If you're a consultant competing for commercial due diligence mandates from PE clients, you already know the landscape has shifted. Bain's 2026 Global PE Report puts it bluntly: "12 is the new 5." Today's deals demand faster EBITDA growth. GPs have to generate more cashflow and up their value creation game to make deals work. The era of cheap debt and easy multiple expansion is over.
What does that mean for you? PE firms are no longer satisfied with a CDD report that tells them the market is growing at 7% and the target has a decent competitive position. They want full potential diligence — a holistic, multidisciplinary assessment that identifies the revenue levers, operational levers, and technology levers that will produce a real step change in performance. They want a Day 1 value creation plan anchored in evidence, not assumptions.
The demand is real. Buyout deal value rose 44% to $904 billion in 2025. Exit value climbed 47% to $717 billion. The mid-market ($1B–$5B segment) grew 29% year over year. And with 32,000 unsold companies worth $3.8 trillion sitting in PE portfolios, sell-side CDD and vendor due diligence are surging too.
But here's the part that matters most for consulting teams: the quality of your primary research programme is increasingly what separates winning a mandate from losing it. Investment committee members can tell the difference between a CDD backed by five generic expert calls and one backed by 25 targeted interviews with customers, competitors, and industry specialists. PE firms are quietly assessing CDD firms on exactly this dimension.
This guide is for engagement managers and consultants at strategy firms — particularly lean, mid-market teams — who want to win more CDD mandates and deliver higher-quality work. It covers how to scope an expert programme, when to use a self-service expert network versus a done-for-you research provider, and how to turn primary research into the kind of investment-grade insight PE clients actually pay for.
What PE Clients Actually Expect from CDD in 2026
Let's dispense with the basics. You know what CDD is: an independent assessment of a target's market, customers, competitors, and growth outlook conducted on behalf of a PE buyer (bid-side) or seller (vendor due diligence). You've done these before.
What's changed is the bar. Here's what PE clients expect now that they didn't five years ago:
From market sizing to full potential diligence
The old CDD deliverable was a market overview, competitive landscape, customer analysis, and a "base case" growth estimate. The new standard — what Bain calls full potential diligence — requires you to identify specific, executable value creation levers. Revenue levers (pricing power, cross-sell, geographic expansion). Operational levers (margin improvement, procurement, automation). Technology levers (AI, digital transformation, product modernisation). Your CDD report needs to feed directly into a post-acquisition value creation plan.
Primary research as the backbone, not a supplement
Expert networks have become central to due diligence work. The experts they supply provide deep content insights, especially for forward-looking perspectives — estimating future revenues, assessing competitive threats, validating customer sentiment. A CDD report built primarily on secondary research and desk analysis no longer cuts it. PE clients expect to see a rigorous primary research programme underpinning your conclusions: who you spoke to, how many, what they said, and how you triangulated their input.
Speed without sacrificing depth
A typical CDD engagement runs 2–4 weeks — sometimes up to 6 within an exclusivity window. That's a fraction of a standard strategy engagement. PE clients expect the same analytical depth in a third of the time. This is where most consulting teams feel the squeeze hardest.
Defensible conclusions, not opinions
Investment committees scrutinise CDD findings. Every claim about market growth, competitive positioning, or customer retention needs to be traceable to specific evidence — expert interviews, survey data, customer references, or quantitative analysis. "We believe the market is attractive" backed by two analyst reports doesn't hold up.
The Primary Research Gap: Why Most CDD Falls Short
Here's a contrarian take: most CDD reports are mediocre because the primary research was mediocre. The prevailing model relies too heavily on secondary data and too little on rigorous expert programmes. And when primary research is attempted, it's often poorly scoped, rushed, or under-resourced.
These are the failure modes we see most often:
Starting primary research too late
Too many teams spend the first week on desk research and data analysis, only beginning expert outreach in week two. By then, half the project timeline is gone, and the expert programme is compressed into a frantic scramble that yields thin, poorly sequenced insights.
Under-scoping the expert programme
Five or six expert calls is not a primary research programme — it's anecdotal evidence. A defensible CDD typically requires 10–30 expert interviews across customer interviews, competitor interviews, industry experts, and former employees of the target. The mix matters as much as the volume.
