Pre-investment research is the structured work you do before committing to a full due diligence process. It tells you whether a deal is worth your time, your fund's capital, and the legal and consulting fees that come with formal diligence. This article walks through the exact workflow PE and VC associates use to evaluate investment opportunities before a single term sheet goes out.
What Pre-Investment Research Is and Why It Matters
Pre-investment research sits between "we saw the deck" and "we're in full DD." Its mission is to test your investment thesis, price risk, and determine whether a deal deserves the resources of formal investment due diligence. You're working with lighter data rooms or none at all, leaning on external signals, hypothesis-driven interviews, public comps, and desk research.
For PE and VC associates, this matters because it shortens IC memos, kills dead deals faster, and improves win rates. In both private market and pre-IPO situations, the company selling you on the deal controls the narrative. Your job is to verify it before your fund writes a check.
How it differs from full diligence: formal investment due diligence is inside-out. You're in the VDR, reviewing every income statement, every customer contract, running Quality of Earnings. Pre-investment research is outside-in. You're triangulating from experts, customers, public filings, and market data.
The 2024 to 2026 context makes this critical. PE buyout holding periods hit roughly 7.1 years in 2023, the longest in two decades. The median time to IPO has doubled to approximately 14 years. Private market liquidity increased with over $2.1B transacted in 2025. Global PE fundraising fell roughly 24% in 2024. Effective pre-investment research minimizes risks and aligns investments with financial goals.
FieldSignal fits this early stage. It's a pay-per-use expert research partner you can engage before you commit to bankers, QoE providers, or large consulting budgets. No retainer, no minimum spend.
Step 1: Frame the Investment Thesis and Kill Criteria
Before you research anything, write down what you believe and what would kill the deal.
- Draft a 1-2 page thesis document. Cover the target vertical, your fund's AUM constraints, deal size range, intended hold period, and return profile for the current vintage.
- Convert that into 3-5 explicit thesis statements. Example: "Mid-market managed security services will grow 12-15% CAGR through 2030 due to compliance and ransomware pressure."
- Define 4-6 kill criteria up front. Customer churn above 20%. CAC payback over 30 months. Regulatory overhang. Founder reputation concerns. Unverified pipeline claims.
Defining specific investment goals aligns financial strategies and keeps you from chasing deals that don't fit. Risk mitigation at this stage helps avoid significant capital losses later.
| Thesis | Testable Question | Data Source |
|---|---|---|
| MDR will grow 12-15% CAGR through 2030 | What's the current growth of demand among mid-market buyers? | Expert interviews with CISOs, Gartner/Forrester reports |
| Customer churn in target SaaS stays under 10% | What's typical churn for ARR $10-50M companies in this sector? | Public comps, customer interviews, benchmark reports |
| Compliance regulation will accelerate adoption | What proposals are active in target markets? | Government filings, regulatory expert calls |
Step 2: Market Sizing and Structure
Market sizing for private companies isn't clean. You won't get perfect disclosures. You'll triangulate from multiple sources, and you'll accept ranges instead of precise numbers.
Break your work into TAM, SAM, and SOM. Use real data, not generic theory. Pre-IPO cybersecurity vendors raised US$2.07 billion in Q4 2024 alone, and 77% of total funding in 2024 went to US-based vendors. Since 2020, 62 pre-IPO cybersecurity vendors secured over $300 million each. See market sizing guide for the broader framework.
Analyzing financial health involves reviewing balance sheets and income statements. For private companies, you'll often estimate these from sample data, funding round disclosures, and expert interviews rather than full financials.
- Public market signals: KPIs, valuation multiples, revenue growth, retention rates from comparable public companies. EV/Revenue multiples in many segments dropped roughly by half since 2021 peaks.
- Private market signals: Funding round sizes, secondary pricing, tender offers, SPV structures. The average trading discount for pre-IPO shares shrank to 8% in Q1 2026, down from roughly 49% in early 2024.
- How to use in pre-investment research: Cross-reference public comps with private signals. If public comps show margin compression but the target claims expanding margins, that's a question for expert calls.
Step 3: Competitive and Customer Reality Checks
This is where you test the story you heard from the deck against what the market actually says.
Three priority workstreams:
- Competitive intelligence. Build a one-page grid of 5-10 direct and adjacent competitors. Include pricing bands, channel strategies, and 2023-2025 funding events. Use public filings, news, and expert calls to former executives.
- Customer voice. Run 5-15 customer interviews or surveys. Quantify NPS, churn drivers, switching behavior, and willingness to pay. In pre-IPO situations, official metrics are curated. Talk to actual buyers.
- Product and roadmap validation. Talk to product leaders, ex-employees, channel partners. Check if claimed features exist in production. Look for "deck drift," where the prospectus tells one story but execution tells another.
