What Is Warm Intro?
Updated
Definition
A warm intro is an introduction to an investor, customer, or hire made by someone who already trusts both parties — carrying social proof that cold outreach lacks.
Useful for: Founders, Investors
A warm intro is a referral from a trusted mutual connection — the default path into venture partner meetings and many enterprise sales cycles.
How it works
Effective warm intros follow a pattern:
- Connector knows the investor and founder
- Double opt-in: connector asks investor if they want the intro; founder sends forwardable blurb
- Short email with context, traction bullets, and ask (20-minute call)
Sources include portfolio founders, angels, executives, lawyers, and other investors. Quality beats quantity — intros from people the investor has made money with rank highest.
Founders should make intros easy: two sentences on problem, metrics, round status, and deck link. Chasing intros without fit burns connectors’ social capital.
Some firms publish intake forms or associate inboxes for cold inbound — still lower conversion than founder-to-founder intros.
Why it matters
- Founders: Warm intros shorten time to first partner meeting and improve term sheet odds versus cold spray. Map target firms to who can intro you honestly.
- Investors: Introducers signal deal quality and reduce diligence waste. Repeated bad intros from the same connector lose credibility.
Common mistake
Mass-bcc intro requests without researching stage and sector fit. Connectors refuse; investors remember the noise.
