Send a short monthly email in a fixed order: TL;DR, the same KPIs every month, highlights, lowlights with the fix, specific asks, cash/burn/runway, shout-outs. Put the substance in the body. An attachment is optional, not required for the story. Visible’s 2026 benchmarks (3.5M+ updates) show monthly as 65% of sends, ahead of quarterly (22%) and weekly (13%). The update keeps investors warm between decision-first board meetings. It is not a substitute for the board pack. Not legal, tax, or investment advice.
Why monthly beats ad hoc
Visible’s 2026 Investor Update Benchmarks cover 3.5M+ updates. Cadence share: monthly 65%, quarterly 22%, weekly 13%. Among founders who send on a regular cadence, 78% report increased investor engagement and zero report a decrease. Ad hoc senders report flat engagement. The top-selected benefits of a regular cadence are accountability (73%) and investor relations (60%).
Warp (Ayush Sharma, 25 Jan 2024, updated July 2026) frames early-stage (pre–Series B) as monthly and later stage as often quarterly. First Round Review / Paul Arnold (published 3 Mar 2015, updated 29 Feb 2024) asks for at least two updates per quarter covering wins, challenges, product, sales/traction, hiring, financials, and needs. That is a floor, not a ceiling, for founders who already ship monthly.
A FounderNexus session made the same operating point: keep the relationship continuous between decision-first board meetings, and do not treat the update as a decision forum. Bad-month consistency matters more than polish.
Fixed section order
| Section | Purpose | Source frame |
|---|---|---|
| TL;DR / exec summary | One screen: what changed, what you need | Warp / YC; Founder Collective TL;DR |
| KPIs (same set every month) | Trend without redefining the metric | Warp metrics minimum; Visible KPIs block 14% of content |
| Highlights | Wins with named evidence | Visible Highlights 23% (most used); Warp highlights |
| Lowlights + fix | What broke and the next step | Visible Lowlights 10% (least used); Warp lowlights; Founder Collective “what I am freaked out about” |
| Asks | Specific intros, hires, customers, advice | Warp: most underused; Visible Asks 11%; Founder Collective “what I need help with”; Arnold wish lists |
| Cash / burn / runway | Liquidity line investors can trust | Warp cash, burn, runway |
| Shout-outs / thank-yous | Name who helped | Warp shout-outs; Founder Collective thank-yous; Arnold thank investors publicly |
| Priorities / what’s next | Near-term focus (optional short block) | Warp priorities; Founder Collective what’s next |
Visible content-block shares on the same report (Highlights 23%, KPIs 14%, Fundraising 12%, Product launches 11%, Team 11%, Asks 11%, Thank you 10%, Lowlights 10%). Highlights are the most used block. Lowlights are the least. Warp’s YC-aligned six core sections are exec summary, metrics, highlights, lowlights, shout-outs, and priorities, with asks called out as most underused. Founder Collective / Micah Rosenbloom (28 Sep 2017) adds fundraising status, learnings, team, “what I feel good about,” and “what I am freaked out about” as fill-in prompts inside that same rhythm.
25% of Visible updates include a chart; among those with charts, the median is 4 charts. 50% include an image. Charts help when the KPI table needs a trend line. They do not replace the fixed section order.
Metrics that belong every month
| Metric | Why it belongs | Sibling |
|---|---|---|
| ARR / MRR + MoM | Top-line trend in one line | Finance hub |
| NRR or churn | Retention without a surprise at the board | NRR vs GRR |
| Cash | Absolute liquidity | Runway calculator |
| Burn | Net cash burn for the period | Burn multiple vs Rule of 40 |
| Runway | Months of cash at current burn | Runway calculator |
| Headcount / customers | Scale context beside revenue | Optional; keep definitions stable |
Warp’s minimum is Revenue MRR/ARR + MoM, NRR or churn, cash, burn, and runway. Add headcount or customer count when your board already tracks them. Do not invent a new KPI for a good month and drop it the next. If you change a definition, say so in the TL;DR and restate the prior month on the new rule.
Cadence, list, and send habits
Visible open rates by audience: Board 78%, Current investors 77%, Team 77%, Advisors 75%, Family & friends 71%, Prospective investors 64%. Median open rate across the platform is 77%. Open rate by list size (main “How many recipients” table): 1–5 recipients 100%; 6–15 83%; 16–30 79%; 31–50 77%; 50+ 69%.
Send timing on Visible: Monday is 20% of sends; Friday is 19%. Friday and Wednesday show the highest median open rates. 26% of updates land in the first 7 days of the month; 17% after the 25th; the 1st is the most popular send date. Warp: send yourself (CEO), pick a date and stick to it, and send in bad times. Keep the update in the email body, under two minutes to read; most great updates are 200–400 words plus a metrics table.
Put prospective investors on a separate list from current investors and the board. Visible’s prospect open rate (64%) sits below current investors (77%). Mixing lists blurs who is already on the cap table and who is still in process. Y Combinator’s Investor Update template is the most-used template on Visible.

Mistakes that burn trust
Skipping bad months. Warp: it is more important to send in bad times. Arnold: stay transparent in hard months, not only when the chart looks good. Visible’s regular-cadence founders report engagement up; ad hoc senders report flat.
Hiding lowlights. Lowlights are the least-used Visible block (10%). Put the miss and the fix in the same bullet.
Vague asks. “Any intros?” wastes the list. Arnold wants specific named prospects and open roles. Warp flags asks as the most underused section.
Redefining KPIs month to month. Investors compare rows. Match the board pack definitions.
Attachments as the only substance. Warp: keep the update in the body. A deck can sit behind a link; the email should stand alone in under two minutes.
Mixing prospects into the investor list. Prospect open rates are lower (64% vs 77% for current investors on Visible). Separate lists keep fundraising status honest.
Treating the update as a board meeting. Updates are not decisions (FounderNexus session). Hard votes and strategy belong in the pack and the room.
Monthly investor update lock
Monthly investor update lock
- Pick a permanent send date. Visible’s 1st is the most popular day. Warp: stick to it.
- Freeze the KPI set. ARR/MRR + MoM, NRR or churn, cash, burn, runway (Warp). Write definitions once with the finance hub.
- Draft TL;DR last. Write highlights, lowlights, and asks first, then compress to two sentences.
- Write lowlights with a fix. Miss + owner + date in one bullet. Do not bury the miss in a soft paragraph.
- Make asks specific. Named intros, open roles, one decision you want advice on (Arnold; Warp).
- Separate lists. Current investors and board on one list; prospects on another (Visible open-rate gap).
- CEO sends from the body. Under two minutes; 200–400 words plus the metrics table (Warp). Optional chart or image (Visible: 25% include a chart; 50% an image).
- Send in bad months too. Regular cadence shows engagement up (78% of Visible regular senders); ad hoc is flat.
- Do not turn the reply thread into a board. Park decisions for the next Series A board meeting.
Monthly email vs the board pack
Board meetings run every 6–8 weeks for about 2–3 hours on a decision-first pack (how to run a Series A board meeting). The monthly update sits between those meetings. Same KPI definitions, shorter form, no consent agenda, no closed session. A FounderNexus session put it as: updates are not decisions. Use the email to keep the relationship continuous. Use the board pack when you need a vote, a hire, a raise posture, or a strategy call.