Evaluating the intrinsic value of an asset is essential before investing, and identifying fair value through customer and competitor checks helps prevent overpaying.
This is where FieldSignal fits best. You need ex-customers, former sales leaders, and channel partners sourced quickly. FieldSignal connects you with these profiles on a per-project basis so you can see if the logo slide and pipeline claims match reality.
Step 4: Early Investment Due Diligence vs Full DD
Early due diligence is mostly outside-in. You're not in a VDR yet. You're running expert interviews, reference calls, light financial modeling, and legal red-flag scans. Full diligence comes later with QoE, 200-page commercial DD reports, and inside-out financial scrubs.
What an associate can own in weeks 1-4:
- 6-12 expert interviews with operators, customers, and competitors in the space
- A lightweight cohort analysis using sample data from the company or plan estimates
- Early churn and NRR estimates benchmarked against public comps
- A 3-scenario revenue model (base, upside, downside)
For pre-IPO and late-stage private market deals, early DD also means checking secondary pricing history and recent tender offers. In 2024, 18 biotech IPOs occurred, up from 10 in 2023, signaling that some sectors see improving exit windows. Meanwhile, 34% of secondary trades executed at a premium in Q1 2026, and the average trading discount for secondary trades is now 8%.
FieldSignal is structured for this phase. Per-project pricing, transcript libraries, and compliance guardrails comparable to GLG, AlphaSights, and Third Bridge, but without opaque retainers or annual minimums. See our deal sourcing guide for the upstream view.
Step 5: Building a Pre-IC Memo from Your Research
The goal is a 5-10 page pre-IC deck that lets partners decide whether to commit to full diligence.
Recommended memo sections:
- Deal overview: company, sector, stage, ask, valuation, ownership structure
- Thesis and kill criteria
- Market and competitive summary with comps
- Customer and expert insights, with sourced quotes
- Key risks and open questions
- Proposed work plan for full DD
When quoting expert calls, preserve anonymity but make findings concrete. Example: "Former VP Sales at top-3 competitor, Jan 2026 call: 'Their mid-market pipeline is real, but enterprise deals close 2x slower than their deck shows.'" This gives IC members confidence without exposing sources.
Many funds now include a "private market signals" page. Show the last three primary rounds, any known secondaries, and pre-IPO or SPV pricing from 2023-2026. Reference any unusual preferences or structure.
Practical tips:
- Timebox pre-investment research to 3-4 weeks.
- Lock the IC date before you start, so deliverables have a deadline.
- Treat every expert call transcript as an asset you can reuse across deals.
- Document all references clearly: expert calls, surveys, funding data, public comps.
Using Expert Networks for Pre-Investment Research
Expert interviews are now a default part of pre-investment research. Even seed and Series A checks rely on them. Associate time is usually the bottleneck, not budget.
Traditional networks like GLG, AlphaSights, Third Bridge, Guidepoint, Tegus, AlphaSense, Capvision, ProSapient, Coleman Research, Atheneum, Mosaic Research Management, and Inex One typically serve large funds with opaque retainers, annual minimums, and internal approval cycles. Senior expert calls often run $1,200-$1,500/hr through these networks. That pricing model works for billion-dollar hedge funds. It doesn't work for most people at mid-market firms.
| Criterion | Traditional Expert Network | Marketplace Alternatives | FieldSignal |
|---|---|---|---|
| Pricing | Annual retainers, hidden markups, minimums | Project-based, quality varies | Pay-per-use, pass-through honoraria, no retainer |
| Compliance | Strong but slow approvals | Lighter controls, higher MNPI risk | Equivalent to large networks, faster process |
| Fit for sub-$50k projects | Often exceeds budget floor | Possible, but expert quality inconsistent | Built for this segment. No minimums. |
| Expert sourcing speed | Fast for common profiles | Variable | Common profiles in 24-72 hours |
| Winner for mid-market PE/VC | No | No | Yes |
FieldSignal's positioning is specific: B2B, pay-per-use expert research with pass-through expert honoraria, no annual retainer, and compliance processes aligned with large networks. Smaller funds, corporate strategy teams, and clients running boutique consulting engagements get the same guardrails without six-figure contracts.
How a typical FieldSignal pre-investment project runs:
- Scope a question set and target expert profiles in 24-48 hours
- Book 5-15 calls or surveys within a week
- Receive transcripts plus a short synthesized readout you can plug directly into your pre-IC deck
The Takeaway and Next Step
- Structured pre-investment research reduces wasted DD spend, sharpens IC conversations, and helps you price risk correctly in private market and pre-IPO deals.
- The workflow in one line: define thesis and kill criteria, size the market, test competitor and customer reality, run early investment due diligence, and package findings for IC.
- Using an expert network partner like FieldSignal on a pay-per-use basis lets you run this process on more deals, across more sectors, without committing to GLG or AlphaSights-style retainers.
