How to meet investors in person in San Francisco without a warm intro

Every fundraising guide says the same thing. Y Combinator's seed guide puts it plainly: outside a demo day, "by far the best way to meet a venture capitalist or an angel is via a warm introduction." Paul Graham's "How to Raise Money" is even shorter: "Before you can talk to investors, you have to be introduced to them."

That's useful advice if you already know people who know investors. If you've just started, or just moved to San Francisco, it can feel like a locked door. A 2025 Hacker News thread asked exactly this: how do founders find investors without warm intros? The answers weren't magic tricks. They were local meetups, your second- and third-degree network, investor scouts, and traction.

Here's how that plays out in practice.

Why the warm intro matters

A warm intro is a filter. Someone the investor trusts is saying "this person is worth twenty minutes." That's why intros vary so much in value. Graham ranks them: the best comes from a well-known investor who has just invested in you, and the next best is "from a founder of a company they've funded."

In his essay on angel investing, he describes the other side of the table: "The Valley basically runs on referrals." Investors find most of their deals through people they know.

So the goal isn't to skip the intro. It's to become someone people are glad to introduce. Meeting people in person is one of the fastest ways to get there, because someone who has seen your product working on your laptop can vouch for you in a way a stranger reading an email can't.

Step 1: Get your proof ready before you go anywhere

You'll meet investors in short, unplanned moments: in a line for coffee, after a demo night, at the next table. Have three things ready:

• One sentence on what it does and who it's for. No buzzwords.
• One number that's moving. Weekly users, revenue, waitlist signups, pilots. Small is fine if it's real and growing.
• A demo you can show on your phone in under a minute.

A commenter in that HN thread put it simply: traction opens doors. You don't need much of it, but you need something to point at.

Step 2: Meet founders before you meet investors

Founders who've raised are the second-best intro source, and they're far easier to meet. One reply in the thread made the point well: the best people to introduce you to investors are other founders, and the founder community generally works on giving. Help someone with a hiring problem, test their product, send them a customer, and an intro tends to follow without you asking.

In San Francisco this is very doable. Builders co-work in cafés and coworking spaces, run build nights and demo nights, and turn up at the same events week after week. Show up regularly and be useful.

Step 3: Go where investors show up without a gatekeeper

Plenty of investors go to things where you don't need an invitation:

• Demo nights and pitch nights. Investors come to see companies. Even if you're not presenting, the conversations afterwards are open.
• Hackathons with investor judges. Shipping something in a weekend is a better first impression than a pitch.
• Talks and fireside chats. The speaker is busy. The other investors in the audience often aren't.
• Open office hours. Some investors hold them. Look on their websites and social profiles.

Be honest with yourself about the odds. At a busy event an investor may talk to thirty people. Your aim isn't to pitch. It's a two-minute conversation they remember and a reason to follow up.

Step 4: Talk to scouts and associates

Another reply in the thread suggested connecting with scouts and inviting them for a coffee close to their office. Scouts and associates are often earlier in their careers, easier to reach, and part of their job is finding companies.

Go in with clear eyes, though. Graham is blunt that "an associate is not a VC. They have no decision-making power," and that partners tend to discount deals that reach them this way. So treat these coffees as a way to learn how a firm thinks and to widen your circle, not as your fundraising pipeline. If you want a specific firm, an intro to a partner from someone they respect still carries the most weight.

Step 5: Ask for advice, then follow up with progress

The first meeting is rarely the one where money changes hands. Ask a real question: "We're seeing X, would you price it like Y?" Then do something with the answer and tell them what happened.

Send a short monthly update: what you shipped, the number, one problem. Keep it to a few lines. Graham notes that "investors who reject you are some of your warmest leads for future fundraising," because anyone who spent real time deciding probably came close to yes. Watching a founder keep their word for a few months is often the extra evidence they need.

Step 6: Use your second-degree network carefully

Ask everyone you meet for one specific introduction, not "anyone you know." Two rules from Graham's essay:

• When an investor commits, ask them to introduce you to other investors they respect.
• Don't ask investors who said no for introductions. That "will in many cases be an anti-recommendation."

Step 7: Cold email as the last resort, done well

YC's guide says that if you have no other options, send investors "a brief, but compelling summary of your business." Brief is the key word: two or three sentences, your number, a link to the product. Mention where you crossed paths if you did. A cold email after a real conversation isn't cold anymore.

What not to do

• Don't pitch someone who came to an event to relax.
• Don't ask for money in the first conversation.
• Don't send a deck to someone who hasn't asked for one.
• Don't treat every investor the same. Look at what they've actually funded first.

Where The Build Nation fits

The Build Nation is a free, real-time network for builders, investors, mentors and businesses, live in San Francisco. It won't hand you a list of investors to pitch, and we don't want it to. What it does is make the in-person part easier.

Your profile shows what you've actually done: things you've shipped, launches, and a proof-of-work grid, never likes or follower counts (see how ranking works). You can start a quick meetup at a café, say a demo or a co-working session, and investors who are members can request to join like anyone else. And if you're going to a demo night listed on Luma, you can paste its link into The Build Nation and mark yourself going. Members going to the same night can then see each other, along with a short list of who they should meet there.

Whether you use it or not, the approach is the same: build something real, meet the founders around you, and let a few people see your progress up close. The warm intros follow from that.
