How to Write an Investment Memo: The VC Template That Actually Works

Most investment memos are bad. Not wrong, necessarily — just bad. They read like analyst homework assignments: tables of numbers, competitor grids, TAM calculations that could justify funding anything, and a thesis paragraph so hedged it says nothing.

The best memos read like arguments. Tight, confident, structured arguments that make a partner who has not met the company want to write a check. That is the standard. That is what you should be building toward.

This guide covers everything: what an investment memo is, why it matters, every section you need, how top firms structure theirs, the mistakes that get memos killed in partner meetings, and how to write the kind of thesis that actually moves people.

What an Investment Memo Is (And Why It Matters)

An investment memo is the internal document a VC firm writes to evaluate whether to make an investment. It is written after initial diligence and before — or sometimes during — a partner meeting where the decision gets made.

It is not a pitch deck. It is not a due diligence checklist. It is a document with a point of view.

The memo matters for several reasons:

It forces clarity. Writing is thinking. You cannot write a clean memo on a company you do not understand. The act of producing one forces the lead partner or associate to resolve ambiguity, articulate the real bet, and identify the holes.

It creates accountability. The memo becomes part of the firm's institutional record. When the investment wins or loses, you can go back and read what you believed at the time. The best firms use this to get smarter. The worst ignore it.

It aligns the partnership. Not every partner can meet every company. The memo is how you transmit conviction — or the absence of it — to the people who did not do the work.

It protects against FOMO. A memo that cannot articulate a differentiated thesis is a signal. Good partnerships use that signal. Bad ones override it because the founder is charismatic and a competitor just raised.

Pre-Memo vs. Post-Meeting Memo

Before we get into structure, it is worth distinguishing two common formats that serve different purposes.

The pre-meeting memo (sometimes called a screening memo or deal brief) is short — one to three pages — and written before the company has met the full partnership. Its job is to decide whether the deal is worth a partner meeting, not whether to invest. It answers: What is the company? Why are we looking at it? What do we need to believe to get excited? What are the two or three things that we need to validate?

The post-meeting memo (the full investment memo) comes after the partner meeting, after reference calls, after the deeper diligence sprint. It is longer — typically five to fifteen pages depending on the firm — and its job is to drive a yes/no decision. This is the document this guide is primarily about.

Some firms skip the full written memo for early-stage deals, relying instead on a decision meeting and a brief term sheet approval doc. That is a different culture. For anyone who wants a rigorous process, the full memo is non-negotiable.

The Anatomy of a Great Investment Memo

1. Executive Summary

The executive summary is the most important section. If someone only reads one section, it should communicate everything they need to form an initial view.

A strong executive summary covers: what the company does (one to two sentences, written for a non-expert), what stage and round this is, what you are recommending (invest / pass / conditional), the one-sentence thesis, and the two or three things that make this deal interesting.

That last part — the interesting things — is where most memos go wrong. Do not list five generic strengths. Pick the two or three signal factors that actually explain why you believe this company can win. If you cannot identify them, that is information.

Target length: Half a page to one page maximum.

2. Company Overview

This section gives context to a reader who has not seen the deck or met the founders. Cover: what the company does, the problem it is solving, its current product, how it makes money, and where it is in its development.

Be specific. "Enterprise SaaS platform for supply chain" is useless. "Warehouse management software for 3PLs that reduces mispick rates by integrating with existing WMS systems rather than replacing them" is useful.

Include the founding date, location, team size, and any notable investors or angels already on the cap table.

Target length: One page or less.

3. Market Analysis

This section contains the most abused content in venture. Every market analysis includes a TAM/SAM/SOM slide and a number large enough to justify the investment. That has become noise.

What actually matters:

Why now? What has changed in the last two to three years that makes this problem more solvable or this market more accessible than it was before? Regulatory shifts, new infrastructure layers, behavioral changes, cost deflation — something has to explain the timing.

Market structure: Is this a fragmented market with no dominant player, or are you going up against entrenched incumbents? How do customers currently solve this problem and how happy are they with it?

Bottoms-up sizing: Instead of citing a Gartner report, walk through the math. How many potential customers exist? What is realistic to charge them? What does penetration look like at 5%, 10%, 25%? That exercise reveals whether the opportunity is real or manufactured.

Target length: One to two pages.

4. Product and Technology

Explain what the product does and how it works, at a level that lets a partner evaluate differentiation without needing a demo. Cover:

• Core functionality and user workflow
• What is technically novel or difficult to replicate
• Current state: beta, launched, in production at scale
• Product roadmap and what gets prioritized next
• Any IP, proprietary data, or network effects built into the product

The key question to answer here: Why will this product be hard to copy in 18 months once a well-resourced competitor sees the traction?

