What to include in an investor update

A monthly investor update needs four metrics — MRR, net burn, cash on hand, and runway — three narrative sections covering what won, what’s hard, and what you need, and exactly one ask. Everything else is optional, and most of it should be cut. This guide covers each piece, what to leave out, and the completeness check to run before sending.

The inventory is short on purpose: an update competes for about two minutes of partial attention, and every extra section taxes the ones that matter. The worked numbers below belong to the fictional seed-stage company used across these guides — its April: $42,180 of MRR, $38,400 of net burn, $608,000 in the bank, 14.2 months of runway.

The four metrics

Four numbers, in the same order every month, because together they answer the two questions behind every investor read-through: is it working, and how long can you keep going. MRR answers the first; the other three answer the second.

• MRR, or your revenue equivalent.What customers pay you on a recurring monthly basis, stated with its growth rate — $42,180, up 12.4%, says more than either number alone. It’s the first thing every reader looks for.
• Net burn. Cash out minus cash in — what the company actually lost this month. In an update, burn always means net burn; gross burn is a different number with a different job, and gross vs net burn walks through the split.
• Cash on hand. The bank balance at month end. This is the number investors quietly sanity-check the other three against, and the one they remember between updates.
• Runway. Months until zero cash on your current trajectory — the simple version is cash divided by net burn. Report it to one decimal, and make sure it holds up: the free runway calculator checks the number in thirty seconds, no signup.

Two rules keep the block trustworthy. Definitions are frozen: if burn means net burn in your first update it means net burn forever, and any change gets announced in the update itself, never made silently. And the numbers must agree with each other — if the runway you report doesn’t follow from the cash and burn beside it, say why in one clause. Planned hires change the math; an unexplained gap changes how every other number gets read.

The three narrative sections

The numbers say what happened; three short sections say what it means. Each is two or three sentences, and each has exactly one job.

What won.The best true thing that happened, with a number attached. “Closed Acme at $18k ACV — the first customer sourced entirely from outbound” beats a paragraph of momentum language, because it describes a repeatable system instead of an event.

What’s hard.The number moving the wrong way, named plainly, with the plan next to it. The sample company’s version: CAC at $410 against a $340 target, and paid spend trimmed until the outbound math proves out. This section is what makes the rest of the update believable — and when the hard thing is the whole story of the month, sharing bad news with investors covers how the same format carries it.

What we need.One ask, bounded and specific enough to answer in a single email — “two warm intros to seed-stage CFOs who run monthly reporting,” not “intros appreciated.” An update without an ask wastes the medium: it arrives in the inboxes of people who signed up to help.

These three sit inside a larger frame — a headline, a what-changed line, a closing — and the section-by-section reasoning lives in how to write an investor update. If you want the skeleton rather than the argument, take the two-minute template.

What to leave out

Most weak updates aren’t missing anything — they’re carrying too much. The usual freight:

• Vanity metrics. Cumulative signups, total downloads, lifetime page views. A number that can only go up carries no information about the month, and every investor knows it.
• Press-mention padding. A coverage list says the company got written about, not that it worked. If the press drove signups, report the signups.
• Charts that only go up. The cumulative-revenue curve is the chart version of a vanity metric. If you include a chart, make it one that could have gone down.
• Org-chart trivia.Title changes, reporting lines, the new office. Hiring belongs in the update when it’s a need or a cost, not as news in itself.
• Anything you wouldn’t want quoted back in diligence. An update is a written record. Projections stated as fact, customer names still under NDA, promises about the next raise — every line should survive being read aloud to you a year from now.

When to add a section

Sparingly, and only when the addition has a number attached. Two additions earn their place most often. A hiring section when you’re actively recruiting — your investors’ networks are usually your best sourcing channel, and a standing “we’re hiring a founding engineer” line is a legitimate second ask. And a product milestone when you can state it as a measurement rather than an announcement: the activation rate after the launch, not the launch.

The test for any extra section: if it can’t earn its keep for three consecutive months, it wasn’t a section — it was a paragraph for “what won.”

The completeness check

Thirty seconds against this list before every send:

1. All four metrics present — MRR, net burn, cash on hand, runway — with definitions identical to last month’s.
2. Burn is net burn, and labeled that way.
3. Runway follows from the cash and burn you just reported, or one clause says why not.
4. One win with a number in it.
5. The hard thing named with its number, not around it.
6. Exactly one ask, answerable in a single email.
7. Nothing you’d flinch at hearing quoted back in a year.
8. Total read time under two minutes.
