What a VC Investment Memo Does (And Why Most Founders Misread It)

The Memo Gets Written After You Leave the Room

I see this every week - founders walking out of a pitch thinking the decision was just made. It was not.

The pitch is an audition. The VC investment memo is the verdict.

After you walk out of that meeting, the partner who liked your company has to convince everyone else. The memo is how they do it. It travels to people who have never met you, never heard your voice, and have no emotional stake in your story. It has to work without you present.

That is the frame everything else in this article follows.

What a VC Investment Memo Is

A VC investment memo is an internal document. A partner writes it to make the case for a deal to the rest of the firm. It covers the opportunity, the team, the market, the risks, the returns, and the reasoning.

A memo convinces someone reading alone at 11pm with no one to charm them.

The pitch deck grabs attention in a room. The memo convinces someone reading alone at 11pm with no one to charm them. As one practitioner put it, the goal of the memo is to let a partner understand the nuance of a thesis - something a deck simply cannot do.

The standard memo runs around 3,000 words. It goes to the investment committee before a final decision gets made. In many funds, no deal moves forward without one.

The Thesis vs. Book Report Problem

Here is the single most important thing to understand about what VCs want from a memo: they want a thesis, not a report.

A book report summarizes what already exists. It recaps the market data, lists the competition, describes the product. It reads like a Wikipedia article about your company.

A thesis connects dots that others have not connected yet. It argues a specific future that is not obvious. It explains why this team, this market, this moment adds up to something that looks underpriced today.

This distinction shows up clearly across practitioner discussions. VCs consistently flag that too many memos read like book report summaries. The components they want to see are: how the writer uniquely connected the data points, what future they are betting on, which assumptions they tested, where they could be wrong, and why the upside justifies the risk anyway.

The best memos make room for nuance. They let cause-and-effect relationships shine in ways that a slide deck never can.

The 8 Sections in Every Serious Memo

The structure is not a secret. Here is what every VC investment memo needs, with notes on where founders typically leave value on the table.

1. Executive Summary. Problem, solution, why now, capital ask. This is the hook. If the reader is not sold in the first 200 words, the rest gets skimmed.

2. Team. For early-stage deals, this is the most important section. Bessemer's pattern across decades of public memos is consistent - the best investment decisions centered on people. Early products are barely recognizable by the time a company hits scale. The founders are what endures.

3. Market Opportunity. TAM, SAM, SOM - but bottoms-up, not top-down. Saying you will capture 1% of a $10 billion market is not a thesis. Walking through the unit economics of how you reach $50 million in revenue is.

4. Product and Solution. What it does. How it works. What makes it hard to copy. Keep this section tighter than you think. The memo reader is not buying the product. They are buying the bet.

5. Business Model and Unit Economics. CAC, LTV, gross margin, payback period. Growth-stage memos go deep here. Early-stage memos can hold lighter on numbers but must show the logic of how money moves through the business.

6. Traction and Key Metrics. What you have proven so far. Net retention, gross churn, cohort behavior, logo growth. Be honest. VCs will check.

7. Competition and Defensibility. Who else is doing this and why you win. The weak version names competitors and says you are better. The strong version explains the structural reason why, once you have a beachhead, it is hard to displace you.

8. Risks and Key Assumptions. I see it in memo after memo - founders skip this section or soften it, and so do VCs. It is also the most differentiating. A memo that names the three ways this deal goes to zero - and then explains why those are acceptable bets - signals honest thinking. That builds more trust than a memo that pretends the risks are minor.

What the Sequoia YouTube Memo Taught Every VC

The most studied investment memo in venture history is the one Roelof Botha wrote for Sequoia on September 2, 2005. It was never meant to be public. It became public because Viacom sued YouTube over copyright infringement, and the memo was submitted as part of the legal proceedings.

That accident of litigation is why this memo is the most trustworthy public example in existence. It was not cleaned up for a blog post. It was not curated for a firm anniversary. It is exactly what Botha wrote the Friday before he asked the partnership to give him a decision by Monday.

What did that memo say? YouTube had just launched two months earlier. It had no CEO and no formal business model. Botha proposed a $1 million seed investment followed by a $4 million Series A for roughly 30% of the company.

The revenue model section was openly uncertain. Botha used scenario planning - projecting 10 to 30 million video views per day as a bull case that seemed ambitious at the time. YouTube now serves over 5 billion video views per day.

The risks section listed four genuine concerns - competition and defensibility, revenue model uncertainty, scalability, and copyright. He did not hide them. He named them and then made the case for the bet anyway.

Sequoia netted roughly $500 million on that investment - a 57x return - when Google acquired YouTube for $1.65 billion about a year after the memo was written.

Even the best VCs dramatically underestimated the outlier outcome. The memo did its job. It laid out a clear thesis. It named real risks honestly. The partnership had what they needed to make a decision quickly.

