How to Write an Investment Memo: Template and Examples

An investment memo is how a VC convinces their own partnership to write a check. It's not a pitch deck. It's not a due diligence summary. It's a structured argument — part analysis, part conviction, part risk management — that answers one central question: why should this fund invest in this company, at this price, right now?

If you're a VC writing your first IC memo, this guide walks you through the full structure, explains what belongs in each section, and shows you what separates a memo that gets funded from one that gets tabled.

If you're a founder, reading this guide will tell you exactly what investors are analyzing when they're looking at your company — and what gaps to close before you get to the IC.

Deal Memo vs. Formal IC Memo

Most funds use two types of memos.

Deal memo (or initial memo): Written after 2-3 conversations with a founder. Usually 1-3 pages. Enough detail to bring to a Monday partner meeting and get a green light for deeper diligence. Covers the opportunity, why it's interesting, what the ask is, and the key questions you need to answer before recommending an investment.

Formal IC memo (investment committee memo): Written after full diligence is complete. Typically 8-20 pages depending on the fund and stage. This is the document the full partnership votes on. It must be thorough enough that a partner who's never met the founders can read it and make an informed decision.

Most analysts and associates spend 80% of their time on formal IC memos. Partners often write the final version with their name on it. The quality of your IC memo is a direct signal of your analytical rigor as an investor.

The 11-Section IC Memo Structure

1. Executive Summary

The most important section. Write it last, but put it first.

The executive summary should be 3-5 paragraphs maximum. It must answer:

• What does the company do (one sentence)?
• What is the market opportunity?
• Why is this team uniquely positioned to win?
• What are the key risks?
• What is the recommendation (invest/pass) and why?

Common mistake: Writing a generic executive summary that could describe fifty companies. If someone read just this section, they should understand the specific thesis for this deal.

Example of a weak exec summary opener: "Company X is a SaaS platform helping businesses optimize their operations."

Example of a strong one: "Fieldlens is the only construction project management platform built specifically for subcontractors — a segment that represents 60% of construction labor and has been ignored by Procore and Autodesk because their enterprise sales motion doesn't reach them."

2. Company Overview

• What the company does, in plain language
• Founded when, by whom
• Current stage and funding history
• Headquarters and headcount
• Core product and how customers use it

Keep this factual and brief — 1 page maximum. This section doesn't make the case; it sets context.

3. Market Analysis

Three things matter here: size, growth, and timing.

Market size: Use a bottom-up approach, not just TAM/SAM/TEM theater. If a company claims a $50B TAM but their actual ICP is 2,000 enterprise companies with $50K ACV, the realistic market ceiling is $100M. That doesn't mean you don't invest — it means you understand what you're investing in.

Distinguish:

• TAM (Total Addressable Market): Everyone who theoretically needs this
• SAM (Serviceable Addressable Market): Who they can actually reach given their GTM
• SOM (Serviceable Obtainable Market): What's realistic in 3-5 years

Market structure: Is it fragmented or consolidated? Who are the incumbents and why haven't they solved this? What creates the opening — regulatory change, new technology, shifting customer behavior?

Timing: Why is now the right time? Markets that have "always existed" often aren't the right time for 15 years and then suddenly are. What changed? (Stripe benefited from OAuth and mobile banking. Airbnb benefited from the financial crisis and smartphone ubiquity. Both had timing insights baked in.)

4. Product

• What exists today vs. what's on the roadmap
• How customers discover, adopt, and expand usage
• Technical differentiation, if any
• Key integrations or platform dependencies
• Screenshots or demo notes if helpful

Be honest about where the product is vs. where the pitch says it is. A product that's "in development" should be described as such, not as "shipped."

5. Team

This is where most IC votes are actually won or lost at early stage.

Cover:

• Founder backgrounds — domain expertise, technical depth, prior companies
• Specific insights: have they worked inside this problem for years?
• Track record: prior exits, fundraising history, customer relationships
• Team completeness: what's missing and what's the plan?
• Reference check findings (at the IC memo stage, you should have done at least 3-5 references)

What to look for: Domain expertise, execution evidence (they built things, shipped products, sold to customers), founder-market fit (why them), and honest self-awareness. The founders who scare me are the ones who have no explanation for past failures.

Strong team section says: "Jane built and sold her previous company to Oracle in 2019. She spent 8 years as a software buyer at Fortune 500s before that. This is a problem she has lived. Marcus was employee #4 at Figma and built their API platform from scratch."

