Investment Memorandums Explained: A Detailed Guide for Founders

What is an investment memorandum?

An investment memorandum is a written narrative that presents your company and fundraising opportunity in a clear and structured way. It’s designed to let investors fully understand and evaluate your business without needing a live pitch, meeting, or slideshow.

Unlike a pitch deck, which is visual, high-level, and built to support a conversation, an investment memorandum is text-heavy and explicit. It is designed to be forwarded internally, reread, marked up, and compared against diligence findings.

Who writes an investment memorandum?

An investment memorandum can be written by different parties, depending on context:

a. Founders

In early and growth-stage fundraises, founders usually prepare the investment memorandum themselves. By presenting strategy, traction, economics, risks, and capital requirements in one place, the document helps investors understand the business and build conviction.

b. Venture capital or private equity firms

Investors, particularly venture capital and private equity funds, also prepare investment memorandums, but these are usually internal. After diligence, the deal team prepares an “IC memo” for its investment committee, setting out why the fund should invest and on what terms. 

c. Investment bankers or advisors  

In more structured processes, including large private rounds or M&A situations, investment bankers or financial advisors may prepare a formal investment memorandum. 

What is the summary of an investment memorandum?

The summary section, often called the executive summary, is the most heavily read part of an investment memorandum.

A useful summary explains: what the company does, who the customer is, what problem is being solved, and why the opportunity exists now. It should cover current traction or evidence of demand, the founding team, and the broad contours of the raise.

An investor should be able to read the summary in a few minutes and understand the full shape of the opportunity.

What to include in an investment memorandum

There is no prescribed format for an investment memorandum, and investors are generally flexible regarding its structure. It usually includes:

a. Company overview

‍A concise snapshot of what the company does, who it serves, and how it makes money. This should anchor the reader before diving into details.

b. Problem and solution

‍A clear articulation of the customer pain point, why it matters, and how existing alternatives fail to solve it adequately.

c. Market opportunity

‍Market size (TAM/SAM/SOM), growth trends, and key demand drivers.

d. Product and roadmap

‍What exists today, what customers actually use, and what will be built next. This section should tie the roadmap to customer needs and business outcomes, not just features.

e. Traction and metrics

‍Revenue, users, pilots, partnerships, retention, or engagement, whatever best demonstrates momentum at the company’s stage.

f. Business model

‍Pricing, unit economics, gross margins (where applicable), and assumptions around scalability. Investors look for evidence that the model can work at a meaningful scale.

g. Go-to-market strategy

‍How customers are acquired, onboarded, retained, and expanded.

h. Team

‍Founders, key hires, and relevant experience. The focus should be on why this team is uniquely positioned to solve this problem.

i. Risks and mitigations

‍An honest discussion of what could go wrong, including execution, market, regulatory, or competitive risks, and how the company plans to address them.

j. Use of funds

‍How the capital will be deployed over the next 12–24 months.

k. Capital structure

‍Existing funding, an overview of ownership, and the context of the current round.

l. Exit considerations

‍Plausible long-term outcomes, such as strategic acquisitions or public markets, presented realistically.

The depth of each section depends on the stage of the company. Seed-stage memorandums are typically lighter and more thesis-driven, while Series A and beyond require sharper metrics, clearer unit economics, and stronger evidence of repeatability.

How long should an investment memorandum be?

There’s no fixed or “correct” length for an investment memorandum. In practice, length is driven by stage and complexity.  A seed-stage company with limited operating history does not benefit from a long document padded with speculation. Conversely, a Series B or later company with multiple products, geographies, or regulatory considerations may need more space to explain itself clearly.

Final thoughts

For founders, an investment memorandum is less about fundraising theatrics and more about thinking clearly on paper. It forces you to articulate your business without slides, shortcuts, or live explanations, and in doing so, exposes gaps in logic, assumptions, or strategy early.

Done well, an investment memorandum becomes a quiet but powerful asset. It travels easily, aligns investor understanding, and gives decision-makers the confidence to engage seriously. It won’t replace conversations, but it will raise the quality of every conversation that follows.
