How to write an investment memorandum that gets investors to say yes

Raising capital is one of the hardest things that you will do as a founder, and most of the advice out there focuses on the pitch deck. But businesses often overlook the investment memorandum. Your deck gets you in the room, but a well-written investment memorandum is what gives investors the depth they need to actually say yes, especially when you are not around to answer their questions.

If you're heading into a Series A or any serious fundraising round, this blog will help you understand what an investment memorandum is, what goes inside one, and how to write it in a way that builds real investor conviction.

What is an investment memorandum

An investment memorandum is the document that walks investors through your fundraising opportunity in full. It is the long-form version of your pitch deck. Your deck gets people interested in the vision. Your memo is what proves you can actually pull it off, covering your business model, market, financials, risks, and where the money goes.

But remember, don’t misunderstand that there is only one type of investment memorandum. There are many types you may need to use as per the requirement. Here are different types of investment memorandum you can refer to:

a. Deal screening memo: a quick early-stage write-up used to decide whether a deal is worth pursuing further

b. Investment committee memo: the internal memo a VC writes to get a deal approved by their committee

c. Due diligence memo: a detailed document prepared during the diligence process to dig into the finer details

d. Post-investment memo: a record created after the investment to track performance and key decisions

e. Exit strategy memo: a memo focused on how and when investors can expect a return

f. Co-investment memo: used when multiple investors come together to back the same deal

g. Impact investment memo: built around social or environmental outcomes alongside financial returns

h. Private equity or venture capital memo: tailored to the specific requirements of PE or VC firms

i. Strategic partnership memo: used when an investment is tied to a broader business partnership

Why write an investment memorandum at all

A lot of founders skip this step, assuming that their pitch deck is enough. That's usually a mistake, especially at Series A and beyond. A strong investment memo does several things a deck simply can't. It speeds up investor decision-making by giving them everything they need before the first call, it helps VCs build internal consensus by briefing their partners, and it answers most of the early diligence questions upfront so you're not stuck in endless back-and-forth.

There's also a legal dimension. A well-structured investment memorandum that includes the right disclosures reduces your exposure to disputes down the line, because it documents exactly what you told investors and when.

Also, the timing is important here. VC firms raised only USD $76.1 billion in 2024, the lowest since 2019. In such a fundraising environment, founders who show up with a clear, complete investment memorandum are simply better prepared.

Investment memorandum vs offering memorandum: what's the difference

The terms investment memorandum and offering memorandum are often used interchangeably, and the content is nearly identical. They both have business overview, statutory financial reporting, risks, etc. The difference between them is the context, and what they are being used for.

[Table:1]

What goes inside an investment memorandum: a section-by-section breakdown

Here's what investors are actually looking for in each section of a strong investment memorandum.

Executive summary

The executive summary is one of the first things that any investors will read, and in many cases, it's the only thing they read before deciding whether to go further. That means it needs a lot of important information in a very small space.

You want it to cover what your company does in plain, simple language, the problem you're solving and why it matters right now, your funding ask and exactly what you plan to do with it, your top 3 traction metrics, and your investment thesis in a way that anyone can follow without needing a finance background. If the executive summary doesn't pull them in, the chances of them reading the rest of the memo are very less.

The problem and your solution

This is the section where you make the case for why your company needs to exist in the first place. Start by defining the problem as clearly as you can and backing it up with real data, because a vague problem statement won't convince anyone of anything. From there, walk investors through why the solutions that already exist fall short and why the timing is right for what you're building.

Market opportunity

This is where you show investors just how big the opportunity really is. You'll want to lay out your total addressable market (TAM), your serviceable addressable market (SAM), and a realistic near-term target you can actually go after, and back all of it up with sources investors can trust.

[Table:2]

Avoid inflated top-down TAM numbers that aren't grounded in real data. Investors see through them immediately, and it undermines your credibility in the sections that follow.

Business model

This is where you explain how your business actually makes money, and the key here is to be as specific as possible. Explain your revenue streams, whether that's subscription, usage-based, transactional, or a mix of a few, and then get into your pricing strategy and the unit economics : your customer acquisition cost (CAC), lifetime value (LTV), and gross margin.

Traction and milestones

Out of every section in your investment memorandum, this is often the one that does the most convincing, simply because it shows investors what you've already pulled off before they have put in a single dollar. So this is the place to bring in your monthly and annual recurring revenue, how many customers you have, how well you're keeping them, and any partnerships or pilots worth shouting about.

Team

Take investors through each founder's background and be clear about what gives your team an edge that others in your space don't have. Call out your key hires and any advisors who genuinely add weight to what you're building. The part founders tend to skip is being honest about the gaps on the team, but it's worth doing, because openly naming what's missing and how you plan to fix it almost always sits better with investors than a perfectly polished story that feels too good to be true.

Competitive landscape

A strong investment memorandum doesn't shy away from competition. It maps it honestly and shows exactly where you win. Acknowledge where your competition is stronger as the investors will respect your honesty far more than a slide that claims there's no real competition.

