For "other" startups whose product/funding appear to be uncertain and demand that I sign an NDA, I started requesting a lawyer lookover fee for the issuing party. Note, I'm upfront and actually tell them this is what my attorney charges to lookover an NDA.
Note - I am bootstrapping my own startup while offering expertise to contract technical software development services for other startups and companies.
I've had some nasty responses from such parties. I'm not actively looking for work, and they are the one requesting my time. Sadly, sometimes these people were once "San Francisco friends."
How would you deal with such situations - politically sensitively?
Note: these people are not necessarily "clients", but potential prospective clients. Some of them strong sell me to the point where it feels like they are trying to extort me to work for them.