Generic discussion guides
The discussion guide is the most important document in your expert programme. If your questions don't map directly to the PE client's key investment hypotheses — market growth drivers, competitive moats, customer switching costs, pricing dynamics, regulatory risk — you'll generate transcripts full of interesting-but-irrelevant commentary.
The synthesis bottleneck
This is the most underestimated problem. Raw transcripts from 15–30 expert calls require significant analytical effort to synthesise into coherent, investment-grade findings. On a lean team of 3–5 people, the synthesis work can overwhelm the entire project if it isn't planned for from the start.
Failing to triangulate
Expert opinions are supplementary evidence, not authoritative conclusions. The best CDD teams triangulate expert insights with quantitative data, customer survey results, and internal analysis. When you rely on any single source — including experts — you're building your conclusions on shaky ground.
Managing expert logistics instead of doing analysis
Here's the uncomfortable truth: every hour a consultant spends scheduling calls, chasing experts, and managing network logistics is an hour not spent on the analytical work the PE client is actually paying for. On a typical CDD, consultants activate 3–4 expert networks simultaneously. The administrative overhead is enormous. And yet most project plans treat it as a minor line item.
How Expert Networks Work for CDD
If you're already using expert networks, you can skim this section. If you're building or formalising your approach, here's the anatomy of a CDD expert programme.
The expert network landscape
The expert network market hit approximately $3 billion in 2025, growing around 12% annually. Over 120 expert networks now operate worldwide, up from 38 in 2009. The consulting sector remains the largest segment, accounting for almost half of total industry spend.
Major players include GLG (roughly 50% share of client usage), AlphaSights (known for speed), Third Bridge (combines expert calls with an analyst-led interview library), Guidepoint, Dialectica, and marketplace platforms like Inex One.
Types of experts in a CDD programme
A well-designed CDD expert programme typically includes four expert categories:
- Customer interviews: Current and former customers of the target company. These validate revenue quality, satisfaction, switching likelihood, and willingness to pay. Often the most valuable category.
- Competitor interviews: Executives at competing firms who can speak to market dynamics, the target's perceived strengths and weaknesses, and competitive threats.
- Industry experts: Analysts, advisors, trade association leaders, and consultants with broad market knowledge. Good for market sizing validation and trend identification.
- Former employees of the target: People who have worked at the target company and can speak to operations, culture, technology, and internal challenges. Handle with care — compliance considerations apply.
How many calls?
There's no universal answer, but here are practical benchmarks:
- Minimum viable programme: 10–12 calls. Enough to identify patterns but thin on any single expert category.
- Standard programme: 15–20 calls. Sufficient for most mid-market CDD engagements with a focused scope.
- Comprehensive programme: 25–30+ calls. Required for complex deals, multi-geography targets, or engagements where primary research is the primary differentiator in your deliverable.
Self-service vs. done-for-you: two fundamentally different models
This distinction is critical and often misunderstood. There are two models for getting primary research done:
Self-service expert networks (GLG, AlphaSights, Guidepoint, etc.) give you access to their expert database. You tell them what profiles you need. They recruit and schedule the experts. You write the discussion guide, conduct the interviews yourself, and synthesise the findings. The network charges per call — typically $1,000–$2,000+ per hour-long consultation.
Done-for-you primary research providers (like Woozle Research) handle the entire workflow. You brief them on the deal thesis, the target, and the key questions. They recruit and screen experts, write discussion guides, conduct the interviews, and deliver synthesised findings. You focus on analysis, client communication, and building the final deliverable.
The difference isn't just convenience — it's a fundamentally different allocation of your team's time and cognitive bandwidth. We'll dig deeper into when each model fits in a dedicated section below.
Building the Expert Programme: A Step-by-Step Framework
This is the most actionable section of the guide. Here's how to scope, design, execute, and synthesise a CDD expert programme — from mandate kick-off to final deliverable.
