Why this matters
Investors see thousands of decks and fund almost none of them cold. A warm introduction transfers borrowed trust: someone the investor already believes says you're worth a meeting. This step is how the list you just built becomes actual meetings.
What "done" looks like
- Every A- and B-tier investor has a mapped intro path or a deliberate cold fallback
- A forwardable three-to-four-sentence blurb with your best traction
- Intros requested through double opt-in, not surprise handoffs
- Meetings booked and tracked against your pipeline
How to do it
- Mine for connectors: founders in the investor's portfolio first, then accelerator networks, angels, and startup lawyers.
- Ask portfolio founders directly — their word carries the most weight, and they'll tell you how the investor actually treats companies.
- Write the forwardable email: what you do, proof it's working, why this investor specifically, one clear ask. The connector should only need to hit forward.
- Use double opt-in: the connector checks with the investor before you're connected.
- Follow up once, politely, then move on — connectors owe you nothing.
- Go cold where no path exists: short, specific, evidence-first. Cold sometimes works; warm just works far more often.
Common mistakes
- Asking a weak tie for an intro to someone they barely know — a lukewarm intro is worse than a sharp cold email
- Sending an essay nobody can forward
- Burning a connector's goodwill on a wrong-stage investor you didn't research
Real-world examples
- YC's published fundraising guides consistently rank intros from portfolio founders as the highest-signal path to an investor.
- Paul Graham's essay "How to Raise Money" treats introductions as the standard entry point to investors.
From a founder's point of view
An intro is someone spending reputation on you. The way to earn it isn't charm; it's being easy to vouch for — a clear blurb, real progress, and follow-through that makes the connector look good for sending you.
Rule of thumb
If your intro request can't be forwarded unedited in ten seconds, rewrite it before you send it.
