To ask for an introduction, name one specific person and one specific reason, send your mutual contact a short request with an explicit way to say no, and attach a forwardable note written for the other person so your contact only has to add a line and press forward. Your contact then asks the other person privately, and makes the introduction only after a yes. That is the double opt-in standard. After the introduction, reply within a day, move your contact to BCC, and tell them how it went.

That paragraph is the whole method. The rest of this guide is about why each piece exists, because the founders who fumble intros rarely skip a step out of laziness. They skip it because they do not see what the step protects. A warm introduction is the most reliable way a small company gets a conversation it has not earned yet, and it is also the easiest ask in founder life to get quietly wrong, in a way nobody tells you about.

Below: the double opt-in standard, a fill-in template for the ask and the forwardable blurb, a checklist for both sides of the introduction, and the part almost every guide leaves out, which is how to keep intros coming after the first one.

Why do warm intros convert, and why do people stall?

They convert because of borrowed trust. A stranger who receives your cold email has to decide, from a subject line, whether you are worth thirty seconds. The same stranger receiving a note from someone they already trust has had that decision made for them. The connector is effectively vouching that you are real, that you will not waste their time, and that the conversation is worth having.

There is solid research behind the idea that the people you know less well are the ones who open new doors. Mark Granovetter's 1973 paper The Strength of Weak Ties argued that acquaintances connect you to information your close circle does not have. A randomized experiment published in Science in 2022 tested that at scale across roughly 20 million LinkedIn users, and as MIT News reported on the weak ties study, moderately weak ties were the most useful for landing new jobs, more than either the strongest or the very weakest connections. That study measured job mobility, not sales or partnerships, so treat it as a direction rather than a promise. The practical lesson still holds: your best connector for a given intro is often not your closest friend.

People stall on making intros for the reason founders forget. When you ask for an introduction, you are asking the connector to spend their own reputation on you. If the conversation goes badly, the recipient remembers who sent it. A connector who hesitates is not being unhelpful. They are doing arithmetic about a limited resource, and a good ask is one that makes the arithmetic easy.

An intro request is a withdrawal from someone else's account. Write it like you know that.

The comparison below shows why the method matters as much as the connection. The same person, reached three different ways, gets three very different messages.

FactorCold emailLazy intro (“you two should talk”)Double opt-in with a blurb
Who carries the riskOnly youThe connector, without being askedThe connector, knowingly and briefly
What the recipient knows before replyingWhatever your first line managesA name and “you two should talk”Who you are, why them, and the exact ask
Easy way to declineIgnore itNone, ignoring it snubs a friendSay no privately, nobody is embarrassed
Chance the connector does it againNot applicableLow, they spent trust and got nothing backHigh, if you close the loop

Notice that the lazy intro is not a middle ground between cold and warm. It is often the worst of the three, because it forces a stranger to either take a call they did not ask for or ignore a friend. A well-written cold email beats a careless introduction, and a careful introduction beats both.

What is a double opt-in introduction?

A double opt-in introduction is one where the connector gets agreement from both people before connecting them. You opted in by asking. The connector then forwards a short note to the other person privately, and only sends the actual introduction if that person says yes. The practice was popularized by investor Fred Wilson in 2009, and it has become the default among people who receive a lot of introductions, for good reason.

It protects the recipient

Nobody wakes up to an email that obliges them to take a call. An introduction that arrives without warning is an ambush, however friendly the wording.

It protects the connector

A private no costs the connector nothing. A public no, sent to both people in one thread, costs them a little with each of you.

It protects you

When the intro lands, the other person already said they want the conversation. You start at interest rather than at obligation.

As the asker, you do not control whether your connector follows the double opt-in standard. You do control how easy it is. A request that includes a ready-to-forward note turns the private check into a thirty-second job, which is why the next section is the most important part of this guide.

The forwardable blurb template

Send two things in one email: a short ask addressed to your connector, and below it a separate note addressed to the person you want to meet. The connector reads the first, then forwards the second. Write the email your connector wishes you had sent, which is one they can act on without composing a single sentence of their own except the one only they can write.

01

The ask, to your connector

Subject: Quick question about ______

Hi ______,

Hope ______ is going well. [One true line about something they did recently.]

Would you be open to introducing me to ______ at ______? I am building ______, and I would like to ask them about ______ because ______.

Completely fine to say no, especially if you do not know them well or the timing is wrong. I will not ask twice.

If you are up for it, I wrote a short note below you can forward as is, or cut however you like.

