How to write a monthly investor update that gets read

Most founders send investor updates that are either too long, too infrequent, or too focused on good news. The best investor updates are short, honest, and consistent. They take thirty minutes to write and save hours of ad-hoc investor communication. They build trust over time in a way that almost nothing else can.

This is a practical guide to writing updates that investors actually read and respond to.

Why investor updates matter more than founders think

The obvious function of an investor update is to keep shareholders informed. But it does several other things that are less obvious and arguably more important.

First, it builds a track record. An investor who has received twelve months of honest updates — including the bad months — has much stronger conviction going into your next round than one who only hears from you when things are going well. That conviction translates directly into the quality of the reference they give to your next lead investor.

Second, it activates your network. A good update gives investors something specific to help with. When you ask for a specific introduction or a specific type of candidate, the investor who reads your update has the context to act on it. Vague requests get vague responses.

Third, it disciplines your own thinking. Writing a monthly update forces you to articulate what’s working, what isn’t, and what you’re doing about it. That clarity is valuable even if no one ever reads the email.

The template

Keep the structure consistent every month. Investors will begin to read the sections they care most about first — that’s a feature, not a bug.

1. The one-paragraph summary

Three to five sentences. What happened this month, and what does it mean for the company’s trajectory? This is the only section some investors will read in full every month, so it needs to stand alone.

2. Key metrics

The three to five numbers that matter most for your business at this stage. Include the current figure, the figure from last month, and a brief note on direction. Do not pad this section with vanity metrics — it dilutes the signal.

Common metrics at pre-seed and seed: MRR or ARR, month-on-month growth rate, pipeline value, customer count, burn rate, runway.

3. Progress against last month’s goals

What did you say you were going to do last month? Did you do it? If not, why not? This section is the hardest to write honestly and the most valuable to read. It creates accountability without requiring a formal review process.

4. Goals for next month

Three to five specific, measurable goals. Not aspirations — commitments. These become the basis of the ‘progress against goals’ section next month.

5. Where you need help

The most underused section. Be specific: “We need an introduction to a procurement director at a mid-size NHS trust” is actionable. “Any healthcare connections would be great” is not. Investors want to help — make it easy for them to do so.

6. One thing that went wrong

Optional, but powerful. A founder who is willing to write honestly about a mistake or a setback is a founder investors trust. It doesn’t need to be dramatic — a product decision that didn’t land, a hire that didn’t work out, a customer conversation that revealed a gap. Honesty in the bad months is what makes the good months credible.

Format and frequency

Monthly is the right cadence for most early-stage companies. Quarterly is too infrequent to be useful for tracking momentum.

Keep the email to under 400 words. If you find yourself writing more, you are either including too much detail or deferring the hard work of summarising.

If you can, send it on the same day each month. Consistency signals professionalism and makes the update easier to write — you know it’s coming.

What to do if you’ve stopped sending updates

Most founders go through a period where updates lapse — usually during a difficult stretch when there is least appetite to share the news. The right move is simply to restart, acknowledge the gap briefly, and carry on. Investors understand that bad months are hard to write about. What they remember is whether you came back.

A simple rule: if you would be embarrassed for an investor to read this update, that embarrassment is the signal that you need to send it, not the signal to delay.
