Yeah there is a level of paranoia that can be problematically isolating. In my experience it really depends on the type of idea, the other types of validation you already have, and your existing relationship to the funding network. The more moonshot the idea, the more validation you can get outside of funding pitches, and the less cozy your relationship with the (well-networked) money, the more risk you get from sharing. Many of these companies will pitch the big-picture what and why but not disclose the how, which is the magic. On the other hand, if the what and why are all the value and you share them before you’ve at least somewhat captured them then you risk giving away the opportunity, because the how is just what you’re asking for: the resources.
