I'm a tech entrepreneur who recently met with another tech entrepreneur who is in the same industry. He wants to potentially work with me but before he can talk about his venture he wants me to sign a non-disclosure agreement.
Most established entrepreneurs aren't fond of signing NDA's because they can be too open worded and may prevent the entrepreneur from developing ideas and businesses off the fringe of the idea/trade secrets covered within the NDA. I certainly wouldn't sign an NDA unless there was an extremely compelling reason to. I would also be inclined to make sure the NDA was applied equally to both parties involved, and was very specific as to scope.
