How to Ask for a Warm Intro to an Investor (2026)

To ask for a warm introduction to an investor, choose a connector who has a real relationship with that specific investor, ask them to check whether the investor wants the intro before making it, and give them a short forwardable email written to the investor. Make the ask specific, make it easy to say no, and only ask for investors who fit your round.

What Is a Warm Introduction to an Investor?

A warm introduction is a referral from someone the investor already knows and trusts, vouching that your company is worth a meeting. It works because the connector is putting their own reputation behind the request.

Investors use intros as a filter. A partner who receives hundreds of decks a month cannot evaluate each one. A referral from a founder they backed, a co-investor or a lawyer they trust tells them someone with context has already screened you.

Paul Graham makes the point bluntly in How to Raise Money: before you can talk to most investors, you have to be introduced to them, and intros vary greatly in effectiveness. Cold outreach can work — see how to get investor meetings without warm introductions — but a strong intro shortens the path to a first meeting.

Who Should You Ask for an Introduction?

Ask the person with the strongest relationship to the specific investor, ranked by how much the investor trusts their judgment on deals. Graham's ordering is the most cited: the best intro is from a well-known investor who has just invested in you, and the next best is from a founder of a company they have funded.

A practical ranking of connectors, strongest first:

Strength of tie beats fame. A connector who emails the investor monthly will get a reply; a famous name who barely knows the investor will not.

How Do You Choose Which Investors to Ask About?

Only request intros to investors whose thesis, stage and check size match your round; every misfit intro burns a connector's goodwill. Connectors will make two or three intros for you before they start declining. Spend them on investors who could actually lead or join.

Before you write a single ask, check four things for each target:

This is the work the GIGABOOST AI investor targeting engine does at scale: it scores investors across 25 fit factors from a database of 340,000+ verified investors, so you know which names are worth a connector's time. For the manual method, see how to find investors that match your thesis.

What Is a Double Opt-In Introduction?

A double opt-in introduction means the connector asks the investor whether they want the intro before making it, and only connects you if the investor agrees. Fred Wilson of Union Square Ventures laid out the practice in a 2009 post, The Double Opt-In Introduction, as basic email-intro etiquette.

The sequence:

Double opt-in protects the connector. An investor who opted in is primed to take the meeting. A cold group intro the investor did not ask for puts them in the position of ignoring someone in front of a mutual contact, and it costs the connector credibility.

It also gives you signal. A decline at the opt-in stage is a fast, cheap no. Log it, and do not ask a second connector to reach the same investor for the same round.

How Do You Write a Forwardable Intro Email?

A forwardable email is a short message addressed to the investor, not the connector, that the connector can forward without rewriting. Investor Alex Iskold laid out the format in Why and How You Should Write a Forwardable Introduction Email.

Send two emails in one: a brief note to the connector, and the forwardable section below it.

The note to the connector:

Hi Sam — would you be open to introducing me to Priya at [Fund]? They led two seed rounds in vertical payments software this year, and we are raising a $3M seed for exactly that. Only if you think it is a fit — I have written a short note below you can forward to see if she is interested. No worries at all if not.

The forwardable section, written for the investor:

Acme Pay builds payments infrastructure for independent veterinary clinics. We process payments for 140 clinics, growing 18% month over month for the last six months, and replaced two incumbents in our last 20 deals. We are raising a $3M seed to expand to dental practices. Your investments in vertical payments make you the investor we most want to talk to. Deck attached.

The company, numbers and names above are invented placeholders to show the format, not a real raise. Rules for the forwardable section:

Before the deck goes out, run it through GIGABOOST AI deck review so the first thing a referred investor opens is your strongest version.

Why Do Warm Intros Matter Under Rule 506(b)?

In a Rule 506(b) offering, you cannot use general solicitation, and contacting investors through people with real, pre-existing relationships is one recognized way to show you did not. Most seed rounds are raised under 506(b), so the way you reach investors is a legal question as well as a sales one.

Rule 506(b) lets a company raise unlimited capital from accredited investors, subject to the general solicitation ban in Rule 502(c). The SEC's Rule 506(b) overview summarizes the conditions.

The SEC staff's Securities Act Rules Compliance and Disclosure Interpretations address this directly in Questions 256.29 through 256.32:

Question 256.30 adds that there is no minimum waiting period, as long as the relationship exists before the offering, and the staff's Citizen VC no-action letter calls the quality of the relationship the most important factor. Demo days have their own path: Rule 148 exempts qualifying multi-issuer events from the general solicitation ban.

If you want to advertise publicly instead, Rule 506(c) allows it, with mandatory accredited-investor verification. See 506(c) vs 506(b). Your securities counsel should confirm which exemption fits how you plan to reach investors.

Can You Pay Someone for Investor Introductions?

Paying a connector a percentage of the money raised is risky, because transaction-based compensation is a hallmark of acting as an unregistered broker. A flat advisory fee or equity grant for real work is a different conversation, but still one for counsel.

The SEC proposed a conditional exemption for "finders" in 2020, in Release No. 34-90112, which would have defined limited activities finders could perform without registering. It was a proposal, and founders should not treat it as a safe harbor. Using an unregistered intermediary can create rescission risk for the round.

Thank connectors instead with what they actually value: a short update when the intro converts, a return favor, and a monthly investor update.

How Do You Follow Up After the Intro?

Reply to the introduction email within 24 hours, move the connector to BCC, offer two or three specific times, and report the outcome back to the connector either way. Speed signals you take the investor's time seriously.

Frequently Asked Questions

How do you ask someone for an introduction to an investor?

Pick someone with a real relationship to that specific investor, and ask them in a short email whether they would be open to checking if the investor wants an intro. Include a forwardable paragraph addressed to the investor, explain why that investor fits your round, and make it easy for the connector to decline.

What is a double opt-in introduction?

A double opt-in introduction is one where the connector asks the investor whether they want to be introduced before connecting both parties. The intro only happens if the investor agrees. Fred Wilson of Union Square Ventures described the practice in a 2009 post on email-intro etiquette.

What should a forwardable intro email include?

A forwardable intro email should include what the company does, its strongest traction number, the round size, one specific reason the investor fits, and a link to the deck. Keep it to five sentences or fewer and write it so it reads naturally when forwarded without edits.

Who gives the best warm introductions to investors?

The strongest introduction comes from an investor who has just committed to your round, followed by a founder that investor has previously funded, according to Paul Graham's How to Raise Money. Co-investors, lawyers and accelerator partners with real deal history are next. Mutual connections with no relationship to the investor carry little weight.

Do you need a warm introduction to raise venture capital?

No, but it helps. Many investors prioritize referred deals, and in a Rule 506(b) round, introductions through people with pre-existing, substantive relationships help show the company did not use general solicitation. Well-targeted cold outreach to investors who fit your stage and sector also produces meetings.

Can you pay someone to introduce you to investors?

Paying a percentage of capital raised to someone who is not a registered broker-dealer creates securities-law risk for both parties and can jeopardize the offering. The SEC proposed a limited finder exemption in 2020, but it was a proposal, not a safe harbor. Talk to securities counsel before agreeing to any success fee.
