How to Write a Monthly Investor Update

Investor updates are one of the most underused tools available to founders after a round closes. Most founders treat them as a box-checking exercise and write something vague and upbeat once every few months. Investors notice. The ones who read consistently tend to be the ones who respond when you need something, whether that's a warm intro, a bridge check, or a reference call.

According to data from Visible.vc, startups that send consistent investor updates are twice as likely to raise follow-on funding compared to those that go quiet between rounds. The update itself is not just communication. It is relationship maintenance in document form.

This guide covers what to put in a monthly investor update, how to format it so people actually read it, and how to track whether they did.

How often should you send investor updates?

For most early-stage startups, monthly is the right cadence. It keeps investors informed without overwhelming them, and it gives you a consistent forcing function to review your own numbers.

As you move into a growth stage, quarterly updates often make more sense. Your business is more complex, your metrics take longer to shift meaningfully, and investors expect board-level reporting to fill in the gaps. During a fundraiser, increase the frequency. A brief bi-weekly note to active prospects keeps you visible without asking for anything.

The most important factor is consistency. Pick a cadence and stick to it. An investor who receives 11 monthly updates in a row knows when to expect the 12th. That predictability builds trust in a way that sporadic, enthusiastic updates never do.

What to include in your monthly investor update

Keep the update to around 250 words for monthly sends. Investors are reading dozens of these. Brevity signals that you respect their time and that you have enough control over your business to summarise it clearly.

A one-paragraph summary

Open with a single paragraph that captures the state of the business this month. Was it a strong month, a difficult one, or somewhere in between? Give investors a frame before they read the numbers. Something like, "March was our best month for new customers but a slower one for revenue, as two enterprise deals were pushed to April." One sentence. Direct. Accurate.

Key metrics

Include the metrics that reflect the current health of the business. For most startups, this means monthly recurring revenue (MRR), cash in the bank, monthly burn, and runway in months. Add one or two metrics specific to your model – daily active users, conversion rate, or gross margin, depending on what matters.

Show the number and the change from last month. Context matters more than the raw figure. An MRR of £80,000 means more when investors know it was £68,000 last month than when it appears in isolation.

Highlights and lowlights

This section is where most founders get defensive, which is a mistake. Investors who back early-stage companies know the business will have bad weeks. What they want to know is whether you can see the problems clearly and respond to them honestly.

Keep highlights specific. "Signed a pilot with a major retail chain" is more useful than "strong commercial progress". Keep lowlights equally specific. "Lost our head of growth to a competitor" tells investors something real. “Faced some hiring challenges" tells them nothing.

Your ask

Every update should end with a concrete ask. Investors who are kept in the loop want to help, but vague asks produce vague responses. Be specific: you are looking for an introduction to a procurement lead at a particular company, or you need a reference from someone who has worked with a specific enterprise sales process, or you want to know if anyone in their portfolio has solved a particular technical problem.

One ask per update. If you include four things, none of them will happen.

How to format the update

Email is the standard delivery mechanism for early-stage startups. A short, plain-text email that people can read in two minutes performs better than a formatted PDF attachment that requires opening another application. As your business grows and you have more data to visualise, a short slide deck can work well, but only if your metrics genuinely benefit from charts.

Send on a Wednesday or Thursday. Mondays are chaotic. By Friday afternoon, email is competing with everything else before the weekend. Mid-week sends consistently see higher open rates.

Pick a fixed date each month and send from the same email address every time. The familiarity matters. Investors recognise the sender before they read the subject line.

How to share your update and track who reads it

Sending a plain email is fine, but it tells you nothing about engagement. When investors ask questions that confirm they read the update carefully, you know the relationship is active. When they go quiet, you have no way to tell whether they missed the email, skimmed it, or read every line and had nothing to add.

Sharing updates through a tracked link — using a platform like Pitchwise — lets you see who opened your update, how long they spent on it, and which sections they returned to. That information is useful. If a particular investor reads every update but never engages, that tells you something different from an investor who opens immediately and replies within the hour.

For founders managing a larger cap table with angel investors, family offices, and institutional investors across different levels of involvement, tracked links also give you a passive way to qualify who is paying attention before your next raise.

What to avoid in investor updates

Spin is the fastest way to lose credibility. Investors who have been through multiple cycles can tell when numbers are being presented selectively. If revenue is flat, say it is flat and say why. If a key hire fell through, say so and say what you are doing next. Transparency is the currency of the investor relationship, and spending it selectively is more expensive in the long run.

Avoid burying bad news at the bottom. If there is a significant problem, put it near the top with your response to it. Investors who have to dig through five paragraphs of good news to find the bad news lose trust in the format.

Do not skip updates during difficult periods. This is the most common mistake. The months when a founder feels worst about the business are exactly when investors most need to hear from them. Going quiet signals panic, not professionalism.

Frequently Asked Questions

What should be in a monthly investor update?

A monthly investor update should include a brief summary of the period, key metrics with month-over-month comparison, specific highlights and lowlights, and a concrete ask. Most updates should be around 250 words. The goal is to give investors the information they need to stay engaged, refer opportunities, and make decisions about future participation — without requiring them to ask for it.

How long should an investor update be?

For monthly updates, aim for 250 words or fewer. Quarterly updates can run longer, up to around 500 words, because they cover a broader period and often include more financial detail. The right length is whatever lets you communicate the state of the business clearly without padding. If you cannot write a good update in 250 words, the problem is usually that you do not have a clear picture of the month yourself.

How often should I send investor updates?

Monthly is the standard cadence for seed and Series A companies. Quarterly works for later-stage companies with more complex businesses and active board structures. During a fundraiser, bi-weekly updates to engaged prospects are appropriate. The frequency matters less than the consistency. Pick a schedule and keep it.

What metrics should I include in an investor update?

Include MRR or ARR, cash in the bank, monthly burn rate, and runway in months. Add one or two model-specific metrics relevant to your business — active users, gross margin, net revenue retention, or customer acquisition cost, depending on your stage and type. Show the current figure and the change from the previous period. Three to four metrics in total are usually enough.

Should I send investor updates if the news is bad?

Yes. The instinct to go quiet during a difficult period is understandable but counterproductive. Experienced investors expect difficulty. What they are evaluating is how you handle it. An honest update that identifies a problem and describes your response to it builds more trust than a series of optimistic updates that ignore the situation. Investors who do not hear from founders during hard times often assume the worst.

Track who reads your investor updates with Pitchwise

If you send investor updates by email, you have no visibility into who reads them. Pitchwise lets you share your update through a trackable link, see who opens it, how long they spend, and which sections they return to. That data helps you have better follow-up conversations and qualify investor engagement before your next raise.
