Warm Introduction

Definition

A warm introduction is a referral to an investor from someone they trust, typically a portfolio founder or co-investor, usually via a forwardable email.

How it comes up in fundraising

Warm intros roughly double or triple reply rates versus cold outreach, but in 2026 they are an accelerant, not a gate: well-targeted cold email gets meetings too.

Frequently asked questions

How do I get warm intros without a network?

Build the target list first, then work backward through portfolio founders and mutual connections; a concise forwardable email makes saying yes easy.

Are cold emails to investors acceptable?

Completely; short, specific, traction-led cold emails to well-matched investors earn 10 to 15 percent reply rates.
