There are three buckets you should target to provide intros to investors:
Investors who have confidence in you and your abilities (you probably don´t know many)
Founders, in your network, who have received an investment (these make for strong warm introductions).
Trusted network contacts with working or perosnal relationships with investors (consider ex-colleagues, fellow university or MBA students. Your primary objective with this process is to find the best person to give you an intro; someone who is seen as credible to the investor.
This is because of social proof: you want to get an intro from someone the investor respects and/or has put her money where her mouth is. Make the time and effort to find a warm intro.
