Cold Outreach to Co-Founders and Advisors: Messages That Get Replies
The short answer
A founder outreach message that gets replies has five parts: one specific reason you chose this person, two sentences of problem in their vocabulary, evidence that the company is real, a small ask of twenty-five minutes, and a visible way to decline. Do not mention equity or a co-founder role in the first message.
Key takeaways
- The first message sells a conversation, not a company. Any ask larger than twenty-five minutes reduces the reply rate rather than raising it.
- Specificity is the whole game. One line proving you read their work outperforms three paragraphs of vision.
- Never open with an equity number or an advisory offer. Both convert a peer conversation into a transaction before there is any basis for one.
- Expect 30-45% replies at fifteen individually written messages, and under 10% at a hundred templated ones. Volume actively harms this channel.
- The follow-up that works is not a reminder. It is a new piece of information.
Founders write two kinds of cold message. The first is a paragraph of vision ending in an invitation to join a journey. The second is a recruiter template with the founder's name pasted at the bottom. Both have reply rates in the low single digits, for the same underlying reason: neither gives the reader a concrete reason to spend the next twenty minutes on you specifically.
This article is about the third kind. The templates below are written for founder-to-peer contact, where you have no authority, no budget and no brand, and where the only asset you have is that you did your homework.
What a first message has to do
Understand what you are actually asking. A stranger is deciding, in about four seconds, whether replying to you is likely to be worth twenty-five minutes. They are not evaluating your company. They are evaluating the probability that this conversation is interesting.
| Element | Length | Job it does |
|---|---|---|
| Why them, specifically | One sentence | Proves this is not a template and that you read their actual work |
| The problem | Two sentences | Gives them something to have an opinion about, in their own vocabulary |
| Evidence it is real | One sentence | Separates you from the large population of people with an idea |
| The ask | One sentence | Small, specific, time-boxed. Twenty-five minutes, not a meeting |
| The exit | One sentence | Removes the social cost of declining, which paradoxically raises the reply rate |
Total length: 90 to 130 words. Anything longer is read as a pitch and skimmed. Anything shorter usually fails to establish why you chose this person.
Co-founder outreach templates
Template 1: technical co-founder, evidence from their public work
Hi Anna,
I read your post about splitting the payments ledger without downtime — the part about
reconciliation during the cutover is exactly the problem I am staring at.
I am building tooling for mid-market European banks to evidence transaction controls
to their auditors. Four compliance leads have told me their current process is a
quarterly spreadsheet exercise, and two have signed letters of intent for a pilot.
Would you have 25 minutes in the next couple of weeks to tell me where you think this
gets hard technically? I am not looking for free consulting — I want to know whether
the constraints I have mapped are the real ones.
If the timing is wrong, a pointer to someone who has done this would be just as useful.
LarsNote what is absent. No mention of a co-founder role, no equity, no deck, no vision paragraph. The ask is an opinion, which is the one thing experts are consistently willing to give strangers.
Template 2: the person has no public writing, only a career history
Hi Marek,
You were the third engineer at Nordwell and stayed through to about forty people, which
is exactly the stretch I am trying to understand — building fast while a regulator is
reading over your shoulder.
I am working on control-evidence tooling for banks. Two signed pilots, no engineer yet.
My open question is how much of the architecture you have to get right in month one
versus what you can defer without paying for it later.
Any chance of 25 minutes? Happy to work around your time zone.
If you are not the right person for this, I would take a name instead.
LarsTemplate 3: warm introduction request, sent to the intermediary
Hi Jonas,
Would you be willing to introduce me to Sofia Lindqvist? I am looking for a technical
co-founder for a compliance tooling company and her work at Kaskad is the closest match
I have found.
Forwardable paragraph below so you can decide without a call.
--
I am building tooling that lets mid-market banks evidence transaction controls to their
auditors continuously rather than quarterly. Two signed pilot letters, no engineer yet.
I am looking for someone who has shipped into a bank security review before. I would
like 25 minutes to test whether the technical constraints I have mapped are real ones.