Target length: One to two pages.

5. Team Assessment

The team section is where the real analysis lives, and where most memos are the weakest. Do not write a LinkedIn bio summary. Write an argument.

The argument structure:

Founder-market fit: Why is this specific founder the right person to build this specific company? What in their background gives them an insight, a network, or a capability that others do not have? A second-time founder who sold a company to the buyer they are now disrupting is founder-market fit. A former consultant who "is passionate about the space" is not.

Gaps: What does the founding team lack? Who do they need to hire? Is there a clear plan for filling those gaps? Being honest here builds credibility with the partnership and shows you actually did the work.

References: What did references say? Summarize the signal, not just the sentiment. "Three former colleagues said she will outwork anyone in the room and has pulled in enterprise contracts on personal relationships" is useful. "References were positive" is not.

Target length: One page.

6. Business Model

How does the company make money, and why is that model defensible?

Cover the pricing structure, how revenue is recognized, and the unit economics at the account level. For SaaS: ARR, ACV, expansion revenue potential, contraction, churn. For marketplace: take rate, GMV, supply-side vs. demand-side dynamics. For consumer: ARPU, LTV, payback period.

Also address scalability: as the company grows, does the unit economics improve (like a marketplace with network effects) or deteriorate (like an agency with linear headcount)?

Target length: One page.

7. Financials and Metrics

This section should be data-dense but narrative-light. Show the current state of the business in numbers:

• Revenue (ARR/MRR or trailing revenue depending on model)
• Growth rate (MoM or YoY)
• Key unit economics (CAC, LTV, payback, gross margin)
• Burn rate and runway at current pace
• Headcount and how it has scaled with revenue
• Historical actuals and projected trajectory

Do not torture the projections. If you are at Series A with $2M ARR and the model shows $200M ARR in four years, show it but also show what the realistic base case looks like. Partners have seen enough models to distrust everything; your job is to show them the key levers and explain what needs to go right.

Target length: One to two pages (plus appendix exhibits as needed).

8. Competitive Landscape

This section fails when it becomes a feature matrix with green checkmarks in every box. That is not analysis. That is marketing.

Real competitive analysis covers:

Who are the actual competitors — including the incumbent solution (spreadsheets, manual processes, a legacy vendor) that has the most market share today.

How customers decide — what factors actually drive the buying decision in this space, and how does this company fare on those factors.

Competitive moats — what builds over time that makes switching more costly: data, integrations, workflow dependencies, brand, regulatory relationships.

The competitive risk — if a large incumbent or well-funded startup decided to copy this product tomorrow, how hard would it be and how long would it take?

Target length: One page.

9. Deal Terms

This section is mechanics. Cover: round size, pre-money valuation, lead investor, pro rata rights, board composition post-close, any unusual terms (ratchets, full-ratchet anti-dilution, blocking rights), and your ownership percentage at entry.

Also include your return analysis: what does the company need to look like at exit to return the fund? At 3x, at 5x, at 10x — what does that require in outcome and what probability do you assign each?

Target length: Half a page.

10. Risks and Mitigants

This section is often written defensively, as if listing risks might kill the deal. That is backward. A thoughtful risk section builds credibility and shows the partnership you have not fallen in love with the deal.

Structure it clearly: name the risk, explain why it is real, and explain what mitigates it (or acknowledge if nothing does).

Common risk categories: execution risk (is the team capable of pulling this off), market risk (is the market real and large enough), product risk (does the technology actually work), competitive risk (can they maintain advantage), and financing risk (can they raise the next round at a reasonable price).

Target length: One page.

11. Recommendation

Close with a clear recommendation: invest or pass, and why. If it is conditional, name the conditions.

The best closing paragraphs name the core bet. Not the company's features. Not the market size. The bet: "We believe Sarah will be the first to put a compliant, AI-native audit workflow in front of the Big Four, and that the switching costs once embedded will make this a durable platform. The price is fair for that outcome. We recommend investing."

That is a memo that moves.

How Top Firms Structure Their Memos

Sequoia Capital

Sequoia is famous for its company narrative framework, which it also applies internally. Sequoia memos center on the why now and the insight — what does this team know that others do not? The format tends to be narrative-heavy at the top with data supporting the argument rather than driving it. Sequoia partners are trained to articulate the "why Sequoia invests" — the singular insight that makes the opportunity real — before any other analysis.

Andreessen Horowitz (a16z)

a16z uses a more structured format, reflecting its thesis-driven culture. Their memos tend to lead with a market thesis (not just a company evaluation), then evaluate the company against that thesis. The platform team and network value a16z can add gets explicit treatment — they want the memo to reflect not just whether the company can win, but whether a16z is the right partner. Deal memos are often preceded by an internal market memo on the category, which provides context before individual companies are evaluated.