The Apple Memo That Almost Got Filed Away

Don Valentine's original handwritten memo proposing Sequoia's investment in Apple Computer is one of the most striking documents in venture history. Valentine called it a very rich deal and flagged the management as questionable. The $600,000 investment would buy 10% of the company at a $6 million valuation. Apple had $750,000 in net sales and about $60,000 in pre-tax earnings at the time.

Valentine projected those numbers would jump to $14 million in revenue and $700,000 in pre-tax profit in the following twelve months. He estimated the total market to be worth over $500 million. The deal still made him nervous. His own handwritten notes used the words very rich deal.

Sequoia exited a few years later with a healthy return. Apple went public shortly after at a $1.8 billion valuation - roughly 300 times what Valentine paid for his slice. Today Apple sits at a $3.8 trillion market cap.

This memo matters for a specific reason. It shows that even the founding text of one of the most important investments in tech history was written with doubt. Valentine did not need certainty. He needed a documented thesis that was defensible enough to act on.

The memo did that job.

How Bessemer Tracked Toast for 18 Months Before Writing a Word

Bessemer's Series B memo for Toast - the restaurant POS platform that eventually went public at a multi-billion dollar valuation - is one of the most detailed public examples of how a later-stage memo works differently from an early-stage one.

The BVP partners engaged with Toast for 18 months before investing. They spoke with 30 or more customers provided by the company, then did additional unannounced in-person visits on top of that. The memo opened not with a founder story, but with a financial summary. By the Series B, the numbers had to make sense on their own.

The investment was $17.5 million for roughly 15% of the company. The partners modeled out scenarios from a total wipeout to what the memo called goes nuts. Toast's actual IPO came in well above their wildest modeled outcome.

The single sentence that Bessemer said mattered most: we believe this is the best product team in the restaurant POS space. That is a thesis.

The Public Memo Problem

Almost no coverage of VC investment memos mentions this: the public examples are not a representative sample.

Bessemer only published memos for companies that went public or got acquired. That means you are reading about LinkedIn, Pinterest, Shopify, and Toast - not the hundreds of companies where the product never found a market. VCs have almost certainly written investment memos for companies that quietly failed and closed.

The Apple memo is handwritten notes that came out as part of a firm anniversary. Polished BVP memos may have been reviewed before publication. The YouTube memo is the only one that surfaced unfiltered, under oath, through litigation.

This does not make public memos useless. It means you should read them for structural logic, not as proof that this exact format guarantees a yes.

The Founder-Written Memo - A Rising Fundraising Tactic

Sophisticated founders are writing their own version of an investment memo before they ever get in a room with a VC. The goal is to think through and communicate the thesis in exactly the language a partner would use to pitch their firm.

The logic is straightforward. When a VC partner has two promising companies on their desk and one evening to write an IC memo, which deal moves forward? The deal where the partner already has a five-page document in the founder's own words, articulating the market, the model, and the risks.

Y Combinator's Series A guide recommends that founders send an investment memo to investors before the meeting. A memo sets the tone and elevates the quality of the conversation. When an investor reads your memo and still takes the meeting, you already know they are serious.

The practical implication is simple. Structure your memo the way a partner would write it about you. Lead with the thesis, not the product description. Name the risks before they do. Give them the sentence they will use in their IC meeting.

The LP Angle Most Founders Never Think About

VCs write memos for one reason that almost never gets mentioned in founder-facing content - their Limited Partnership Agreements often require it.

LP agreements I've reviewed require General Partners to follow a documented investment process, record their decision-making, and report investment rationale to the fund's limited partners. The memo is the paper trail that proves the GP operated within the fund mandate.

Fiduciary accountability is what this is. High-return VC funds do not take undocumented risk. They take concentrated, intentional risk within a governed structure - and the memo is how they prove it. The VC who loves your company still needs to write a memo that holds up to scrutiny from people who were never in that room. The better your story maps to their investment thesis, market focus, and stage mandate, the easier that memo is to write - and a deal moves faster because of it.

For founders, understanding this changes how you approach the relationship.

Early-Stage vs. Growth-Stage - The Memo Shifts Completely

The sections are the same. The weight is completely different.

At pre-seed and seed, the memo is mostly narrative and team conviction. There is often not enough data to build a rigorous financial model. The question the memo is answering is whether the firm believes in these people, this market, and this thesis enough to make a bet at this price.

By Series B, the memo flips. The Toast example shows this clearly. The opening is financial. The diligence is quantitative. Gross churn drives the model. Net retention tells you if the product works. CAC payback and revenue multiples are what the partners argue about in the room. Narrative still matters, but it supports the numbers rather than substituting for them.

I see this every week - founders pitching with the same deck regardless of stage. The best ones adjust their materials based on where the VC will be writing their memo from - and make that person's job as easy as possible.

If You Want to Speed Up Your Next Round

Write the memo yourself before you write the deck.

It forces you to state your thesis clearly, name the risks honestly, and articulate the specific bet you are asking someone to make.

When you understand what goes into the document that decides your deal, you pitch to that document - not just to the room.

The founders closing rounds faster right now are not necessarily the ones with the best decks. They are the ones who make a partner's job easier. The memo is where that happens.
