How to write an investor update founders actually send

A monthly investor update is a short email with five parts: a headline on the month, your core metrics, what changed since last time, what you need help with, and your cash and runway. Write those five in the same order every month, keep it to one screen, and send it on a fixed date whether the month was good or bad.

The updates that get read are the consistent, slightly boring ones. The ones that never get sent are the ones a founder tried to make impressive first.

What goes in a monthly investor update?

A monthly investor update covers five things: one sentence on the month, three to six metrics with last month beside them, progress against what you promised last time, specific asks, and current cash and runway. Everything else is optional. If an investor cannot act on it, cut it.

• Headline. One sentence a busy reader can forward without editing.
• Metrics. The same three to six numbers every month, each with the prior month next to it.
• Progress. What shipped, what closed, what you learned.
• Asks. Named intros, specific hires, or one decision you want a second opinion on.
• Cash and runway. Cash in the bank and months of runway at current burn.

How do you write an investor update, step by step?

1. Pick the send date before you write anything. Choose a day, for example the fifth of the month, and treat it as a deadline you owe your investors. The date is what makes the habit survive a bad month.
2. Write the headline first. One sentence on the single most important thing that happened. If you cannot write it, you do not yet know what the month was about.
3. Pull the same metrics every month. Three to six numbers, each with the previous month beside it. Changing the metric set between updates is how founders accidentally hide a trend from themselves.
4. Report against your last update. Take the asks and goals from last month and say plainly what happened to each. This is the part investors use to judge whether you do what you said you would.
5. State cash and runway plainly. Cash in the bank, net burn, and months remaining. Investors will work it out anyway, and hearing it from you first is the trust signal.
6. Make every ask a named request. "Intros to two seed funds investing in fintech infrastructure" beats "any intros welcome". Give people something they can forward in ten seconds.
7. Send it, then log what came back. Note who replied, who asked a follow-up question, and who has now been quiet for three months. That list is the warm pipeline for your next round.

How long should an investor update be?

One screen. Aim for 300 to 500 words with the metrics as a short list, so the whole thing reads on a phone without scrolling twice. Detail belongs in an attachment or a link, not in the body. A long update is usually a sign the headline has not been decided yet.

How often should you send investor updates?

Monthly, until your board asks for something different. Mathilde Collin, the founder of Front, sent the same monthly note for years and only moved to quarterly after Front's Series B. Writing in First Round Review, she puts the consequence bluntly: "If you can't send your investors focused and consistent updates, you'll probably be one of those startups that doesn't make it."

Her other observation is the useful one for a first-time founder. She says two or three updates are enough for her to form a view on whether a company will work, and that the warning signs are founders who go quiet for four months and founders who change the format and the metrics every time.

Should you include bad news in an investor update?

Yes, in the month it happens. An investor who hears about a churned anchor customer from you can help. One who hears about it four months later learns two things, and the second one is about you.

Write it the same way you write the wins: what happened, what it cost, what you are doing about it. Do not soften it into a paragraph nobody can parse.

What if you are not raising yet?

Send updates anyway. The hardest part of a first raise is a list of investors who have never heard of you, and monthly updates are how a list of people who said "too early for us" becomes a list of people who already know your numbers. Six months of updates is a warm pipeline. A deck sent cold is not.

A monthly investor update template

Copy this structure and fill it in:

• Subject: [Company] update, [Month Year]
• Headline: one sentence on the month.
• Metrics: revenue or ARR, growth rate, net burn, cash in bank, runway in months, plus one metric specific to your business, each with last month beside it.
• Shipped: two or three lines.
• Lowlights: one or two lines, honestly.
• Asks: two named, specific requests.
• Thanks: the people who helped this month.

The update that actually gets sent

The best investor update is not the most polished one. It is the one that arrives on the same date every month in the same shape, with the same numbers, including in the months you would rather skip. Pick the date, pick the five sections, and let consistency do the work.

Boxsy drafts each month's update from the data already in your pipeline and integrations, so writing it is an edit rather than a blank page, and it tracks who opened it. Plans start at $49 a month.
