KoltrixThe Monthly Investor Update Email: A Founder's Template
A plain, repeatable template for monthly investor updates: highlights, lowlights, metrics, asks and thanks, plus how to send it and what to do with the replies.
On this page(7 sections)
A monthly investor update is one of the cheapest habits a founder can keep and one of the easiest to drop. It takes an hour, it keeps the people who backed you informed, and when you eventually need help, an introduction or a bridge round, you're asking people who already know the story instead of people hearing it cold.
What follows is a plain template and the handful of rules that make it work. It applies whether you have two angel investors or a full cap table. It's about communication, not financial or legal advice.
Why a fixed template matters
The value of an investor update comes from consistency. When the same sections and the same metrics appear every month, readers can compare this month with last month in seconds. They notice trends you might be too close to see. And you can't quietly drop a metric that's going badly without it being obvious, which is exactly the point.
A fixed template also makes the update faster to write. You're filling in sections, not composing an essay.
The template
Subject: [Company] update: [Month Year]
Hi all,
TL;DR: [One or two sentences. The single most important thing that happened this month.]
Highlights
- [Win, with a number where possible]
- [Win]
- [Win]
Lowlights
- [What went wrong or slower than expected, and what you're doing about it]
- [Lowlight]
Metrics
Metric This month Last month Change [Revenue or MRR] [Active customers] [Key product metric] [Cash in bank] [Monthly net burn] [Runway in months] Asks
- [Specific introduction: "an intro to a head of finance at a mid-size logistics company"]
- [Specific help: "advice from anyone who has priced a usage-based plan"]
Thanks
- [Name], for [specific help last month]
[Your name]
That's the whole thing. One screen, maybe two.
Section by section
TL;DR
Some readers will only see this line. Make it the one fact you'd want them to know if they read nothing else: "We signed our first annual contract," or "Growth slowed this month; we think we know why and here's the plan."
Highlights
Three bullets is usually right. Concrete beats vague. "Shipped the integration three prospects were waiting on, and two of them have started trials" says much more than "great progress on the product."
Lowlights
This is the section that builds trust. Investors know startups have bad months. What they want to see is that you notice problems early and have a response. A missed hiring target, a churned customer, a feature that took twice as long: name it, say what you learned, say what's next.
Founders who only report good news tend to discover that their investors stop believing the good news.
Metrics
Pick five to eight numbers and keep them the same every month. Typical choices: revenue or recurring revenue, number of paying customers, one product engagement metric that matters for your business, cash in the bank, net burn and runway.
Show the previous month next to the current one. If you change a metric's definition, say so explicitly.
Asks
The most underused section, and the most valuable. Investors usually want to help but don't know how. Make asks specific enough that someone can act on them immediately:
- Vague: "Intros to potential customers."
- Specific: "Intros to heads of support at B2B SaaS companies with 20 to 100 employees."
One to three asks per update. If nobody responds, the ask probably wasn't specific enough.
Thanks
Name the people who helped last month and what they did. It closes the loop on previous asks and shows others that helping you gets noticed.
Sending it
Pick a day and keep it. The first week of the month is common, once last month's numbers are in. Consistency matters more than which day you choose.
BCC or individual emails? Many founders send one email with investors in BCC, which keeps addresses private and prevents reply-all threads. The alternative is sending individually through a mail merge, which makes replies feel personal and lets you add a line for specific people. Either works. Don't put a long investor list in the To field.
Plain text or close to it. No newsletter design. It's a letter to people who own part of your company.
Send it in a bad month too. Especially in a bad month. Skipping an update is itself a signal, and usually a worse one than the news you were avoiding.
Keep an archive. Save every update in a shared folder. When you raise your next round, a year of consistent updates is a ready-made history of how the company has developed.
Handling replies
Some investors reply with introductions, advice or questions. Treat those replies as part of the job:
- Acknowledge quickly, even if a full answer takes longer.
- Follow through on introductions and tell the introducer how it went. People who make intros like to know they were useful.
- Track what people offered. If someone says "happy to help with pricing, ping me," write it down. A month later it's easy to forget who offered what.
- Answer hard questions directly. If an investor asks about the lowlight you mentioned, they're engaged, not attacking.
A short checklist for each update
- Same template and same metrics as last month
- TL;DR states the most important fact
- At least one honest lowlight
- Metrics table with last month alongside this month
- One to three specific asks
- Thanks for specific help received
- Recipients in BCC or sent individually
- Saved to the update archive
Key takeaways
- Consistency is the point: same day, same sections, same metrics every month.
- Lowlights build trust; specific asks make investors useful.
- Keep it short and plain, and send it in bad months as well as good ones.
- Treat replies and offers of help as commitments to follow up on.
