Investor update template: what to send every month

Here is an investor update template you can copy today: a subject line, a one-sentence headline, six metrics with last month beside each, highlights, lowlights, a report on last month's asks, this month's asks, and thanks. Below it is a fully worked example for a fictional seed-stage company, followed by three variants: pre-revenue, a bad month, and the update right after closing a round.

Keep the shape identical every month so investors can compare it with the last one in seconds. For the reasoning behind each section, read how to write an investor update. For the routine that gets it out on time, read keeping investors updated without an ops person.

What does a finished monthly update look like?

Illustrative example: Lanternfish is a fictional seed-stage company that sells scheduling software to veterinary clinics, and every number below is invented to show the format.

Subject: Lanternfish investor update, October 2026: first multi-location group signed

Headline: We signed our first multi-location clinic group, eleven sites on one contract, and had our first month with zero churn since June.

Metrics:

• Cash in bank: $1,840,000, last month $1,936,000
• Net burn: $96,000, last month $91,000
• Runway: 19 months at current burn
• MRR: $41,200, last month $37,900, up 8.7% month over month
• Paying accounts: 38, last month 35
• Appointments booked through Lanternfish: 21,400, last month 18,900

Highlights:

• Signed Harborview Animal Health, eleven clinics on one annual contract, after a ten-week pilot at two sites.
• Shipped two-way text reminders. No-shows at pilot clinics fell from 9% to 6% in the first three weeks.
• Our first account executive accepted an offer and starts on December 1.

Lowlights:

• Burn rose $5,000 on a one-off trade-show booth. Once both new hires start, burn will be about $118,000 a month, which still leaves about 15 months of runway.
• Our integration with the second-largest practice management system slipped to January. Their partner team has been slow to issue sandbox access.

Last month's asks:

• Intro to a clinic group operations lead: Priya introduced us to Harborview's COO. That is the contract above.

This month's asks:

• An intro to anyone on the partnerships team at a practice management software company.
• A second opinion on annual versus monthly pricing for groups over ten sites. Fifteen minutes on a call is plenty.

Thanks: Priya, for the Harborview intro, and Marcus, for reviewing our sales comp plan.

That is under 300 words, readable on a phone, and every line could be checked against last month's email.

What changes when you have no revenue yet?

Keep the template, swap the revenue lines for evidence that you are getting closer to it:

• Replace MRR with your leading indicator. Active users, weekly usage, pilots running, or signed letters of intent, whichever you would show an investor first.
• Report against the milestone you raised for. If the round was meant to get you to launch, say how far away launch is and whether the date moved.
• Keep cash, burn and runway. With no revenue, they matter more, not less.
• Say what you learned. One line on the most useful thing a customer told you this month is worth more than a feature list.

How do you use the template in a bad month?

Send it, on the date, in the same shape. Hoala Greevy, the founder of Paubox, writing for 500 Global, describes the habit simply: "I've sent monthly investor updates since December 2016. Every month. Good or bad."

Three changes to the template, nothing more:

• Put the problem in the headline. If the month was about a churned anchor customer, the headline says so.
• Move lowlights above highlights. Investors should not have to scroll past good news to find the thing that matters.
• Point the asks at the problem. A bad month is when a specific ask is most likely to get a useful answer.

Do not change the metrics set. Dropping the number that went the wrong way is the one thing investors will notice.

What do you send right after closing a round?

The first update after a close is the one new investors read most closely, because it sets their expectations for every update after it. Use the template with these additions:

• Thank every investor in the round. Name them, with their permission. Check with your lawyer before putting round terms into an email that will be forwarded.
• State what the money is for. The two or three milestones the round is meant to reach, and roughly when.
• Reset runway. New cash, expected burn as you hire, and months of runway at that burn.
• Announce the cadence. Tell everyone, old and new investors alike, the date updates will arrive from now on.
• Make the first asks. A new group of investors is a new set of networks. Ask for the hire or the customer intro you need most.

Can Boxsy fill in the template for you?

Boxsy's update engine drafts from a template, Boxsy's own or yours, and fills in the metrics from the control center, which pulls from QuickBooks, HubSpot and Plaid, or from numbers you enter in a monthly check-in. Drafts arrive on your cadence with a reminder, and nothing is sent until you have reviewed it, edited it and picked the recipients. After it goes out, you can see opens, reads and clicks.

Same template, every month

A template is only useful if it stays the same. The value of the update is in the comparison: this month against last month, this promise against what happened. Copy the structure, fill it in on the same date each month, and resist the urge to redesign it every time the news changes.

If you want the update cadence set up alongside your pipeline and data room before a raise, Boxsy Ready does it in four weeks. Or talk to our team about adapting the template to your business.
