Why Use an Investor Update Template?

Hey everyone,

There is no need to reinvent the wheel or investor update structure when you can simply use a template from one of the world’s top VC experts, right?

Investor updates aren’t just bureaucracy - they’re crucial bridges between founders and financial backers. But crafting them from scratch poses a challenge for many. That’s where structured, battle-tested templates come in.

“Using a template lets founders focus on what matters - driving the business - while keeping communication clear and actionable.”

The Y Combinator investor update template has become especially popular thanks to its proven effectiveness for fast-moving startups and iconic alumni like Airbnb, DoorDash, and Dropbox.

Y Combinator Template Overview

Here’s what the YC template usually looks like:

Hey all,

It’s been an awesome, but intense, [summer/fall/winter/spring]. Many things are tracking well, but there are some challenges we could use your help with (more below).

As always, I’ve included charts for our revenue growth, cash on hand, and burn rate.

KPIs
Revenue with Change %: X$, Y% MoM
Cash on Hand: X$
Burn Rate: X$

How You Can Help
We have some problems with [Product Initiative]. We are lacking experience in [X]. Can you recommend a [Mentor/Partner/etc.] to come in and help (this can be a paid coaching position)?

I have been approached by a VC who wants to potentially pre-empt a [Series X]. How do I best deal with this?

We have lost 2 important [customers/potential customers] due to [X]. Can any of you spare some time to talk through our positioning statements and sales process?

I am worried that [key competitor X] has just closed a [$X Round] (see here for more info), how shall we best deal with this (if at all)?

Quick Recap
A quick qualitative recap of how your month went. Be as quick and to the point as possible here. The point is to have your investors read the entire update and offer help.

In our opinion, this is an exemplary template, especially if you want an easy starting point. But, as you’ll see, there are areas that could be further enhanced.

What Works Well

• Brevity: The absence of filler keeps attention focused on KPIs and actionable requests.
• Highlights problems and asks directly - investors instantly know where help is required.
• Designed for founders just getting started: tracks only the essential financials (revenue, cash, burn).
• Easy to customize for your sector, business model, or unique investor needs.
• Provides a repeatable structure for regular updates, building a sense of momentum.

Potential Limitations

• Lacks historical context: The update doesn’t directly tie current challenges to previous business periods. For instance, if a failed campaign last month caused this month’s drop, that chain should be made explicit.
• Minimal metrics: Listing only three KPIs makes updates manageable, but investors often expect more data to understand the full picture (think 7-10 core metrics).
• Opportunity cost: Overly concise reports can mean follow-up questions and extra rounds of clarification with stakeholders.
• Opportunity for growth: Adding a share of the total next to each absolute number (customers lost as a share of all customers, for example) increases clarity for investors.

Which metrics to add as you grow

The three numbers in the YC template (revenue, cash, burn) are the floor. Y Combinator’s own list of metrics investors care about goes further, and most founders add a few of these once they have them:

• MRR or ARR and the month-over-month change, so the trend is visible without a chart.
• Runway in months, next to cash and burn, so nobody has to do the division.
• Customer numbers: active users or paying customers, new and churned this period.
• One efficiency number that matters for your model, such as gross margin or customer acquisition cost.

Pick a handful and keep them the same every month. A metric that appears once and then disappears raises more questions than it answers. A metric that moves the wrong way, explained in one line, builds trust.

Keep it short

The template’s brevity is a feature, not a gap to fill. The Founder Institute and OpStart templates land in the same place as YC’s: a one-sentence summary at the top, the handful of numbers that matter, one highlight, one lowlight, and one specific ask with a copy-and-paste blurb an investor can forward. If the update takes more than a few minutes to read on a phone, cut it. Send it on the same day every month so investors start to expect it.

Recommendations & Conclusion

Overall, the YC Investor Update Template is a fantastic starting point - especially for first-timers or founders worried about breaking the ice.

What’s our advice? Tweak it to match your situation. Include extra KPIs as your company - and stakeholder expectations - mature. Highlight not just what’s challenging, but what caused those challenges. If you missed targets, mention it directly, and connect it to last month’s numbers or events.

Most importantly, don’t be afraid to personalize the structure. Investor relations is, at its core, relationship-building, and clarity here earns trust.

“A template is only as good as its adaptation. Make it work for you by making it yours.”
