I first wrote about VCs and NDAs last November.
Well last week Rick Segal had a whole series of rants on the subject.
First he explains how you should go for confidentiality in the term sheet.
Second he outlines how to handle it in an execution play.
Finally he piles it on by analyzing the last 100 unsolicited business concepts that has been sent to him and were marked as confidential in some manner.
If one of your goals is to raise money in 2007 these are must-reads.
And BTW, the ATDC does not sign NDAs.