Thanks either way,

______

02

The forwardable blurb, for the other person

Hi ______,

[Connector: one line on how you know me.]

______ is the founder of ______, which helps ______ do ______ without ______.

They wanted to reach you specifically because ______.

What they are hoping for: ______. That is the whole ask.

Why it might be worth your time: ______.

Happy to connect you two if you are open to it. If not, no reply needed.

  • How you know me: Left blank for the connector on purpose. It is the only sentence that transfers their trust, so it has to be in their words.
  • Founder of ______, which helps ______: One sentence a stranger can repeat. If you need two sentences to say what you do, fix that before asking anyone for anything.
  • Reach you specifically because: Something they wrote, built, or said in public. This is what separates an introduction from a mass forward.
  • What they are hoping for: A small, finite ask: one question, fifteen minutes, a view on one decision. Never “pick your brain”.
  • If not, no reply needed: The out lets the recipient decline in silence, which is exactly what makes a yes feel safe to give.

Read the blurb as if you were the recipient and had never heard of you. If any line would make you wonder what this person actually wants, it is not finished. The test that catches most drafts: could the recipient answer the ask in one reply without needing a call to understand it? If not, the ask is too big or too vague.

Length matters more here than anywhere else in founder writing. The blurb is going to be read on a phone, forwarded by someone doing you a favor between other tasks. Five sentences is plenty. If you find yourself adding a sixth to explain your product, the product explanation is the problem, and the fix belongs on your landing page before it belongs in anybody's inbox.

How do you ask without it being awkward?

Awkwardness comes from ambiguity, not from asking. An ask feels uncomfortable to receive when the connector cannot tell what you want, how much work it is, or what happens if they say no. Answer all three in the request and most of the discomfort disappears on both sides.

  1. Specific person. “Anyone you know at a fintech” is a research project you are handing to someone else. “Priya, who runs partnerships at Acme” is an ask.
  2. Specific reason. Say why this person and not the ten others with the same job title. Something they wrote or built in public is the strongest reason, because it proves you did the reading.
  3. Small ask. One question answered by email, or fifteen minutes. A request for “advice” or a “quick chat” with no topic is the one most people quietly decline.
  4. Easy out. Say in plain words that no is fine and that you will not ask again. Then do not ask again.
  5. One at a time. Three intro requests in one email turns a favor into a to-do list. Ask for the one that matters most and let a good outcome earn the next.

One more judgment call: before you ask, check that the connection is real. A shared connection on LinkedIn frequently means two people accepted an invite years ago and have never spoken. Ask your contact how well they know the person, and treat “not well” as a complete answer. A reluctant introduction does more damage than none.

The connector etiquette checklist, both sides

Every guide to this topic is written for the person asking. That misses half the transaction. You will be the connector soon, and the habits that make you a good one are the same habits that make people want to introduce you. Run your next intro against both columns.

If you are asking

  • Named one person, not “anyone at” a company
  • Confirmed the connector knows them for real
  • Made the ask small and finite
  • Gave the connector an explicit, guilt-free out
  • Wrote the forwardable blurb so they edit, not compose
  • Asked this connector for no more than one intro at a time
  • Replied to the introduction within a day
  • Moved the connector to BCC in that reply
  • Told the connector the outcome within a week
  • Offered something back, and meant it

If you are connecting

  • Asked the other person privately before connecting anyone
  • Forwarded a real blurb, never a bare “you two should meet”
  • Said so honestly when the relationship was too thin
  • Declined when the ask spends more trust than it earns
  • Made the intro in one short email, only after a yes
  • Stepped out of the thread after the first reply
  • Kept a note of who they introduced and why
  • Noticed who closed the loop, and who did not

The connector column has one item people resist: declining. Saying “I do not think I am the right person for this one” protects the relationship you would otherwise be spending, and it is kinder to the asker than a half-hearted forward that goes nowhere. The best connectors say no often, which is exactly why their yes is worth something.

How do you become intro-worthy?

By making introductions yourself, and by keeping track. Intros run on reciprocity, and reciprocity that nobody tracks decays into two failure modes: the founder who asks constantly and gives nothing, and the generous connector who burns out because nobody ever returns the favor. The fix is a simple ledger, even a spreadsheet, with four columns: who introduced you, to whom, what came of it, and what you gave back.

Look at the ratio every quarter. If you have received five introductions and made none, you are drawing down goodwill that will not refill on its own. The fastest way to receive good introductions is to become known as someone who makes them, and that reputation is built one careful double opt-in at a time.

