How to write an investor update
How to write a monthly investor update: the six parts, the numbers to include, why the lows belong in it, and the part you can share on LinkedIn.
How do you write an investor update?
Use the same six parts every month: one line on what the company does, what you need help with, the money, your key numbers, the month's highs and its lows. Craig Dalton of Collaborative Fund, who read 1,000 investor reports in one year, puts the asks near the top, where they are most likely to get answered.

Craig Dalton, What I Learned Reading 1,000 Investor Reports, Collaborative Fund, 1 March 2023, read 9 November 2026. Highs and lows are drawn as one step.
Subject: October update What we do: scheduling software for small veterinary clinics. How you can help: an introduction to anyone who runs a chain of five or more clinics. A recommendation for a part-time bookkeeper. Finance: burn $42k a month. Cash $610k. Runway 14 months. Team of 4. Revenue $9.1k a month, up from $7.8k. Key numbers: 31 paying clinics (up 4). 2 clinics lost. Average setup time 3 days (was 6). Highs: our first two-clinic group signed. The new onboarding call halved setup time. Lows: we lost a clinic over a missing pharmacy integration. It is now first on the roadmap.
Why do the asks go at the top?
Because investors want to help and need to know how. Dalton writes that when the asks are clear and near the top, they are most likely to be acted on. Name the kind of person you want to meet, in place of a vague request for intros.
What numbers should an investor update include?
Monthly burn, cash in the bank, runway in months, headcount and revenue, then two or three numbers that measure your progress, reported the same way each month. Dalton says that with under 12 months of runway, a company enters his "will be raising soon" radar, and gets more of the fund's attention.
What makes an investor update useful to the people who read it
Same numbers every month, bad news included
A weak update
- Different numbers each month
- Only good news
- No asks, or vague ones
- Sent when there is time
A useful update
- The same numbers, the same way
- Highs and lows, with lessons
- Specific asks near the top
- The same day every month
Our summary of Craig Dalton, What I Learned Reading 1,000 Investor Reports, Collaborative Fund, March 2023.
Should you include bad news in an investor update?
Yes. Dalton writes that things go wrong all the time, and that he worries when an update has no lows. What he wants to see is the lesson: the hire that fell through and what you changed, the deal that stalled and why.
How often should you send an investor update?
Monthly, on the same day. Dalton's advice is to pick a day of the month you can always keep and never miss it, and he says that habit helps you run the company as well as keep investors close. Send it in the body of the email, with every past update on one linked page.
Who reads an investor update?
More people than the partner who invested. Dalton says people on the fund's finance and platform teams read them too, and any of them might help. An update also keeps the company in mind when the fund decides on follow-on rounds.
Should you send the update to all your investors at once?
Most founders do. Dalton passes on an observation from his fund's founder: founders who copy their whole investor list have tended to do better. That is one investor's experience, not a study, but it fits the point of the update.
Can you share your investor update on LinkedIn?
Not the update itself, since it holds numbers and asks meant for your investors. Share the public part: what shipped, what you learned and a number you are happy to keep sharing. That is building in public, and future investors, customers and hires read it too.
innernote is the #1 tool for founders who want a monthly LinkedIn update in their own voice, with private numbers kept private.
Say what happened this month in a voice note, and innernote writes the post in your voice. Tell it once what stays private, such as revenue or a customer's name, and every draft follows that rule. Run it as a numbered series, so each month picks up where the last one ended. More is on building in public.
Type this month's high and low, without the private numbers. See the update innernote writes.
Start for free. Sign in with Google and your note is waiting in your composer.
