How to Get a Warm Introduction to a VC (and When Cold Works)

To get a warm introduction to a VC, pick someone the investor already trusts (ideally a founder they backed or a co-investor), ask that person to check with the investor first, and hand them a short forwardable email they can send without editing. If no credible path exists, a targeted cold email to a firm that reads inbound is often the faster route.

Definition: A warm introduction is a referral from someone the investor knows and trusts, usually by email, that puts your company in front of them with a borrowed signal of credibility. A double opt-in introduction is one where the connector asks both sides for permission before connecting them.

An intro isn't a door. It's a recommendation, and the investor weighs it by who signed it.

This guide covers the mechanics of the intro itself. If you're still building the relationships that make intros possible, start with our 90-day plan to network with VCs. If you've decided to go cold, our guide to writing a cold email to an investor has the templates.

Why a warm introduction to a VC carries weight

Investors are buried in companies, and a trusted referral is one of the cheapest filters they have.

The data backs that up. In a survey of 885 venture capitalists at 681 firms by Paul Gompers, Will Gornall, Steven Kaplan and Ilya Strebulaev (NBER working paper 22587), over 30 percent of deals came through the investors' professional networks, 20 percent were referred by other investors and 8 percent by existing portfolio companies. Only 10 percent came inbound from company management.

NFX lays out the funnel from the investor's side. In its 2019 piece on how VCs decide to take a first meeting (updated in 2023), the firm sketches a typical VC who is introduced to about 1,000 companies a year, meets about 200 and invests in about 4. On those numbers, about 80 percent of introduced companies never get a first meeting. A warm intro gets you read. It doesn't get you funded.

Our read: the intro is less a key than a pre-filter. The investor outsources the first screen to someone whose judgment they trust, which is why the introducer matters so much.

Who makes the best warm introduction to a VC?

Not every intro is equal. NFX's framing is that your odds of a meeting rise with the perceived quality of your referrer, and that founders and industry experts tend to top an investor's trust list. We'd rank the usual suspects roughly like this:

An investor who just backed you. Paul Graham's 2013 essay "How to Raise Money" puts a well-known investor who has just invested at the top. They're putting money behind the recommendation, which is hard to fake.
A founder the investor has funded. Portfolio founders have a working relationship with the partner and little reason to waste their time. Graham ranks them second; NFX puts founders first.
A co-investor or angel who regularly invests alongside the fund. They know the fund's taste and speak its language.
Startup lawyers and recruiters. Mark Suster (now at Upfront Ventures) named corporate lawyers among the strongest early-stage referral sources in a 2009 post, because they sit close to deals.
Operators and industry experts the investor respects. Especially useful in specialized sectors, where they can vouch for the market as well as the founder.
Friends of friends. A thin connection is still a connection, but a forwarded note from someone the partner met once is closer to cold than warm.

Two things move a weak intro up the list: specific knowledge of you ("I've watched this team ship for a year") and a stake in the outcome (they invested, or they're a customer).

Investors don't fully agree on the top of that list. Graham puts a new backer first; NFX notes that intros from your current investors are sometimes discounted, because struggling companies are often the ones shopped to many firms, and ranks founders and experts higher for having no conflicting incentive. Our read: a backer's intro carries weight when it comes with conviction and a fresh check, and less when it looks like a favor to a struggling portfolio company.

How double opt-in intros work

Fred Wilson of Union Square Ventures helped popularize the practice in venture with a 2009 AVC post proposing that connectors ask both parties for permission before making an email introduction. It's now common etiquette in venture.

The flow usually runs like this:

You ask the connector, naming one specific partner and why that partner fits.
You send the connector a forwardable email (template below).
The connector forwards it to the investor with a line of their own and asks whether they'd like an intro.
The investor opts in or declines. Either way, the connector tells you.
If yes, the connector makes the intro by email, copying you both.
You reply within a day, move the connector to BCC, and propose times.

Double opt-in protects the connector's relationship, spares the investor awkward declines, and gives you a cleaner yes.

The forwardable email: a template you can copy

The forwardable email is the single most useful thing you can give a connector. It lets them help you in 30 seconds without writing anything.

