An investment memo is the internal write-up that drives a firm's yes/no decision on a deal. It evaluates an investment opportunity comprehensively, connects the investment thesis to evidence, and gives investment committees the primary document they use to approve decisions.
Private equity, venture capital, growth equity, family offices, and corporate M&A teams all use memos. Formats change by business stage, but the goal stays the same: structured analysis for informed decisions, not a sales pitch.
FieldSignal supports this process with targeted expert interviews for due diligence, competitive landscape analysis, leadership assessment, and customer validation.

What Is an Investment Memo?
An investment memo is a structured document that summarizes a deal, the investment rationale, key findings from the diligence process, potential returns, and a recommendation for an investment committee or partners' meeting.
Investment memos synthesize market analysis and financial projections. They contain summaries of due diligence, risks, and potential returns, and help investors make informed decisions efficiently.
They're used across:
- Venture capital — for example a Series A SaaS company or seed-stage startup
- Private equity — for example a platform buyout or 2025 carve-out acquisition
- Corporate development — where strategic fit and integration costs matter
- Family offices and independent sponsors reviewing potential deals
Investment memos document due diligence for future reference, provide a time-stamped record of assumptions made when approving an investment, create a searchable archive of deal analysis, enhance accountability by documenting decisions, and help surface logical gaps in reasoning.
They aren't CIMs, pitch decks, or fundraising strategy documents. A good memo is balanced analysis, with dissenting views, risk factors, and mitigation strategies included.
Standard Investment Memo Structure (PE & VC)
- Executive Summary: One page with company name, sector, stage, revenue, valuation, check size, target ownership, recommendation, and top risks.
- Investment Thesis: Why this company, why now, why this price, and why the market opportunity supports the deal.
- Company Overview: Founding year, HQ, target company profile, product, customers, revenue model, and current stage.
- Market & Competitive Landscape: Market size, market landscape, competitive landscape, adoption drivers, and competitive analysis against direct and indirect competitors.
- Product & Business Model: Product workflow, pricing, retention, product-market fit, value proposition, and product roadmap.
- Financial Analysis: Historical performance, financial health, projections, cash flow, unit economics, IRR, MOIC, and valuation cases.
- Management Team: CEO, CFO, CTO, CRO, founders, governance, existing investors, and track record.
- Risk Factors: Market, competitive, product, execution, financial, regulatory, and key-person risks.
- Deal Terms: Security, ownership, liquidation preference, covenants, debt, and follow-on capital needs.
- Recommendation: Invest, pass, or further diligence, with data-driven conclusions.
Most firms use a fixed structure so partners compare potential deals across vintages. Memos typically range from 10 to 25 pages long. Concise memos are preferable and should limit to 2 to 4 pages for early screening or fast partner review.
Executive Summary & Investment Thesis
Busy partners often read this page first, then decide whether the rest deserves time.
Include:
- Company name, sector, stage, and round
- Revenue or ARR as of the latest quarter (e.g., Q1 2026)
- YoY growth, burn, EBITDA, or cash flow
- Proposed investment amount, valuation, ownership, and fund exposure
- Target returns (e.g., 3.0x MOIC and 20-25% IRR over 5-7 years)
- Decision requested: invest, pass, or further diligence
Write the investment thesis in 3 to 5 bullets:
- Why this particular startup or company wins
- Why the timing fits the investment landscape
- Why the price meets investor expectations
- Why the business model can scale
- Why the team can execute
A strong investment thesis connects company strengths to market opportunities. See our investment thesis guide for the deeper framework.
Company, Market, and Competitive Landscape
Open with facts. Don't start with adjectives.
Show:
- Founding year, HQ, legal entity, founders, and ownership
- Core product, target customers, and revenue model
- Business stage (Seed, Series B, growth equity, or platform buyout)
- Market size using TAM, SAM, and SOM with sources and dates
- Adoption drivers, customer pain, regulatory change, technology shifts from 2022 to 2026
- 5 to 10 named competitors, including incumbents and new entrants
| Area | What to show |
|---|---|
| Market | TAM, SAM, SOM, CAGR, source date |
| Buyers | Personas, budgets, switching triggers |
| Competitors | Direct, indirect, incumbent, new entrant |
| Differentiation | Pricing, product depth, customer experience |
| Expert input | Win/loss reasons, churn causes, switching behavior |
FieldSignal can source former executives, buyers, churned customers, suppliers, and channel partners to test whether the market story matches buyer reality.
Product, Business Model, and Traction
Describe what the customer does with the product. State which workflow it replaces and why customers pay.
Include:
- Pricing structure: subscription, usage-based, license plus maintenance, or services
- ACV, contract length, gross retention, net revenue retention, churn, and upsell paths
- Revenue or ARR progression from 2021 to 2025
- User counts, logo growth, cohort quality, and renewal behavior
- Key metrics that prove traction against peers
Good signals include rising retention, short payback, customer pull, and expansion revenue. Weak signals include flat cohorts, high churn, unclear buyer urgency, and product roadmap dependence.
For VC memos, product roadmap clarity matters. Venture capitalists want to know which 2026 to 2027 releases can change growth potential or unit economics.
Financial Analysis & Unit Economics
This is where private equity and growth equity teams spend the most time. VC uses lighter modeling, especially when a company has limited operating history.
Include:
- 2022 to 2024 actuals and latest 12 months
- Revenue, gross margin, operating expenses, EBITDA, burn, and cash flow
- 5-year financial projections, usually 2026 to 2030
- Bottoms-up drivers: sales headcount, conversion rates, pricing, churn, and expansion
- CAC, payback period, LTV/CAC, gross margin by product line, contribution margin, sales efficiency
Justify valuation with projections derived from comparable analysis. Show entry valuation, exit multiple, IRR, MOIC, and base/upside/downside cases.
