The Monthly Investor Update: A Ten-Minute Version That Actually Gets Sent

You sent a good one in month one. Month two was easier, because you knew the shape of it. Month three went out a few days late.

Then month four was the month the churn number went the wrong way, and you decided to wait until you had something better to report. Month five you were heads down shipping. It is now five months later, and sending an update would mean explaining why there have not been any, so the drafts stay in your drafts.

This is how almost every solo founder's investor updates end. Not with a decision to stop, but with one skipped month that never gets recovered.

The templates are not written for you

Search for an investor update template and you will find a good deal of solid advice: highlights, lowlights, metrics, cash and runway, one clear ask, front-load the numbers, keep it to a page. Most of it is genuinely correct.

It is also written for a company with a team. It assumes someone can pull the numbers, that there is a monthly rhythm already in the business, and that writing the update is a task to be delegated or at least scheduled. The advice about formatting is thorough because formatting is the part a company with an analyst still gets wrong.

You do not have that problem. Your update is not badly formatted. It is unsent. So the useful question is not what a perfect update looks like, it is what a version you will still be sending in month eleven looks like.

That version is shorter than anyone recommends.

The five lines

Every update is the same five lines, in the same order, every month. The sameness is the point: a fixed format turns writing into filling in blanks, and filling in blanks takes ten minutes.

One sentence on the month. Good month, hard month, quiet month, and why. This is the line most people leave out and the only one some readers get to.

Two or three numbers. Revenue, customers, and whatever single number actually describes your business. Pick them once and never change the definitions, because a metric that changes definition is worse than no metric. If you have raised, add cash and runway, because that is the number your investors are quietly working out anyway.

The hardest thing, and what you are doing about it. One problem, honestly named, with the next action attached. Not a list of everything imperfect.

What is next. The one or two things you are actually working on before the next update. Short, and specific enough that next month's update can report on it.

One ask. Exactly one, and specific enough to be actionable: an introduction to a named kind of person, a hire you are looking for, a question you want an opinion on. "Any thoughts welcome" is not an ask and gets no replies. If you genuinely need nothing, say no ask this month, which is a perfectly good line and makes the months you do ask land harder.

That is it. Nothing about strategy. No appendix. No deck.

What it looks like written down

Subject: [Company] update, September

Hi all,

Steady month. Revenue up a little, but the real news is that the onboarding rewrite landed and activation moved for the first time since spring.

• MRR: £4,100 (from £3,750)
• Paying customers: 71 (from 66)
• Activation (signup to first reminder set): 38% (from 29%)

Hardest thing. Two of the three churned accounts this month were people who never set a second reminder, so the activation fix came a month too late for them. I am adding a seven-day check on accounts that go quiet after signup.

Next. Shipping the import flow, and starting outbound to accountants, which is the one segment where word of mouth already works without me.

One ask. I am looking for an introduction to anyone running a small accountancy practice (2 to 10 people) who would take a fifteen-minute call. That segment is the clearest signal I have and I only know three of them.

Thanks as always, Martin

Around 200 words. Readable on a phone at a bus stop, which is where it will be read.

Notice the ask. It is narrow enough that a reader either knows someone or does not, which means they can answer it in one line. A vague ask requires the reader to do the thinking, and readers with twenty portfolio companies do not.

Who is actually on the list

Three groups, and the second is the one people miss.

Investors on the cap table. Monthly, no exceptions. They have money in and are owed the update whether the month was good or not.

People who said keep me posted. Angels who passed on timing rather than substance, funds who were too early for you, the operator who asked to be kept in the loop. Quarterly is plenty. This list is the most undervalued asset a pre-raise founder has, because these are people who have already decided they like the business and are only waiting for evidence. An investor who has watched your numbers climb for four quarters does not need a pitch, and that is most of what the relationship system for founders raising a round is quietly building.

Advisors and a few close customers. Optional, and worth it if they have ever given you a useful answer. A short update is the cheapest possible way to keep someone thinking about your business.

If you are bootstrapping and have no investors at all, the second list is still worth keeping and still worth writing to twice a year. It costs an hour a year and it means that when you launch something, or decide to raise after all, you are writing to people who already know the story rather than starting from cold.

Send the bad month

The skipped month is nearly always a bad month, which is precisely the one worth sending.

