Thanks for your detailed feedback. again, as I said up top, "investor" might not be the right term, I think they want to be "business partners" and create a new-co...I'm not sure, and sorry for the confusion

My concerns are mainly on Section 2 and 9. 2- Since the NDA never defines who is the disclosing or receiving party, nor what information has been given by one to the other, can they eventually pursue legal action and only then trying to demonstrate that it was them who provided the information (very difficult for them anyways)

9- This is basically saying that they or us can do whatever we want with that information, right? If this is the case, what would be the point of the NDA anyways?
