloud platforms. They offer scalability, security, and allow you to access your data in real time.

Designing a Tech Stack for Data Integration 

An important part of building your data integration strategy is ensuring that your tech stack allows for data to be integrated and analyzed across your portfolio companies.

The following is an example tech stack that allows for data ingestion, processing, and analytics:

Data Ingestion Layer

Every modern tech stack should have a layer that automates the collection of data, such as: 

  • ERP data 
  • CRM data 
  • Finance data 
  • Market data 

Tools should be able to extract this data and transform it into a format that you can store.

Data Storage and Processing Layer

Once your data is extracted and transformed, it needs to be stored somewhere. This is where cloud data lakes and warehouses come in.

Advantages of having a cloud data lake include:

  • Ability to scale 
  • Highly processable 
  • Easy to access

Integration Middleware Layer

Middleware acts as a glue that connects your software applications. Using an integration platform as a service (iPaaS), you can create workflows that utilize APIs to integrate your systems in real time.

Analytics Layer

You wouldn’t have collected data if you weren’t going to do something with it. Using a dashboard tool, you can visualize your data for your investment teams.

Automation and AI Layer

With machine learning, you can build models to forecast future revenue, analyze risk, and optimize performance.

Best Practices for Integrating Data Across Portfolio Companies

Align Data Integration With Your Strategy

Every integration effort should start with a strategy. Things to define in your strategy include: 

  • Your objectives 
  • Data owners 
  • Data governance 
  • Target architecture 

Create a Uniform Set of KPIs

KPIs are generally unique to each investment. However, creating uniform definitions allows you to benchmark portfolio companies against each other. Some examples for which you can create uniform KPIs include: 

  • Revenue 
  • EBITDA 
  • Customer churn 
  • Cost of operations 

Use a Modular Approach

Changing your systems all at once can be expensive and time-consuming. Approach your integration efforts by integrating one system at a time.

Invest in Data Governance

Data governance includes, but is not limited to:

  • Data quality 
  • Permissions and access 
  • Regulatory compliance 
  • Metadata management 

Enable Self-service Analytics

Analysts should not have to wait weeks for the data team to retrieve data. Building dashboards that allow your teams to access data will enable quicker decisions.

Private Equity Data Integration Use Cases

Below are some common ways investors integrate data across their portfolio companies:

Deal Sourcing and Screening

By integrating your market data with your portfolio data, you’ll have better visibility in identifying deals.

Due Diligence

Access to integrated data will help you spend less time digging through documents and more time working on the deal.

Portfolio Monitoring

Integrated data will allow you to create dashboards that give you real-time insight into your portfolio company’s performance.

Exit

Just like due diligence, access to integrated data will save you time when you’re planning your exit.

How AI Can Help You Eliminate Fragmented Data

AI solutions can help accelerate your data integration strategy by:

  • Automatically mapping out data fields
