How to Get Warm Intros to VCs (Without a Tier-1 Network)

Who can intro you, how to ask, the double opt-in protocol, and how to build the path before you need it.

Warm introductions are the highest-conversion path to VC meetings. A cold email to a top-tier partner has a response rate below 5%. The same founder, same company, same metrics, introduced by a trusted contact: 60–80%.

The warm intro is not a hack or a trick. It is a signal — it tells the investor that someone whose judgment they trust has already evaluated the founder and believes the meeting is worth their time.

Here's how to build the warm intro infrastructure before you start fundraising.

Who Can Give You a Warm Intro

Not all intros are created equal. Ranked by conversion impact:

1. Portfolio company founders. A founder who has worked with a specific partner at a specific fund, and who endorses you, is the strongest intro that exists. The partner trusts their judgment on founder quality and has a track record with them.

2. Co-investors. If you have existing investors (angels, seed funds), they typically have relationships with Series A funds. An intro from your seed investor to their Series A co-investors is highly credible.

3. Startup lawyers and bankers. Cooley, Wilson Sonsini, and Goldman's startup banking team have relationships with virtually every major fund. They introduce dozens of companies per year. Getting on their radar is worth the effort.

4. Accelerator alumni and partners. YC partners and batch alumni have warm paths to most top-tier funds. Same for a16z Speedrun, South Park Commons, and Pear.

5. Second-degree LinkedIn connections. Weaker than the above but better than cold. A mutual connection who vaguely knows the VC can still make an intro — just know the conversion rate is lower.

6. Other founders, even non-portfolio. If a respected founder in your ecosystem knows the partner and believes in you, their intro can work. It depends on the strength of the introducer's relationship with the VC.

How to Build the Intro Map

Before you start fundraising, build a map of every warm path you have:

  1. List your target funds (using the process from Article 17)
  2. For each fund, list portfolio companies — these are public on every fund's website
  3. For each portfolio company, check LinkedIn — do you have a 1st or 2nd degree connection?
  4. Map your existing investors, lawyers, and advisors — who do they have relationships with?
  5. Use NFX Signal (free) — shows the warm paths from your email network to VCs you want to reach

Document this as a spreadsheet: Fund \| Target Partner \| Warm Path \| Status.

How to Ask for an Intro

Asking for an intro badly is worse than cold outreach. Do it well:

Step 1: Prime the path. Before asking for the intro, build the relationship with the introducer. Don't cold-ask someone for a VC intro. If you don't have a real relationship, start there.

Step 2: Make it easy to say yes. Write the intro email for them. Seriously — draft the exact email you want them to send and give it to them. They can edit it. Most people will use what you've written because it saves them time.

Step 3: Give them an out. Ask if they're comfortable making the intro, not just if they know the person. "I know you know [Partner X] — would you feel comfortable making an intro, or is there a reason you'd prefer not to?" This gives them a face-saving way to decline if there's a reason they shouldn't.

Step 4: Follow up quickly. Once an intro is made, respond within 24 hours. Slow follow-up on a warm intro is one of the most common ways to waste goodwill.

The Double Opt-In Intro

The most effective intro format — preferred by VCs and polite for founders:

  1. Introducer contacts the VC first: "There's a founder I'd like to introduce you to — [Company]. Would you be open to a meeting?"
  2. VC confirms interest
  3. Introducer makes the full intro

This prevents the VC from receiving an intro they didn't want, which can reflect poorly on the introducer. Some of the most connected operators in Silicon Valley specifically use this method and expect you to know it.

Building Relationships Before You Need Them

The best time to build warm intro infrastructure is 6–12 months before your raise. Actions that build the relationship:

  • Attending events where VCs speak (SaaStr, YC Demo Days, AngelConf)
  • Engaging authentically with VC content (Twitter/X, newsletters, blog posts)
  • Sharing your progress publicly — build-in-public updates that VCs can follow
  • Offering to be a reference for a company a VC is diligencing (when you have relevant expertise)

Frequently Asked Questions

Is a weak warm intro better than a cold email?

Mostly yes, with one exception: if the introducer has a negative reputation with the VC, their intro can hurt you. Know the relationship before you use it.

Should I ask multiple people to intro me to the same VC?

No. Pick the best path. Multiple simultaneous intros to the same partner from different people is awkward and can signal a lack of network judgment.

What do I do if I genuinely have no warm path?

Cold outreach (see Article 16) is the option. Alternatively, get into an accelerator (YC, Techstars) whose alumni network creates the warm path automatically. Or use PitchProtocol's structured application to reach thesis-matched funds without needing an intro.