Silence does not read as neutral. An investor who hears nothing for four months does not conclude that you have been busy, they conclude that the numbers went sideways and you would rather not say. The story silence tells is reliably worse than the story you were avoiding telling, and you do not get to correct it.

There is also a more selfish reason. The founder who called a bad quarter early, said what they were changing, and then reported the change working has demonstrated something a good quarter cannot demonstrate. That is the record people remember when a larger fund asks them for a view on you.

So the bad month gets the same five lines. One sentence saying it was a hard month, the numbers as they are, the problem named, the fix in progress. It takes the same ten minutes and it is worth considerably more than the month where everything went up.

Where the ten minutes actually goes

The reason month four gets skipped is rarely reluctance. It is that writing the update means reconstructing four weeks from memory, at nine in the evening, from your inbox and a commit log. That job takes an hour and feels like homework, so it gets postponed, and once postponed it compounds.

The fix is to stop writing updates at month end and start collecting them as you go. Keep one running note for the month and add a line whenever something happens that would belong in the update: a customer says something sharp, a number moves, something breaks. Four or five lines across a month, thirty seconds each.

At month end you are not writing, you are editing. This is the same principle as writing contact notes before you get to the car: the detail is cheap while it is fresh and expensive to reconstruct later.

Restarting after a gap

If it has been five months, here is the entire recovery: send this month's update, with one clause acknowledging the gap, and carry on as though the run had never broken.

Long overdue, and back to monthly from here. September in short: [...]

No apology paragraph. No attempt to summarise everything since April. A long silence followed by a normal, useful update reads as a founder who got busy, which is what happened. A long silence followed by a long explanation reads as a founder managing a problem. The same logic applies to any contact you have left too long, which is most of what makes reconnecting after months of quiet less awkward than it feels.

Then pick the date. The last working day of the month, or the first Tuesday, it genuinely does not matter as long as it is a date and not an intention.

What makes it reliable

Three things, and none of them is discipline.

A fixed date, so the decision is made once rather than monthly. A fixed format, so the writing is filling in blanks. And something outside your head that tells you the date has arrived, because the month an update gets missed is always the month you were too busy to notice it was due.

That last one is the whole difference between a founder who sent eleven updates last year and one who sent three. A recurring reminder that arrives carrying the list and the last note with it turns the update into a ten-minute task on a known day. It is the same Who / What / When loop that keeps individual relationships warm, applied to a group: who is on the list, what you last told them, when the next one is due.

And it sits alongside, not instead of, the individual follow-ups. A group update is not the right tool for a specific investor who asked for a specific milestone, which is what the investor follow-up email is for. The monthly update is the background hum that means those individual messages never have to start from nothing.

Five lines, one date, ten minutes. Put the date somewhere that will remind you, and the eleventh update is no harder to send than the first.

FAQ

What should a monthly investor update include?

Five lines: how the month went in one sentence, two or three numbers that do not change definition month to month, the hardest thing and what you are doing about it, what you are working on next, and one specific ask. Same five, same order, every month. The consistency is what makes the update readable in thirty seconds and writable in ten minutes.

How long should an investor update be?

Short enough to read on a phone without scrolling twice, which is roughly 200 to 400 words. Investors are reading a dozen of these. The update that gets read is the one that puts the state of things in the first sentence and stops when it runs out of things worth saying.

How often should I send investor updates?

Monthly if you have investors on the cap table, quarterly if you are keeping a list of interested people warm before a raise. Pick the frequency you can sustain for a year rather than the one that sounds diligent. A quarterly update you actually send beats a monthly one that stops in March.

Should I send an update after a bad month?

Especially then. Silence after a hard month is read as a hard month you are hiding, and investors fill the gap with something worse than the truth. Naming the problem yourself, with what you are doing about it, is the single most credible thing a founder can put in writing.

What if I have not sent an update in months?

Send this month's update with one clause acknowledging the gap, then carry on as if the run had never broken. Do not open with an apology or a summary of everything that happened since. A long absence followed by a normal, useful update reads as a founder who got busy. A long absence followed by a long explanation reads as a founder in trouble.

Do I need investors to send an investor update?

No, and the version without investors is often the more valuable one. If you are bootstrapping, the people who said keep me posted (angels who passed on timing, advisors, a few customers who care) are a list worth updating quarterly. When you eventually raise or launch something, you will be writing to people who already know the story.
