I have a new website product which I'm beginning to demo. I have the opportunity to demo to a relatively large potential client. I've found out (from the individual) that they already have a similar product that they previously tried to monetize but would like to look at mine and are interested in switching over to my platform instead given its price point.
There's a natural reluctance since this potential client already has invested time and money into their own platform and has shown that they have tried to monetize it. Most of what I would demo could be completely viable for their own platform.
My first inclination is to ask for an NDA prior to the demo, however, as I've read and would have suspected, that's off putting so early on in the relationship. I've already read that an NDA, from the perspective of a small company like my own, is not very useful against a large company with resources.
So, does this situation warrant an NDA or is there another mechanism to protect my IP and ease my concern that I'm not thinking of?
