Success for private middle market dealmakers ultimately hinges on quality data.
To stay competitive, investors have to maintain a steady flow of deals. That means they have to:
- Find companies that fit their investment criteria
- Evaluate those companies’ strategic and financial operations to see if and how the deal would add value
But this is often much more difficult than it sounds. Private middle market data is hard to find, and the quality of what is available from company databases is often lacking. Large language models (LLMs) like ChatGPT and Midjourney can make the process even more challenging with inaccurate or outdated information.
To avoid these challenges, some firms with deep engineering expertise and resources opt to build their own proprietary M&A data infrastructure. This allows them to tailor a solution to their exact needs. Having exclusive data can also give firms a competitive edge.
So what exactly does it take to build your own M&A data ecosystem and how do you know if this path is right for your firm?
We dig into these questions — and more — below.
What Is M&A Data Infrastructure?
First things first – M&A data infrastructure is the custom system of hardware, software, networks, services, and policies that enable data storage, security, and sharing. The core types of data infrastructure include on-site, cloud-based, and a hybrid between the two.
Virtual Data Rooms vs. M&A Infrastructure
M&A infrastructure and databases are not unlike virtual data rooms (VDRs), which provide an encrypted, centralized hub for managing sensitive deal information. VDRs have become essential for M&A, Initial Public Offerings (IPOs), company audits, and collaborative business projects. secure digital platform used to store, manage, and share confidential documents during a merger or acquisition.
Essential features of a VDR include security, automatic categorization, redaction, flexible permissions, optical character recognition (OCR), translation, watermarking, data backup, Q&A, analytics, and smart bulk upload.
The key difference between the two is the stage of dealmaking. VDRs typically come into play during later phases of dealmaking such as due diligence, acquisition, and legal preparation -- whereas M&A data infrastructure can be useful earlier in the dealmaking process with sourcing, screening, networking, list building, and industry research.
Where Most Prebuilt Solutions Fall Short
While there are a plethora of company databases and deal marketplaces available for purchase, most of them are not built specifically for M&A workflows.
For example, ZoomInfo offers a contact database with over 150M records, but information on company owners, founders, and principles — which are crucial for M&A conversations — is limited.
Company databases like Sourcescrub are limited in how granular their data can get because they rely on broad industry classifications and human processes. Pitchbook has a wealth of deal data for upper-middle market VC- and PE-backed companies, but it also has a massive blind spot when it comes to the middle market.
Why Investor Teams Build Proprietary Data Systems
If executed correctly, building proprietary systems can fill in these gaps and bring private middle market investors the exact data they need.
To continuously identify new targets, and to get to them before their competitors do, dealmakers need to be able to dig into niche markets that fit their investment thesis. By building a proprietary M&A data ecosystem, investors can zoom in on the areas that prebuilt solutions tend to overlook.
Having a unique in-house system also streamlines workflows for the team. Instead of having to maneuver multiple alternative data platforms to get the granularity they need, investor teams can rely on a single tool. That allows them to be more collaborative and agile, giving them a competitive edge. Reaching targets before the competition is crucial for winning deals.
Another benefit of building out a proprietary M&A data infrastructure is that investors can pitch themselves to limited partners (LPs) as users of differentiated sourcing. LPs want access to new pockets of their markets, which can yield high returns. Unique strategies help provide that.
LPs also want to back firms that can find deals at more attractive prices. If investors can make the case that their system can 1) expose them to new market segments at an advantage over the competition, and 2) integrate niche, verticalized, unique data sources, LPs will likely be more willing to open their wallets.
Some investors also choose to build their own systems for added layers of security. Instead of relying on external data storage solutions, some prefer to house their data on their own systems for full control. In-house servers can also be configured to meet specific needs, which could be a plus for investors concerned about the level of customization offered by third-party solutions.
Key Components of Modern M&A Data Infrastructure
Make no mistake — building your own proprietary M&A data infrastructure is no small feat. It’s complex, time-intensive, and expensive.
Pulling it off requires a deep bench of engineering, devops, data science, and AI and machine learning (ML) capabilities. The cost of assembling that pool of resources alone prohibits many firms from buying their own system. Consider that the salary range for a single big data engineer is $150,000 to $250,000, depending on their level of experience.
Your team will also need to license datasets to achieve the level of granularity you need to identify the right investment targets and conduct due diligence. These could include:
- Relationship data, including a history of your first-party data from your CRM, showing interactions with target companies and similar companies
- Company rankings, such as “Best Company” lists
- Annual reports, SEC filings (for public companies or public comparables)
- M&A transactions and past deals
- People data, such as employment history
- Public records and government disclosures
- Industry specific sources like web traffic, consumer reviews, credit card data, healthcare claims, and more
Add up the cost of paying multiple engineers, licensing multiple datasets, and maintaining the infrastructure to make the whole thing work, and you’re easily at $1M.
Step-by-Step: How to Build Your Own M&A Database
If you’re spending that kind of money, you want to minimize costly errors and delays. To make sure the building process is as time- and cost-efficient as possible, here are some key steps that your team should take:
- Develop a clear, specific vision for the database’s end result. Who will use it and how will they use it? Define specific criteria and parameters for measuring success so that you can validate each release against those metrics.
- Define what a “company” is for your purposes, and build a set of companies based on that definition. Make sure the set does not contain duplicates resulting from foreign countries, mergers, products under different brand names, etc.
- Identify the best source for each necessary data point and build prioritization rules to organize the data display in the system interface.
- Establish a schedule for the updates needed for each data point to achieve the desired end results.
- Create a plan to iteratively build the system, test it with internal teams, and refine the data representation based on what your test results show.
After you have sufficiently tested, adjusted, and improved your system, you’re ready to release it. Once it’s up and running, train the teams at your firm on the system and mandate that they use it for their internal workflows. This ensures that usage is consistent across your firm, driving efficiency across your dealmaking workflows.

FAQs
What is “M&A data infrastructure”?
M&A data infrastructure refers to a firm’s internal system of hardware, software, networks, services, and policies that enable data storage, security, and sharing.
How is an M&A database different from a CRM or virtual data room (VDR)?
VDRs are typically used later in the deal lifecycle after a target is already identified, and CRMs are just one slice of data necessary for the dealmaking process. M&A data infrastructure is more widely encompassing, focusinh on the earlier stages of dealmaking: finding, qualifying, prioritizing, and understanding companies as they move through your pipeline. M&A data systems power sourcing strategy rather than just managing documents and contacts.
Who should consider building a proprietary M&A database?
Firms that benefit from building their own M&A most typically:
- Focus on niche or fragmented markets
- Compete heavily on proprietary deal flow
- Need highly specific data points not available in prebuilt platforms
- Have internal engineering, data, and DevOps resources
- Want a differentiated story to tell LPs around sourcing and pricing advantages
When does it make more sense to buy data infrastructure instead of building?
If your team doesn't have dedicated technical resources, a large development budget, or the ability to maintain long-term infrastructure, buying data systems and APIs is usually the better choice. For the majority of firms, licensing a flexible data platform provides most of the upside at a fraction of the cost and complexity.