Keep it short enough to read on a phone, written in the third person or addressed so it can be forwarded cleanly, and readable without any attachments or earlier context. An illustrative version:

Subject: Intro request: Ledgerline (AP automation for clinics), raising $2M seed

Hi [Connector],

Thanks again for offering to check with [Partner name] at [Fund]. Here's a short note you can forward as is.

Ledgerline automates accounts payable for multi-location medical clinics, which still process supplier invoices by hand. We're at $41K in monthly recurring revenue, up from $12K nine months ago, with 37 clinic groups paying and no paid marketing.

[Partner name] backed [Portfolio company] and wrote about back-office software for healthcare providers, so we think the fit is close.

We're raising a $2M seed and would value a 25-minute call in the next two weeks. Deck: [browser link]

[Your name], CEO, Ledgerline

The company and numbers are fictional. The shape is the point: what you do, one proof point, why this partner, the raise and a small ask.

What to send the connector alongside it

One sentence on why you picked this partner, so the connector can say it in their own words.
Permission to say no. Something like "If it isn't the right fit or the right moment, no problem at all."
A short deck link that opens in a browser. The pitch deck structure guide covers what belongs in it.

How to ask for a warm introduction without burning the relationship

An intro is a favor spent from someone else's account. A few habits make it easier to grant:

Ask for one or two named partners, not "anyone at the fund." A specific ask shows homework and makes the connector's job easy.
Don't send a deck and "let me know who might be interested." That asks the connector to do your research and stake their name on it.
Don't run parallel intros to the same partner. Two connectors pitching you to one person reads as disorganized.
Close the loop. Tell the connector how the meeting went, even if it was a pass. The next ask gets easier.

For founders with a thin network: your existing angels, your lawyer and founders you've helped are often closer to investors than you think. Our sibling guide on raising with no investor network covers building those paths from zero.

Map your paths before you ask

Before you send a single request, build a map. Start from the funds that actually fit your stage, sector and check size. Our sibling guide on how to find investors shows how to build and rank that list. Then, for each target partner, note:

portfolio founders you know or could reach;
angels and funds that co-invested with them recently;
lawyers, recruiters and operators in their orbit;
the strongest single path, and a backup.

This is tedious by hand. If you'd rather start from a ranked list, the investor matching in 1752 Fundraising scores angels, VC firms and family offices (depending on plan) against your deck, stage, sector and check size, with a confidence score on each match, so you can spend your time on the introducer map instead of the research.

Then track every request (connector, partner, date asked, status) in the same place you track meetings. Our guide to building an investor pipeline has the stages.

A worked example: warm and cold side by side

Here's an illustrative plan for a seed founder targeting 30 partners. The conversion rates are assumptions for the sake of the arithmetic, not benchmarks; your numbers will differ.

Mapping: 21 of the 30 partners (70 percent) have a credible path through a founder, angel or lawyer the founder knows.
Connector yes: 18 of those 21 connectors (about 86 percent) agree to ask.
Investor opt-in: if about 35 percent of those 18 investors say yes, that's roughly 6 first meetings (18 times 0.35 is 6.3).
Cold track: for the 9 partners with no path, plus 31 more good-fit firms, the founder sends 40 targeted cold emails. At an assumed 8 percent meeting rate, that's about 3 more meetings (40 times 0.08 is 3.2).

About nine first meetings from two tracks. For scale, DocSend's 2023 seed report found founders contacted 66 investors on average and set 38 meetings. The lesson we'd take: warm paths tend to convert better per ask, but they run out. Most founders need both tracks running at once.

When cold works better than warm

Warm intros are a strong default. They're not the only door.

Cold tends to work when:

The firm says it reads inbound. Y Combinator's own FAQ states that it doesn't rely on introductions the way many investors do and considers all applications equally. Many accelerators and some pre-seed funds run open application forms for the same reason.
The investor is newer or outside the usual hubs. Elizabeth Yin, who went on to co-found Hustle Fund, argued in 2016 (in a post updated in 2026) that cold email is increasingly viable because investors now look for deals outside the usual Silicon Valley networks and many newer funds are hungry for them.
Your only path is a weak one. A lukewarm intro from someone the partner barely knows can do more harm than a sharp cold note that leads with traction.
Your numbers do the talking. Strong revenue growth in the first two lines can stand in for a referrer.

A useful hybrid is the referenced cold email: you don't have a formal intro, but a mutual contact has said you can mention their name. That's covered in the cold email guide linked above.

