Investor relations for startups: keeping investors warm
Investor relations for startups means keeping current and future investors informed and on your side between rounds, so they help when you need them. Send existing investors a short monthly update with numbers, wins, lowlights and one specific ask. Keep a separate list of prospects and investors who passed, and send them a brief quarterly note. Consistency matters more than polish.
Most founders only talk to investors when they are raising. That is backwards. The investors who write checks fast, lead follow-ons and make real intros are the ones who watched you execute for months before you asked. A steady update habit turns your cap table into a working team and your next raise into a shorter conversation.
This playbook splits your investor relationships into tiers, gives each one a cadence and a channel, and lays out a 12-month plan. You also get ready-to-send messages for the moments that matter: the monthly update, bad news, a pre-raise heads-up and keeping warm with investors who passed. Set it up once, then run it in under 30 minutes a week.

Who to contact and how often
| Tier | Who | How often | Channel | What to send |
|---|---|---|---|---|
| Board and lead investors | Your lead investor, board members and any investor with a board observer seat or major pro rata rights. | Weekly or every other week informally, plus a formal board meeting each quarter. | Short calls or texts between meetings, a board deck before each meeting, and the monthly update email. | Early warning on problems, hiring and budget decisions, runway changes and specific asks for help. They should never learn bad news from the monthly update. |
| Existing investors on the cap table | Angels, smaller funds, syndicate leads and advisors with equity who are not on the board. | Monthly, on the same day each month. | One investor update email to the whole group, plus a personal note to anyone who replies. | Key metrics (revenue or MRR, burn, runway), highlights, lowlights, what you learned, and one or two specific asks such as intros or hiring help. |
| Prospective investors for the next round | Funds and angels you have met who said some version of "keep me posted," plus investors you want to meet before you raise. | Quarterly, more often in the two to three months before a raise. | A short personal email, not the full investor update. | Two or three proof points since you last spoke, a clear sense of momentum, and a light note about timing when a raise is coming. |
| Passed investors and dormant ties | Investors who passed on a past round, former angels you lost touch with, and investors you met years ago. | Twice a year, or when you hit a milestone that addresses the reason they passed. | Personal email or LinkedIn message. | A brief note on what changed, especially the concern they raised. Levin, Walter and Murnighan (2011, Organization Science) found that reconnecting with dormant contacts produced advice that compared favorably with advice from current contacts, so these ties are worth reviving. |
| Connectors and other founders | Founders in your investors' portfolios, scouts, accelerator peers, operators and advisors who know investors. | Every one to two months with a light touch, and right after they help you. | Text, LinkedIn message or a quick coffee. | Thanks, small wins, help on their problems, and a clear, easy ask when you need an intro. Granovetter (1973, American Journal of Sociology) showed weaker ties often carry new information your close circle does not have. |
The 12-month plan
| When | Focus | Actions |
|---|---|---|
| Months 1 to 3: Set up | Build your investor list and start the monthly update habit. | List every investor on the cap table and every prospect who said "keep me posted." Tag each by tier. Pick a fixed send date for the monthly update and a standard metrics block. Send your first update. Schedule quarterly board meetings for the year. Book a short call with your lead investor to agree on what they want to hear between meetings. |
| Months 4 to 6: Deepen the cap table | Turn existing investors into active helpers. | Keep the monthly update on schedule. Add one specific ask each month and thank anyone who helps by name in the next update. Hold one-on-one calls with your five most engaged angels. Send prospects a quarterly note with two proof points. Ask your lead which investors they would want in the next round. |
| Months 7 to 9: Warm the pipeline | Get the next round's investors watching you execute. | Rank prospects by fit and stage. Send each a personal quarterly note. Reach out to passed investors with what changed since they said no. Ask existing investors and portfolio founders for warm intros to two or three target funds. Clean up your data room and update your metrics history so it is ready when someone asks. |
| Months 10 to 12: Prepare to raise or extend | Make the raise feel like a continuation, not a cold start. | Agree on round timing and size with your board. Send a pre-raise heads-up to top prospects. Ask existing investors about pro rata interest. Keep the monthly update going even while fundraising. Review the year: who replied, who helped, who went quiet, and adjust tiers for next year. |