Financial projections

Include at least 3 years of projections, broken down quarter by quarter, so investors can see how your business grows over time. But the numbers themselves are not what convince anyone. What investors are really judging is the thinking behind them, whether your model reflects how your business actually works or just optimistic guesses on a spreadsheet.

Investors will also check how your projections tie back to your formal accounts, so it helps to know what a statutory report is before you start building them.

Your revenue assumptions come first: how you actually plan to grow, whether that comes from new customers, expansion, or pricing. Your gross margin comes next, along with what drives it, because a margin that improves over time shows your business gets more efficient as it scales. Then there are your operating expenses, broken down across headcount, sales and marketing, and overheads, so investors can see how your spending moves against your revenue. When these line up into a picture that holds together, you have shown investors you understand how your own business runs.

And if you are early-stage and not yet sure what a statutory report is or how detailed yours needs to be, that is fine. Just be clear about which numbers are audited and which are your own internal estimates.

Funding ask and use of proceeds

Be precise about what you're raising and exactly how you plan to spend it. Vague use-of-funds sections kill investor confidence fast. The more clearly you can connect each dollar to a specific milestone, the more confidence investors have that you'll deploy their capital well.

Say you are raising USD $2 million. Do not just say it is for "growth." Break it down: 40% to product so you can ship your next release, 35% to sales and marketing to land your first 100 enterprise customers, 20% to key hires like a CTO and head of sales, and 5% to operations and compliance. When every chunk ties to a clear outcome, investors can see exactly how their money turns into milestones.

Risk factors

Walking investors through your biggest risks feels counterintuitive when you are trying to win them over, but it is one of the smartest moves you can make. It tells them you see the whole picture, not just the upside. Cover your 3 to 5 biggest risks, and for each one, show how you are planning to handle it.

So what kind of risks are we talking about? A few that come up again and again:

1. Market risk: customers adopt slower than you expect, or the market turns out smaller than you thought
   
2. Regulatory risk: rules shift in spaces like fintech or healthcare and change what you are allowed to do
   
3. Competitive risk: a bigger, better-funded player moves in on your space
   
4. Key-person risk: the business leans too heavily on one or two people
   
5. Financial risk: you fall behind on covenant compliance tied to existing debt or funding agreements
   

Once you have named the risks that genuinely apply to you, from market adoption to covenant compliance, pair each one with an honest plan to deal with it. Investors respect founders who think clearly about what could go wrong, not just the ones selling a perfect future.

How to write an investment memorandum: the process

Here is how you can write an effective investment memorandum:

1. Start with your thesis, not your template: Before you start working on the memorandum, spend time answering one question: why should a rational investor put money into your company right now? If you can answer that clearly in 3 sentences, the rest of the memo will be much easier to write
   
2. Lead with the investor's question, not your features: Every section of your investment memorandum should eventually be answering what investors are really thinking: "what does this mean for my returns?" Showcase your offering keeping this question in mind
   
3. Back every claim with data: Generalities sound like plain marketing copy. But having data like "We grew 40% month-over-month for 6 consecutive months" is infinitely more persuasive than "we're growing fast"
   
4. Write the way you talk to a colleague: If you would feel awkward saying it in a real conversation, don’t mention it, just use clear, honest language that explains what you're building and why it matters
   
5. Keep it under 15 pages: Usual memorandums have 8-12 pages, and longer is not better. The investors will stop at the first sign of padding, so make sure every page is earning its place
   
6. Get a second read from someone outside your company: If they have questions after reading it, those questions belong in the memo. The goal is a document that answers investor questions before they're asked

Your investment memorandum is a reflection of how you think

Here is what most businesses miss: investors are not just reading your investment memorandum to evaluate your business model, but they're evaluating you as a founder. How clearly you explain your market tells them how well you understand it. How honestly you present your risks tells them how self-aware you are. How specifically you break down your use of funds tells them whether you're ready to be accountable to outside capital.

A well-written investment memorandum signals something that a pitch deck rarely can: that you think clearly, communicate honestly, and are genuinely prepared for what comes after the wire hits.

Once you've closed your round, the next challenge is putting that capital to work across markets. The Aspire Business Account¹ lets you hold and move money in multiple currencies, issue corporate cards² to your team, and track every dollar spent in real time, so the money you just raised goes exactly where your memo said it would.

Frequently Asked Questions

What is the difference between an investment memorandum and a pitch deck?

A pitch deck is visual and built for a live presentation, while an investment memorandum is a written document investors read on their own time. You need both. The deck gets you the meeting, and the memo builds the conviction to close it.

What is an investment memo used for inside a VC firm?

VCs write an investment memo internally to present a deal to their investment committee. When you write your own, investors can often use it to fast-track that internal approval step.

How long should an investment memorandum be?

For early-stage rounds, 8–12 pages is the right range.

Is an offering memorandum the same as an investment memorandum?

Largely yes. An offering memorandum covers the same core content but is more commonly used in private equity and M&A contexts rather than VC fundraising.

Do I need a lawyer to write an investment memorandum?

You can draft it yourself, but have a lawyer review it before sending it widely, especially around risk disclosures and SEC private placement rules if you're raising in the US.
