The short answer
Send a short update by the 10th of every month: a TL;DR, the same key metrics with month-over-month change, cash and runway, wins, honest challenges, two or three specific asks, and next month's priorities. Send a shorter quarterly version to prospects who asked to be kept posted.
- Send monthly, even in bad months; skipping is what worries investors.
- Report the same metrics every month, including cash and runway for current investors.
- Specific, small asks get answered; vague asks get ignored.
- Send a shorter version to prospects; updates turn 'too early' into a meeting later.
- In a hard month, say it plainly in the TL;DR and share the plan.
- Keep it readable in two minutes on a phone.
Why investor updates matter
A monthly investor update is the cheapest fundraising tool you have. It keeps current investors helpful, turns "too early" into "let's talk," and gives you a written record of progress for your next round. Founders outside the big hubs often have fewer investors on the cap table, which makes each one's help count for more. Updates are how you get it.
Send updates to two lists: current investors (the full version) and prospects who asked to be kept posted (a shorter version without sensitive numbers).
The copyable monthly template
Copy this into an email. Replace everything in [brackets]. It should take 30-45 minutes once a month.

• Revenue or MRR: $[x] / $[y] / [+z%]
• Customers or active users: [x] / [y]
• [One metric that matters most for your business, e.g. pilot conversions, retention, units shipped]
• Cash in bank: $[x] · Monthly net burn: $[y] · Runway: [z] months
Wins
• [Win 1, with a number]
• [Win 2]

Asks
• [Specific intro: "an intro to the head of supply chain at a regional grocery chain"]

Next month's priorities

[Your name]
What to include, section by section
| Section | Purpose | Tips |
|---|---|---|
| Subject line | Gets it opened and searchable later | Same format every month so investors can find past updates |
| TL;DR | Many readers stop here | Lead with the number, then the ask |
| Key metrics | Shows the trend | Same metrics every month; never quietly drop a bad one |
| Cash and runway | Lets investors help before it's urgent | Always include it for current investors |
| Wins | Momentum and credibility | Two or three, each with a number |
| Challenges | Builds trust and invites help | Pair each problem with your plan |
| Asks | Turns readers into helpers | Specific, small, easy to act on |
| Priorities | Sets up next month's accountability | Three items maximum |
| Thanks | Rewards help, encourages more | Name the person and what they did |
Examples of good asks
The ask section is the reason updates pay off. Vague asks get ignored; specific asks get answered. Hypothetical examples:
| Weak ask | Strong ask |
|---|---|
| "Intros to customers" | "An intro to the CFO or revenue-cycle lead at a 200+ bed hospital in Tennessee or Georgia" |
| "Help with hiring" | "Do you know a controls engineer in Cleveland or Columbus who'd consider a startup? Job post: [link]" |
| "Investor intros" | "We open our seed round in March. Who's the one angel or fund you'd introduce us to first? Forwardable blurb below." |
| "Feedback" | "We're choosing between $49 and $99 per seat. If you've priced a B2B product for small businesses, can I have 15 minutes?" |
| "Partnerships" | "Anyone with a contact in purchasing at a national distributor of HVAC parts?" |
For intro asks, attach a forwardable blurb so the investor can act in a minute. See the warm intro playbook.
Cadence: how often and when
- Monthly from your first check through Series A. Send by the 10th of each month.
- Quarterly to prospects who said "keep me posted," and to investors after Series A if your board meets regularly.
- Immediately for big news (a major customer, a key hire, a term sheet) or a serious problem. Bad news travels better from you than from someone else.
- Always, even in a bad month. Skipping a month is what makes investors worry.
A sample update (hypothetical)
Subject: FieldLedger — October 2026 update: first distributor deal, $31K MRR
TL;DR: We signed our first regional distributor, which puts us in front of about 400 contractors. MRR grew 19% to $31K. Our biggest ask: intros to HVAC distributors in Texas.
Metrics (Oct / Sep): MRR $31.2K / $26.2K (+19%) · Paying contractors 142 / 121 · Logo churn 1 / 2 · Cash $612K · Net burn $48K · Runway 12.7 months
Wins: Distributor agreement signed; second engineer started; average contract value up 8% after the new pricing tier.
Challenges: Onboarding takes 9 days on average; we want 3. We're building a guided setup and expect results in December.
Asks: (1) Intros to HVAC or plumbing distributors in Dallas or Houston. (2) A customer success lead with trades experience.
Next month: launch guided setup; sign distributor #2; start seed conversations with three Texas funds.
Thanks to one of our angels for the distributor intro.

The short version for prospects
Prospects get less detail. Leave out cash, burn and anything confidential; keep the momentum and the invitation.
Subject: [Company] — Q[n] [Year] update: [headline]
Hi [First name], you asked me to keep you posted, so here's our quarter in four lines:
• [Headline metric and growth, e.g. "revenue up 2.4x since we met"]
• [Biggest milestone]
• [Team or product news]
• [Round timing: "We plan to raise our seed in [month]."]
If you'd like to catch up before then, just reply. [Your name]
How to write the update in a hard month
Every company has bad months: a lost customer, a delayed launch, a key person leaving. That's when updates matter most. Investors who hear about a problem early can help; investors who discover it later lose trust.
- Say it plainly in the TL;DR. "We lost our largest customer, about 18% of MRR."
- Explain what happened in two sentences, without blaming anyone.
- Share the plan and the date you'll report back.
- Make a specific ask that would help most, such as three replacement prospects or advice from someone who has been through it.
- Update runway if the change affects it, and say what you'll cut if needed.
Format and tools
Plain email works best. Use BCC or a simple newsletter tool so investors don't see each other's addresses, keep formatting light so it reads well on a phone, and save every update in one shared folder. When you raise your next round, those updates become a ready-made record of execution for new investors' diligence.
Using updates to raise your next round
Updates are a quiet fundraising engine. Investors who passed at pre-seed because it was "too early" often invest at seed after watching three to six months of consistent progress. When you meet a prospect who says "keep me posted," ask: "Can I add you to our monthly update?" Then do it.
A few months before you raise, add a line: "We expect to open our seed round in [month]. If you'd like an early look, reply to this email." Then build the rest of your list with how to raise pre-seed without a network and the cold email templates. There's no shortage of possible readers: the Zalarma investor database lists 19,738 US startup investors who include seed among their stages (Zalarma investor database, as of 2026-11-01).
Mistakes to avoid
- Changing which metrics you report when the numbers dip
- Leaving out cash and runway
- Writing an essay; aim for something readable in two minutes
- Asks so broad nobody can act on them
- Sending only when the news is good
- Putting every investor in the "To" field; use BCC or a simple email tool
- Sharing confidential customer names or numbers with prospects who aren't investors
Monthly update checklist