This is the same principle behind every durable founder relationship, from co-marketing partnerships to collaborations with small creators: the arrangement lasts as long as both sides can see it is fair. It is also why introductions belong inside a solo founder GTM strategy rather than beside it. They are a channel, and a channel you can keep open only if you maintain it.

There is a timing argument too. Search is becoming harder to win for everyone, not just for small companies. In GoodFirms' 2026 survey of SEO and marketing professionals, 65% named adapting to AI-driven search as their biggest SEO challenge, and while 43% called AI optimization a core strategy, only 14% track whether AI tools cite them at all. When the discovery channels everyone relies on get less predictable, the channels that run through people get relatively more valuable. Relationships compound in a way rankings do not.

Tracking reciprocity by hand is tedious, which is why most people stop. That is the problem Favors.dev was built around. It is a founder marketing co-op running on a points economy: you earn points by doing verified marketing favors for other founders and spend them to request help back, so the ledger keeps itself. Warm introductions are one of those favors. A founder describes the kind of person they want to meet, and a member who knows someone who fits makes a double opt-in introduction, asking their contact first. The founder approves once the intro actually lands, and the member who made it earns 1,200 points, which they can spend on introductions of their own. You can see the open requests in the favors queue.

What do you do after the intro lands?

Reply within a day, and in that reply thank the connector and move them to BCC. This is the single step that most decides whether you get a second introduction from the same person. A connector who watches you respond quickly and graciously learns that you are safe to introduce. A connector who waits a week to see whether you ever replied learns the opposite.

  1. Same day or next day: reply, thank the connector in one line, move them to BCC, and propose the small thing you asked for with two concrete time options or the question itself.
  2. After the conversation: send the other person a short thank-you with anything you promised during the call. Deliver it, even if it is minor.
  3. Within a week: tell the connector what happened. A good outcome, a polite dead end, or a “they never replied” all count. Silence is the only wrong answer.
  4. Whenever you can: make an introduction for the connector, or for anyone. The ledger does not care whether the favor goes back to the same person.
Closing the loop is not good manners. It is the receipt that makes the next introduction possible.

Introductions also produce assets long after the conversation ends. The people you meet this way become podcast hosts who invite you on, newsletter writers who mention you, and early users who leave a named review. That kind of attributed, third-party material is what answer engines increasingly draw on when they assemble a response, far more than anything you publish about yourself. If the intro leads to a first sale, the first ten paying customers playbook covers what to do next.

Frequently asked questions

How do you politely ask someone for an introduction?

Name one specific person, give one specific reason you want to talk to them, and make the ask small enough to answer in a sentence. Then give your contact an explicit way to say no, such as noting that it is completely fine if they do not know the person well. Attach a short forwardable note written for the other person, so your contact only has to add one line about how they know you and hit forward. Politeness in an intro request is mostly about removing work and removing obligation from the person you are asking.

What is a double opt-in introduction?

A double opt-in introduction is one where the connector gets a yes from both people before connecting them. The person asking has already opted in by making the request. The connector then forwards a short note to the other person privately and only sends the introduction email if that person agrees. It protects the recipient from being ambushed, protects the connector's relationship, and means that when the introduction does arrive, both sides already want the conversation. The term is widely credited to investor Fred Wilson, who described the practice in 2009.

What should a forwardable intro email include?

Four things, in about five sentences: who you are and what you build in one line a stranger could repeat, why you want to reach this person in particular, exactly what you are asking for, and why it might be worth their time. Leave a blank for the connector to write how they know you, since that line carries their trust and has to be in their own words. Close with an easy out so the recipient can decline without replying. Keep it short enough to read on a phone.

How do you ask for an introduction on LinkedIn?

Use LinkedIn to find the mutual connection, then make the actual ask by direct message or email, not through a generic request feature. Before asking, check that the shared connection is a real relationship: a mutual connection on a profile often means two people accepted an invite years ago and have never spoken. Send the same short ask and forwardable blurb you would send by email. If your contact says they barely know the person, thank them and move on rather than pushing, because a reluctant intro is worse than no intro.

What should you do if the person does not respond after the introduction?

Send one polite follow-up about five business days later, on the same thread, with the connector already in BCC. Keep it to two lines and restate the small ask. If there is still no reply, stop. Then tell the connector briefly that you followed up once and are leaving it there, and thank them again. That message matters more than it seems, because it shows the connector their trust was handled carefully, which is what makes them willing to introduce you to someone else later.