Everyone on a rhythm. Who is due, and when. Recorded in the app on a demo account.
1. Monthly investor update
Subject: [Company] update, [Month]: [one-line headline]
Why it works: A fixed format with real numbers and specific asks builds trust and gets investors to act.
2. Bad news to lead investor before the update
Why it works: Leads who hear bad news early, with a plan, stay supportive; leads who are surprised stop trusting the numbers.
3. Keep-me-posted prospect, quarterly note
Subject: [Company]: quick update since we spoke
Why it works: A short, no-ask note shows momentum over time, which is what prospects want to see before they commit.
4. Reconnecting with an investor who passed
Subject: You were right about [concern], here is what changed
Why it works: Naming their exact objection shows you listened and gives them a real reason to look again.
5. Pre-raise heads-up
Subject: [Company]: planning our [round] for [month]
Why it works: Early access makes warm prospects feel like insiders and helps you build momentum before the round opens.
6. Specific intro ask to an existing investor
Subject: Intro to [Target Name] at [Firm]?
Why it works: A forwardable blurb removes the work from the introducer, which makes the intro far more likely to happen.
7. Thank you after an investor helped
Why it works: Closing the loop quickly tells investors their help mattered and makes them more likely to help again.

The weekly routine
- Monday (5 minutes): Jot down this week's wins, losses and numbers in a running doc so the monthly update writes itself.
- Scan your investor list (5 minutes): pick two people from the prospect or passed tiers who are due for a note.
- Send those two notes (10 minutes): use the quarterly or reconnect template and add one personal detail.
- Close loops (5 minutes): thank anyone who made an intro or gave advice, and log the outcome.
- Check in with your lead (5 minutes): send a quick text or email if anything material changed this week.
Mistakes to avoid
- Only contacting investors when you are raising, which makes every outreach feel like an ask.
- Skipping the update in a bad month, which signals trouble louder than the bad news would.
- Sending vanity metrics without burn and runway, so investors cannot judge the real picture.
- Ending updates without a specific ask, which wastes the help your investors are willing to give.
- Letting your lead investor learn about problems from the group update instead of from you first.
- Forgetting investors who passed, even though many will look again once the reason they passed is fixed.
What to track
- Whether each monthly update went out on schedule.
- Who replies to updates and who acts on your asks.
- Intros made, by which investor, and what came of each one.
- Last contact date for every prospect and passed investor.
- Each prospect's stated concern or reason for passing, and whether you have addressed it.
- Pro rata interest from existing investors ahead of the next round.

Frequently asked questions
What is the 80/20 rule for startups?
The 80/20 rule says a small share of your efforts drives most of your results. In investor relations, that usually means a handful of investors make most of your intros and follow-on decisions. Find those people, give them more of your time and earlier information, and keep everyone else informed through a consistent monthly update.
How do I get investors for my start-up?
Start with warm intros, then keep investors watching you execute before you ask. Ask existing angels, advisors and portfolio founders for introductions to funds that fit your stage. After a first meeting, send short quarterly notes with proof points. When you raise, those investors already know your story. Check with counsel about how you share fundraising details publicly.
How often should a startup send investor updates?
Monthly works for most early-stage startups, sent on the same day each month. Monthly is frequent enough to show momentum and short enough to stay readable. Later-stage companies sometimes move to quarterly. Board members and your lead investor should hear from you more often, and immediately when something material changes.
What should an investor update email include?
Include a one-line summary, key metrics, highlights, lowlights and specific asks. Metrics should cover revenue or MRR, burn and runway, plus one product or usage number. Be honest about what went wrong and what you are doing about it. End with one or two clear asks and a thank you to anyone who helped last month.
Should I keep updating investors who passed?
Yes, as long as they did not ask you to stop. A pass is often about timing or one specific concern. Reach out when you have fixed that concern. Levin, Walter and Murnighan (2011, Organization Science) found reconnecting with dormant contacts produced advice that compared favorably with advice from current contacts, so these relationships still have value.
Do I need a CRM for startup fundraising?
It helps once you are talking to more than a handful of investors. A CRM for startup fundraising tracks each investor, who introduced you, your last contact and the next step. A spreadsheet works fine for a first raise. What matters is that you update it after every call. Then use it to plan your monthly updates and quarterly notes.