--
No obligation at all if you would rather not.
LarsThe forwardable paragraph is the whole technique. Asking someone for an introduction and making them write it is a request for twenty minutes of their work. Writing it for them makes it a fifteen-second decision.
Advisor outreach templates
Advisor outreach is easier than co-founder outreach and founders make it harder than it needs to be by asking for the advisory role up front. The correct first ask is a question. The advisory relationship, if it happens at all, forms around the third conversation.
Template 4: functional operator, one specific decision
Hi Priya,
You took Vellum from self-serve to enterprise contracts in about eighteen months, which
is the decision sitting in front of me right now.
We are at 40k monthly revenue, all self-serve, and three inbound requests for annual
contracts with security reviews attached. I cannot tell whether taking them is the start
of the transition or a distraction that breaks the self-serve motion.
Could I have 25 minutes to hear how you sequenced it and what you would do differently?
If you would rather not, no problem at all — I appreciate the question is a real one.
LarsTemplate 5: customer-side insider
Hi Dr Halvorsen,
You have run procurement at Vestland Hospital Trust for six years, so you have almost
certainly rejected products like the one I am building.
We are building scheduling software for surgical teams. I have spoken to eleven surgeons
and zero procurement leads, which I now think is the wrong way round.
Would you be willing to spend 20 minutes telling me what makes a product like this
un-buyable? I am happy to pay your standard consulting rate for the time, and I am not
going to pitch you.
LarsTwo deliberate choices here. Offering to pay makes the request legitimate rather than a favour, and it is often the only way a currently employed buyer can accept the conversation. And saying explicitly that you will not pitch removes the main reason such people decline.
Template 6: the follow-up that converts a call into a relationship
Hi Priya,
Following up on our conversation three weeks ago. You said to take the enterprise
contracts but to hold the self-serve pricing rather than negotiating custom rates.
We took two of the three, kept list pricing, and lost the third on exactly the grounds
you predicted. Net revenue is up 30% and the self-serve funnel is unchanged.
Thank you — that was a decision I would have got wrong.
One more if you have the patience: we now need a security questionnaire process and I
have no idea what good looks like. Worth 20 minutes?
LarsThis is the message almost nobody sends, and it is the single highest-converting message in the entire sequence. People who advise strangers rarely find out what happened. Telling them makes you memorable, and it makes the second ask trivially easy to accept.
Template 7: formalising the advisory relationship
Hi Priya,
Three conversations in, and each one has changed a decision. I would like to make this
a formal advisory arrangement if you are open to it.
What I would want: one 45-minute call a month, plus the occasional question by email.
Two-year term, either of us can stop with 30 days' notice.
What I propose in return: 0.4% in options, vesting monthly over two years with a
three-month cliff. Standard FAST-style agreement, happy to use your lawyer's version.
Entirely fine to say no and keep talking informally.
LarsThe terms here follow the structure set out in Startup advisor equity. Stating the commitment in hours before stating the equity is deliberate: it makes the grant look derived rather than arbitrary, which is exactly what it should be.
Template 8: the re-approach, three months later
Hi Anna,
I wrote to you in March about compliance tooling for banks. You did not reply, which is
entirely fair — I did not have much to show at that point.
Since then: two pilots live, one paying, and a specific technical problem I keep failing
to solve well. If the earlier timing was the issue rather than the idea, I would still
value 25 minutes.
If not, I will stop writing — no hard feelings either way.
LarsFollow-up sequencing
Founders either never follow up or follow up like a sales sequence. Both are wrong. The rule for peer outreach is that a follow-up must contain new information, not a reminder that you exist.
| Touch | Timing | Content | Stop condition |
|---|---|---|---|
| 1 | Day 0 | The first message | n/a |
| 2 | Day 7-9 | One new fact: a pilot signed, a technical finding, something they would find interesting | Any reply, including a decline |
| 3 | Day 21-25 | A short, genuine close: I will stop here, happy to be pointed elsewhere | Always the last touch in this cycle |
| 4 | Month 3+ | Only if something material has changed. Acknowledge the earlier silence | Two full cycles with no reply means stop permanently |
Three touches, then stop. The names on a founder-level shortlist are finite and often overlapping with your future investors, customers and hires. Burning them for one extra percentage point of reply rate is a bad trade.