Step 1: Define key investment questions (Day 1–2)
Before you touch an expert network, sit down with the PE client (or review the information memorandum thoroughly) and distil 5–8 key investment questions. These should map directly to the deal thesis. Examples:
- Is the target's core market growing at the rate the management case assumes? What are the drivers and risks?
- How durable is the target's competitive moat? What would it take for a competitor to displace them?
- How satisfied are the target's customers? What's the real switching cost?
- What pricing power does the target have? Is there room to increase prices post-acquisition?
- What are the realistic organic growth levers beyond the base case?
- Are there regulatory, technological, or market risks the management team is underweighting?
Every subsequent decision — expert profiles, discussion guide questions, interview sequencing — flows from these investment questions.
Step 2: Design expert profiles (Day 2–3)
For each investment question, identify which expert types can provide the most useful input. Be specific about profiles: not just "industry expert" but "VP of Procurement at a top-5 customer of the target in the DACH region" or "Former Regional Sales Director at the target's main competitor, departed within the last 18 months."
Map your expert needs against the four categories (customers, competitors, industry, former employees) and assign a target number of calls to each. A typical split for a 20-call programme might be: 6–8 customer interviews, 4–5 competitor interviews, 4–5 industry experts, 3–4 former employees.
Step 3: Write the discussion guide (Day 2–4)
Your discussion guide is not a survey questionnaire. It's a structured conversation framework — typically 15–25 questions organised by topic area, with probing follow-ups for each. Best practices:
- Start broad, then narrow. Open with the expert's background and market perspective. Move to competitive dynamics. Close with target-specific questions and forward-looking views.
- Map every question to an investment question. If a question doesn't help answer one of your 5–8 key questions, cut it.
- Include "hypothesis-testing" questions. Don't just ask "Is the market growing?" Ask "Management projects 15% growth over the next three years driven by X and Y. Based on your experience, is that realistic? What could cause it to be higher or lower?"
- Tailor by expert type. Your customer discussion guide should differ from your competitor guide. You may need 3–4 variants.
- Leave room for unexpected insights. The best expert calls surface things you didn't think to ask about. Build in open-ended questions: "What's the one thing about this market/company that outsiders typically misunderstand?"
Step 4: Activate the research (Day 3–5)
This is where the self-service vs. done-for-you decision matters most. If you're running the programme yourself using self-service networks, you'll need to:
- Brief 3–4 expert networks simultaneously (management consultants engage an average of 3 networks per project)
- Review expert profiles as they come in and approve/reject
- Coordinate scheduling across time zones
- Prepare for and conduct each call (45–60 minutes each, plus prep and note-taking time)
If you're using a done-for-you provider like Woozle, you brief the team on the deal thesis, target, and key questions. They handle expert recruitment, screening, scheduling, discussion guide refinement, interview execution, and initial synthesis. Your team gets delivered findings, not logistics.
Step 5: Sequence your interviews strategically (Week 1–3)
Don't treat all expert calls as equal. Sequence them:
- Industry experts first (week 1): Build your baseline understanding of market dynamics, competitive landscape, and industry trends. Use these calls to refine your hypotheses and sharpen your discussion guides for later calls.
- Competitor interviews second (week 1–2): Understand the competitive landscape from the inside. Identify what competitors think of the target, where they see vulnerability, and where they see strength.
- Customer interviews third (week 2–3): Armed with market context and competitive intelligence, you can ask sharper, more targeted questions of the target's customers.
- Former employees last (week 2–3): These are your "insider" calls. Use them to validate or challenge what you've heard from external sources.
Step 6: Synthesise and triangulate (Week 3–4)
This is where the real value is created — and where most consultants underinvest. Synthesis is not summarising transcripts. It's identifying patterns, contradictions, and implications across your entire evidence base.
A practical synthesis framework:
- For each key investment question, create a summary that includes: what the experts said (with direct quotes where compelling), what the quantitative data shows, where the evidence converges, and where it conflicts.
- Flag consensus and disagreement. When 8 out of 10 experts say the same thing, that's a strong signal. When experts disagree, the disagreement itself is valuable — it identifies areas of genuine uncertainty the PE client needs to understand.
- Link findings to value creation levers. Don't just describe the market — tell the PE client what actions they could take post-acquisition based on what the research revealed.
