Monthly Investor Update

Subject: [Company] update, [Month Year]

Dear all,

The month in one paragraph

Two or three sentences. What changed, what did not, and the one thing you most want a reader to take away. If the month was bad, it is bad here rather than in paragraph four.

The numbers

Every figure on one definition, per Metric Definitions. Prior month, and the same month last year where you have it.

	This month	Prior month	Change
Revenue
Customers
[Your one carrying metric]
Cash
Net burn
Runway

If any definition changed this month, one line naming the metric, the change, and whether the table above was restated.

The ask

One ask, specific enough that a reader knows in five seconds whether they can help.

Last month you asked for [ask]. [What came back, or that nothing did.] Carried forward or closed.

An investor does not read your update. They read it next to the last one. Which means the number that decides how your month reads is not this month's, it is last month's, and whether the two were counted the same way. Every template in circulation is the email body, which carries nothing between months. This pack is the two files that do: a definition register that pins each metric to what your report actually computes, and a restated trend built on it.

Torval, a fictional workforce-scheduling company, sent ten updates in fourteen months. Month 8 reported 240 customers: 196 paid accounts plus 44 trials, from the CRM. Month 14 reported 214, paid only, from billing, assembled by a new hire. Held constant either way, Torval grew 9.2 percent across those months. What eleven investors received was a fall of 26 customers and 10.8 percent. The SEC's guidance on performance metrics asks a filer who changes a metric's method to disclose the effect on amounts already reported.

The other half is the ask, the only line that asks a reader to do something and the only one nobody tracks. Torval made 14 asks. The 4 that named a company, a person or a decision were answered; the 10 that named a category were not. Investor Register also holds what your financing documents already require, which most founders have not read since signing. The NVCA model Investors' Rights Agreement puts quarterly statements at 45 days and audited annual statements at 180. The board meeting pack reads the same pinned definitions.

Every document in the pack

Metric Definitions, the restated Metric Trend, the Ask and Follow-up Tracker, and the update itself.

Metric DefinitionsMetric TrendAsk TrackerThe Update

Metric Definitions

Torval Systems. A metric with a blank field does not go in the update.

Customers

Definition as computed: Accounts with a non-cancelled paid subscription on the last calendar day of the month
Counted per: Billing account, not parent logo
Source: Billing system, monthly subscriber export
Excludes: Active trials, two internal accounts, one design partner paying nothing
Definition last changed: M14, restated back to M2

Runway

Definition as computed: Cash divided by trailing three-month average net burn, rounded down
Source: Bank statement and bookkeeping monthly summary
Definition last changed: Never

Runway of 10 means $1,291,000 over a $122,333 average. The inputs travel with the number.

Metric Trend

Customers, restated on paid accounts only, against what each update actually said.

Month	Pinned	As reported	Same
M2	118	144	No
M5	152	187	No
M8	196	240	No
M11	205	no update	Gap
M14	214	214	Yes

M8 to M14 on paid accounts: 196 to 214, up 9.2%
M8 to M14 on paid plus trials: 240 to 262, up 9.2%
M8 to M14 as actually sent: 240 to 214, down 10.8%

Both consistent definitions agree with each other. The series the investors have agrees with neither.

Ask Tracker

Ask and Follow-up Tracker

14 asks across 10 updates. Four were answered.

Ask	Named	Chased	Outcome
A-03 Dispatch lead at Kessler Freight	Company	2 investors	Pilot, M5
A-04 Senior backend engineers	Category	None	Nothing
A-09 Marketplace pricing reference call	Decision	3 investors	2 calls, M8
A-11 Operations lead at Harrow Distribution	Company	1 investor	Customer, M12
A-12 VP Engineering signal	Category	None	Nothing

Torval update, month 15

Dear all,

Paid customers reached 218 and revenue $98,900, both up modestly. The larger news is housekeeping: our customer count had been reported on two different bases, and the whole series is restated below.

