How to Write an Investment Memo (VC Template and Examples)

Every VC investment starts with a memo. It's the document that makes the case — or kills the deal. And yet, most investment memos are terrible. They read like marketing brochures for the company instead of rigorous analyses of an investment opportunity. The best memos are honest, specific, and structured to help partners make a decision in under 15 minutes.

Whether you're a junior VC writing your first memo, a founder preparing for diligence, or an aspiring investor building your skills, understanding the investment memo is non-negotiable. Here's the complete template, section by section, with examples of what separates good from forgettable.

What an Investment Memo Actually Is

An investment memo is an internal document written by a deal team member recommending for or against a specific investment. It's not a pitch deck summary. It's not a company profile. It's an argument — backed by evidence — about whether this company is worth the firm's capital. The audience is the partnership, and they're reading it to make a bet worth millions.

Memo length scales with check size. For a seed investment ($500K–$2M), expect 3–5 pages. For a Series A ($5M–$15M), 8–12 pages. For a Series B+ ($20M+), 12–15 pages with appendices. Some firms like memos longer; some (like early Benchmark) famously kept them short. Know your firm's culture.

Section 1: Executive Summary

One paragraph. Three to five sentences. This is the most important part of your memo because it's the only part every partner will read in full. State the company name, what they do, the proposed investment amount and terms, and your recommendation. Be direct.

Bad: "Acme is an exciting company in a large market with a strong team." Good: "Acme automates invoice reconciliation for mid-market CFOs, replacing a manual process that costs companies $200K+/year in labor. They have $2.1M ARR growing 3x YoY with 140% net retention. I recommend we lead their $8M Series A at a $32M pre-money valuation."

Section 2: Company Overview

What does the company do? Who are the customers? What problem does it solve? How does it make money? Keep this factual and concise — one to two paragraphs. Include founding date, location, headcount, and total funding to date. This section establishes context; it shouldn't be where you spend your writing energy.

Section 3: Market Opportunity

This is where most memos fall apart. They cite a Gartner report saying the TAM is $50 billion and move on. That tells the partnership nothing. A good market section includes TAM (total addressable market), SAM (serviceable addressable market), and SOM (serviceable obtainable market) — with bottoms-up calculations. How many potential customers exist? What's the realistic ACV? What's the achievable market share in 5 years?

Include market dynamics: Is the market growing? What's driving the growth? Are there regulatory tailwinds or headwinds? Is this a new market being created or an existing market being disrupted? Partners care more about the market trajectory than the current size.

Section 4: Product and Technology

What does the product do? How does it work? What's the technology differentiation? Is there a moat? This section should be specific enough that a partner who hasn't seen the demo understands the product. Include screenshots or diagrams if helpful. Address whether the technology is proprietary, how defensible it is, and what the product roadmap looks like over the next 12–18 months.

Section 5: Team Assessment

At seed stage, the team IS the investment. Evaluate the founders' relevant experience, domain expertise, co-founder dynamics, and ability to recruit. Include reference checks — not just what the founders gave you, but backdoor references you found independently. Be honest about gaps. Every team has them. Partners respect a memo that says "the CEO is a strong technical founder but has never managed a sales team — we'd need to help hire a VP Sales by Q2" over one that pretends the team is perfect.

Section 6: Competitive Landscape

Never write "there are no competitors." There are always competitors — even if they're spreadsheets and manual processes. Map the competitive landscape honestly. Include direct competitors, adjacent competitors, and potential entrants (big tech companies that could build this). Explain why this company wins. Be specific: "Acme's data integration handles 50+ ERP systems vs. Competitor X's 12" is better than "Acme has better technology."

Section 7: Business Model and Unit Economics

How does the company make money? What are the gross margins? What does the LTV/CAC ratio look like? For SaaS companies: ARR, MRR growth, net revenue retention, churn rate, and payback period. For marketplaces: GMV, take rate, and unit economics per transaction. If the company is pre-revenue, model the expected economics based on comparable companies and the pricing strategy.

Section 8: Traction and KPIs

Numbers, not narratives. Monthly revenue for the past 12 months. Customer count and growth. Pipeline and conversion rates. Engagement metrics. Cohort analysis. Show the data in tables or charts. Highlight the metrics that are genuinely impressive and be transparent about the ones that aren't. Partners will find the weak spots anyway — it's better if you surface them first.

Section 9: Deal Terms and Valuation

What's the proposed investment amount? What's the pre-money valuation? What ownership will we get? What are the key terms (liquidation preference, anti-dilution, board seat, pro-rata rights)? How does the valuation compare to comparable recent rounds? Is there a co-investor and who are they? Model the return scenarios: what does this look like at 5x, 10x, and 50x the current valuation? What exit multiple gets us to a 3x fund returner?

Section 10: Key Risks and Mitigants

This is the section partners read first. List 4–6 risks, ranked by severity. For each risk, provide a mitigant — the reason you believe this risk is manageable. Be intellectually honest. The purpose of this section isn't to dismiss risks. It's to show you've thought about them seriously. Common risks: market timing, team gaps, competitive response, customer concentration, regulatory risk, and technology risk.

Section 11: Recommendation

State your recommendation clearly. "I recommend we invest $8M to lead Acme's Series A" or "I do not recommend this investment." Summarize the 2–3 strongest reasons for your position. If you're recommending investment, include any conditions (e.g., "contingent on hiring a VP Sales" or "at a $28M pre, not the requested $35M"). If you're passing, explain what would change your mind.

How Partners Actually Read Memos

Here's what nobody tells junior VCs: partners don't read memos front to back. They read the executive summary. Then they skip to the risks section. Then the recommendation. If those three sections are compelling, they'll go back and read the market opportunity and traction sections. The team section usually gets a skim — they'll form their own opinion after meeting the founders. Product and competitive sections are read only if the partner isn't already familiar with the space.

This means your executive summary, risks, and recommendation need to be the strongest parts of your memo. Front-load the conviction. Don't bury the lead.

Common Mistakes That Kill Memos

Being too positive. The memo's job is to stress-test the deal, not sell it. If your memo reads like the founder's pitch deck, you've failed. Vague market sizing. "The market is $50B" tells partners nothing. Show your work. Ignoring competitive threats. Every company has competitors. Pretending otherwise destroys your credibility. No clear recommendation. "This is an interesting company" is not a recommendation. Take a position.
