What is this for?
Initiating discussions to map the interest of different parties in the ecosystem is preferably done without non-disclosure agreements (NDA). In some cases the speed might be lost or expectations rise to the stratosphere when waiting for the signing of the NDA. In case there is no feasible way of mapping the interest in the ecosystem without disclosing sensitive information the natural way forward is to sign an NDA.
An NDA will most likely become topical later if an idea is taken further and deeper discussions are needed to shape and scope a potential co-creation project.