What investors say, and where they disagree

Investors don't agree on how much intros should matter, and the split is worth knowing.

The intro-first camp. YC's 2016 seed guide by Geoff Ralston calls a warm intro "by far the best way" to meet an investor and treats a brief cold summary as the fallback. Suster's 2009 post went further, calling unsolicited submissions the worst way to approach a VC.

The open-door camp. Yin's cold email tips assume investors will read a short note with strong metrics. YC says it considers all applications equally rather than relying on intros.

The critics. Investor Del Johnson's 2019 essay "Ban Warm Introductions!" argued that intro requirements filter for proximity to venture networks rather than founder quality, and so cost funds both diversity and returns.

Our view sits between them. Intros still shape who gets a fast read at many firms, so we'd use every genuine one you have. We'd also take the firms that say they read cold at their word.

"But warm intros are just gatekeeping"

There's a real case here. Intro requirements reward founders who went to the right school, worked at the right company or live in the right city. Everyone else spends weeks chasing referrals that well-connected founders get in a text.

But.

An unfair system is still the one you're raising in. The practical answer, in our view, is to build paths deliberately (founders, angels, communities, programs) and to go cold to firms that have shown they'll read it. Complaining about the door doesn't open it. A good map often does.

Common mistakes with investor introductions

Asking strangers on LinkedIn for intros. If they can't vouch for you, the intro is cold with an extra step.
Making the connector write the pitch. Send the forwardable email with each request.
Slow replies after the intro lands. A same-day or next-day reply keeps momentum; a week of silence wastes the favor.
Forgetting to thank the connector. A short update after the meeting is often what earns the next intro.

Where we land

Use warm paths wherever you genuinely have them, and pick the introducer by trust, not seniority. Make the ask small and specific, and do the connector's work for them.

Run a cold track in parallel to the firms that say they read inbound. That's our approach; plenty of founders raise another way.

If your company is early and you want a structured way to widen your network, 1752vc's Accelerate program is a remote program for early-stage startups ready to grow, with founder-led sales training and access to a network of 850+ investors.

The bottom line

A warm introduction to a VC is borrowed trust. Choose who you borrow it from carefully, and give them an email they can forward in one click.

The intro gets you read.

The company still has to get you funded.

Key takeaways

In a survey of almost 900 VCs, over 30 percent of deals came through investors' networks and only 10 percent came inbound from management.
The strongest introducers tend to be investors who just backed you and founders the investor has funded.
Double opt-in intros, where the connector asks the investor first, protect everyone's time and relationships.
A short forwardable email with one proof point and one ask makes it easy for a connector to help.
Cold outreach can work well with firms that say they read inbound, such as YC, which states it does not rely on introductions.

Frequently asked questions

What is a double opt-in introduction?

A double opt-in introduction is one where the connector asks the investor for permission before connecting you, rather than copying you both on an unexpected email. Fred Wilson of Union Square Ventures helped popularize the practice in a 2009 post. It protects the connector's relationship and lets the investor decline quietly, so the intros that do happen tend to be to people who want to meet.

What is a forwardable email for investors?

A forwardable email is a short, self-contained note you write for a connector to forward to an investor without editing. It usually covers what the company does, one strong proof point, why that specific partner fits, the round size and a small ask, plus a deck link that opens in a browser. It saves the connector time and controls how you are described.

Who should I ask for an introduction to a VC?

Start with people the investor already trusts: investors who have just backed you, founders in that VC's portfolio, angels who co-invest with the fund, and startup lawyers who work with them. The connector should be able to say something specific about you. A thin connection who barely knows you or the partner often adds little over a well-written cold email.

Is a warm intro better than a cold email to a VC?

In most cases a warm intro gets a faster read, since a large share of venture deals come through investor networks and referrals. Cold email still works, especially with accelerators, newer pre-seed funds and firms that say they read inbound. Many founders run both tracks at once: warm paths where they exist, targeted cold notes everywhere else.

How do you reply to an investor introduction email?

Reply within a day, thank the connector and move them to BCC so their inbox stays clear. Then address the investor directly with one line on why you are excited to talk, a few specific time options or a scheduling link, and the deck link if they have not seen it. Afterward, tell the connector how the conversation went.