- Be explicit about confidence levels. "We have high confidence in X based on converging evidence from 12 expert interviews and three independent data sources. We have moderate confidence in Y, which is supported by expert opinion but lacks quantitative corroboration."
Self-Service vs. Done-for-You: Which Model Fits Your Team?
This is the decision most consulting teams don't think about carefully enough. They default to self-service expert networks because that's what they've always used. But the two models serve fundamentally different needs.
When self-service makes sense
- Your team has dedicated research capacity. You have analysts or associates whose primary role on the CDD is conducting expert interviews. They have the bandwidth, and doing the calls themselves helps them build pattern recognition.
- You need very specific, niche experts. When the expert profile is highly unusual (e.g., one of four people globally who has run a specific type of facility), you may want to directly manage the recruitment and conversation.
- The engagement scope is narrow. If you only need 3–5 calls on a tightly defined topic, the overhead of briefing a done-for-you provider may not be worth it.
- Budget is unconstrained. Self-service expert networks charge $1,000–$2,000+ per consultation. For a 20-call programme, that's $20,000–$40,000+ in expert network fees alone, before accounting for the consultant time spent managing the process. If your project budget easily absorbs this, fine.
When done-for-you makes sense
- Your team is lean. If your CDD team is 3–5 people (typical for mid-market engagements), every hour spent on research logistics is an hour stolen from analysis. A done-for-you provider like Woozle absorbs the entire research operations burden.
- The expert programme is large or complex. 15–30 calls across multiple geographies, expert types, and discussion guides — this is a project within a project. Done-for-you providers are built to manage this complexity.
- Speed is critical. When you need 20 expert interviews completed in 2–3 weeks, a dedicated research team running the programme full-time will outpace a consulting team juggling research alongside analysis, client communication, and deliverable production.
- You want to compete on primary research quality. Done-for-you providers like Woozle deliver synthesised findings, not raw transcripts. The output is designed to slot directly into your CDD deliverable. This lets lean teams deliver primary research at a quality level that rivals what MBB firms produce with their 200-person internal research teams.
- You need to protect margins. CDD engagements are typically fixed-fee. With a done-for-you provider, you get a predictable research cost (no per-call pricing surprises) and free your consultants to focus on the billable analytical work that drives project quality.
The hidden cost of self-service
Here's what most project plans underestimate: the fully loaded cost of running a self-service expert programme on a CDD. For a 20-call programme, a consultant or senior associate will spend approximately:
- 4–6 hours briefing networks and reviewing expert profiles
- 3–4 hours on scheduling and logistics
- 20–25 hours conducting calls (including prep)
- 10–15 hours on note-taking and initial synthesis
That's 37–50 hours of consultant time — essentially an entire week of a senior team member's capacity on a 3–4 week project. At consulting billing rates, the implicit cost is far higher than most teams realise. Self-service expert networks can create more work, not less, for consultants.
Winning the Mandate: How Primary Research Differentiates Your CDD Proposal
If you're a boutique or mid-market consulting firm competing against Bain, L.E.K., or EY-Parthenon for CDD mandates, you face an obvious challenge: PE clients know those firms have massive research infrastructure. They know Bain claims to be the largest and most sophisticated user of primary research globally. How do you compete?
The answer is to make your primary research approach the centrepiece of your proposal — not an afterthought.
What to include in your CDD proposal
- A detailed primary research plan. Specify the number of expert interviews, the expert profile categories, the survey methodology (if applicable), and the timeline. "We will conduct 20–25 expert interviews across four categories: 8 customer interviews, 5 competitor interviews, 5 industry experts, and 4 former employees of the target" is far more compelling than "We will supplement our analysis with expert interviews."
- Your research infrastructure. Name your research partner. Explain the model. If you work with a done-for-you provider like Woozle, say so: "Our primary research is powered by a dedicated research partner that handles expert recruitment, screening, and interview execution, allowing our consulting team to focus entirely on analysis and synthesis." This directly addresses the PE client's unspoken concern: "Can this small team actually deliver the research depth we need?"