	This month	Prior month	Change
Revenue	$98,900	$96,400	+2.6%
Paid customers	218	214	+4
Cash	$1,291,000	$1,412,000	−$121,000
Net burn	$121,000	$118,000	+$3,000
Runway	10 months	11 months	−1

Customers is now paid accounts only. Earlier updates mixed paid with active trials, so the series is restated to month 2 and attached.

The ask

An introduction to whoever runs scheduling at Bramley Cold Chain. I am asking four of you individually this week.

Last month I asked for VP Engineering leads. Nothing came back, I am closing that ask and running a search instead.

What's in the pack

Monthly Investor Update

The email itself, under 400 words: the month in a paragraph, the numbers table, what went well, what did not, one ask, and next month.

Metric Definitions

One entry per reported metric, holding the definition as computed, the source report, the exclusions, and the date it last changed.

How a Metric Stays Comparable

The four-minute method behind the rest of the pack, including how to change a definition without breaking the series it sits in.

The Ask

What makes an ask answerable, which asks get replies and which never do, and the sentence that closes out last month's.

Metric Trend sheet

Every month on the pinned definition, with what was actually reported at the time in a second block wherever the two disagree.

Definition Change Log

One row per definition change: old, new, the reason, the month it takes effect, and whether prior months were restated.

Ask and Follow-up Tracker

One row per ask, whether it named something specific, who chased it, what came back, and whether it is closed.

Investor Register

Who receives the update, what they hold, what they have actually helped with, and the reporting clause each of them can enforce.

How to use it

1
Open in River, or download it
Open the pack in River and let the agent fill it in, or download the blank Word and CSV files instantly with no account.
2
Send the updates you already sent
River reads every one of them oldest first, extracts each number with the month it was reported in, and lists every ask and what came back.
3
Pin the definitions and restate
Each metric gets tied to what its report actually computes, then the full history is recomputed from source on that one definition.
4
Draft this month, then close last month's ask
The update is assembled from figures that already exist, and it opens the new ask only after the previous one has a recorded outcome.

Frequently asked questions

Is this template free?

Yes. The whole pack downloads as Word documents and CSV sheets with no signup and no credit card. "Edit with AI" is a separate, optional path for founders who want the agent to read their past updates and fill the sheets in. The rest of the packs are in the template library.

What format are the downloaded files?

Word documents (.docx) for the update, the definitions and the two method documents, and CSV (.csv) for the four sheets, zipped together. They open natively in Word, Pages, Google Docs, Excel, Numbers and Sheets, with nothing to convert. In River the same content opens as live Docs and Sheets.

What does 'Edit with AI' actually do?

It creates a free River account and installs this exact pack as a private workspace. The agent opens ready to read whatever you send: past updates, a billing export, bank statements, a CRM list. It pins the definitions and restates the trend before drafting anything. Nothing is written until you send it something.

How is this different from an investor update template on a blog?

Those are the email body, and almost all of them tell you to keep the same metrics every month. None of them carries the file that makes that true. This pack pins each metric to the report that computes it, logs every change, and keeps the restated series next to what you actually sent.

Does it calculate my metrics for me?

No. It transcribes them from the systems that already produce them and records where each one came from, which is what makes two months comparable. Finance teams building the exhibit that goes underneath an update use investor update financials instead. A one-off list from a single holder, arriving outside the cadence with a date on it, is an investor data request response.

What about a brand-new board member, do they need something different?

Yes. A first monthly update assumes the reader already knows the company; a new director or advisor does not. The board member and advisor onboarding pack builds their orientation brief and expectations note from your own board minutes, separate from what a recurring update covers.

Who is this template for?

Founders who have already raised and now owe a recurring update to people who own part of the company. It suits a startup workspace at seed and Series A. If you are still working out what you signed, the SAFE and note conversion model covers the instruments themselves. If the last one went out months ago, an investor update backfill closes the gap first.