6. Business Model

• How do they make money (SaaS, transactional, marketplace, services, hybrid)?
• Pricing structure (per seat, per usage, per outcome, enterprise contract?)
• Current unit economics: CAC, LTV, payback period, gross margin
• Revenue at current stage and trajectory
• Expansion mechanics (net revenue retention, upsell, cross-sell)

At seed stage, you often don't have complete unit economics. That's fine — but show what you know and flag what's still an assumption. "Current blended CAC is $1,800, LTV is estimated at $14,000 based on 3-year average contract length, but we only have 18 months of cohort data to validate churn assumptions" is a credible statement. "LTV/CAC is 8x" without supporting data is not.

7. Traction

Numbers tell a story. Tell it accurately.

• Revenue: ARR, MRR, YoY growth rate
• Customer count and notable logos
• Pipeline and conversion rates
• Product metrics: DAU/MAU, NPS, churn, engagement
• Waitlist, LOIs, pilot customers (and be clear which is which)

The most important metric depends on the stage:

• Pre-revenue: pipeline, pilots, LOIs, design partner count
• Early revenue: growth rate, logo quality, renewal rates
• Series A+: ARR growth rate, NRR, CAC payback, margin trajectory

Honesty here builds credibility. If growth slowed last quarter, say why. If one big customer accounts for 40% of revenue, flag it. Partners who discover surprises in diligence that weren't disclosed in the memo lose trust fast.

8. Competitive Analysis

Not just a 2x2 matrix. A rigorous competitive section explains:

• Who are the direct competitors and what do they do well?
• Who are the indirect alternatives (including "do nothing" and "build in-house")?
• Why do customers choose this company over alternatives?
• What is the sustainable moat: network effects, data advantages, switching costs, distribution, IP?

Avoid the "we have no real competitors" answer — it signals naivety. Every real market has competition. The question is what makes the company defensible.

9. Deal Terms

• Investment amount being sought
• Pre-money valuation (or SAFE cap)
• Round structure (lead/follow, pro-rata rights)
• Your fund's check size and ownership target
• Post-money cap table (include fully diluted, show who else is in the round)
• Use of proceeds: how will they spend the money?

Include your fund's target ownership and whether you can get there at this price. If the round is competitive, note the dynamics.

10. Risk Analysis

The most under-written section in most memos. Don't write it to check a box — write it to demonstrate that you have genuinely stress-tested your conviction.

Categories of risk:

Market risks: Is the market real? Is timing right? Could the market shift before they can scale?

Competitive risks: What if Salesforce builds this? What if a well-funded competitor enters?

Execution risks: Can the team recruit? Can they sell enterprise? Can they handle hypergrowth operations?

Product risks: Does the technology work at scale? Are there technical dependencies that could break?

Regulatory risks: Is there regulatory exposure (fintech, healthcare, defense, crypto)?

Financing risks: Will they be able to raise a follow-on? What does the path to profitability look like if markets tighten?

For each risk, include your mitigation: why you think the risk is manageable or why the upside justifies accepting it.

11. Investment Thesis

This is your "why we're doing this deal" section — distinct from the executive summary. It should articulate:

• Why this opportunity fits your fund's thesis
• What has to be true for this to be a fund-returner
• What comparable exits or outcomes support the return case
• Your specific perspective that other investors may be missing

The best investment theses are contrarian. "Everyone agrees this is a good company" is not a thesis — it's a consensus trade, which usually means the price reflects that consensus. Your thesis should express some specific belief that isn't fully priced in.

Example thesis: "Most investors view this as a CRM replacement play. We think it's actually a workflow automation platform that will expand into adjacent categories the way HubSpot did. If they achieve HubSpot-like NRR (130%+), this is worth 15-20x on revenue at exit."

What Makes a Memo Fundable

The memos that get yes votes do three things:

First, they show real conviction. Not "this is interesting" but "here is the specific reason I believe this company wins in a large market." Conviction without analysis is arrogance. Analysis without conviction is a book report. Good memos have both.

Second, they anticipate the objections. Every great company has reasons not to invest. A memo that doesn't address the obvious objections makes partners wonder if the author thought of them. Bring up the concerns and address them directly.

Third, they're honest about what you don't know. At seed stage especially, there are real uncertainties. Acknowledging them while explaining why you're investing anyway demonstrates mature judgment. The partners who've been investing for 20 years have seen a hundred companies that looked perfect on paper fail. They trust analysts who are honest.

A memo that says "there's some execution risk on the enterprise sales motion because the CEO hasn't led enterprise sales before, but she's hired a VP of Sales with 12 years of Salesforce experience and has a clear hiring plan" will get more trust than a memo that glosses over the gap.