Using data-driven storytelling is essential. Visuals like charts and graphs enhance the digestibility of memos.
Common return targets in PE and growth equity often center on 20-25% IRR and 2.5x-3.0x MOIC, though actual fund outcomes vary by vintage, sector, and exit market. Don't assume multiple expansion. Over-optimistic projections can mislead investors.
Management Team, Governance, and References
The management team section should prove execution capacity, not list biographies.
| Field | What to include |
|---|---|
| Name | CEO, CFO, CTO, CRO, COO |
| Role | Current responsibility |
| Background | Prior companies, exits, P&L size |
| Strengths | Hiring, sales, product, operations |
| Concerns | Gaps, references, key-person risk |
Look for a proven track record since 2010 — scaling from Series A to IPO, managing a large P&L, or operating through a downturn. Existing investors and board members also matter if they improve follow-on capital access or governance quality.
Summarize reference checks. Include expert views on leadership style, domain knowledge, hiring ability, and operating discipline. FieldSignal supports leadership assessment through vetted former employee and customer interviews.
Risk Factors, Mitigation, and Bear Case
Strong memos in 2024 to 2026 treat risk factors as central content.
| Risk type | Example | Mitigation |
|---|---|---|
| Market | Adoption slows after 2025 | Validate buyer urgency through calls |
| Competitive | New entrant cuts price | Test win/loss data |
| Product | Roadmap slips | Tie funding to milestones |
| Execution | Sales hiring misses plan | Review hiring funnel |
| Financial | Margin erosion | Stress test CAC and pricing |
| Regulatory | Rule change affects demand | Interview compliance experts |
| Key-person | CEO dependency | Assess bench strength |
Insufficient risk analysis often leads to poor investment decisions. Failing to provide balanced analysis is a frequent error.
Write a bear case as a real scenario: growth slows, pricing compresses, churn rises, and the exit multiple falls. Include probability, impact, and mitigation. The memo should demonstrate deep due diligence and preparedness for follow-up questions.
Deal Terms, Structure, and Exit Paths
- State security type: preferred equity, common equity, debt, convertible note, or structured equity
- Include valuation, ownership percentage, liquidation preference, anti-dilution terms, pro rata rights, and board rights
- For PE, show equity vs debt mix, leverage ratios, covenants, seller notes, earn-outs, and cash flow coverage
- Summarize syndicate composition: co-investors, other investors, reputation, follow-on capital capacity
- List exit paths: strategic sale, sponsor-to-sponsor sale, or IPO
- Name likely buyer categories and timing assumptions
- End with how the structure aligns management, existing shareholders, and new investors
How Investment Memos Differ Across Fund Types
| Fund type | Most space goes to | Less space goes to |
|---|---|---|
| Early-stage venture capital | Team, market size, product vision | Detailed financial analysis |
| Growth equity | Revenue quality, retention, path to profit | Pure vision |
| Buyout PE | Cash flow, debt capacity, downside protection | Early product theory |
| Corporate development | Strategic fit, integration costs, operating impact | IRR and MOIC alone |
Seed rounds may use fewer than 10 pages. Large buyouts can exceed 30 pages with appendices. VC firms underwrite uncertainty differently than buyout investors.

Using Expert Networks to Strengthen Your Memo
Expert interviews test the claims that desk research can't prove. They validate or challenge assumptions about market size, pricing power, management quality, customer pain, and competitive position.
FieldSignal uses pay-per-use pricing, no annual retainer, no minimum commitment, and pass-through call costs with no markup on expert honoraria. That contrasts with opaque, retainer-heavy models often associated with GLG, AlphaSights, Third Bridge, Guidepoint, Tegus, AlphaSense, Capvision, ProSapient, Coleman Research, Atheneum, Mosaic Research Management, and Inex One.
Use experts in:
- Market: buyers confirm budget, urgency, and adoption barriers
- Competitive: churned customers explain why vendors lose
- Management: former employees assess execution quality
- Risk: operators test regulatory, technical, and financial assumptions
Example scenarios:
- A customer call shows pricing power is weaker than the model assumes
- A former competitor explains why the target wins mid-market accounts
- An ex-employee identifies a sales leadership gap before IC approval
See our pre-investment research workflow for the upstream view.
Workflow: From Diligence Notes to Finished Memo
- Capture initial call notes, including claims, metrics, and unanswered questions
- Run desk research on market, company, competitors, and valuation comps
- Schedule expert and customer calls through FieldSignal for diligence
- Build the financial model with historicals, projections, unit economics, and sensitivities
- Draft the investment thesis and assumption log
- Write the first memo draft with charts, tables, and short commentary
- Collect partner feedback and note dissent
- Finalize the IC-ready memo and presentation
Keep an assumption log during the due diligence process. Convert it into risks, bear case items, and follow-up questions.
Recommendation Page, IC Discussion, and Post-Mortems
The final page should be direct. Don't bury the answer.
Include:
- Recommendation: invest, pass, or further diligence
- Proposed investment size and ownership
- Conditions precedent
- Remaining diligence items, owner, and deadline
- "How we'll know we were wrong" indicators
- Final rationale tied to data
Firms often revisit memos 2 to 5 years later to review winners and losses. The memo becomes evidence of what investors believed, what risks they accepted, and how well the firm made investment decisions.
Start Structuring Better Investment Memos
A disciplined investment memo improves decision making because it forces the team to connect facts, assumptions, risks, and returns.
- Strong memos combine quantitative financial analysis with qualitative expert guidance
- Strong memos reduce bias by providing balanced analysis and naming potential risks
- Strong memos create a usable record for future track record reviews
