Warm Intro

A warm intro is an introduction to an investor (or customer, partner, hire) made by a mutual trusted contact who can vouch for the founder. It dramatically outperforms cold outreach in conversion rates (often producing 5-10x higher response rates and meeting conversion), with warm intros being the dominant path to investor meetings in the venture industry and the introduction format most investors strongly prefer. Cold outreach works occasionally; warm intros work systematically. A good warm intro is typically what unlocks the formal Partner Introduction inside a venture firm.

The warm-intro structure:

Double opt-in (standard practice):

• Person making intro asks both parties first.
• "Can I introduce you to X?" to recipient.
• "Can I introduce you to Y?" to founder.
• Only after both say yes, intro is made.

Single-line intro email:

• Brief context on each party.
• Suggests next step (meeting).
• Drops out of conversation after intro.

Forward-able forward email (founder writes):

• Sent to intro-maker before they make the intro.
• Includes 1-paragraph company summary.
• Easy for intro-maker to copy-paste.

What makes a warm intro work:

Mutual trust between intro-maker and recipient: matters enormously. Recipient trusts the intro-maker's judgment.

Strong founder/company signal in the intro: brief but compelling.

Specific ask: what's the founder hoping to discuss? Meeting? Advice? Money?

No pressure on recipient: respects their time.

Sources of warm intros:

• Existing investors (their network is the most valuable).
• Other founders in your network.
• Advisors.
• Former colleagues.
• Service providers (lawyers, accountants).
• Industry connections.

Warm intro success rates (rough patterns):

• Cold outreach: 1-5% response, <1% meeting.
• Warm intro: 50-80% response, 25-50% meeting.
• The difference is enormous.

What founders get wrong: Relying on cold outreach because they don't have warm intro paths, when investing in network development would dramatically improve fundraising outcomes. The right discipline: build network deliberately, make warm intros for others (reciprocity), use double opt-in.
