Why the Best Private Market Deals Start with Primary Data

Discover why primary data is essential for private equity and M&A success. Learn how real-time expert interviews outperform outdated reports in due diligence and strategic decision-making.

In private equity and consulting, speed and certainty are key to success. Yet, too often, deal teams rely on secondary data, such as outdated reports, recycled benchmarks, or aggregated figures. In a world where markets shift overnight, yesterday’s numbers can leave you blind.  This is particularly true in private markets for analytics, where context expires quickly.


The reality is simple: in private markets, primary data, namely insights collected directly from current operators and decision-makers, is the only defensible source of truth. For teams considering how to evaluate private market data quality, direct conversations with current operators provide verifiable, source-of-truth inputs that outlast static reports.


The Data Hierarchy: Why Secondary Isn’t Enough 

Not all data carries the same weight. 

  • Secondary data: Public filings, analyst reports, and generic studies. Useful for context but often outdated before they are even published. 
  • Syndicated reports: Offer broad trends, but lack the granularity needed for deal-critical questions. 
  • Primary data: Direct conversations with industry participants, delivering insight into what is happening now, not last quarter. 
  • A 2024 Accenture report highlights that PE firms making faster, data-first decisions consistently outperform their peers.
  • Similarly, a Wolf & Co. study found that data-driven due diligence reduces surprises and accelerates value creation in portfolio companies.


Secondary sources may frame the picture, but only primary data fills in the details that matter — including the red flags that never surface in a data room until a qualified respondent names them directly, and the assumption ledger that gets tested before the deal closes. This hierarchy anchors effective private market data analysis, ensuring that conclusions reflect what operators are seeing now.


Real-Time Advantage in Private Markets 

Markets do not wait. Pricing shifts, competitors pivot, and regulations disrupt overnight. Firms anchored in last quarter’s data risk walking into deals with outdated assumptions. 


One Bell & Holmes client validated a looming supply chain disruption through a dozen targeted interviews in three days, weeks before it surfaced in the news cycle. That intelligence informed their investment thesis and helped avoid costly exposure. 


The point is clear: primary data is the only way to see around the corner.  Markets do not wait. Pricing shifts, competitors pivot, regulations move. Funds anchored in last quarter's data walk into deals with assumptions the market has already priced in.


One European PE client used Bell & Holmes to test a supply chain risk surfacing in a mid-market industrials target. Twelve targeted interviews with operations leads in three working days confirmed a disruption pattern that did not appear in trade press until the following month. The fund repriced before exclusivity expired.


A Big 3 consultancy ran a parallel pattern on a niche compliance software target serving hedge funds and asset managers across Europe and North America. Bell & Holmes completed 23 in-depth interviews with C-level executives and heads of compliance across the UK, US, Canada, France, Italy and the Netherlands in five working days. The findings reshaped the advisory recommendations going to the deal team and produced the post-engagement note that depth and quality landed at 5/5.

The Bell & Holmes Model 


Most primary research vendors fail one of three operational tests under deal pressure: they cannot start within 48 hours of brief, they cannot reach hard-to-access respondents in the time window available, or they cannot run multilingual outreach without losing precision in the conversation.


The infrastructure that solves all three at once is not common. It requires proprietary contact pools maintained before the brief arrives, research consultants trained to run cold outreach in their first language, and a quality assurance layer that confirms each respondent's role and purchasing scope independently of the source database.


Bell & Holmes built the model around that test. First results land within 48 hours of project kickoff. Coverage runs across 140+ countries and 35+ languages, with native-language consultants handling each market rather than translation intermediaries. Each project averages dozens of in-depth interviews - enough volume to build pattern recognition across respondent types, not just a small set of anecdotal calls. Retention sits at 98% across more than 1,000 completed engagements with PE firms, MBB consultancies and Big Four CDD teams.


The comparison that matters for a PE buyer: expert networks recruit opt-in members who chose to be available and price each call by the hour, which limits roster relevance to whoever signed up. Online B2B panels reach volume quickly but cannot guarantee role accuracy past the day of registration. Bell & Holmes sources by role and target firm for each project, then verifies the respondent during the interview itself - which is the data integrity bar an IC will actually challenge


Unlike surveys, which deliver numbers without context, or expert networks, which often lock you into costly, limited rosters, Bell & Holmes sits in the middle: fast, scalable, and deep. 


Statistics That Underscore the Shift 

  • According to Dakota, qualitative due diligence has become essential for PE investors, distinguishing between sustainable performance and one-off results.
  • Accenture found that PE firms using real-time, primary-sourced data make decisions faster and with greater confidence. 
  • CEPRES, which aggregates over $35 trillion in assets across more than 90,000 companies, notes that even advanced analytics rely on accurate primary inputs.

The consensus across the industry is that without fresh, operator-level insight, analytics and models are little more than educated guesses. 


Why Clients Choose Primary Data 

For private equity and consulting teams, the benefits are clear: 

  1. Certainty: Decisions backed by real conversations with the people shaping markets today. 
  2. Speed: Insights delivered in days, not weeks. 
  3. Coverage: Access to markets and operators beyond the reach of databases. 
  4. Confidence: Reduced risk of blind spots or reliance on outdated inputs. 

In time-critical due diligence, the cost of not having primary data is not just inefficiency: it is exposure.

At Bell & Holmes, we have built our approach on the principle that certainty comes from conversations, not assumptions. 


  • Dozens of interviews per project, designed to balance qualitative depth with quantitative confidence. 
  • Global reach: Interviews conducted in 140+ countries and 35+ languages, giving clients truly international perspective. 
  • Speed: First results in 48 hours, aligned with deal and strategy windows. 
  • Proven trust: Over 1,000 projects completed, a 98% retention rate, and consistent support for MBBs, Big Four, and top-tier PE firms. 


Private markets do not reward guesswork. They reward certainty, speed, and clarity. And those only come from primary research.

Article Q&A


Question: What is “primary data,” and how is it different from secondary or syndicated sources? 
Short answer: Primary data comes directly from current operators and decision-makers through real conversations, capturing what is happening now. In contrast, secondary data (filings, analyst reports, generic studies) and syndicated reports provide context but are often outdated or too high-level to answer deal-critical questions. In private markets, only primary inputs provide verifiable, source-of-truth insights that outlast static reports.

Question: Why does real-time primary data create an edge in private markets? 

Short answer: Markets move faster than publication cycles—pricing, competition, and regulation can shift overnight—so last quarter’s numbers create blind spots. Primary interviews surface emerging realities ahead of the news; for example, a Bell & Holmes client confirmed a looming supply chain disruption via a dozen targeted interviews in three days, shaping their thesis and avoiding exposure. Primary data is the only reliable way to “see around the corner.”
