Investor update template: writing one from your notes

A useful investor update template has five parts: highlights, the same key numbers every month, lowlights, the decisions you made, and specific asks. The fastest way to fill it is from what you already wrote down during the month: your decision log and your meeting notes. The numbers come from the systems that hold them, not from anyone's summary of a meeting.

This guide gives a copyable monthly investor update, the steps to write it in under an hour, and the checks that stop a wrong figure from reaching the people who funded you.

How to write an investor update from your meeting notes

1. Fix the day. Pick a day each month, such as the fifth working day, and put it in your calendar. Consistency matters more than polish.
2. Pull the numbers from their source. Revenue from the accounts, users from the product database, cash from the bank. Put them in the same table as last month.
3. Read the month's decision log. Every decision worth recording is a candidate for the "What we decided" section.
4. Skim the month's meeting notes. Look for customer quotes, hires, losses and anything that surprised you.
5. Write the lowlights before the highlights. They are harder to write, and doing them first stops them from shrinking.
6. Write the asks. Each one names who you want, why, and what a good introduction looks like.
7. Check every figure a second time. Anything that came from memory or from a meeting note gets checked against its source.
8. Send it, and file it. Keep each update with your notes so next month's comparison is easy.

What each part is for

Highlights

Two or three things that moved. "Signed Northwind, our largest customer so far" is a highlight. "Great momentum across the board" is not; it gives an investor nothing to repeat to anyone.

Numbers

The same small set every month, with last month beside this month. Changing which numbers you report is the first thing an experienced investor notices. If a number got worse, it stays in the table and the reason goes in the lowlights.

These figures come from the systems that hold them. A number someone said in a meeting ("I think we're at about forty customers") is a lead to check, not a source.

Lowlights

The section investors read most carefully. A deal that slipped, a hire who left, a launch that was late. Write what happened and what you are doing about it, in a sentence or two each. A month with no lowlights reads as a month where the founder is not saying something.

What we decided

This is where your decision log pays for itself. A line per decision, with the reason: "We stopped the reseller trial. Two of three resellers had no customers after 60 days." Investors see how you think, and you get a record of when each call was made.

Asks

The part that gets you help. Be specific: "An introduction to someone who has run finance at a company selling to hospitals" gets answered. "Any intros welcome" does not.

Thanks

One line naming who helped. It costs nothing and people keep helping when they see it mattered.

Your meeting notes as the source

Most of what goes in an update was said in a meeting first: a customer describing why they signed, the pricing discussion, the weekly review where the hiring plan changed. If those meetings have notes, the update is mostly a matter of reading them back.

What to pull from which meeting:

Two cautions. First, a customer's words in a call were said to you, not to your investors. Quote a customer by name only if they have agreed; otherwise describe them ("a logistics customer with 200 staff"). Second, updates get forwarded. Anything said in confidence in a meeting stays out.

Checking figures from AI notes

AI summaries are good at turning an hour's talk into a page, and they sometimes get numbers wrong: a figure attached to the wrong month, an estimate turned into a fact, a target reported as a result. In an investor update, that is a figure your investors will hold you to.

The rule is simple: no number goes into the update from an AI note without being checked, first against the transcript (was it actually said, and as what?) and then against the source system (is it true?). How accurate AI meeting summaries are explains how to check one quickly.

How Notey fits into this

Notey records calls on your Mac and transcribes them on the device, with your side and the other side on separate tracks. For an investor update, what matters is finding things again: ⌘K searches every meeting by time or by what was said, so "Northwind" or "reseller" brings up each meeting where it came up, and each transcript line plays from its timestamp so you can hear exactly how something was said.

If you have an account, you can ask for a summary and action items, or use Ask Notey on one meeting ("What did Priya say about the hiring plan?"). It says when the transcript does not cover the question. Only the transcript text is sent, never audio, and the result is labelled as AI-generated. Notes export as Markdown, so you can paste the parts you want into your draft and rewrite them in your own words.

The people on your calls should know you are recording them. Notey does not join the call, so nobody sees it unless you tell them; how to ask for consent to record has wording.

Common mistakes

• Changing the metrics. Report the same numbers every month, including the bad ones.
• Only good news. It makes the good news harder to believe.
• Vague asks. Name the person you want to meet, or the question you want answered.
• Figures from memory or from a summary. Check them against the source.
• Stopping in a bad month. A missed update is read as bad news anyway, without the explanation.

The investor update is one of several meetings and documents a founder keeps a record of; types of meetings and the notes each one needs covers the rest.

Frequently asked questions

What should a monthly investor update include?

Two or three highlights, the same handful of numbers every month with last month beside them, the things that went wrong, the decisions you made, and specific asks. A line of thanks for help received is worth keeping.

How long should an investor update be?

Short enough to read on a phone in a few minutes. If a section needs more than a short paragraph, link to a document instead.

How often should a startup send investor updates?

Monthly is common for early companies, and quarterly for later ones. What matters more is that the updates keep coming, on the same day, in the same format, including in a bad month.

Should I include bad news in an investor update?

Yes. Investors read the lowlights to judge whether the rest can be trusted, and bad news they hear first from you is easier to help with than bad news they find out later.

Can I write my investor update with AI?

An AI can draft from your notes, but check every number against its source and every claim against what was actually said. Label what the AI wrote if you share it as such, and send it as your own words only once you have made it so.
