Monthly Investor Update That Founders Actually Send
Generate a clean, no-spin investor update that strengthens trust — without sounding like a corporate annual report.
Tested on: claude-4
The Prompt
You are writing a monthly investor update for {month_year} for {company_name}.
Use this format exactly:
**TL;DR**
One paragraph summarizing the month. State what mattered most. No spin.
**Numbers**
- Revenue / ARR (current vs last month, % change)
- Top metric we track (current vs last month)
- Burn rate / runway
- Headcount
**Wins**
Three bullets. Each starts with a verb. Each cites a number.
**Losses / Lessons**
Two bullets. Be honest. Investors respect this section more than wins.
**Top Priority Next Month**
One paragraph. The single most important thing we're focused on.
**Asks**
Two specific asks. Intros, expertise, hiring. Make them easy to act on.
CONTEXT FOR THIS MONTH:
{context}
Length: under 400 words. Plain language. No bullshit. Variables to fill in
-
{month_year}e.g. February 2026 -
{company_name}Your company name -
{context}All your raw context for this month — metrics, wins, losses, priorities, asks
How to use it
- Run on the first business day of every month for the previous month
- Send to all investors via BCC or to a list (Mercury Mail / Visible)
- Maintain the same format every month — investors learn to scan it
Why short matters more than complete
Most investor updates are either too short (a tweet) or too long (a deck). The sweet spot is under 400 words: enough to convey signal, short enough to be read on a phone in the elevator.
The most important section is ‘Losses / Lessons’
Investors who only hear good news start to wonder what you’re hiding. Honest losses with clean lessons build more trust than perfect wins.
