Key Takeaways
- A monthly investor update is one page, six blocks: headline, key metrics, wins, lowlights, asks, cash and runway
- Send it on a fixed date every month, good month or bad — predictability is the signal, not the content
- Always state cash in bank and months of runway. An update without those two numbers reads as evasion to anyone who has funded a startup before
- The asks section is the point. Name the company, the role, or the number you want, not "intros would be great"
- Report the lowlights yourself. An investor who learns bad news from someone else stops trusting the good news
- Prospective investors who are not yet in the round belong on the same list — twelve updates is the cheapest due diligence you will ever run on yourself
- Updates compound: by the time you open a round, the people on the list have watched you hit or miss twelve months of numbers
An investor update is a short monthly email covering one headline, your key metrics with the prior month's comparison, wins, lowlights, specific asks, and cash in bank with months of runway. Keep it to one page, send it on the same date every month, and include prospective investors as well as current ones.
Most founders write updates when something good happens and go quiet when it does not. That pattern teaches every reader that silence means trouble — which means your quiet months do more damage than an honest bad update ever would.
What Goes in an Investor Update?
Six blocks, in this order, on one page. The order matters because most people read the first three lines and skim the rest; put the thing you most want remembered at the top.
Anything else — board changes, a long product narrative, a customer story — goes below that, or in a linked doc. Y Combinator's guides to what to expect from your investors and how to work with investors are useful calibration on how much attention you are actually competing for.
After a priced round the update often stops being optional. The information rights clause in a standard investor rights agreement — the form is published in the NVCA model legal documents — typically obliges the company to deliver financial statements on a set schedule. Writing a good monthly update before you sign one means the contractual version is just a formality.
The Monthly Investor Update Template
Copy this structure and keep it identical month to month. Consistency is what makes the numbers readable at a glance.
The format is boring on purpose. A reader who has seen eleven of these can extract the state of your company in fifteen seconds, which is exactly what you want when they are deciding whether to forward it to a partner.
Which Metrics Belong in the Update
Pick three to six metrics that genuinely drive your business, publish them every month without exception, and never swap one out because it turned ugly. Changing the metric set is the loudest possible signal that a number went bad.
By model, the defensible core:
Andreessen Horowitz's references on 16 startup metrics and 16 more startup metrics are still the clearest public write-ups of which numbers mean what, and which commonly-quoted ones mislead. Harvard Business Review's entrepreneurship coverage is a reasonable second source on how founders and boards actually read performance data.
Two rules that save you later. Define each metric once, in writing, and keep the definition. An ARR figure that quietly starts including pilots is how you fail diligence a year from now. And show the comparison, not just the level — a number with no prior month is a number nobody can read.
How to Write the Asks Section So People Actually Act
"Intros would be great" produces nothing. A named company, a named role, or a number produces responses. The asks section is the only part of the update that creates work for the reader, so it has to be specific enough that saying yes takes under two minutes.
Good asks look like this:
Cap it at four. An update with eleven asks gets zero, because the reader cannot tell which one matters.
What to Do When the Month Was Bad
Send the update anyway, lead with the bad number, and state what you are changing. A bad month reported clearly builds more credibility than a good month reported vaguely — because the person reading has seen dozens of companies and already knows that twelve consecutive good months do not happen.
The structure that works:
What destroys trust: going quiet for two months, burying the bad number in paragraph six, or reporting a metric you invented this month because the real one moved the wrong way.
Monthly or Quarterly: Which Cadence?
Monthly for seed and Series A, quarterly only once you have a real board and formal reporting. The trade-off is real, so decide deliberately:
Whichever you choose, fix the date. "First Tuesday" is a commitment anyone can hold you to. "Monthly-ish" is not a cadence.
How Updates Turn Into Your Next Round
The highest-return use of an investor update is sending it to people who have not invested yet. A prospective investor who has watched you post numbers for twelve months is not evaluating a pitch when you open a round — they are confirming a thesis they have already been forming.
Run it as a pipeline, not a mailing list:
This is the same discipline as a sales pipeline, and it fails for the same reason sales pipelines fail: the follow-up stops. GIGABOOST tracks investor conversations through a nine-stage pipeline so the update list and the raise are the same system rather than two spreadsheets. For the broader mechanics, see our guide to investor pipeline management and following up without being annoying.
For founders who have not yet raised and are building the list from scratch, Y Combinator's guide to seed fundraising covers the sequencing, and Crunchbase News and First Round Review are useful for reading how the market is behaving before you time a raise.
Mistakes That Make Investors Stop Reading
Five patterns that reliably kill an update list.
One more, specific to raising: do not hide your runway. Every experienced investor calculates it from your burn anyway, and getting it wrong in their favour is worse than publishing it yourself. If runway is short, say so and say what you are doing — that is precisely the month when a specific ask is most likely to be answered.
Frequently Asked Questions
How long should an investor update be?
One page, or roughly 300 to 500 words, plus the metrics block. The constraint is not politeness — it is that the people most useful to you read on a phone between meetings, and an email that needs scrolling gets archived for later and never reopened. If you have a longer narrative, link it as a separate document and keep the email short.
Should I send updates to investors who passed?
Yes, with their permission, and it is one of the highest-return things you can do. An investor who passed at pre-seed usually passed on stage or evidence, not on you. Twelve months of visible execution answers exactly that objection, and the next round opens with someone who already knows your numbers rather than a cold deck.
Do I have to include cash in bank and runway?
Include both. Any experienced investor will estimate runway from your burn whether you publish it or not, so withholding it buys nothing and signals that something is wrong. Publishing a short runway alongside a clear plan and a specific ask is how founders get bridged; publishing nothing is how they get a surprised phone call.
What if nothing happened this month?
Send it anyway and say so. "Quiet month: shipped the migration, closed no new logos, pipeline up 20%" is a legitimate update and takes ten minutes to write. Skipping a month because the news is thin trains your readers to interpret every silence as a problem, which costs you far more than one unremarkable email.
Should prospective and current investors get the same email?
Most founders send one version to everyone, which is simplest and keeps the content honest. If you do split it, the difference should be narrow — typically detailed cash and runway figures and anything commercially sensitive. Do not write a flattering version for prospects; the gap between the two will eventually be visible to someone who sits on both lists.
The Bottom Line
One page, six blocks, same date every month, bad months included. The update is not reporting overhead — it is the cheapest, most durable fundraising asset you own, because it turns a cold pitch into a thesis someone has already been forming for a year. Start this month, and put the investors who passed on the list.