- Your synthesis methodology. Explain how you turn 20 expert conversations into investment-grade conclusions. Show the PE client that you have a structured framework for triangulating expert insights with quantitative data — not just a pile of transcripts.
- Your timeline with research milestones. Show that expert outreach starts in the first 48 hours. Show when preliminary findings will be available for a mid-project checkpoint. Show when synthesis is complete. This signals experience and project control.
Pricing expert costs into fixed-fee proposals
This is a practical challenge that trips up many consulting teams. Expert network costs — whether self-service or done-for-you — need to be embedded in your project fee. A few principles:
- Don't treat research costs as pass-through. PE clients are buying a fixed-fee CDD engagement. They don't want line-item invoices for individual expert calls. Build the research cost into your total fee.
- Budget 15–25% of the total project fee for primary research. On a $150K CDD engagement, that's $22K–$37K for expert costs. This is realistic for a well-scoped programme using a done-for-you provider.
- Scope the programme before you price. The number of expert interviews and geographies drives the research cost. Don't guess — scope it during the proposal process and price accordingly.
AI, Technology, and the Future of CDD Research
AI is transforming the CDD workflow — but not in the ways most people assume. Here's what's changing and what isn't.
What AI is already doing
- Transcript analysis: AI tools can process expert call transcripts and surface patterns, contradictions, and key themes across 20+ interviews in minutes rather than hours. BCG's enterprise GPT platform reportedly reduces complex analysis time from two weeks to three days.
- Discussion guide generation: AI can produce first drafts of discussion guides based on deal briefs, sector context, and standard CDD frameworks. A good consultant still needs to refine them — but the starting point is dramatically better than a blank page.
- Secondary research acceleration: Market sizing, competitive mapping, and regulatory scanning are all faster with AI-assisted desk research.
- Expert matching: Some expert networks are using AI-powered matching to improve the speed and accuracy of expert recruitment.
What AI is not replacing
- The expert conversations themselves. A skilled interviewer adapts in real time, follows unexpected threads, and probes beneath the surface. AI cannot replicate the judgment, rapport, and instinct that makes a great expert interview productive.
- Strategic synthesis. AI can identify patterns in transcripts. It cannot tell you what those patterns mean for a $500M acquisition decision. The "so what" — linking primary research findings to investment conclusions and value creation levers — remains fundamentally human work.
- Relationship-based expert recruitment. Finding the right expert for a niche CDD question — a former customer of the target in a specific region, a competitor executive willing to share candid views — requires human networks, judgment, and persistence.
The near-term outlook
Over the next 12–24 months, expect AI to further compress CDD timelines and raise the quality floor for desk research and transcript processing. But the firms that win mandates will be those that combine AI-augmented efficiency with superior primary research — more expert interviews, better expert profiles, sharper discussion guides, and deeper synthesis. The technology accelerates the workflow. It doesn't replace the insight.
The scope of CDD itself is also expanding. Leading firms like EY-Parthenon now offer AI, IT, product and technology, sustainability, and cyber due diligence alongside traditional commercial assessment. As CDD broadens, the demand for specialised primary research across these domains will only increase.
Putting It All Together: The CDD Research Playbook
Here's what "good" looks like when a consulting team gets the primary research right:
- 20+ expert interviews, triangulated with quantitative market data and customer survey results
- Clear investment thesis validation — or challenge — with traceable evidence from primary sources
- Specific, actionable value creation levers identified and linked to expert findings
- Full CDD report delivered within 3–4 weeks of mandate start
- A Day 1 value creation plan anchored in what the research actually revealed, not what the management team claimed
The consulting teams that consistently deliver this level of CDD are the ones PE firms come back to. In an industry where sentiment is cautious and half of consultants are bearish on the next 12 months, building a reputation for PE-grade diligence backed by rigorous primary research is the clearest path to sustainable deal flow.
The consultant's value-add is in synthesis and judgment, not in scheduling calls. If you're spending your project bandwidth on research logistics instead of the analytical work your PE client is paying for, something in your operating model needs to change.
How Woozle Fits
Woozle Research is a done-for-you primary research provider. We're not an expert network — we don't sell access to experts or charge per call.
