What’s an Investment Memo? Guide for Startup Founders

If you're raising your first round, you've probably run into the term "investment memo." Most founders aren't sure what it actually is or whether they need to care.

An investment memo is a working tool. It forces you to pin down your startup's mission, the market you're going after, and how the business actually makes money, all in a form an investor can read. When you're talking to angels, VCs, or an internal investment committee, the memo often decides whether the conversation goes anywhere.

Here's what it is, why it matters, and how to write one that holds up.

What Is an Investment Memo?

An investment memo is a written document that lays out the key details of a startup and the terms of the proposed investment. Investors have traditionally written them for internal use, but more founders now write their own to shape the story before anyone else does.

It's a way to explain your business plainly. Think of it as a pitch deck without the slides, with the reasoning filled back in.

Common Sections in an Investment Memo:

• Company Overview
• Problem and Solution
• Product and Technology
• Market Opportunity
• Traction and Metrics
• Business Model
• Go-to-Market Strategy
• Competitive Landscape
• Team
• Risks and Mitigation
• Investment Terms and Use of Funds
• Exit Strategy

Why Every Founder Should Write One

Nobody's going to require you to submit a memo. Write one anyway, because the act of writing it forces you to clarify your thinking. A good memo can:

• Sharpen your pitch: You'll be ready for the hard investor questions.
• Build trust: It signals you've done the work.
• Align the team: Co-founders and advisors all see the same plan.
• Improve fundraising success: Investors reward clarity, and the memo gives them some.

When to Use an Investment Memo

• Before reaching out to investors
• As a leave-behind after meetings
• To align with co-founders and internal teams
• For investor syndicates or shared deals

Example Investment Memo Structure

A simple format you can follow as a founder:

1. Executive Summary

A short overview of what your company does, the market, your traction, and how much you're raising.

2. The Problem

The pain point you're solving and who actually feels it.

3. The Solution

Your product or service, and why it solves the problem better than what people use today.

4. Market Opportunity

How big is the market? What's the TAM (Total Addressable Market)? Why now?

5. Product and Tech

Your product's core features, the roadmap, and any technical edge you have.

6. Traction

Key metrics: revenue, users, retention, MRR/ARR, and the rest.

7. Business Model

How you make money. Early revenue, pricing tiers, freemium, whatever you're running.

8. Go-to-Market

Your growth plan. Organic, paid, partnerships?

9. Competitors

Who else is in this space, and how you're different.

10. Team

Who's building this. Founders and the key people around them.

11. The Ask

How much you're raising, what stage the round is, and where the money goes.

12. Exit Opportunities

Likely exit paths: acquisition, IPO, and so on.

Tools to Help You Build Your Investment Memo

You don't have to do all of this by hand. A few tools that help:

• Notion or Google Docs: Good for drafting with other people.
• Plox (plox.in): Share your memo with investors and track who viewed it, how long they spent, and which sections held their attention. Useful when you're iterating on the pitch.
• Figma: For visuals and UX mockups, if you have them.
• Canva or Pitch: For supplemental one-pagers.

Best Practices for Writing an Investment Memo

• Be concise and data-driven: Investors don't read for long.
• Lead with insight: Why does your company need to exist now?
• Tell a story: Make the memo as engaging as your deck.
• Proofread: Typos read as sloppiness.

Common Mistakes to Avoid

• Overloading with jargon
• Ignoring competition
• Being too vague on financials or use of funds
• Skipping the risks section

Conclusion

An investment memo is your startup story, your data, and your plan in one document. If you're serious about raising, write it early. It forces discipline, it tightens how you talk about the business, and it improves your odds of making the right impression.