What reply rates to expect
These are my working estimates for founder-written outreach to senior people, and they assume the message structure above. They are not a benchmark study; measure your own after twenty sends and use those instead.
| Approach | Volume | Estimated reply rate | Call conversion |
|---|---|---|---|
| Individually written, specific evidence, small ask | 10-20 | 35-45% | about 50% |
| Personalised opening line on a template body | 50-100 | 10-15% | about 30% |
| Fully templated | 200+ | 2-5% | under 20% |
| Warm introduction with a forwardable paragraph | 5-10 | 60-75% | about 70% |
| Re-approach after three months with new evidence | 10-20 | 20-30% | about 50% |
The commercial logic is clear once the numbers are laid out. Fifteen individually written messages produce roughly six replies and three calls. Two hundred templated messages produce roughly eight replies and one and a half calls, cost far more time in aggregate, and burn two hundred names. For founder-level search, volume is not the lever.
Channel notes
- Email beats platform messaging when you can find the address, because it is not competing with recruiter volume in the same inbox.
- A connection request with a note is constrained in length, which forces the discipline of a single specific line. That constraint often helps.
- Do not send a voice note or a video to a stranger. It asks for more of their attention than a first contact has earned.
- Do not contact people on three channels simultaneously. It reads as pressure, and experienced people notice.
- Send on Tuesday to Thursday morning in their time zone. A small effect, but free.
- Reply within a day when someone does answer. The single most common way founders lose a promising thread is a four-day gap after a warm reply.
A checklist before you send
- 1Is there one sentence that could only have been written to this person?
- 2Is the problem described in their vocabulary rather than my pitch language?
- 3Is there one piece of evidence that this company is real?
- 4Is the ask twenty-five minutes or less, with a specific purpose?
- 5Is there a graceful way for them to say no?
- 6Is it under 130 words?
- 7Have I removed every mention of equity, NDAs and the word MVP?
If you are still building the list these messages will go to, start with How to find a co-founder or How to find startup advisors. The search mechanics are in Boolean search for founders.
Frequently asked questions
How do I message a potential co-founder?
Write 90 to 130 words containing five things: one sentence proving you chose them specifically, two sentences describing the problem in their vocabulary, one piece of evidence that the company is real, an ask for twenty-five minutes, and a graceful way to decline. Do not mention equity, a co-founder role, or an NDA in the first message.
Should I mention equity in the first message?
No. Equity answers a question the reader has not asked yet, and naming a number early converts a conversation between peers into a job offer they can immediately price and decline. Discuss the split once both sides have decided they want to work together, which is usually after a trial project rather than after a first call.
How many times should I follow up?
Three touches in one cycle: the first message, one follow-up around day seven containing genuinely new information, and a short closing note around day twenty-one. Then stop. A re-approach after three months is reasonable if something material has changed, but two full cycles with no reply means stop permanently.
What reply rate should I expect from cold outreach to co-founders?
Roughly 35-45% for ten to twenty individually written messages with specific evidence and a small ask, falling to 2-5% for fully templated outreach at volume. Warm introductions with a forwardable paragraph convert best of all. For founder-level search, quality of targeting matters far more than volume.
How do I ask someone to be an advisor?
Do not ask in the first message. Ask one specific question they are uniquely placed to answer in twenty-five minutes, then report back on what you did with the advice, then come back three weeks later with a second question. Propose the formal arrangement only after two useful conversations, stating the hours commitment before the equity.
Is email or LinkedIn better for founder outreach?
Email, when you can find the address, because it competes with less recruiter volume. A connection request with a short note is a reasonable second choice, and its length limit enforces the discipline of one specific opening line. Avoid contacting the same person on several channels at once.
