Private company research

An acquisition target appears relevant to your investment mandate, but the available information is thin. Its website describes the product, a transaction announcement identifies the owner, and a database provides a few financial estimates. You still need to understand why customers buy, how the business competes, and whether the opportunity deserves more time.

Private company research helps deal teams answer those questions before full data-room access. At this stage, the task is to build an informed initial view, identify uncertainty and decide what to investigate next.

This guide sets out a practical approach for private equity (PE) investors and consultants, with examples of where Third Bridge's company intelligence and expert insights fit into the process.

What private company research should establish

Private company research combines available documents, company and market data, and relevant industry perspectives to understand a privately held business. The depth of information varies by jurisdiction, company size, and ownership structure.

Before commissioning detailed diligence, a team should be able to explain what the company sells, who pays for it, how demand is generated, and what could threaten its position. It should also know which parts of that explanation remain assumptions.

An initial research note should distinguish reported facts, third-party estimates, expert observations, and the team's own interpretation. A revenue estimate becomes less useful when its date, perimeter, or underlying method is unclear.

Establish the company perimeter

Start by confirming which business you are researching. A trading name may cover several legal entities, while a group's consolidated figures may include operations outside the proposed transaction.

Review the company's website, available registry filings, ownership announcements, and relevant public documents. Capture the legal and trading names, major products, geographies, and any acquisitions or disposals that change the business perimeter.

Maintain a short source log. Record the date, the entity covered, and the limitations of each source. If two databases give different revenue figures, investigate whether they refer to different years or entities before choosing between them.

This work prevents a common problem in early research: producing a detailed analysis of a business that does not match the asset under consideration.

Map the business model and value chain

Next, establish where the company sits between suppliers and end customers. Does it manufacture a product, distribute someone else's, provide implementation services, or operate an ongoing service relationship? Who specifies the purchase, who controls the budget and who can replace the provider?

Third Bridge's Library includes company profiles and information on customer, competitor, and supplier relationships. Those connections provide a starting point for investigating how a target's market works.

Use the value chain to identify the questions that matter. For a specialist distributor, purchasing relationships and availability may be central. For a software implementation business, the relevant questions may concern technical capability, access to skilled staff, and dependence on a platform ecosystem.

The purpose is to connect the company's stated offering to the commercial relationships that generate revenue.

An illustrative screening decision

Consider a hypothetical PE team researching a privately owned provider of enterprise software implementation services. The company's website highlights certifications and customer logos. Neither explains how much work comes from new deployments, upgrades, or ongoing support.

The team could use existing company and sector interviews to understand the service model and form an initial question set. It may identify that the investment case depends on recurring customer work, while the available information mainly describes completed projects.

That gap changes the expert brief. A broad conversation about the software market would be less useful than a discussion with someone who understands how customers select implementation partners and allocate repeat work.

Third Bridge's expert calls can connect the team with relevant perspectives sourced against that brief. The research can then examine the conditions under which customers retain a provider, change suppliers, or bring work in-house.

This illustrative process produces a better-defined screening question and a more focused diligence plan. It does not establish the target's actual revenue mix, which still needs appropriate company evidence.

Investigate commercial quality through specific questions

Early research should concentrate on assumptions that could change whether a deal progresses. The following questions help organise that work.

Why customers choose the business

Investigate the buying criteria that matter in the relevant segment. These might include reliability, technical capability, service coverage, or the effort required to switch. Ask how those criteria affect actual procurement decisions.

A company's claim that it offers a critical service needs explanation. Is the service essential to the customer's operations? Are alternatives limited? Does changing provider create a meaningful implementation burden? Each answer points to a different source of commercial resilience.

How the company competes

Identify direct competitors and other ways customers can meet the same need, including internal provision. Examine whether competitive strength varies by customer size, geography or product line.

An expert with deep experience in one segment may offer little visibility into another. Keep their perspective attached to the area they know.

What supports the growth case

Separate market growth from share gains, pricing, and expansion into new services. Ask what must happen operationally for each part of the plan to succeed.

If growth depends on a new customer segment, look for evidence about its buying process and service requirements. Success with an existing customer base may not transfer automatically.

Use estimates without creating false precision

Private-company financial information can be incomplete. Expert perspectives may help explain business drivers or provide context for an estimate, but they should not be presented as audited company results.

Record the basis of an estimate, its date, and the expert's relevant experience. Where evidence is limited, use a range or leave the question open. Several similar estimates may still share the same underlying source.

For example, an observation about typical staffing requirements can inform a discussion of operating constraints. It cannot establish the target's exact margin without further evidence. Make the distinction visible in the screening note and carry the question into diligence.

Turn the gaps into a focused research brief

After the first research pass, write down the unresolved questions in order of their importance to the decision. For each, specify the evidence needed and who could reasonably provide it.

• A market participant may explain industry structure and purchasing behaviour.
• A customer with relevant experience may explain supplier selection and switching considerations.
• A former operator may explain historical processes within the limits of permitted discussion.
• Company documents may be needed to verify revenue, contracts, or financial performance.

This approach helps allocate expert calls to questions that human intelligence and experience can illuminate. It also keeps documentary verification with the appropriate source. Our guide to expert network calls in private equity explores how those conversations fit into the wider deal process.

Produce a screening note that supports a decision

A useful initial note answers five questions:

• What does the business do and where does it compete?
• Why might it fit the investment mandate?
• Which commercial assumptions currently support the case?
• What evidence could challenge those assumptions?
• What needs to be established before progressing?

Give the team enough information to advance, deprioritise, or commission further work. A well-defined uncertainty is more useful than a confident statement built on an unverified estimate.

Explore the company behind the opportunity

Third Bridge supports private-equity research with company intelligence and access to industry expertise. That combination can help teams move from a target name to a clearer understanding of the business and the questions worth pursuing.

Frequently asked questions

Where can investors find information on private companies?

Start with company websites, available registry filings, ownership announcements, relevant databases, and industry sources. Expert research can add context about markets and operating conditions. Verify the date, company perimeter, and evidence behind each source.

Can private company research replace a data room?

No. It can inform screening and prepare more focused diligence questions. Company financials, contracts, and other transaction documents remain necessary for the relevant verification work.

What if the target has limited existing research coverage?

Investigate its market, customers and competitors to establish context, while making clear where that evidence is indirect. A targeted expert brief can then address gaps that relevant industry experience may help resolve.
