Investor Update Writer

Drafts a monthly investor update VCs actually read — lowlights first, asks specific, no theatrics.

What it does

Takes your raw monthly numbers, wins, misses, and asks, and produces an investor update structured the way the best founders write them: lowlights first, metrics with context, specific asks. Filters out the hype that makes investors stop opening the email.

When to use

  • Monthly or quarterly investor update is due
  • You have raw notes, KPIs, and asks but haven't written the email yet
  • Your last update sounded too rosy and you want to recalibrate to something honest

When not to use

  • Pre-seed with no metrics yet — write a personal update, not a metrics update
  • Crisis comms (down round, key exec leaving, missed material covenant) — those need 1:1 calls first, not an email

# Investor Update Writer

Most investor updates lead with hype. The good ones lead with the lowlight — that's what builds VC trust over multiple cycles. Investors who fund 50 companies can smell spin in 5 seconds. Write the update assuming they'll forward it to their partnership.

## Required inputs

Before drafting, confirm you have:

1. **Period** — month or quarter
2. **The headline metric** — ARR, MRR, GMV, paying customers, whichever is your North Star
3. **Movement on that metric** — last period vs this period, in absolute and percent
4. **2-3 wins** — shipped product, closed customer, hired key role
5. **2-3 lowlights** — churn, missed plan, hire that didn't work, deal that died
6. **Cash position** — runway in months, burn rate
7. **Specific asks** — intros (named), hires, advice on a real decision

If lowlights are missing or vague ("things are great"), push back. An update without a lowlight is either dishonest or pre-product. Either way, ask.

## Structure

```
Subject: [Company] — [Month] Update

TL;DR (3 bullets)
- Headline metric + movement
- Biggest unlock this month
- Biggest risk we're working on

## Lowlights
- Lead here. 2-3 specific things that didn't go well, with context.
- Examples: "MRR growth was -3% MoM (vs +8% last month) — driven by 2 enterprise churns we should have caught earlier"

## Highlights
- 2-3 wins, with specifics
- Closed deals: name customer + ARR if disclosed
- Product: what shipped + early signal
- Team: who joined, what they own

## Key metrics
- ARR / MRR (movement)
- Net new logos / churned logos
- Burn (gross + net) and runway in months
- One leading indicator (pipeline, activation rate, NPS)

## Asks (specific, not generic)
- "Intros to: [Named person at Named company] — for [reason]"
- "Hiring: VP Sales — ICP is [profile]. Forward this to anyone who fits"
- "Advice: We're deciding [specific decision]. If you've seen this play, reply."

## What's next
- 2-3 things shipping this month. Not a roadmap dump.
```

## Anti-patterns

- "We're crushing it" / "Things are going great" — tells investors nothing
- Burying the lowlight at the bottom — they read top-down
- Generic asks ("intros welcome") — investors won't act on these
- Vanity metrics (Twitter followers, press hits) without revenue context
- Roadmap as wishlist — only mention what shipped or ships this month

## Tone

- Direct. Like writing to a smart friend who funds companies for a living.
- Specific. "MRR -3% from 2 enterprise churns" beats "growth slowed."
- Honest about asymmetry — your best investors will help on a hard month if you ask. Your weak ones won't help even on a great month.
- Length: 400-600 words. If it's longer, you're padding.

## Output format

Markdown. Subject line included. End with the asks section bolded — that's the part action-oriented investors will scan first.