Benchmark

Benchmark's partnership is small by design and its memos reflect that. They tend to be shorter, more opinionated, and structured around founder quality above all else. The Benchmark model is built on the thesis that great founders in real markets outperform great strategies, so their memos spend disproportionate time on team and comparatively less on market sizing. If you pull a vintage Benchmark memo, you will often find the market analysis section is tight and the founder section is deep.

The Anti-Memo Format

Some firms — particularly at the earliest stages — have moved away from formal memos entirely in favor of shorter, more opinionated formats. Common alternatives:

The decision brief: A single-page document answering three questions — what do we believe, what do we need to be wrong about to pass, and what has to be true for this to be a fund returner. Fast, forces prioritization.

The partner note: An informal memo written as a letter to the partnership, structured as "here is what I saw, here is what I think, here is what I recommend." Less clinical, more argumentative, more honest about uncertainty.

The pre-mortem: Some firms write a separate "why this could fail" document as a counterpart to the investment memo. Forces intellectual honesty and catches blind spots that enthusiasm creates.

None of these replace rigorous analysis — they just strip out the scaffolding that hides weak thinking behind formatting.

How to Write a Compelling Thesis Paragraph

The thesis paragraph is the most load-bearing sentence in the memo. It is where your point of view lives. If you cannot write it in two to four sentences, you do not have one yet.

The structure:

1. The insight: What does this team understand about the world that the market does not yet recognize?
2. The wedge: How does the product capture value from that insight today?
3. The endgame: If this works, what does it become and why is that outcome valuable enough to justify the risk?

Weak thesis: "CloudAudit is a well-positioned company in the growing audit automation market with a strong team and differentiated product."

Strong thesis: "Audit partners at mid-market accounting firms spend 60% of their time on document collection and reconciliation that software could handle — but the Big Four have failed to build it because it would commoditize their billable hours. CloudAudit's API-native approach threads that needle, starting with firms that want to grow headcount without adding partners. If they own this workflow across 2,000 mid-market firms, they own the audit data layer — which is worth more than the SaaS fees."

The difference is specificity and argument. The strong version tells you what the team knows, why they can win, and why it matters.

Common Mistakes That Kill Memos in Partner Meetings

Generic TAM. Citing a $50B market without explaining how the company reaches it does not help. It signals that the analyst was filling in a template.

No contrarian view. If your competitive section just says the company is better on every dimension, nobody believes you. The credible memo names the real risk and argues past it.

Founder section as biography. A list of prior employers is not an argument. Tell us why those experiences make this founder capable of building this company specifically.

Buried recommendation. The memo circles for twelve pages and then says "we recommend exploring further." That is not a memo. That is a hedge.

Missing the bear case. The most common partner meeting question is "what does the world have to look like for this to fail?" If your memo never engaged that question, you will be caught flat-footed.

Conflating enthusiasm with analysis. Founders are often compelling. That is the job. The memo has to do the work of separating the signal from the salesmanship.

Tips From Real VCs on What Makes a Memo Persuasive

"Show me one thing I haven't seen before." The memo that wins the room is usually the one that brings a specific data point, a customer quote, or a reference check insight that nobody in the room already knew. Generic analysis bores partnerships. A surprising specific detail wakes them up.

"Tell me what you're betting on." Not what is going right. Not the feature list. The actual bet. The thing that either happens or doesn't — and if it happens, you win big. Clarity on the bet forces clarity on everything else.

"Name the thing that makes you nervous." Partners respect honesty. If you can name the one thing that actually worries you and then explain why you are going anyway, it signals that your conviction is real rather than motivated.

"Write the bear case first." Some investors draft the rejection memo before writing the investment memo. If you cannot write a coherent argument for why this is a bad investment, you may be too close to see it clearly.

"The memo is for the partner who is skeptical, not the one who already wants to do the deal." The sponsor almost always wants to invest — that is why they are writing the memo. The audience is the person who hasn't met the company. Write for them.

The VC Beast Verdict

An investment memo is a forcing function for clear thinking. The quality of your memo predicts the quality of your decision-making — not because the memo causes the decision, but because the discipline required to write a good one surfaces every question you have not yet answered.

The firms that write great memos make better investments over time. Not every time. But systemically, over hundreds of decisions, the rigor shows up in the outcomes.

If you are a VC writing memos, hold yourself to this standard: could someone who has never met this company read your memo and understand exactly what you are betting on, why you think it will work, and why the risk is worth taking? If the answer is no, keep writing.

The template is a starting point. The argument is the work.

“The memo is for the partner who is skeptical, not the one who already wants to do the deal.”
