Warm Introduction
A Warm Introduction is an introduction made by an existing acquaintance to someone with whom you would like to become aquatinted, that is coupled with some sort of personal endorsement. In the venture capital world, a warm introduction is the gold standard.
Example:
Startup Founder: Hey Jerry, I just want you to know that I really value our friendship, and if you ever need anything, anything at all, I’m your guy. Because that’s what friends do for each other.
Jerry: Thanks… What do you want?
Founder: Nothing much. Just a warm introduction to 10 of your closest Accredited Investor friends.
